PROJECT NAME AIR NATIONAL GUARD SKY HARBOR DATE: 12/11 rO

VARIANCE (;NCLUDE JUSTIFICATION)

PURPOSE:

The purpose of this variance is to document a change in the

analytical procedure and equipment for on-site field screening

analysis of soil boring samples at Sky Harbor National Guard. This

change does not ^ffect the target compounds or the intended use of

the resulting data, but allows a more accurate qualification and

quantification of the target compounds.

CHANGE:

originally as stated in the SAP, a Photovac lOS50 portable gas

chromatograph (GC) using headspace technique was to be used to

determine relative concentrations of the target compounds.

The change will be to replace the 1OS50 GC with a SRI model 8610 GC

equipped with an PID and FID detector in series, purge and trap,

and Peaksimple data system. The onboard integrator of the IOS50

will be replaced with a laptop computer and printer.

VARIANCE (INCLUDE JUSTIICATION)

JUSTIFICATION:

1. The headspace procedure is an indirect method fordetermining the concentration of compounds. The use of

the SRI with the purge and trap allows direct measurement

of the compounds. Because of the direct measurement:

* lower detection limits are obtainable

there will be less variability of measurement

therefore the data will be more accurate

* less sample prep equipment is required causing

a reduction in cost, time, and potentialbiasing and errors 0 *IA

* more accurate simulation of standard laborato-ry procedures

2. Because the SRI utilizes the FID and PID in series it is

easier to more accurately identify and quantify thetarget compounds in a complex chromatograph by comparing

* the results of the two detectors. The 1OS50 only utilizes

the PID thus relying more on the operators interpreta-

tion.iS

VARIANCE (INCLUDE JUSTIFICATION)

JUSTIFICATION (continued):

3. The interfacing and utilization of a laptop computer by

the SRI allows chromatographic data to be stored on

floppy disk in a format that permits the data to be

easily stored an recalled at any future time for reexami-

nation, integration and manipulation. The 10S50 does not

allow this without the addition of extra peripheral

support.

4. The higher level of technology in the SRI allows the

operator to easily and more accurately control the GC

operational parameters thus allowing for more accurate

qualification and quantification of the target compounds

The purpose of thiA procdurc is to define reqairceacou for the coletko of groundwater4 Usmples.

2. BACKGROUND

Metbods used for the collection of roundwater samples icdlde bailing and a variety ofpumping technique. Bdlem are bollow cyladen with undirectional (open up) check valves atthe bottom cud. Some bafles may also be coed or valved at the upper ed& Baile used minenviromental appaittionos are typically contructed of stainim reeL dposable nylon string,diapmable monofilentent polypropylene, Teflon-coated mtainless steel wire, or Teflon, with

4 stainless stel or Tdon being pmreerred. ThM ba is lowered into the well on an acceptableline or coated wire ine until submerged. 7w bailer i thea reuveyed to the surfae for samplecoilecion. lthis procedure de'cribe groundwater umpling with bad-er. For the best rmults,the sequence of sampling is from ilast to mot coazaminated wells. It is preferable for mostsampling events sing balml to have dedicated bailers or enough bailrs to last for I day'sw, h of samiping (normally 6 to S/ld

OEVELOPMENT AND SAMPLING OF LOW RECUARGE WELLS.

1. INTRODUCTION

A low recharge wall can be defined as a well that does not recover to90% of its static water level within 6 to 8 h after being purged. There are

4 many other definitions for low recharge formations; however, this is the onethat the Hazardous Waste Remedial Actions Program (HAZWRAP) will use in itsdiscussion of this issue. Low recharge formations can be found in most of thefollowing environmental scenarios: fine-grained, unconsolidated material suchas clay, silt, shale, or clay in the interstices of larger-grained material; 0or igneous and metamorphic rocks. Under the above conditions, four problemareas surface when it is the task of the hydrogeologist to obtain arepresentative sample of the groundwater from these types of aquifers. Theyare: how do you reduce siltation within the well, how do you develop a lowrecharge well, how do you purge a low recharge well, and when do yoL samplefor volatile organics after purging a low recharge well? *

In the following document, we will discuss these issues and present themost recent discussions with regard to these issues. It is the intent of thisposition paper to make the hydrogeologist aware of the problems associatedwith low recharge wells and to provide some guidance on the above issues. Forthe purpose of this position paper, only low recharge aquifers composed offine-grained, unconsolidated materials will be discussed.

2. SILTATION AND DEYELOPI4ENT

2.1 STATMENDT OF THE PROBLEN

Siltation and development problems are usually relegated tounconsolidated sediment aquifers. These are generally not problems associatedwith slow recharge in consolidated sedimentary, igneous, or metamorphicenvironments. Both of these issues (i.e., siltation and development) will be

discussed concurrently since, in general, they are related issues (i.e.,siltation is largely a problem of ineffective developmnt procedures and/orwell construction techniques).

Siltation Is the process whereby, during well construction and/ordevelopment, small-sized aquifer material (generally smaller than thatretained on a #50 US standard sieve) can be found within the well casing,making the water sample turbid. It is of note that this same grain size range(i.e., less than #50 standard sieve size) makes up over 30% of the aquifersaterial, which is the principal reason why the formation is a slow recharger.This material ends up in the well casing usually by two methods. in thefirst, the fine-grained materials are introduced into the well casing directlyduring well installation. This usually occurs at the same time as the wellscreen, filter pack, and riser pipe are placed at the bottom of the borehole.From the time the borehole drilling is complete and the well Is placed,groundwater will move up into the auger flights, carrying with it anassociated amount of aquifer material due to hydrostatic pressure. Thescreen, casing, and filter pack are introduced directly into this 'soup',thereby introducing the fine-grained material directly into the casing. Alsoduring placement, the aquifer material may become integrated with the filterpack material during placement of the filter pack.

The second siltation problem area occurs during development. Inmonitoring well construction, the purpose of the design of the filter pack isto retain 95 to 100% of the aquifer material. In general, this is not alwaysaccomplished because all too often the well screen size and filter pack sizeare selected before the field investigation (i.e., during the work plandevelopment stage). During this stage, when they suspect slow rechargeaquifers, 10-slot screens with Ottowa #1, Moare 0i, or equivalent filter pickmaterial are selected in advanc, of actual field Information. The developmentprocedure, therefore, must clean out the residual materials in the well casingand must also pull the fine material out of the filter pack since it wasplaced and comingled with aquifer material during placement. Therefore, dueto poor construction design, new aquifer fine-grained material is pulled 4ntothe casing during development because the filter pack material cannot retain95 to 100% of the aquifer material.

This represents a synopsis of the siltation and development problemsassociated with monitoring well construction techniques. The followingsection will discuss some of the more recent published articles relevant tothese issues.

2.2 PALISIED APPROACMES TO SILTATION AND IVELOPMEDT

2.2.1 Well Construction Nethods

The key question to be answered in assessing well construction methodsin low-yield aquifers is, "Can well-designed construction techniques improvethe quality and quantity of groundwater samples from a low recharge aquifer?*.In review of the literature, the following information is submitted forevaluation:

o In a study conducted by Paul, Palmer, and Cherkauer (1988), a seriesof ten wells were placed in glacial tills. Of these wells some hadbeen installed wet (the well was not cleaned out of excess loosematerial before well placement) because of delays in setting thescreens, and some had been installed dry (the loose materials hadbeen removed from the borehole). Of the wells installed wet, thewet wells exhibited 50 to OO times greater turbidity than wellsinstalled dry.

o In an article in Groundwater Age (Wehrmann, 1983), a method that canbe used in clayey environments, where an open borehole can besustained, is to pump water down the inside of the monitoring wellcasing, out the screen, and up the annulus of the borehole. Thisshould be done both before and after the gravel pack is emplaced tofree fine-grained material from the surface of the borehole and thegravel pack materials. Circulation should be continued until thewater coming up the annilus looks clear (Wehrmann, 1983).

4 o According to Nielson (1988). the continuous-slot, wire- wound screenis more effective in preventing formation materials from becomingclogged in the openings. It allows particles slightly smaller thanthe openings to pass freely into the well without wedging in theopening, making these intakes nonclogging.

o In an article by Gass (1989), drilling methods and well constructiontechniques must be adapted to minimize borehole damage before theinstallation of a well screen (commonly referred to as 'skineffect") and a filter pack, or at least to correct borehole damagebefore installation of the well screen and filter pack. Inaddition, it must be understood that the effectiveness of welldevelopment is going to be extremely limited in alleviating thiseffect. To reduce this effect, he suggests several techniques: (1)boring the zone representing the screened interval with a 3- to5-in. Shelby tube, (2) scratching the sides of the borehole with anoversized brush or wire to eliminate the smear effect, and/or (3)developing the low-recharge well with a bailer or small-diametersurge block to achieve gentle agitation of the filter pack so thatany residual fine material that may have been incorporated into thefilter pack during its emplacement can be removed.

2.2.2 Well Construction Materials

In assessing well construction materials, the following information issubmitted for evaluation:

o In an article by Gass (1968). Gass states that the filter packshould be graded, fine to medium sand. Because of the adation,the effective size of the filter pack will be quite small and yetwill still be orders of magnitude more permeable than the formation Sand will not restrict well yield. In almost all cases, a 10-slotscreen will retain 80% to 90% of the filter pack.

o In an article by Nielson (1988), the use of in artificial filterpack in a fine-grained material allows the screen slot size to beconsiderably larger than if the screen were placed in without thefilter pack. This is particularly true where fine slot sizes, whichare designed to hold out formation materials, are either impracticalor not commercially available. The larger screen slot size affordedby the filter pack allows for the collection of adequate volume ofsediment-free samples (Nielson, e9S8).

a Paul, et &l. (1988), states that the function of the filter pack isto stabilize the borehole and to prevent formation materials fromentering the well. They recommend that the proper size of filterpack and screen can be chosen from the grain size distribution curveof the formation by applying the method outlined by Driscoll (1986).In addition, he states that commonly available well screens and sandpacks were not capable of filtering out clay-sized particles foundin fine-grained glacial tills. The optimal well design wouldrequire a silt-sized sand pack and a very fine-meshed screen (<0.05mw). In addition, the wells within his study were constructed ofdifferent types of screens (slotted and continuous). From thiscondition he observed in his glacial till study that surging of thewells that had standard factory slot screens pulled more formationmaterial through the sand pack and into the screen than wells thathad continuous-slot screens. There were no substantial differencesin the turbidity measurements between the three types of wellscreens that had been bailed.

From the information collected, several Issues were not discussed. Oneof these issues is the use of sumps in well construction in low-yieldunconsolidated aquifers. It has been a standing practice during the past 5years that sumps be used in well construction in low-yield aquifers. A sumpis a piece of blank casing placed below the screen and is designed to retainand separate the siltation materials (accumulated fine-grained materialsettling out of suspension) from the screened interval. This device is usedprimarily to keep the entire surface area of the screened interval open toreceive groundwater.

Another issue that has become a standard practice is to ensure anappropriate filter pack thickness. All too often, particularly in shallowgroundwater wells (i.e., those less than 50 ft), a 2-in. well is placed in anominal 4-in. borehole. It is generally agreed that the filter pack thicknessshould equal the well diameter and that it should be tremied into place. Thereasoning behind this position is that an insufficiently large filter packthickness will not retain the large volum of fine- grained material trying toenter the well screen and that a sufficient volume is needed to effectivelyretain or retard this condition.

In addition to the above, Johnson Screens has developed a new screenspecifically designed for low-yield aquifers. This new well screen is calledChannel Pack and is basically two continuously wrapped screens separated by aglass bead filter pack. This screen has not been extensively field tested, soits advantages and disadvantages have not been well established.

2.2.3 Recomendations

Based on the above information, the following construction 'nethods andmaterial specifications are recoumended:

o Filter pack thickness around the well screen should be at least the

same thickness as the diameter of the casing/riser.

o Sumps should be placed below the well screens to act as a sedimenttrap for all low-yield aquifer wells.

o Well screens should be of the continuous slot variety.

o Well screens, casing, and filter pack material should be placed indry wells (i.e., the loose "soupy" material within the drill casingshould be cleaned out or removed before materials placement).

o For optimum design, the filter pack should be graded according tothe aquifer particle size distribution to ensure that the largestpercentage of the aquifer material will be retained by the filterpacK.

o Well screen slot size should be sized to the filter pack. In mostinstances, the filter pack should be sized to retain 95 to 100% ofthe aquifer material.

3. DEVELOPMENT

The main purpose for the development of a well, any well, is to producea turbid-free sample (i.e., to rid the filter pack, screen, and well casing ofthe small particles that remain that are the direct result of the installationprocedure or design). Beyond this, the goal for wells in the water wellindustry differs significantly from the hazardous waste industry. In thewater well industry, the purpose of well development is to obtain maximumyield with the least turbidity for the purpose of water consumption. In thehazardous waste industry, the purpose of development is to obtain a turbid-free sample for the purposes of chemical analysis in the parts per billionrange. Wells designed for pump testing are the exception since increasingwell efficiency may improve the quality of the pump test data. There is asignificant difference between these two goals. In the hazardous wasteindustry, constructing wells for the purpose of high yields tends to be asecondary requirement.

Couin methods of well development in fine-grained materials arepumping, surging, bailing, and the use of compressed air to "blow out" thewell. All of these, or combinations thereof, are acceptable methods withinthe water well industry; however, all do not carry the same level ofconfidence within the hazardous waste industry.

3.2 PUBLISHED INFORMATION ON OEVELOPMENT .

o In the development of wells in glacial tills (Harman, 1988), astainless steel submersible pump was used. The pump was lowered byhand to decrease the turtidity of the water. The pumping rate wasslow and continuous, with a low volume of water being pumped. This

I Ipulled the fine-grained material from the sand pack. The siltsettled to the bottom, and water samples could be taken from the topof the water column. Bailing could be used instead of pumping todevelop the well.

o In tight formations, well development must be sufficiently vigorousto remove fine-gralned particleswithout damaging the well (Marbury and Brazie, 1988). The turbidityof the water needs to be reduced.

o According to Giddings (1985), the steep hydraulic gradient caused bydewatering the well during pumping causes turbulent flow in theaquifer and in the gravel and sand pack, and this results in a veryturbid sample. A surge and block bailer has been successfully usedin developing low recharge wells.

o According to Gass (1988), when an attempt is made to develop a siltor clay formation, the formation will not bridge, and greater b S

* amounts of the formation will be pulled into the well. The same"type of surge energy reaches the formation when a well is purged andsampled with a bailer that fits snugly within the well or when a

4 pump that just fits In a well is rapidly inserted or removed fromthe well. The key to achieving clean samples then is to reduce oreliminate surge energy from reaching the formation.

o The following study was performed by Paul, Palmer, and Cherkauer(1988). In this case, some wells installed in fine-grained glacialtills were surged for 10 imn and then bailed along with wells thatwere bailed only. Water was collected from the screened intervalsIfor turbidity analysis. The hydraulic conductivity of the formationwas sufficiently low that no significant well recovery occurredbetween the time the well was bailed and the sample was taken. Manyof the samples contained a considerable amount of sediment.Baillngs of two wells Indicated a large amount of clay sediment atthe bottom, which was easily agitated, especially when the bailertouched bottom. The wells were then pumped dry to reduce the amountof sediment and were allowed to recover. When samles were taken 4months later, the turbidity had been reduced in all but one well.

o Surging of the wells increased the turbidity. The turbidity was 50to 100 times greater than that in wells that were bailed. Sand packand screens had little effect on the amount of turbidity. In surgedwells, the average turbidity stayed the same between the twosampling periods. In the bailed wells the turbidity decreasedfourfold (Paul, Palmer, and Chorkauer, 1988).

o In the restoration of clogged wells installed In glacial tills,jetting was used, and fine sand, silt, and clay are washed out oftne water-bearing formation. Theturbulence created by the jet brings these fine materials back intothe well through screen openings above and below the point ofoperation (Gass, 1985).

3.2 DEVELOPMEN(T RECOMqMENDATIONS. Based on the above Information and In consideration of the procedures S

previously recommended for well design and installation, the followingdevelooment procedures are recommnded:

o Remove any sediment that may exist within the well casing. This maybe accomplished by using a sand bailer (which most drill rigoperators are familiar with for larger diaeter wells), by usingpump and surge, or by using air lift techniques to remove thesediment in the sediment trap.

o Ideally, the first attempt should be to develop a low yield well bypumping and/or removing water at a rate equal to or less thin therecharge rate of the aquifer. This may be accomplished usingperistaltic pumps, ballers, or bladder pumps for some aquifers. The • 0

a object of this methodology Is to induce water into the well at avery low but constant rate until the water is relatively clear.(NOTE: If bladder pumps are to be used, removing the silt from thewell is critical because of the potential damage to the bladder.)

a If the above techniques cannot be accomplished and the wells arepumped to near dryness even with slow rates of water removal, thenext recommended option is to use a closed-bottom bailer in a pump-and-surge-type scenario. Under this scenario, as the bailer entersthe well, the bailer itself acts as a surge block and forces waterout through the screen, dislodging silt and clay size particles fromthe screen and the filter pack with the intentiw of the particlesreturning through the screen to be removed during the bailing Soperation. The surging activity, however, should not be so vigorousas to extend the surging action into the aquifer materAil itse1f.If during this process the well is pumped to dryness, the aboveprocedure say have to be repeated one to two additional times toobtain a smple that is relatively sediment free. A specificapplication of this approach is to develop the well in stages (2 to3 ft at a time, from the bottom up). In this the surge strokeshould not exceed the surged interval.

o At the completion of the development of a well, a well recovery testshould be performd. This test Is similar to a rising head slugtest. These data will assist the field hydrogeologist in thedevelopment of other wells and in the scheduling and planning of

U purge and sample activitýes. It is not implied, however, that well ur,recovery tests should be conducted on every well. The discretior ofthe use of this test is held within the purview of the fieldhydrogeclogist and the HAZWRAP project team.

4. PURGING AND SAMPLING

4.1 PURGING

Perhaps the most critical component of collecting a representativesample of the aquifer water occurs during the purging process. The mainpurpose of purging a well is to remove the stagnant water from the well casingand borehole and to replace it with groundwater that more accurately reflectschemical conditions within the aquifer. A lot of discussion has focused onthis issue. The rationale for purging is to help remove fine-grained

p particles in the well and sand pack that may potentially enter tne well screenand the sample (Paul, Palmer, and Cherkauer, 1988). (NOTE: All operationsneed to be performed with materials and equipment that have been thoroughlycleaned to avoid introducing c€,ntaiminaton into the well. This is especially

r critical in low-yield wells because even a minute amount of contaminant may4result in relatively high concentrations in samples.)

The following is a presentation of discussions on this issue that haveoccurred in technical publications over the past several years:

o According to the Wisconsin Oepartment of Natural Resources Guidance(Llndorf, Feld, CUnnelly, 1987), the most straightforward method forvemoving all of the stagnant water from wells screened in lowpermeability formations is to pump or bail the well dry. Thisprocedure may be the best way to ensure that all of the stagnant

, water In the well has been exchanged with water from the aquifer.* After purging, the well should be allowed to fully recover and can

be purged a second time if needed.

o The Environmental Protection Agency (EPA) Technical EnforcementGuidance Document (1986) is similar to this. It states that whenlow-yield wells are being developed, they should be pimped to

* dryness once. If the recharge rate of the well causes the formationwater to vigorousl' cascade down the intake screen and accelerate

a the loss of volatii;s, the well should not be pumped dry. If thisis anticipated, three casing vblumes should be purged from the well

5 at a rate that does not cause the recharge water to be excessivelyagitated.

o If a monitoring well is drained completely during purging, the4 formation water will be exposed to the atmosphere as it enters the, well. This may cause a 10% loss of volatiles within 5 min and a 70%

loss within I h. Protocols should avoid draining the well mnd anyunnecessary exposure of the sample to the atmosphere, especiallywhen combined with turbulence (P4cAlary and Barker, 1987).

So If the sand pack around screens is drained during purging orflushing, the formation water will flow into the well by cascadingthrough the headspace in the dewatered sand filter pack. Somevolatilization can be expected to affect the groundwater even beforea sample can be collected (McAlary and Barker, 1987).

o The amount of recharge may limit the amount of sample that can becollected. Frequent purging will likely dewater the saturated zone,causing the well to go dry for a period of time. In wells thatrequire a very long period of time to recharge, the Interval betweensampling events may not be sufficient to allow full recovery tostatic water-level conditions. In such cases, an annual orsemiannual sampling event may be more appropriate than quarterlyevents (Narbury and Brazie, 1988).

o The results of a laboratory standing-column volatilization test byMcAlary and Barker (1987) showed that losses will reach 10% within 1h and 99% in I month. The standing water should therefore be

_ thoroughly purged before sampling. In the context of a samplingevent, It may be acceptable in moderately low permeability materialsto return for sampling of volatile organics several hours afterpurging, provided that the calm surface of the water in the casingwas the only exposure of the sample to headspace.

4.2 SAMPLING

The problems of purging and saMpling low recharge wells are mutuallyrelated events. The type of purging a field team performs may affect thesampling effort. In addition, within the literature, it is not clear as tothe best time to sample for volatile organics. The following are submittedfor evaluation and review:

o In low-yielding bedrock aquifers, wells may be pumped dry byremoving only one bore volume of water. If the water- bearingfractures are located just below the static water table level, thewell will refill by cascading water entering the bore and falling tothe bottm. This alters the dissolved gases in the water andincreases the dissolved oxygen content. Many monitoring parametersare sensitive to this alteration, and it can lead tomisrepresentative sampling (Giddings, 1985).

o A water-level monitoring period of several hours or days may berequired to determine whether the well bore is making water or todetermine If the water level will return to static water-levelconditions. In these instances, it may be possible to remove onlyone casing volume before sampling (Narbury and Brazie, 1988).

!

!

10 4o Samples should be collected as soon as there is a sufficient amount

of water in the well bore in order to get a sample that Isrepresentative of the formation water (Llndorf, Fold, Connelly,1987).

o According to the EPA Guidance, as soon as the well recovers, theorder of sampling should be pH, volatiles, oxidation-reduction,semivolatiles, pestictdes/polychlorinated biphenyls (PCBs), metals,and inorganic compounds. For wells with a recovery time of greater 0than 3 h, samples should be taken in order of their volatility assoon as there is a sufficient volume of water available for a samplefor each parameter, Parameters that are not pH sensitive or subjectto volatillzation should be taken last.

o In the sampling of naturally purged wells (Robin and Gillham, 1987), 1results Indicated that a representative sample could be obtainedfrom the screened interval through the use of dedicated samplingdevice, such as a syringe sampler, The intake would need to belocated near the bottom of the screened interval. Tne voltme of thesample would have to be significantly less than the volume of thescreened interval. Some contamination could result fromdisplacement of water by the sampling device. In this study, asscreen lengths became shorter (screen lengths of 1, 2, and 5 It),the first samples were progressively more contaminated.

o In a recent article by Herzon et al. (1988) eleven 2-fn. 00stainless steel wells were developed using bailers and a diaphragmpump. Bailers were used to extract water and to act as surge blocksto draw in fine materials. This procedure was repeated four timesfor each well. The diaphragm pumps were used to pump the wells todryness so that a rising-head test could be performed on each well.Samples were retrieved at several different times after purging.The final conclusions were that wells in low- yield aquifers shouldbe purged before sampling and that concentrations of volatileorganics in the sample collected 4 h after purging contained thehighest volatile organic concentrations.

5. EQUIPI•ET FOR DEVELOPMENT, "=INI&, AND SAUPLING

To minimize the Introduction of contamination into the well, positivegas displacement Teflon bladder pumps are recommended for purging wells.Teflon or stainless steel bailers are also recommended purglni equipment.Where these devices can't be used, peristaltic pumps, gas-lift pumps,centrifugal puyps, and venturt pumps may be used. Where a suMling devicerequires an intake line, or discharge line, the composition of the line shouldbe Teflon, polyethylene lined with Teflon, or polyethylene. Where a samplingdevice requires a support line to the surface (as in bailers), the supportline should be single- strand, stainless steel wire, Teflon-coated stainless

4 steel wire (single strand or braided), or a stainless steel leader attached tomonofilament polyethylene line.

11 4Pumping rates for peristaltic pumps are typically less than ISOO mL/min.

Other types of pumps produce volatilization and high-pressure differentlals,causing variability in the analysis of pH, specific conductance, metals, andvolatile organic samples. They are, however, acceptable for purging wells(EPA Guidance, 1986). S

The equipment required for jet development includes a jetting tool withI' two or more nozzles, a high-pressure pump, a high-pressure hose, and a supply

of water. The nozzles should be evenly spaced on the jetting tool (Gass,1985).

The valve-type plunger could be used in tight formations because it hasa lighter surging action. A bailer can be used along with the plunger (Gass,t 1985).

In Paul, Palmer, and Cherkauer, the surging process (in fine-gralnedglacial tills) was performed with a length of polyvinyl chloride (PVC)electrical conduit fitted with an oversized rubber stopper. The rubberstopper was small enough to allow passage through the well but large enough toforce water before It. A peristaltic sampling pump was used to remove the

bottom sediment from the monitoring wells.

In a study by Griffin et &l. (1988) on the collection of volatileorganics from fine-grained materials, samples were collected using a double-check valve, leflon bailer with a bottom-draining device. For shallow,

j small-diameter wells with low yields, evacuation of the well by a bailer isfeasible. Syringes can also be used to sample water from low hydrostatic headaquifers because they only remove a small volume of water from the well(Nielson, 1985).

6. RECO9UIEDED PROCEDURES FOR PURGING AN SAMPLING

The following purge and sample procedures are based on a review of theinformation provided above, known characteristics of monitoring well rechargeand well dynamics, and the best available technology. The succeedinginformation is provided to act as a starting point with regard to planning andexecution of sampling activities within low recharge environments, It isunderstood that as field activities commence, minor revisions to the purge andsample activities may be required based on site- specific information;however, the following scenario should be used and planned for during theI early stages of field activity development.

The following procedures are reconmended for purging and sampling of lowrecharge aquifers:

o As a general rule, under low recharge conditions, purge and sampleactivities snould not occur for a minimum of

I 7 d after well development. This period may be extended, dependentS upon very low recharge conditions and varying site conditions.

o Purging and sampling are considered by HAZWRAP to be mutuallyinclusive activities (i.e., they are not separate events).Therefore, the comon field activity of purging all wells first thensampling is not considered to be the best available procedure.Purging and sampling should be considered, in terms of schedule, asone event.

ro Purging Degins with placing the pump or purge device at the top ufthe water column to remove the water from the well casing and

,1 borehole from the top down.

o Purge rates should be at a value less than that indicated from thewell development recharge rate recorded at the conclusion of welldevelopment. Under low recharge conditions, this rate will rarelyexceed 0.S gal/min. This low purge rate will permit the water withinthe casing and borehole to exchange without punping the well todryness or appreciably depressing the static water level.

o If the above condition cannot be met, the entire volume of waterwithin the well casing and borehole should be removed at the ratedetermined above. f it is already known that the well can bepumped down without appreciable recharge, the rate specified aboveshould not be exceeded. Excessive pumpiln will only cause turbidityproblems when eventual recharge and sampling begin. (NOTE: As areminder, under the well construction recommendations, each wellwill exhibit a 2- to 5-ft sediment trap to be located below thescreen. Therefore, the sediment trap should be removed of built-upsediment before actual purging and sampling).

o If the well does not recover to 90% of its static water level within6 to 8 h, only one borehole volume need be removed. If the wellrecovers in less time, purge activities should be repeated at leastone more time. At the conclusion of the Initial purge activities,if significant fines have accumulated In the sediment trap, thesefines should be removed before the second purge activity.

o Sampling from wells in which the static water level was notappreciably depressed is to occur immediately after purge activitiesare completed (within 3 h as a genral rule). Sampling from wells,in which the water was Lompletely remved from the well or therecovery time exceeds 3 h, will occur (for volatiles and pH and

4 m oxidation-reduction sensitive analytes) when the water level hasj reached a point above the bottom of the screen such that a

sufficient sample can be retrieved. Sampling for other nonsensitiveanalytes my occur at some point later as the well has had time tomore completely recover and provide sufficient sample. Ifsufficient ample has not become available within 24 h, the HAZWRAPProject Manager should be immediately informed so that a decisioncan be made as to the disposition of this condition.

I HAZARDOUS WASTE REMEDIAL ACTIONS PROGRAMSTANDARD OPERATING PROCEDURE 4WELL DEVELOPMENT AND PURGING

g 1. OBJECTIVE

The objective of this procedure is to define the procedural requirements for wellI development and purging.

S2. BACKGROUND

Monitor wells are developed to remove skin (i.e., near-well-bore formation damage) andto settle and remove fines from the filter pack. Wells should not be developed for 24 h aftercompletion when a cement bentonite grout is used to seal the annular space. However, wellsmay be developed before grouting if conditions warrant. Wells are purged immediately before 4groundwater sampling to remove stagnant water and a sample representative of groundwaterconditions. Wells should be sampled within 3 h of purging (optimum) to 24 h after purging(maximum, for low recharge conditions).

3. RESPONSIBILITIES

Sit Managtc The Site Manager is responsible for ensuring that field personnel aretrained in the use of this procedure and for verifying that development and purging are carriedout in accordance with this procedure.

I Project FReld Geolo"t: The Project Field Geologist is responsible for complying with

this procedure.

4. REQUIRED EQUIPMENTI* Pump, pump tubing, or bailer and rope or wire line.* Power source (e.g., generator), if required.I Water-level meter or weighted surveyor's tape.e Temperature, conductivity, pH. and/or dissolved oxygen meters (for Sect. 5.2 below).* Personnel protective equipment as specified in the site-specific health and safety plan.

5. PROCEDURES

5.1 WELL DEVELOPMENT

"The following steps must be followed when developing wells:4

1. Put on personnel protective clothing and equipment as specified in the site-specifichealth and safety plan.

- 2. Open and check the condition of the wellhead, including the condition of thesurveyed reference mark, if any.

3. Determine the depth to static water level and depth to bottom of the casing.4. Prepare the necessary equipment for developing the well. There are a number of

techniques that can be used to develop a welL Some of the more common methodsare bailing, overpumping, backwashing" mechanical surging, surge and pump, and

a• , high-velocity jetting. All of these procedures are acceptable; however, final approvalof the development method rests with the appropriateness of a specific method tothe site and the Hazardous Waste Remedial Actions Program (HAZWRAP) project

, manager.5. For screened intervals longer than 10 ft, develop the well in 2- to 3-ft intervals from

-, • bottom to top. This will ensure proper packaging in the filter pack. 'Note It isgood practic to decelop all samcnW and ifitm-packed well n stage.

6. Continue well development until produced water is clear and free of suspendedsolids. Record pertinent data in the field logbook and on appropriate well

4 development form per HAZWRAP SOP 1, Parts A and B, respectively.7. Remove the pump assembly or bailers from the well, decontaminate (if required), and

-1 * clean up the site. Lock the well cover before leaving. Dispose of produced water asrequired by the project work plan.

5.2 VOLUMETRIC METHOD OF WELL PURGING4

The following steps should be followed when purging a well by the volumetric method:

1. Put on personnel protective clothing and equipment as specified in the site-specifichealth and safety plan.

S2. Open the well cover and check the condition of the wellhead, including the conditionof the surveyed reference mark, if any.

3. Determine the depth to static water level and depth to bottom of well string.Calculate the well volume (volume of water within the well bore) using the followingformula (or equivalent):

I where

D = casing diameter in feet. (NOTE: This equation is used for grouted wells withshort screens For wells with long screens and/or ungrouted wells, then D =borehole diameter in feet.)SdH - the distance from well bottom to static water level in feet.

Note these data and calculations in the field logbook.

4. Prepare the pump and tubing, or bailer, and lower it into the casing.5. Remove the number of well volumes specified in the project plans. Generally, three

to five well volumes will be required. In low-recharge aquifers, the well willcommonly pump or bail to dryness before three well volumes of water are removed.If this is the case, there is no need to continue with purging operations (HAZWRAPPosition Paper No. 2). Record pertinent data (e.g., water volume) in the field

i 6 logbook.6. Remove the pump assembly or bailer from the well, decontaminate it (if required),

and clean up the site. Lock the well cover before leaving. Dispose of producedI water as required by the project work plan.

4 5.3 INDICATOR PARAMETER METHOD OF WELL PURGING

1. Put on personnel protective clothing and equipment as specified in the site-specifichealth and safety plan.

2. Open the well cover and check the condition of the wellhead, including the conditionof the surveyed reference mark. if any.

3. Determine the depth to static water level and depth to bottom. Lower the probe(s)of the indicator meters (e.g., temperature, conductivity) into the water to a pointnear (but not at) the well bottom or use the flow-through system for indicatorparameter meuurement. Alternatively, set up surface probe(s) (e.g., pH, dissolvedoxygen) at the discharge orifice or dedicated probe port of the pump assembly orwithin the flow-through chamber. Allow subsurface probe(s) to equilibrate accordingto manufacturer's specifications. Record the equilibrated readings in the fieldlogbook together with the time.

4. Assemble the pump and tubing, or bailer, and lower into the casing.5. Begin pumping or bailing the well. Record indicator parameter readings at

predetermined intervals. Maintain a record of the approximate volumes of waterproduced.

& Continue pumping or bailing until indicator parameter readings remain stable withint10% for three consecutive recording intervals. Purging should continue until thedischarge stream is clear. In low-recharge aquifers the well may pump or bail to

dryness before indicator parameters stabilize. In this case, there is no need tocontinue purging. Record pertinent data (e.g., water volume) in the field logbook.

7. Remove the pump assembly or bailer from the well, decontaminate (if required), andclean up the site. Lock the well cover before leaving. Dispose of produced water asrequired by the project work plan.

6. RESTRICrIONS•LIMTATIONS S

Where flammable free or emulsified product is expected or known to est on or ingroundwater, use only intrinsically safe electrical devices and place portable power sources (e.g.,generators) 50 ft or more from the wellhead and disposal drums.

STo Don Willen, Project Manager Date September 18, 1990

From Steve Sares, Principal Hydrogeologist

Sub]ect Preliminary Review of Hydrogeologic Data for FacilitiesAdjacent to Sky Harbor Air National Guard Base

I. INTRODUCTION

In accordance with your request, I have prepared a brief summary of

data collection activities and analysis of hydrogeologic data for0 facilities adjacent to the Sky Harbor Air National Guard facilities

at the Phoenix, Arizona Airport (the Base). These activities andpreliminary conclusions regarding the hydrogeology of the vicinityare presented below.

aThe goal of this data collection and review effort is to aid indetermining appropriate monitoring-well placement and designspecifications for wells to be installed during the Base SiteInvestigation (SI). As you are aware, there has been muchdiscussion of appropriate depth, screen interval, and location forthe SI monitoring wells.

Data collection activities for this task were conducted betweenJuly 9 and 11, 1990 and consisted of locating and obtainingavailable potentiometric records for facilities generally within

0 one and one-half miles of the Base. Field activities such asverification of well locations or measurement of water levels werenot conducted during data collection activities. All findings

* presented below are based on the assumption that data collection,reduction, calculation, and presentation contained in the recordsare accurate and complete. Records were obtained from the

* following agencies:

City of Phoenix Environmental Services Department

* "Arizona Department of Environmental Quality (ADEQ)

Arizona Department of Water Resources (ADWR)

In addition, a Remedial Investigation report was located at apublic library which contained hydrogeologic information relevantto the Air National Guard facilities at the Papago MilizaryReservation (Papago). The sources of information and relevanthydrogeologic information are further discussed below.

I II. DATA SOURCE BIBLIOGRAPHY

Six primary sources of information were identified and evaluated inthis effort. Selected pages of reports and files were extractedand copied from the sources listed below:

0 A. Summary of the Phase II Site Investigation for the City* of Phoenix at the West Sky Harbor Fuel Storage Facility

and Vicinity, Phoenix Sky Harbor International Airport,* Phoenix, Arizona. (May 31, 1990), Groundwater* Technology, Inc. Received from Mr. Donn Stoltzfus, City

of Phoenix.

B. ADEQ files for Avis Sky Harbor, ADEQ File No. 4715.122.Received from Mr. Douglas Jamison, ADEQ.

C. ADEQ files for Garrett General Aviation Services* Division, ADEQ File No. 4715.355. Received from Mr.

Douglas Jamison, ADEQ.

D. Draft Remedial Action Plan for Del Rio Landfill, City ofPhoenix, Arizona (February 23, 1990), Dames and Moore.Received from Mr. Donn Stoltzfus, City of Phoenix.

E. Estes Landfill Hydrogeology. Received from Mr. DonnStoltzfus, City of Phoenix.

F. Remedial Investigation Report, 52nd Street RI/FS,Phoenix, Arizona for Motorola, Inc. (June 1987), Damesand Moore. Copy at Saguaro Library, Phoenix, Arizona.

In addition to the above referenced documents, several others werereviewed and received from the agencies listed above. Informationin the additional documents either duplicated information presentedbelow or are for facilities remote from the Base. Mr. David Annisof the ADWR also provided much valuable discussion regardingfacilities and history of hydrogeologic investigations in the areaadjacent to the Base.

II. FINDINGS

Results of the hydrogeologic investigation at the Sky Harbor fuelfacilities (Reference A) are likely to be directly applicable tothe SI as the fuel facilities are located approximately 4,300 feet(0.8 miles) from the center of the Base on a bearing of fiftydegrees west of north (N 50 W). These findings are summarizedbelow.

September 18, 1990Page 3

Five monitoring wells, 90 feet deep, were installed atthe site in March and April 1990. The water level ineach well is approximately 71 feet below grade or at anelevation of 1,038 to 1,036 feet above Mean Sea Level(feet MSL).

Detailed casing elevations and depth to water were notincluded in the information provided, however, a sitegradient map indicates a due westerly groundwater flowdi.Lction at a gradient of approximately 0.002 or 10.9 ftper mile.

Lithologic logs indicate mixed, unindurated alluvium atthe site consisting generally of sand to silt in the 0-5foot depth interval, sand to pebbles in the 5-15 footinterval, and sand to cobbles below 15 feet.

Avis Car Rental facility at Sky Harbor is conducting aninvestigation for a fuel release (Reference B). The Avis facilityis located approximately 7,600 feet (1.4 miles) from the center ofthe Base on a bearing of N 82 W. Findings from these files aresummarized below.

The depth to water, measured on 24 Nov 87 ranges from61.26 to 64.51 feet below the surface, this correspondsto an approximate elevation of 1,035 to 1,039 feet MSL.

The groundwater flow direction at the site is generallywest with the flow direction diverging to northwest andsouthwest west of the Avis site. Reports suggest thatthe divergence may be caused by an Arizona Department ofTransportation (ADOT) dewatering project located in linewith 21st Street between Buckeye Road and the Salt River.

The ADOT project was in operation at the time thematerial in the files was prepared (1987). At that timethe dewatering system consisted of 11 wells each pumpingat approximately 1,500 gallons per minute.

The U.S. Geological Survey (USGS) conducted a pump testduring the dewatering project and determined the aquifertransmissivity (T) to be 194,000 GPD/ft, and hydraulicconductivity (K) to be 1,200 GPD/ft, using a saturatedthickness of 150 feet.

Garrett General Aviation Services Division operates a facilitylocated approximately 6,300 feet (1.2 miles) southwest of thecenter of the Base on a bearing of S 73 W. This facility isconducting an investigation for fuel and solvent release (ReferenceC). Findings from the Garrett files are summarized below.

The depth to groundwater was measured to be approximately •55.5 to 57.9 feet below grade or at an elevation of 1,044to 1,042 feet MSL on 5 Dec 88.

Garrett has presented the groundwater flow direction tobe northwesterly (N 36 W). The ADEQ disagrees with thisintexpretation and states that the ground water flowdirection at Garrett is North 80 East. This direction isinconsistent with the regional flow direction asindicated by all other references from the area. I havereviewed the available potentiometric data at Garrett andthe flow direction, based on three-point solutions rangesfrom N 15 W to S 36 E depending on the combination oiwells used. Thus the data from Garrett appearsinconsistent and should not be relied upon for the BaseSI.

The City of Phoenix owns a landfill located approximately 14,600 5feet (2.8 miles) southwest of the Base on a bearing of S 74 W.This landfill is called the Del Rio or 16th Street landfill and itis located on the south edge of the Salt River (Reference D).Findings from the files are presented below.

Depth to groundwater is typically 35 to 40 feet belowground level or at an elevation of 1,045 t, 1,040 feetMSL.

Water levels in wells have demonstrated fluctuation of upto 28.7 feet in a single well over a period of ten years.The peak water level (all wells) was 1,055.6 feet MSL 5(approximately 24 feet below ground level). The minimumwater level over the same period was 1,020.51 feet MSL(approximately 59.5 feet below ground level).

Hydrographs for monitoring wells over the period from1979 to 1990 indicate that water elevations in wells in 5the period 1986 to 1990 are at the lower end of the range(1,025 to 1,045) while during the period 1983 to 1986they were in peak ranges (1,055 to 1,045). In general,water levels in these wells have declined approximately20 feet from the 1983 peaks to the 1990 lows or anaverage of 2.8 feet per year. Prior to the 1983 peak 5levels, water levels were in the 1,030 foot range as late

as 1982. Water levels in monitoring wells demonstrate a

strong correlation to flows in the Salt River, thus acontinued decline in water levels cannot be projected.

Reference D provided several potentiometric maps for theDel Rio Landfill. These maps were prepared by theauthors of the report by unknown means. Based on the

Ii maps presented, the groundwater flow direction averagesa bearing of N 60 W (300 degrees azimuth) for nine maps,•iresented in the report under dry river conditions. Onepotentiometric map representing conditions of flow in theriver was also presented, the groundwater flow directionin this case was S 57 W (213 degrees azimuth).

The City of Phoenix also owns another landfill southeast of theBase. The Estes Landfill is located approximately 6,500 feet (1.2

4 miles) from the Base on a bearing of S 82 E (Reference E).

Depth to water at the Estes Landfill is typically 40 to60 feet below ground level or at an elevation of 1,080 to1,060 feet MSL.

4 Water levels in monitoring wells also fluctuate inassociation with flow in the River at the Estes Landfill.The maximum fluctuation observed in a single well over aperiod of seven years is 43.77 feet.

III. DISCUSSION AND CONCLUSIONS

A. MONITORING WELL SCREEN INTERVAL

Sky Harbor

The Base is located in an area with ground elevation ofapproximately 1,110 feet MSL. The current monitoring well designcalls for 50 feet of screen to be placed 30 feet below the ambient

O water table and 20 feet above the water table.

Data from the Sky Harbor fuel facility investigation and othersites in the area suggest that the water table will be encounteredat a depth of approximately 70 feet below the surface or at anelevation or 1,040 feet MSL. This configuration will require soil

4 borings to be extended to approximately 100 feet below the groundsurface for well construction. The well bottom will be located atan elevation of approximately 1,010 feet MSL and the top of thescreen interval will be approximately 50 feet below ground or 1,060feet MSL.

* Using data from the Del Rio Landfill (Reference D) during periodsof prolonged flow in the Salt River, water levels may be expectedto rise as much as 20 to 25 feet. Assuming a 20 foot rise in thewater table due to flow in the river, the water table elevation atthe Base would be approximately 1,060 feet MSL. This is at thelevel of the top of screen in proposed monitoring wells. Based on

4 this scenario, it may be prudent to set the top of screen at anelevation of 1,C65 or 25 feet above the expected water table.

I

ka

A screen length of 50 feet would place the bottom of the well at1,015 feet or 25 feet below the expected water table. Assumingfive feet of saturated well are required for representative samplesto be collected, the water table could go as low as 1,020 feet andthe wells would remain useful. This is approximately the lowestlevel recorded at any of the surrounding areas, the 1,020 levelalso represents over seven years of useful life at an average watertable decline rate of 2.8 feet per year. The 50-foot-long screenproposed should be adequate for the objectives of the SI and futureuse.

Papago

The current proposed monitoring well design for Papago wells is thesame as the wells designed for the Base; thirty feet of screen tobe placed within the water table. Given the information presentedin Reference F, above, it is likely that upon completion ofpiezometers at Papago and measurement of water levels, it will bedesirable to modify the screened interval to allow 15 feet belowand five to ten feet above the water table. This interval shouldbe sufficient to accommodate anticipated water-level fluctuations.

B. MONITORING WELL PLACEMENTS

Sky Harbor

6 Proposed monitoring well locations for the Base SI were developedassuming a westerly (N 90 W) groundwater flow direction. Thepossibility of significant deviation from this direction motivatedthe collection of existing data to verify the assumption ofwesterly grour-;ater flow.

Because the potentiometric data obtained during this effort werenot collected from a single point in time, they cannot be used inpreparation of an area potentiometric map, therefore accurateprediction of groundwater flow direction for the base cannot bemade.

Generally, published groundwater flow directions are in a westerly(S 83 W) to northwesterly (N 60 W) direction during no-flowconditions in the Salt River. The exceptions to this condition are

p during flow in the river and one combination of water levels at theGarrett Aviation facility. Groundwater flow direction during river

* flow is discussed below. The Garrett data are inconsistent, usingthe same four data points groundwater flow direction variation of

i!

*

F

Mr. Don WillenSeptember 18, 1990Page 8

140 degrees can be obtained. It is advisable not to utilize thisdata in placement of SI wells unless separate conformation ofeasterly flow directions can be made.

I

The available data indicate that during periods of river flow, thegroundwater gradient on the south side of the river is in asouthwesterly direction (S 57 W to S 51 W). It follows, assumingflow in the river creates a mound in the water table coincidentwith the axis of the river, that the groundwater flow directionnorth of the river would be in a northwest (N 57 W to N 51 W)direction during periods of river flow.

Using the above discussion it is reasonable to assume thatgroundwater flow direction around the Base is primarily westerly,with a maximum northerly component of 30 degrees north of westduring no-flow in the river and a maximum northerly component of 39degrees during periods of flow in the river. Given this analysisit is recommended that the initial plan of piezometer installationand flow direction determination prior to well placement be adheredto for the SI. It may be prudent to periodically measure waterlevels in elevation-surveyed wells from surrounding facilities todevelop an area potentiometric map during the SI. Any offsitemonitoring should be limited to facilities within a one and one-half to two mile radius of the Base.

Papago

Proposed monitoring well locations for Papago were developedassuming a westerly groundwater flow direction. Should piezometricinformation agree with the data contained in Reference F,indicating a southwesterly flow direction, it may be desirable torelocate well MW4-03 to the west side of Building 112. Howeverthis determination should be postponed until site-specificpotentiometric data are available.

I GEOPHYSICAL SURVEYii,

1.0 Introduction_

A geophysical survey was conducted from December 13 to 23, 1990 at Sky Harbor Interna-

4 tional Airport (lAP) in Phoenix, Arizona. The survey was conducted in two phases. The firstphase involved the geophysical clearance of all proposed soil organic vapor (SOV) sampling

points and soil boring and monitoring well locations of underground pipelines and utilities atSite 1 (JP-4 Hydrant Area), Site 2 (Hazardous Waste Storage Area), Site 3 (Fuel Bladder

4 Area), Site 4 (107TCS Hazardous Waste Collection Area), and Site 5 (Ammunition DisposalArea). Electromagnetic (EM) utility locators and ground penetrating radar (GPR) methods

were used during this phase of the investigation.

* During the second phase of the geophysical investigation, EM and GPR surveys wereconducted at Site 5 to locate buried ammunition. In 1980, live 50-caliber ammunition was

discovered in excavations during installation of a closed circuit television (CCT) system(AZANG ;990). Ammunition was found in two areas shown in Figure 1. The Preliminary

4 Assessment (PA) reported that ammunition was found at depths ranging from 6 to 8 feet at alocation approximately 50 feet south of the CCT trench locations (HMTC, 1988).

The locations of the Site 5 EM and GPR surveys are shown in Figure 1. Several modifica-

I tions ,o the original survey design were necessary based on unanticipated field conditions. Asoriginally planned, magnetic and EM surveys were to be the primary means of locating buriedammunition with the use of GPR restricted to problem areas or areas requiring additional

data. However, due to the abundance of surface structures, vehicles, and underground4 utilities, EM surveying was conducted only in areas relatively uncongested with metallic

material. The magnetic survey was not performed because of interference from unwanted

sources over much of the area of the site. As a consequence, GPR was used as the primaryexploration tool. In addition, the EM survey was extended 130 feet to the west to include a

- more open area approximating background soil conductivity conditions.

geophysical survey at Site 5 (Ammunitions Disposal Area). A Geophysical Survey Systems,

Inc. (GSSI) Subsurface Interface Radar System 10, which was equipped with 120-, 300-, and W

500-MHz monostotic antennae, a Radio Detection Model RD-400 electromagnetic cable 0

locator, and a Metrotech Model 810 pipe and cable detector were used during the geophysical

clearance phase. The GPR unit and a Geonics EM-31DL (EM-31) with a digital data logger

were used during the geophysical surveys at Site 5. Detailed equipment descriptions and

supporting theory are included in Appendix A.

2.1 Geophysical Clearance

Geophysical field procedures used to clear drilling locations of subsurface obstructions are

described in this section. First, all utilities near the drilling point evident from utility maps

and visual observation were traced by placing the Metrotech or RD-400 transmitter on the

line, delineating the line using the receiver, and marking it on the ground surface using

orange surveyor's paint. Individual drilling locations were then cleared by holding the

transmitter on the line and circling with the receiver at a radius of approximately 40 feet.

When a line was located using the receiver, the transmitter was relocated to that point and the

line was traced and marked in the vicinity of the drill point. If a utility was found within

approximately 3 feet of the drilling location, it was moved and the entire procedure repeated.Finally, in areas where nonmetallic pipes or large numbers of utilities were present, two * S

perpendicular GPR profiles were conducted over the drilling point using the 120-, 300-,

and/or 500-MHz antennae. If additional utilities were located within 3 feet of the drilling

location, the boring was moved and the clearance procedures repeated.

2.2 Geophysical Survey: Site 5 - Ammunition Disposal Area

EM and GPR surveys were conducted at Site 5 to determine the possible location of buried

ammunition disposed of during the 1950s.

To provide spatial control, a 20- by 20-foot grid was marked with surveyors paint in the area

of interest. The location of the base grid relative to permanent site features is shown in

Figure 1.

Readings of conductivity and in-phase component field strength, as measured by the EM-31,

were collected at 5-foot intervals along both north-south and east-west lines spaced 20 feet

apart. The locations of the EM survey lines are shown in Figure 1. Data were stored in adigital data logger and downloaded to a laptop computer at the completion of the survey.

Many of the EM survey lines were conducted in segments due to buildings and other

KNVWP451/09-03-91/DRAFT #2 2

Smml 0 u m am m0...

obstructions. For example, data were not collected in the Liquid Oxygen Storage Area

(Building No. 46 and its perimeter) because of the adverse effects of the oxygen tanks and 3)

surrounding fences.

The GPR survey was concentrated in the vicinity of the Ammunition Dump and in the areas

where ammunition was discovered during trench excavations in 1980. The locations of the

GPR profiles are shown in Figure 1. All GPR profiles within the Liquid Oxygen Storage S

Area (Lines GPR-1 through GPR-9) were conducted with both the 300- and 120-MHz

antennae All other GPR profiles were conducted with only the 300-MHz antenna. All GPR

data were stored on digital tape for later processing.

To allow an accurate interpretation of the geophysical data, the locations of all surface

metallic objects were accurately plotted relative to the base grid as shown in Figure 2.

3.0 Data Processing and Interpretation 5

Computer-generated plots of the EM profiles are included in Appendix B. In-phase and

conductivity anomalies were tracked from line to line when possible, or noted as single

anomalies. Some portions of the data severely affected by buildings and vehicles were

deleted before plotting.

Field mapping of surface metallic objects made it possible to distinguish anomalies caused by

known sources from those caused by buried pipelines and other conductive objects. Contour

maps of the EM data were not generated because a significant portion of the data was

affected by buried objects and surface features.

Color plots of the GPR sections were made for interpretation, with a color scale proportional

to the amplitude of the reflected signal. Two-way travel times were converted to depths

using an assumed relative dielectric constant of five. Anomalies due to known sources, such

as surface objects or buried pipes, are noted on the profiles. Examples of interpreted GPR

sections are included in Appendix C.

* 4.0 Discussion and Results

The first phase of geophysical surveying involving geophysical clearance of subsurface

obstructions to drilling resulted in the successful installation of all SOV probes, soil borings, 4

and monitoring wells.

In the second phase of geophysical surveying, EM and GPR were used to assess the likeli-

hood of additional buried ammunition at Site 5. The results of the EM survey are presented

graphically in Appendix B and are summarized in Figure 2. After discarding in-phase and

conductivity anomalies due to known sources, significant remaining anomalies were observed

to exhibit continuity between parallel survey lines, and because of their linear character are

interpreted to be caused by underground utilities.

GPR profiles are presented in Appendix C. Assuming a relative dielectric constant of five for

geologic materials at Site 5, effective depth of penetration was approximately 5 feet for the

300 MHz antenna and approximately 12 feet for the 120 MHz antenna. Although the

penetration depth of the 120 MHz antenna was significantly greater, its resolution was

correspondingly lower then the 300 MHz model. In addition, the 120 MHz antenna was not

shielded, and therefore was subject to signal interference from aboveground sources. An

example of this can be seen in Figure C-4, in which a fence is responsible for a hyperbolic

reflection between 75 and 90 feet. Because of these shortcomings, it is not likely that the 120

MHz antenna was capable of resolving containerized ammunition.

The anomalies observed on GPR profiles north of monitoring well MW5-02 were compared

with known surface and subsurface features as shown in Figure 2. Two significant anomalies

could not be related to known features. Anomaly A, shown in Figures 2 and C-2, is located

at approximately 19 feet south on Line 440 east. This anomaly is traceable through several

parallel survey lines, and its trace intersects a manhole located at the intersection of Lines 400

east and 20 south. Further, the depth of the anomaly is less than approximately 3 feet. There

is little doubt that the source of the anomaly is an underground utility. Anomaly B (Figures 2

and C-2) is characteristic of a metal object very near the ground surface. A similar anomaly

was caused by an iron manhole at the intersection of Lines 400 east and 20 south.

GPR surveys in the area north of monitoring well MW5-02 were apparently capable of

resolving underground utilities down to several inches in diameter. Therefore, assuming that

ammunition was containerized or buried in some other bulk fashion, it is likely its presence I

would be indicated in the GPR data to a depth of roughly 5 feet. The lack of unaccounted- 4

for GPR anomalies is an indication that large concentrations of ammunition are not present in

this location.

GPR profiles in the vicinity of Building 46, labelled GPR-1 through GPR-9 in Figure 1, were

compared with known surface and subsurface features. Anomalies traceable across several

records can be explained by the presence of features shown in Figure 2. For example,

comparison of Figures 2 and C-4 demonstrates the hyperbolic signature of several under-

ground utilities and the masking effect of the concrete-slab floor of Building 46.

No anomalies were found that strongly indicated the presence of buried ammunition near

Building 46. However, as shown in Figure C-4, geologic layering below a depth of approxi-

mately 2 feet is apparently indistinct to nonexistent. This leads to two possibilities: (1)

layering does not exist; this may be a natural condition or layering may be disturbed, (2)

layering exists but was not resolved with GPR due to poor penetration or interference from

known features. In considering the latter case, Figures C-l, C-2, and C-3 should be compared 0to Figure C-4. Figures C-1, C-2, and C-3 are radar profiles obtained along survey lines

located approximately 150 feet northeast of Building 46 (Figure 1). Geologic layering in this

area appears much more distinct than in the vicinity of Building 46; thereby lending support

to the former possibility.

5.0 Conclusions

Two phases of geophysical surveying were conducted at Sky Harbor IAP using GPR and EM

methods. The first phase of surveying involved geophysical clearance of drilling and SOV

locations of subsurface obstructions. In the second phase of the survey, subsurface conditions

were assessed for the presence of buried ammunition.

The geophysical clearance phase of work resulted in the successful installation of all borings,

monitoring wells, and SOV sample points.

The results and conclusions of the second phase of the investigation are based primarily on

GPR data. The EM data were of limited use because of the adverse effects of abundant

surface and subsurface electrically conducting material not related to previous disposal

operations.

Radar data in the vicinity of Building 46, the Liquid Oxygen Storage Area, did not provide 4

direct evidence of buried ammunition. However, the apparent lack of layering in geologic

materials within this area may be due to excavation and disruption during disposal operations.

Geologic layering appears more distinct in the survey area northwest of Building 46. This

may be an indication that disposal has not occurred in this area. Further, no anomalous

materials were apparent in the radar data to its approximately 5-foot depth limit, although

underground utilities were clearly resolved in this same interval. This implies that buried S

ammunition, if present and of approximately the dimensions of a typical underground utility

diameter, would be detected to a depth of approximately 5 feet.

Direct confirmation of the presence or absence of buried ammunition at Site 5 is not possible

based solely on nonintrusive methods. Individual cartridges smaller than the minimum

dimensions resolved by GPR may be present at any of the locations surveyed. Ammunition

in any form may be present at depths greater than effectively sensed by radar. Finally,

ammunition disposal occurring in discrete zones of dimensions smaller than the geophysical * 0grid spacing of 20 feet may not have been crossed by a geophysical survey line and therefore

could remain undetected.

APPENDIX A

THEORETICAL BACKGROUND

A. 1.0 Electromagnetic InductionElectromagnetic (EM) induction equipment used during this investigation consisted of a

Geonics EM-31DL terrain conductivity meter (EM-31) with an Omni digital data logger, a

Metrotech Model 810 pipe and cable detector (Metrotech), and a Radio Detection Model RD-

400 electromagnetic cable locator (RD-400).

The EM-31 has a transmitter and receiver coil mounted at each end of a 12-foot-long plastic

boom. An audio-frequency alternating current is applied to the transmitter coil, causing the

coil to radiate a primary EM field with a magnetic field vector parallel to the axis of the

coils. This time varying magnetic field induces eddy currents in any conducting material in

the subsurface as described by Faraday's Law on induction. These eddy currents have an

associated (secondary) magnetic field with a strength and phase shift relative to the primary

field that is dependent on the conductivity of the medium. The receiver coil measures the

resultant effect of both primary and secondary fields. By comparing the signal at the receiver

to that at the transmitter, the instrument is able to record the in-phase component (in-phase) 0

and the component 90 degrees out of phase (quadrature) with the primary field.

Most geological materials are poor conductors, and the flow of current through the material

takes place in the pore fluids (Keller and Frischknecht, 1966). Conductivity is predominantly

a function of soil type, porosity, permeability, pore fluid ion content, and degree of saturation.

The EM-31 is calibrated so that the out-of-phase component is converted to electrical

conductivity in units of millisiemens per meter (mS/m) (McNeill, 1980). The in-phase

component is read in parts per thousand (ppt) of the primary EM field and is generally

adjusted in the field to read zero response over background materials.

The depth of penetration for EM induction instruments is dependent on the transmitter-

receiver separation and coil orientation (McNeill, 1980). The EM-31 has an effective

exploration depth of about 18 feet when operating in the vertical dipole mode (horizontal

coils). In the absence of large metallic features such e, tanks, drums, pipes, and reinforced

concrete, the maximum instrument response results from materials at about 3 to 5 feet below

ground surface. A single buried drum typically can be located to depths of about 5 feet

whereas clusters of drums can be located to significantly greater depths depending on

KN/WP451 APP/08.26-91fORAFT #i A- 1A, S

background noise. The EM-31 generally must pass over or very near to a buried metallic

object to detect it. Both the out-of-phase (conductivity) and in-phase components exhibit a

characteristic anomaly over near-surface metallic conductors. This anomaly consists of anarrow zone having strong negative amplitude centered over the target and a broader lobe of

weaker, positive amplitude on either side of the target. For long, linear conductors such as

pipelines, the characteristic anomaly is as described above when the axis of the coils

(instrument boom) is at an angle to the conductor, however, when the instrument boom is

oriented parallel to the conductor, a positive amplitude anomaly is obtained.

EM-31 applications include the delineation of soil contamination, oil brine pits, buried

metallic and nonmetallic debris, landfill boundaries, buried pipes and cables, and buried

drums and tanks.

The RD-400 and Metrotech are specifically designed to accurately locate and delineate

underground pipes and utilities. A transmitter emits a radio-frequency signal that induces a

secondary EM field in nearby utilities. A receiver unit measures the signal strength of thissecondary field and emits an audible response to allow the precise location of the pipe, cable,

or other conductor in which a signal is induced. If the utility is accessible anywhere, the

source signal can be directly applied to it, making the secondary field much larger and readily 0measurable.

A.2.0 Ground Penetrating RadarGround penetrating radar (GPR) equipment used during this investigation consisted of a

Geophysical Survey Systems, Inc. (GSSI) Subsurface Interface Radar System 10 equippedwith 120-MHz, 300-MHz, and 500-MHz monostatic antennae.

In conducting a GPR survey, a transmitter antenna that emits a high frequency (center

frequencies in the range of 80 to 900 MHz) EM wave into the subsurface is pulled along the

survey line. This wave propagates at the speed of light in a vacuum scaled by the square root

of the relative dielectric constant of the medium and reflects at boundaries where the relative

dielectric constant (and therefore the propagation velocity) changes. The contrast in velocitybetween the two media can be quantified as a reflection coefficient at the boundary. The

magnitude of the reflection coefficient increases as the contrast in velocities increases, and its

sign is positive or negative depending on whether the velocity increases or decreases,

respectively, at the boundary.

I The reflected signal is detected at a receiver antenna, often as a characteristic triplet that is Ethe result of the receiving antenna response and multiples generated along the propagation X

I path. The signal is transmitted to a control unit, displayed on a color monitor, and saved on

digital tape (if necessary).

As predicted by Maxwell's equations for a propagating EM wave, two kinds of charge flow

J are caused by the alternating electric (E) and magnetic (H) fields associated with it (Ulriksen,

1982). These are conduction currents and displacement currents. The conduction current

term is predominant at lower frequencies and it is these that are used in the EM induction

method. At the higher frequencies used in the GPR method, the displacement current term

becomes predominant. The high frequencies will set bound charges in motion causing sj polarization.

The material physical properties that describe the movement of charges by conduction

currents and displacement currents are the conductivity and the dielectric constant of the

medium, respectively. The conductivity is a measure of the ease with which charges and

charged particles move freely through the medium when subjected to an external electric

field. The dielectric constant, or its value normalized by the dielectric constant of free space,called the relative dielectric constant, is a measure of how easily a medium polarizes to

accommodate the EM fields of propagating wave (Keller and Frischknecht, 1966).

Although conductivity has a lesser effect on the transmission of EM waves emitted from aGPR unit, it does have an important effect on the attenuation of the waves (Ulriksen, 1982).

Highly conductive media will attenuate the EM signal rapidly, restricting depth penetration of

the first several feet. Highly resistive (poorly conductive) media will allow much deeper

depth of penetration. The frequency of the transmitted waves also affects the depth of

penetration. Lower frequencies penetrate deeper, but have low resolution, whereas the higherfrequencies can resolve smaller objects and layers at the expense of decreased effective depth

penetration.

In unconsolidated materials, conduction takes place mostly through the pore fluids (Keller and

Frischknecht, 1966). Changes in pore fluid content, porosity, permeability, and degree of

saturation will therefore affect reflected and refracted EM signals. This is how trenches, in

which there may be different compaction relative to the surrounding area, can be identified.

When the target of a GPR survey is a metallic conductor such as metal pipes and cables,

drums, tanks, ammunition shells, etc., the mechanism is somewhat different. An EM wave

4,l

will completely reflect when reaching a metallic conductor. This total reflection makes

metallic targets well suited for the GPR method when they are within the depth of penetration U;

range of the instrument. There will be no reflections from below the metallic conductor,

although there generally will be multiples. The edges of the metallic reflector will have .

diffraction patterns that are a result of the fact that both the transmitting and the receiving

antennae are not focused, but emit and receive from a 45 degree cone. This cone allows the

radar to see objects that are ahead of it, placing them deeper in time. As the radar

approaches the object, the reflection becomes shallower, with the shallowest reflection taking

place when the radar is right above it. The same pattern will be seen as the antenna moves

away from the object.

Applications of GPR include delineation of pits and trenches containing metallic and

nonmetallic debris; location of buried pipes, drums, and tanks; mapping of landfill boundaries;

and mapping of near-surface geology. Near-surface metallic objects such as pipes and tanks

exhibit a characteristic high-amplitude hyperbolic anomaly and generally are relatively easy to

recognize.

EXECUTIVE SUMMARY

From January 15-17, 1991, TARGET Environmental Services, Inc.

(TARGET) conducted a soil gas survey at the Sky Harbor Air National 0

Guard Base and at the Papago Military Reservation, Phoenix,

Arizona, as part of a site investigation. Samples were analyzed

by GC/FID for petroleum hydrocarbons and by GC/ECD for chlorinated

hydrocarbons.

Very low levels of FID Total Volatiles occurred in several

locations in the JP-4 Hydrant Area and the Hazardous Waste Storage

Area at the Sky Harbor Air National Guard Base and at the Papago

Military Reservation. None of the standardized FID analytes were

present above their 1 gg/l detection limit in any of the areas at 0

either site.

GC/ECD analysis indicated that relatively low levels of 1,1-

dichloroethene (1,l-DCE) were present in samples collected from the

JP-4 Hydrant Area and the Hazardous Waste Storage Area at the Sky

Harbor Air National Guard Base. Tetrachloroethene (PCE) was

observed in all field samples. However, since comparable levels

were also observed in all Field Control Samples (indicating

persistent carryover in the sampling equipment), it is questionable

whether the concentrations present in the field samples accurately 5

reflect conditions in the soil gas at the sampling locations. None

of the other standardized halogenated hydrocarbons were present

above their respective detection limit in any soil gas samples from

either site.

Introduction

IT Corporation contracted Target Environmental Services, Inc.

(TARGET) to perform a soil gas survey at three locations on the Sky

Harbor National Guard Base and at one location on the Papago

Military Reservation, both in Phoenix, Arizona, as part of a site

4 investigation. The field and analytical phases of the work were

performed from January 15-17, 1991.

Field Procedures 9

Soil gas samples were collected at a total of 32 locations at

the three sites. Fourteen (14) samples were collected at Site 1

(JP-4 Hydrant Area), 11 with the hydraulic probe and 3 with the

drive rod. Twelve (12) samples were collected in Site 2 (Hazardous

Waste Storage Area), all using the hydraulic probe. Sampling was

attempted but was unsuccessful in three locations in Site 3 (Fuel

Bladder Area). Six (6) samples were collected at the hazardous

waste collection area on the Papago Military Reservation, all with

the drive rod. Sampling order is included in Table 1 and sampling 0

depths are shown in Table 2.

To collect samples with the van-mounted hydraulic probe, the

probe was used to advance connected 3' sections of i" diameter 0

Sthreaded steel casing down to the sampling depth. Although the

j proposed sampling depth was 10', some samples were collected at

shallower depths due to probe refusal. The entire sampling system 0

was purged with ambient air drawn through an organic vapor filter

cartridge. A teflon line was inserted into tne casing to the

bottom of the hole, and the bottom-hole line perforations were

I1-

3 isolated from the up-hole annulus by an inflatable packer.

To collect samples with the drive rod, a 1/2 inch hole was

produced to the sampling depth. Where pavement was present, an

electric hammer drill was employed for penetration prior to using

the drive rod. The entire sampling system was purged with ambient

air drawn through an organic vapor filter cartridge, and a stain-

less steel probe was inserted to the full depth of the hole and

sealed off from the atmosphere.

Whether using the hydraulic probe or the drive rod, a sample

of in-situ soil gas was then withdrawn through the probe and used

to purge atmospheric air from the sampling system. A second sample

of soil gas was withdrawn through the probe and encapsulated in a

pre-evacuated glass vial at two atmospheres of pressure (15 psig).

The self-sealing vial was detached from the sampling system,

packaged, labeled, and transported to the laboratory for analysis.

Prior to the day's fielQ activities all sampling equipment,

drive rods, and probes were decontaminated by washing with soapy

water and rinsing thoroughly. Internal surfaces were flushed dry

using pre-purified nitrogen, and external surfaces were wiped clean

using clean paper towels.

* Field control samples were collected at the beginning and end

of each day's field activities and after finishing a day's sampling

in an area. These QA/QC samples were obtained by inserting the

4 probe tip into a tube flushed by a 20 psi flow of pre-purified

nitrogen and collecting in the same manner as described above.

Laboratory Procedures

All of the samples collected during the field phase of the

survey were subjected to dual analyses in the field in TARGET's

climate-controlled mobile laboratory using a Shimadzu 14-A gas

chromatograph.

The first analysis was conducted according to EPA Method 601

(modified) on a gas chromatograph equipped with an electron capture

detector (ECD), but using direct injection instead of purge and

trap. Specific analytes standardized for this analysis were:

1,1-dichloroethene (1,1-DCE)1,1,1-trichloroethane (1,1,1-TCA)tetrachloroethene (PCE)

Ten other halogenated hydrocarbons are also included in

TARGET's standard gas mixture and are standardized in every

analytical batch. These compounds (and their respective detection

limits, in ag/l) are trichlorofluoromethane (0.05), methylene

chloride (1.0), trans-1,2-dichloroethene (1.0), 1,1-dichloroethane

(1.0), cis-l,2-dichloroethene (1.0), chloroform (0.10), carbon

tetrachloride (0.05), trichloroethene (0.10), 1,1,2-trichloroethane

(0.10), and 1,1,2,2-tetrachloroethane (0.1).

The second analysis was conducted according to EPA Method 602

(modified) on a gas chromatograph equipped with a flame ionization

detector (FID), but using direct injection instead of purge and

trap. The analytes selected for standardization in this analysis

were:

benzenetolueneethylbenzenemeta- and para- xyleneortho-xylene

3

-

II i - - . . . . . . . . . . . . . .

3 These compounds were chosen because of their utility in evaluating

the presence of fuel products, or petroleum based solvents.

4 The FID Total Volatiles values were generated by summing the

areas of all chromatogram peaks and calculated using the instrument

response factor for toluene. Injection peaks, which also contain

the light hydrocarbon methane, were excluded to avoid the skewing

of the Total Volatiles (Totals) values due to injection distur-

bances and biogenic methane. For samples with low hydrocarbon

concentrations, the calculated Total Volatiles concentration is S

occasionally lower than the sum of the individual analytes. This

is because the response factor used for the Total Volatiles calcu-

lation is a constant, whereas the individual analyte response fac-

tors vary with concentration. It is important to understand that

the Total Volatiles levels reported are relative, not absolute,

values.

The analytical equipment was calibrated using an instrument-

response curve and injection of known concentrations of the above

4 standards. Retention times of the standards were used to identify

the peaks in the chromatograms of the field samples and their

response factors were used to calculate the analyte concentrations.

4 The tabulated results of the laboratory analyses of the soil gas

samples are reported .4 microgrars per liter (gg/l) in Tables 3

through 5. Although "micrograms per liter" is equivalent to "parts

4 per billion (v/v)'"1 in water analyses, they are not equivalent in

gas analyses, due to the difference in the mass of equal volumes

of water and gas matrices.

4 For QA/QC purposes, a duplicate analysis was performed on

4

I

4 ! 0 i 0i

lb

3 every tenth field sample. Laboratory blanks of nitrogen gas

(99.999%) were also analyzed after every tenth field sample.

quality Assurance Samples

All laboratory blanks were free of detectable levels of the

standardized analytes.

All Field Control Samples contained tetrachloroethene (PCE)

ranging from 0.08 to 4.0 gg/l, indicating persistent carryover in

the sampling equipment. The PCE observed in the field samples

(0.60 to 6.7 gg/l) may not accurately reflect conditions in the

soil gas at the sampling locations. Unsuccessful attempts were

made to remove the contamination from the sampling equipment.

Instead of immediately outflushing the nitrogen drawn into the

sampling system during the purging step, the nitrogen was allowed

to set in the sampling box for 5 minutes prior to flushing. In

addition, sampling boxes were evacuated for 1/2 hour at the end of

each day.

Analyte concentrations in duplicate sample pairs were within

acceptable limits.
