1.0 Introduction1.1 Background

The Geneva Industries Superfund site is a 13-acre tract located at 9334 Canniff Road inHouston, Texas. The site is j u s t east of Interstate Highway 45 (Gulf Freeway), north ofAirport Boulevard/College Stree t , and about a mile east of Hobby Airport.This site is an abandoned refinery that manufactured chemicals such as biphenyls,polychlorinated biphenyls (PCB), phenyl phenol, naphtha and numbers 2 and 6 fuel oils. Asof 1981, the 13-acre site and adjo ining property to the south contained processing tanks andpip ing , a large wastewater lagoon, two smaller lagoons, a closed lagoon containing solidPCB wastes, a diked tank area, several drum storage areas, a landfill, and a possiblelandfarm. As a result of past practices at the site, extensive soil and shallow groundwatercontamination had occurred.In May of 1983, Resource Engineering, Inc. (REI), presented the Texas Department ofWater Resources, now known as the Texas Water Commission (TWC), and The U.S."Environmental Protection Agency (EPA) with f i n d i n g s from an investigation of the sitehistory and a preliminary field investigation. Since the discovery of the initial contamination,actions involving removal and disposal of PCB contaminated soil, wastewater lagoon sludge,wastewater, and drained wastes have been completed.Investigations which have been performed at the site include the fo l lowing: SiteInvestigation, Feas i b i l i ty Study, and Fault Investigation. As part of these investigations 15monitor wells and 8 piezometers were installed to evaluate groundwater contamination in the30-foot and 100-foot sands.

In September 1986, EPA selected the f inal remedy from alternatives put f or th in theFeasibi l i ty S t u d y and issued a Record of Decision (ROD). The major components of theselected remedy are as fo l lows:

1. Remove and dispose of surface structures in an off site hazardous wastel a n d f i l l2. Excavate soils contaminated with more than 100 ppm of polychlorinatedbiphenyls and all buried drums on site3. Dispose of excavated soils and drums at an EPA-approved o f f - s i t e disposalf a c i l i t y4. Construct a multi-layer surface cap over the site and a slurry wall around theperimeter of the site, tied into the clay below the 30-foot sand5. Recover trichloroethylene (TCE) contaminated groundwater from the 30 and100-foot sand, treat on site by carbon adsorption, and discharge treatede f f l u e n t into the adjacent f l o od control channel.

The f i r s t four components of the ROD have been completed as part of the source controlremedial action. T h i s Design Concept Memorandum (DCM) is developed to sp e c i f i ca l lyaddress the groundwater remediation.

1.2 Purpose of Design Concept MemorandumIn May 1991, the Texas Water Commission retained IT Corporation (hereafter The Engineer)to proceed with the f inal groundwater remedial design for the Geneva Industries Site.

2.0 Design Objectives and ApproachThe final product for this design phase will be a set of plans and performance specificationsthat will constitute bid and contract documents for the Remedial Action Phase of the projec t .The design will include the technical requirements necessary to achieve the objectives of theROD. Plans and speci f ications will be developed for equipment and support fac i l i t i e s torecover contaminated groundwater from the 30-foot and 100-foot sands. The groundwaterrecovery system will be designed in a manner that e f f i c i e n t l y recovers groundwater and doesnot disturb the slurry wall and RCRA cap containment structure that has been installed at thesite.The groundwater recovery system will be coupled with a groundwater treatment systemdesigned to remove pol lu tant s and discharge an e f f l u e n t that complies with applicableNational Pollutant Discharge Elimination System (NPDES) and the TWC limitations.

Existing analytical data will be utilized wherever possible. Any deficiencies in the data willbe ident i f i ed and documented. New analytical information will be developed wherenecessary or assumptions will be made and documented. Design calculations and the basisfor the design will be submitted with all plans and specifications.

2.1 Description and Flow of Design2.1.1 Groundwater RecoveryThe Engineer will review the design for the shallow and deep recovery wells and the wellsin the pressure relief system. Thi s review will i d e n t i f y data gaps as they may relate togeological data, monitor well locations, and contaminant concentration levels. In addition,a review of the groundwater recovery concept will be conducted to evaluate the potential forsite subsidence related to the groundwater recovery operation. Computer modeling ofavailable hydrogeological data will be used to evaluate the e f f e c t s of pumping per therecovery concept and design.

HO\8-91\TWCV421486\DCM.RV1

The Engineer will develop the speci f ications for the construction and installation of therecovery wells and the wells in the pressure relief system. These specifications will includedri l l ing methods, cementing and grouting, details of well placement, equipment installation,and well development. As part of this work, the Engineer will also i d e n t i f y the maps andgeological analyses that should be updated based on the data generated by the well dri l l ing.

The Engineer will update their records to appropriate ly reflection conditions af t er theinstallation and start-up of proposed of two new monitoring wells in the 100-foot sand, andas part of construction oversight.2.1.2 Groundwater TreatmentThe Engineer will prepare the equipment site layout, which will include plans and drawingsfor the installation and erection of the groundwater treatment plant bui lding, carbonabsorption, pretreatment, utilities, access and entrance roads, parking areas, site security,landscaping, t r a f f i c f l o w and control, temporary and permanent fac i l i t i e s , groundwaterrecovery and treatment systems. Design factors will be used to prepare performancespeci f ications including required pumping rates and discharge quantities. The performancespecif ications for the Waste Water Treatment plant will be in conformance with the dischargerequirements speci f ied in the ROD.

The construction drawings will be generated by a computer-aided design (CAD) system.T h i s method will permit the rapid preparation of the drawings for review of the plandrawings. Drawings will generally be the standard construction size of 24" by 36". Thepreparation of the plans using CAD will also fa c i l i ta t e the generation of 8-1/2" by 11" or11" by 17" size drawings for easier review, as required. Six copies of each design submittalwill be produced.

3.0 Groundwater RecoveryRecovery of contaminated groundwater in the vicinity of MW-5 in the 30-foot sand and inMW-9 in the 100-foot sand was deemed the best alternative by the ROD. Thi s alternativeprovides a su f f i c i en t level of protection to potential users of the 100-foot sand. The primarycontaminant of concern regarding the 100-foot sand is trichloroethylene (TCE). Recoveryof TCE from both sands would minimize the threat of further contamination to the 100-footsand and potential exposure to current or future human receptors.

Pumping of groundwater is anticipated for ten years or less. Depending on the amount ofcontamination found in the 100-foot sand, the pumping of this groundwater may becompleted within two years. The volume of water in the 30-foot sand is estimated to be1.4 x 10* gallons. Hydrogeological calculations predict that it will take up to ten years toremove this groundwater.

3.1 Status of WellsThe ROD spec i f i ed that existing monitor wells and piezometers that were not included in thegroundwater monitoring system would be plugged prior to implementing major constructionactivities on site. T h i s was necessary to eliminate any potential vertical migration pathwaysthrough the 30-foot and 100-foot sand. It may be necessary to install additional monitorwells for both the 30-foot sand and 100-foot sand to adequately evaluate the recovery systeme f f e c t ivene s s and assure that TCE migration is not occurring in the 100-foot sand.

According to the latest information the f o l l o w i n g monitor wells are still in place and readyto be used for sampling and monitoring outside the slurry wall containment.

The initial phase of the groundwater recovery design will be to veri fy the status of thesewells and confirm the status of the f iv e recovery well casings for the 30-foot sand and therecovery well casing for the 100-foot sand.

Inside the containment structure there is a cluster of four monitoring wells. The casings arein place for f ive recovery wells in the 30-foot sand and one in the 100-foot sand.3.2 Estimated Water Flow RatesA preliminary evaluation has been performed to assess the pumping rates to be expectedfrom the groundwater recovery operation in the 30-foot and 100-foot sands.

Well casings (risers) were placed during the construction of the clay cap. The purpose ofthese reisers was to assure the integrity of the cap by eliminating the need to drill throughthe cap and associated geosynthetic liners. The location of the casings of the recovery wellsat the site is shown in Figure 2. Well numbers 1, 2, 3, 4, and 5 are expected to withdrawthe groundwater from the 30-foot sand. Well No. 6 is expected to recover the groundwaterfrom the 100-foot sand. In addition, risers for the pressure relief wells have been l e f t inplace. Originally these pressure relief wells were designed to pump the water that couldin f i l t ra t e in the top unit through the clay cap and associated synthetic liners.

The pumping would also provide a means of maintaining a lower hydraulic head pressurefor the water inside the slurry wall. Any f l o w through the slurry wall would therefore beinward and contain contaminants.3.2.2 Preliminary Analysis and ResultsThe approximate elevations of the top and bottom layers of both the 30-foot and 100-footlayers have been determined from contour maps. The thickness of each layer was foundusing the Regional Variable Theory better known as the Kriging method. Using this methodand the hydrogeologic properties of the units, the respective volume of groundwater in eachlayer was calculated. The volume of water in the 30-foot sand is estimated to be 1.4 mill iongallons and the volume of water in the 100-foot sand is estimated to be 3.16 million gallonswithin the boundaries of the slurry wall.

The extent of the contamination in the 100-foot sand is not known. It is proposed to drillat least two additional monitoring well s to the lower unit to determine the extent and.concentration of the contamination. Also during the execution of this drill ing it will bepossible to determine some hydrogeological parameters such as l i thology of the unit,thickness, grain size distribution of the 100-foot sand, horizontal hydraulic conductivity ofthe sand, and vertical hydraulic conductivity of the interlaying clay between the 30-foot andthe 100-foot sand. The proposed new two wells could be located near the fence outside thewest side and east side of the slurry wall containment.The Piezometric heads and drawdowns simulations were performed using a computer model.The code used was the three Dimensional F i n i t e Di f f e r enc e Model of the U . S . GeologicalSurvey ( M O D F L O W ) . In addition to the computer model, analytical calculations for heads

HO\8-91\TWCV421486\DCM.RV1 11

005536

and drawdowns were performed using the Cooper-Jacob approximation of the Theis solution.An analytical solution for calculation the piezometric heads in the 30-foot sand because ofthe presence of the slurry wall, which is considered as an impermeable boundary, requiresthe use of the Image Method. The Image Method means that for each real well an imagewell at a symmetric distance from the real one must be placed. There fore to study the e f f e c tof a recovery well, we need to place eight image wells around the one to be analyzed. Forthe f ive recovery wells we need to study a total of 40 image wells. As a f ir s t approximationwe have analyzed the e f f e c t of one well and determined the corresponding drawdown SO ftfrom the well. Both methods agreed that at a pumping rate of 0.5 gallons per minute, as itwas speci f ied in the reports mentioned above, the 30-foot sand becomes dry at a distance ofSO feet from the well in a period of approximately 6 months. Variations in f l o w ratesproduced better results because the drawdowns were reduced. For the 100-foot sand thespec i f i ed pumping rate of 10 gpm seems to be adequate.

3.2.3 ConclusionsUpon consideration of the analysis per formed, we propose to examine alternative methodsto withdraw water from the 30-foot sand. These alternatives would include:

• S t u d y of a model with intermittent pumping at adequate rates• S t u d y of a model with continuous pumping and low pressure injection into theupper unit• S t u d y of a model with intermittent pumping and low pressure injection into the

upper unit.

The aquifer in question requires a unique pumping scheme so as not to dry the wells in ashort period of time and before the contaminated groundwater in the upper unit has beenwithdrawn. The modeling process will determine a more e f f i c i e n t method for pumping thegroundwater from both units.

HO\8-91\TWCV4214S6\DCM.RV1 12

4.0 Groundwater Treatment SystemSeveral methods of remediation were evaluated for the ROD. The alternative plans wereevaluated using the f o l l ow ing criteria: cost, acceptable engineering practices, andef fect iveness . A fai lure in either the acceptable engineering practices, or e f f e c t ivenes scategories excluded an alternative f rom further consideration.

Four options for contaminated water cleanup were evaluated in the ROD:

• Option 1 was eliminated because it only cleaned up contamination within the slurrywall and had no e f f e c t on the 100-foot sand, a documented water s u p p l y zone.

• Option 2 provides adequate cleanup of both the 30-foot and 100-foot sands at a costthat is j u s t s l i g h t l y higher than that for Option 1.

• Option 3 was eliminate because the net present worth was considerably greater thanthe costs of Options 1 or 2, and didn't provide any greater health and environmentalbenefits.

• Option 4, the "No Action" option was dismissed because eventual weathering of theslurry cap could lead to contaminant release and the 100-foot sand would remaincontaminated.

Option 2 consists of a pump and treatment system using activated carbon to absorb thecontaminant. A treatabili ty test performed on water from MW-5 in the 30-foot sand aquiferconcluded that 0.65 pounds of carbon would be required to treat 1,000 gallons ofcontaminated groundwater, which makes it a more cost e f f e c t i v e system than bioremediationat this stage. The DCM f o l l o w s Option 2 which was the preferred alternative in the ROD.

A preliminary design of the groundwater treatment unit is provided in the DCM and will berefined in subsequent design submittal. The hydrogeological information developed persection 3.2 of this package will be used to develop a mass balance for the treatment unit.Concentrations of contaminants throughout the treatment unit will be estimated from raw

HO\g-91\TWCV4214M\DCM.RVl 13

005538

groundwater data taken from the remedial investigation phase and data from previouslycompleted carbon adsorption tests. The above data is available in reports referenced inTable 2 of this package. More recent analytical data showing the actual concentration ofcontaminants is desirable.

4.1 Design CriteriaThe groundwater treatments system will be discharging an e f f l u e n t that meets applicablerelevant and appropriate regulations. The f o l l o w i n g regulations have control limits forpol lutant s at the site.

• Surfac e Water Quality Standards , Texas Administrative Code, Title 31, 307• EPA E f f l u e n t Guidelines and Standards for Organic Chemicals, 40 CFR 414

Regulations for Texas Surfac e Water Quality (TWQ) Standards provide numerical limits for30 pollutants . Total PCB's have an acute fresh water limit of 2.0 ppb. Section 307.6provides that this limit be considered with the Practical Quantification Levels (PQL) forpol lutant s and other site spec i f i c information.The treatment system will be design to collect solvent phase PCB's in the oil water separatorfor subsequent disposal. PCB's that may be soluble in the water phase will be removed byactivated carbon and deliver an e f f l u e n t with PCB's less the 2.0 ppb. An e f f l u e n t with nodetectable PCB's is expected. The minimum detection limit (MDL) will be established bythe laboratory with the spec i f i c matrix in the groundwater.

The TWQ standards do not have limits for trichloroethylene, however the limits in 40 CFR414, which were designed to regulate discharges from the Organic Chemical, Plastics, andSynthet i c Fibers (OCPSF) industries will be used as the design basis.

Appl i cab l e l imits for trichloroethylene are presented in Subpart I: Direct discharge pointsources that use end-of-pipe biological treatment.The daily maximum and monthly average concentration limits for TCE are 69 ppb and 26p p b , respectively. We will design the unit to discharge an e f f l u e n t with less than 10 ppb

HO\8-91\TWC\4214»6\DCM.RV1 14

005539

TCE. It is anticipated that the MDL will be S ppb. Under normal operation there shouldbe no detectable TCE in the e f f l u e n t .

4.2 Process DescriptionThe process f l o w diagram is presented in Figure 3. The f o l l ow ing paragraphs present adescription of the principal equipment and the general design of the system.The proposed groundwater treatment system will have an oil/water separator. Thi s will beinstalled at the front of the process. The main purpose of the separator will be to removeoil contaminants that could reduce the useful l i f e of the granular activated carbon in theadsorbers. The separator will also serve as a pump tank to better equalize f l o w to theadsorbers.

The recommended design has f i l t e r s before the activated carbon adsorbers. F i l t e r s willminimize the amount of solids that reach the adsorbers and thereby reduce the frequency thatthe adsorbers will need to be backwashed! Reduced backwashing will lower operatormaintenance and reduce downtime for the system. A final f i l t e r is provided to removecarbon particles that may be in the e f f l u e n t f rom the adsorbers. The discharge samplingpoint will be located af t er the final f i l t er s .Downflow rather than u p f l o w adsorbers are recommended because fines in f i l t ra t ion will beminimized and any suspended particles that adhere to the carbon particles can be easilybackwashed. A less complicated in f lu en t distribution system is also present in this design.

The proposed treatment system design has carbon adsorbers that are normally operated inseries. Piping will be provided to operate the adsorbers in parallel if that mode of operationbecomes desirable. The advantages of operating the adsorbers in series is that the relativelylow design f l o w rate of 10 to IS gpm is more readily distributed when the f u l l f l o w isdirected to one adsorber. Operating in series also provides a more reliable e f f l u e n t quality.The e f f l u e n t f rom the f ir s t adsorber will be periodically analyzed to confirm thatbreakthrough by groundwater contaminants has not occurred. T h i s will assure that thee f f l u e n t from the second adsorber complies with appl i cab l e water quality standards. Thee f f l u e n t from the second adsorber also will be periodical ly sampled before discharge into theHarris County Flood Control district channel.

I Section 319.5 of the Texas Administrative Code provides requirements for sampling locationsand frequency of analysis and measurements for industrial dischargers. The discharge fromr~ the Geneva groundwater treatment will be consistent with fac i l i t i e s sized at 0 to 0.05 MGD.Therefore pol lu tant sampling will be analyzed at least once per week. F l o w will be

r~ measured once per day. A f l o w totalizer will be provided to measure f l o w on a continualbasis.

5.0 Groundwater MonitoringA groundwater monitoring system will be developed during the design phase. The objectivewill be to provide accurate analytical information about the recovery of TCE from the 30-foot and 100-foot sand. Consistent with the ROD the monitoring system will be designedto achieve the f o l l o w i n g objectives.

• Confirm that groundwater remediation is complying with the post-closurerequirements of RCRA• Monitor recovery of TCE from both sands to minimize the threat for furthercontamination to the 100-foot sand• Minimize the amount of water pumped through the recovery system by s topping

the recovery from the 100- foot sand when monitoring shows that it isappropriate.

The design of the groundwater monitoring system incorporates guidelines presented inSubpart F, 40 CFR 265 Groundwater Monitoring, EPA Interim Sta tu s Standards for Ownersand Operators of Hazardous Waste Facil i t i e s . The regulation provides standards for locatingand installing wells that provide representative groundwater.TCE was the pol lu tant of concern because of its potential to migrate to the 100-foot sand.The recovery of TCE from both sands will be monitored. When TCE in the 100-foot sandis at or below background standards the recovery of groundwater from the 100-foot sandmay be terminated. By s topping the treatment of this groundwater operating system, the costfor the recovery system will be reduced.

A preliminary monitoring strategy will be to use existing wells inside and outside the slurrywall containment. We anticipate that the f our wells outside the slurry wall could be used toevaluate the performance of the containment structure. These wells could be used to:

• Take samples from MW-10 and MW-11 to veri fy that the slurry wall hascontained the contaminated groundwater as designed• Take samples from MW-22 and MW-23 to determine contamination in thedeeper bearing unit.

Inside the containment structure there are four monitoring wells in the 30-foot sand.Figure 2 shows the locations of existing and proposed wells. Additional data oncontamination in the 30-foot sand may be obtained by analyzing the groundwater recoveredfrom the 30-foot sand. Analysi s of the groundwater recovered from the 100-foot sand viaRW-6 should provide s u f f i c i e n t monitoring information when it is compared to the samplesfrom MW-22 and MW-23 outside the containment. This comparison should be performedaf t er the groundwater treatment system has been temporarily shut-down, and the aquifer hasbeen allowed to recover to equilibrium. T h i s sampling should be performed every sixmonths to track the progress of the groundwater recovery.

6.0 Potent/a/ Problems6.1 Groundwater TreatmentThe design of the activated carbon treatment system must currently be developed usinganalytical data that were taken in 1987 for contaminants of concern. Append ix A presentsanalytical results from sampling of wells MW-5 and MW-9 in 1987. Table 5 of this packagepresents a summary of the analytical results of wells in the 100-foot sand. More recent dataare desirable to provide more accurate understanding of the contaminate load that will bepumped into the activated carbon adsorbers. New information will also assist the Engineerin developing accurate hydrogeological modeling of contaminants.Sampl ing of monitor wells and GC/MS analysis of the samples for volatile and baseneutral/acid extractable organics is not provided for in the scope of work. The Engineerrecommends that this work be accomplished to fa c i l i t a t e design and subsequent remedialaction.

7.0 Preliminary Cost EstimateThe f o l l owing cost estimate was developed from the preliminary design. It is anticipated thatrevisions to this estimate will be necessary as the design for plans and specif icationsprogress. The cost presented are capital cost and where speci f ied the installation cost. Thecosts that bidders will incur in procuring equipment, completing there detail designs andinstall ing the equipment are not included.

The Drilling Contractor must be class i f ied as the Generator of the Waste and will beresponsible for disposal of the well spoil. The material must be analyzed for PCB's andT C E . Disposal cost will be by incineration if PCB regulatory limits are exceeded. Thematerial will otherwise be l a n d f i l l e d . The cost is not included. The dri l l ing work will beclassi f ied as level "C".

A 70,000 capital cost item is listed for a f i e l d gas chromatograph and supporting equipment.Field and analytical monitoring will allow the e f f l u e n t to be discharged directly from thecarbon adsorbers to the drainage ditch. The alternative is to contain the treated e f f l u e n t andrelease af t er analytical results are performed by an o f f - s i t e laboratory. A cost comparisonof these alternatives is being developed for the 30 percent design.

8.0 Ancillary IssuesA design checklist will be submitted with the 30 percent design plans and specifications. Al i s t ing of proposed plan sheets and technical speci f icat ions will also be submitted at thatphase of the projec t .The Final Design will include updated cost and schedule projec t ions , access to the site,permit requirements, quality control, health and sa f e ty , community relation issues, and O&Mof the site a f t er installation of the remedial action faci l i t ie s .

8.1 Decontamination of EquipmentThe groundwater treatment system will be designed to minimize and contain any spi l l s .Preliminary plans include a bui lding and appropriate diking. T h i s should eliminate the needto treat po t ent ia l ly contaminated stormwater and also provide containment for sp i l l s .

Procedures will be developed to properly handle spent activated carbon to eliminate o f f - s i t ereleases when removing and replenishing carbon. Procedures will also be developed todecontaminate equipment before demobilization.8.2 Site SecurityS i t e security protocols, in writing, will be required to handle breaches in security in aconsistent predetermined manner. The protocols should be consistent with e f f e c t i v eprocedures already employed at the site.The admittance of all persons and vehicles onto the site will be strictly controlled. Eachperson requesting entrance on site will be required to present proper identif ication.Detailed descriptions of proper actions to take care of an emergency situation will beprovided. Telephone numbers will be posted to obtain assistance and n o t i f y the appropriateagencies.
