Dear Mr. Novick:
The accompanying report, Soil Sampling Operations - Burns Hill Road - Hudson, New Hampshire, is submitted to document that the requirements of Technical Direction Document No. 01-8603-17 have been met. The major element of the TDD was the preparation of a sampling grid from which the TAT could accurately obtain soil samples. A grid map of the sampled area is included in the appendix of this report. Using that layout, the TATs collected 39 soil samples from the site. The samples were submitted to NERL for analysis.
If there are any questions, I can be reached at (617) 229-A O A ' '
April 28, 1986

7• Polychlorinated Biphenyl (PCB) - 1248
One of several aromatic compunds containing two nuclei with two or more substituent chlorine atoms, colorless liquids that are highly toxic and are carcinogens. It's PEL is 1 mg/m3 and it's IDLH is 10 mg/m3’
Health Hazards
PCB's have two distinct actions on the body, namely, a skin effect and a—toxic—action on the liver. The lesion produced in the liver is an acute yellow atrophy. This toxic action is increased if there is exposure to carbon tetrachloride at the same time. In persons who have suffered systematic intoxication, the usual signs and symptoms are nausea, vomiting, loss of weight, jaundice, edema and abdominal pain. Where the liver damage has been severe the patient may pass into a coma and die.
8. Styrene C6H5CH=CH2

D. INTRODUCTION & SITE BACKGROUND
On September II, 1985, Roberta Pirie and Jan Patterson, from the State of New Hampshire Bureau of Hazardous Waste compliance and Enforcement; Division of Public Health Services (NHDPHS) investigated a complaint, by Bob and Denise Mathews, regarding the discovery of several 55-gallon drums located on private property at 52 Burns Hill Road in Hudson, NH.
The property has been owned by Denise Mathew's father, Mr Roqer Guerette, since 1949. From 1950-1956. Mr. Guerette mowed the field each year for hay. After 1956, several junkyard dealers used the site as a disposal area for various forms of industrial and solid wastes, including several 55-gallon drums. Because these oisposal practices went relatively unmanaged, verv little information is avaiiable regarding the generator(s) of the drums, although it is suspected that Mr. R. Pelanger, who owns an autorepair and junkyard business, rented this property for several years.
On August 7, 1985, Bob Mathews who lives adjacent to the site, contracted a bulldozer to clear the site and transfer the tires to the landfill. During this clean-up operation, the equipment operator noticed several 55-gallon dru.ms among the tires and other miscellaneous debris. As he began to move these drums, S^VSna^ began leaking an unknown liquid material with a "strong odor". At that point, Mr. Mathews stopped all site activity and contacted the NHDPHS. This complaint prompted the state to conduct an initial site investigation on September 11, 1985.
2?t0b6r i1, }985' Pa™ Sprague and Kevin Hopkins, from the NHDPHS, conducted a technical hazardous waste site assessment at the Burns Hill Road Site, which was a follow-up to the initial complaint inspection of September 11, 1985.
The site is approximately 2 acres and is classified nostly as rural and wooded. The site is bordered by Bob Mathew's property o the northwest, the old Hudson Dunp to the east, and Burns Hill
Road to the southwest. During the NHDPHS investigation, it was learned that in addition to the tires and other debris, the site also contained 14 - 55 gallon drums and 22 partially full drums of hazardous waste solvents. Several of the drums wer- also analyzed for pesticide and PCB contamination, and showed either low or undetectable levels.
Following this investigation, the NHDPHS classified the site as
a top priority for drum removal and further remedial investigation".

3. General Safety Rules And Equipment
a. Do not wark alone when performing tasks in areas that require protective clothing unless the work will be of short duration and another person has been informed of your location, or while performing any task that could be potentially incapacitating.
b. There will be no eating, drinking, or smoking in either the Exclusion Zone or the Contamination Reduction Zone.
c. All personnel must pass through the Contamination Reduction Zone to enter the Exclusion Zone.
d. An emergency deluge shower/spray can is to be located on the Decontamination truck.
e. Where practical, all too Is/equip .rent will be spark proof, explosion resistant and/or bonded and grounded.
f. Fire extinguishers will be on site.
17
g. Since site evacuation may be necessary if an explosion,fire, or the like occurs on site, an individual shall be assigned to sound a horn. The evacuation signal will betwo long blasts every iO seconds until all -ersonnel are evaluated and account 'd for. This proced re will be reviewed at each mornin.’s safety meeting (i scribed in H 4 , . elow) .
h. A :irst-aid kit will ,\e on scene at all times during operational hours.
i. The location of all emergency equipment on rite will be within the Decontaminat: n truck.
j. No parking of non-esse: r ial vehicles inside of the work are will be permitt . since safety la _s may be obs* acted.
k. No -ork will be perfor red in the Exclusion one during hour- of darkness.
4. Morning afety Meetings
A morni g safety meeting wi .1 be conducted each ray for all site personnel. Daily atte; lance sheets will be maintained. The sarety procedures, vacuation procedur s, escape procedures, and the day's planned operation. will be discussed during these meetings.
5. Site Control
Site access must be controlled to eliminate risk of.spreading contaminants and to protect the public. The perimeter of the site will be cordoned off with barrier tape and appropriate warning signs will be posted. Uniformed security service will be provided during all non-work hours. Except in an emergency, all personnel shall enter and exit through the Contamination Reduction Zone.
6. Designation of Work Zones at the Site
The entire site will be divided into three zones:
a. The Exclusion Zone (EZ) which is known to be or have a potential for becoming contaminated;
b. The Contamination Reduction Zone (CRZ) where decontamination of personnel and equipment exiting the Exclusion Zone will be performed.
18
The Clean Zone (CZ) which is not contaminated;c.
As work progresses on site, the OSC may determine that an area previously designated an EZ is no longer so classified. Such a change, however, is not intended to change the desingation of the CRZ since this may involve movement of the decontamination facilities, andconsequently, increase costs.
d. Specific layout of these zones:
1. The Exclusion Zone (EZ) is that portion of the site where drums are present or excavation of drums is occurring which includes the drum staging area.
2. The Contamination Reduction Zone (CRZ) will bestratigically located just before the actual removal action begins. It's location shall take into consideration site characteristics such as wind direction, points of access from rroin roads, access agreements by local residents and site spaceconstraints.
j. The Clean Zone (CZ) will include all those areas outside the Contamination Reduction Zone and the Exclusion Zone until such time during the removal action as these 2 zones are declared clean by the OSC.
4. The location of these zones are illustrated on the site map (see Figure 1 - Section L).
7. Personnel Protection
Personnel protective equipment and safety requirements must be appropriate to protect against the known or worst potential hazards on the site. Protective equipment should be selected based on the concentrations and possible routes of personnel exposure to known or potential worst case substances.
The appropriate level of protection shall be determined prior to the initial entry on site based on the best available information. Subsequent information may result in changing the original level selected.
Level C protection has been selected as the entry level of protection into the EZ as dictated by routine air monitoring. Level B protection shall be worn when organic contaminants exceed 5 ppm above background. Level B protection shall be worn at all times when work operations involve the handling of drums; excavation, staging, sampling, and overpacking.

I. DECONTAMINATION PROTOCOL
Decontamination Protocol will involve the thorough decontamination of all equipment and personnel leaving the EZ and
CRZ areas. The following decontamination procedures will be followed at the Burns Hill Road Site. Changes in tnese procedures may be made by the OSC to accommodate changing site operations.
Personnel are responsible for decontamination (and routine maintenance) of their individual face masks. They will be decontaminated at the end of each day, using the following procedure, at a minimum.
Wash in a detergent solution, such as lysol in water. Rinse with water and hang to dry.
1. Complete Procedure
The Decontamination Protocol will ba a six (6) stage process, which will be strictly adhered to by all personnel entering the EZ, or areas of the site deemed by the OSC or Safety Officer to contain hazardous vapor concentrations.

K- EFFECTS OF COLD EXPOSURE
Persons working outdoors in temperatures at or below freezing may e rostbitten. Extreme cold for a short time may cause severe
injury to exppsed body surfaces, or result in profound generalized cooling, causing death. Areas of the body which have high surface area-to-volume ratio such as fingers, toes, and ears, are the most susceptible.
Two factors influence the development of a cold injury: ambienttemperature and the velocity of the wind. wind chill is used to escribe the chilling effect of moving air in combination with low temperature. For instance, 10 degrees Fahrenheit with a wind ot 10 miles per hour (nph) is equivalent in chilling effect to still air at -18 degrees Fahrenheit.
27
As a general rule, the greatest incremental increase in wind chill occurs wtien a wind of 5 nph increases to 10 nph. Additionally, water conducts heat 240 times faster than air. Th ;s, the body -ools suddenly when rhemical -protect ive 'guioment is removed if th- clothing undernea* is perspiration sr -dced".
Lo'al injury re siting from cold is. included in the gen ric term fi .stbite. The. e are several degrees of damage. Frostbite of th. extremities < an be categorized ir.to:
Frost nip or incipient frostbite: Characterized by suddenlyblanching or whitening of skin.
Superficial :rostbite; Skin has a waxy or white a: oearance and is firm • ' the touch, but ti sue beneath is resident.
Deep frostbit •>: Tissues are col-:, pale, and solid; • >;tremelyserious in jur . .
Systemic hypother:-.ia is caused by exposure to freezing or rapidly dropping temperature. Its symptoms -re usually exhibited in five sta.es: 1) shiv ring, 2) apathy, ostlessness, sleepirss, and(sc-etimes) rapi-; cooling of the body to less than 95 degrees Fahrenheit, 3) unconsciousness, glassy stare, slow pul;e, and slew respiratory rate, 4) freezinc of the extremiti- s, and fir, illy, 5) death .
1. Treatment
a.
b ,
c.
Give artificial respiration, if necessary.
Bring the victim into a warm room as quickly as p ssible
Remove wet or frozen clothing and anything -.hat is constricting.
Rewarm the victim rapidly by wrapping him in warm blankets, or by placing him in a tub of water that is warm but not hot to the hand or forearm.
If the victim is conscious, give him hot liquids by mouth ( not alcohol) .
Dry the victim thoroughly if water was used to rewarm him.
Carry out appropriate procedures as describe : forfrostbite.

VI. APPENDICES
APPENDIX A
GRID LAYOUT
Prior to soil sampling, a sampling grid was established to assure proper sample location identification. Using Burns Hill Road as survey control, an approximate north-south, east-west grid pattern was laid out across the site covering areas where drums, tires, and other debris were found. The line extending from point 0 to point N2+41 was used as the grid baseline. Along this baseline, 12 sampling stations were set at 25 fort intervals. At each of these stations, east-west grid lines v -re established with grid points also at 25 foot intervals (See attached Weston Drawing BH-1).
APPENDIX B
SOIL SAMPLING
Composite soil samples were collect.ed from each grid point at the Burns Hill Read site accroding to the following procedure:
o Using a post-hole digger, a 12 inch hole was dug -at each sampling point.
o The hole was then tested for possible soil gas releases utilizing the HNU Model PI 101 Photo Ionizer. If abnormally high readings were observed, then tr.e hole was dug to 24 inches.
o With a metal sampling spoon, soil from the hole was placed in a plastic bucket from each point along a sincie east-west grid line in order to obtain a total of 100 ounces of soil to be composited.
o From the soil collected, three composite soil samples were obtained: two 120 ml VOA viles and one 32 ouncesample jar.
o Any soil remaining in the bucket was placed back into the coring holes.
o Composite soil samples were collected at all 12 east- west grid lines for a total of 36 samples.
o In order to assure that no cross contamination occurred between sampling stations, all sampling equipment was thoroughly decontaminated with soap and water.
In addition to the grid stations, a red 55-gallon drum discovered near the site entrance was also sampled. The drum contained dark soil and other miscellaneous solid waste debris. As requested by the EPA On-Scene Coordinator, two 120 ml VOA viles and one 32 ounce sample jar was collected from the drum.
All 39 soil samples from the Burns Hill Road site were collected and prepared in accordance with EPA sampling protocol and transferred to the EPA New England Regional Laboratory (NERL) for
analysis.
1 No HNU readings were observed above background, except at point
N1+50E100.Backgrould: less than 1 ppm at 0.5 span settingN1+50E100: 5 ppm at 0.5 span setting.
