3. Site Characterization

3.1 Background Information

The Tinkham Garage Superfund Site covers approximately 375 acres near the intersection of Interstate Route 93 and New Hampshire State Route 102. The site has been developed for residential use with condominiums and single-family homes. The undeveloped areas of the site consist of wooded areas, open fields, and wetlands. Available historical information suggests that volatile organic compounds (VOCs) were discharged in the area behind the Tinkham Garage and on the Woodland Village Condominium property. As a result, VOCs have been found in soil and both overburden and bedrock ground water at the site.

32 Hazard Evaluation

Perimeter Establishment:

Map/Sketch Attached: See Figures HS-1 and HS-2 Perimeter Identified: See Figure HS-1 Zone(s) of contamination identified: One source area near Tinkham Garage.

Site Status: Inactive




Waste Types: Liquid, Solid

Includes the following:

• Ground water Soils

Refer to Tables 1 and 2 for listing of chemicals of concern.

Known or Suspected Hazardous/Toxic Materials: Volatile organic compounds (VOCs) in soil and ground water.

The primary concern at the Site is contamination of surface and near-surface soil by the former release of VOCs. The potential for encountering soil containing VOCs in the approximate source area near Tinkham Garage is moderate to low (Figure 2 of SAP). To reduce the likelihood of being exposed by VOCs associated with this areas during field activities, efforts should be made to avoid walking or disturbing soils unnecessarily in this area.

Exposure to hazards from chemicals during field activities are most likely to occur by one or more of the following:

1. Direct contact with contaminated surficial and subsurface soils or ground water;

2. Inhalation of volatile organic compound vapors while performing subsurface explorations.

Toxic and Pharmacological Effects: Refer to the NIOSH Guide to Chemical Hazard. Acute exposure to VOCs may result in dizziness or nausea. A summary of NIOSH information concerning VOCs present at the site is provided in Tables 1 and 2. The results of chronic exposure may include, but are not limited to, central nervous system depression, liver and kidney damage, and irritation of skin, eyes, and respiratory passages. Many VOCs are known or suspected carcinogens. Routes of exposure include inhalation, topical, and ingestion.

Heat Exposure Effects: Since the work on-site is planned to be performed in the spring, heat exposure effects are not likely to be a significant concern. Heat-related illnesses may be caused by excessive or long-duration activity in protective clothing




when air temperatures are greater than approximately 70" F. Heat-related illnesses range from heat fatigue to heat stroke, the latter being the most serious. Heat stroke requires prompt treatment to prevent irreversible damage to health. Protective clothing may have to be cut off. Less serious forms of heat stress require prompt attention to prevent further complications which may lead to heat stroke. Unless the victim is obviously contaminated, decontamination procedures should be omitted or minimized so that treatment may begin immediately. If work is performed in warm weather, precautions will be taken to minimize the potential for personnel to suffer heat-related illnesses. Drinking water will be available to on-site personnel during work performed in warm weather. The on-site Health and Safety Officer will be required to consider the need to modify the work schedule to reduce the potential for heat exposure to personnel.

Cold Exposure Effects: Cold exposure effects are also not likely to be of concern during subsurface explorations. Hypothermia may result from personnel exposed to excessive cold. Hypothermia requires prompt treatment to prevent serious damage to health. Damp or wet clothing may have to be cut off and the person's body temperature must be elevated as soon as possible through the use of warm blankets or another person's body warmth. Unless the victim is obviously contaminated, decontamination procedures should be omitted or minimized so that treatment may begin immediately. If work is performed during cold weather (below approximately 45° F), precautions will be taken to minimize the potential for hypothermia. Precautions may include not working in inclement weather or allowing time for personnel to take steps necessary to increase their body temperature.

4. Field Activities

Borings will be drilled and test pits will be excavated during the subsurface explorations program. Permeability (hydraulic conductivity) tests will be performed and observation wells installed in selected borings. Water used in advancing borings and performing permeability tests will consist of potable water. All borings and test pits will be performed in areas outside of the identified source area (Figure HS-2). However, the explorations may be performed at locations of low concentrations of VOCs in ground water. Soil samples will be collected from the borings and test pits for soil classification and index testing. Decontamination materials such as methanol may be used. The following physical hazards may exist:



Date March 18, 1992 PageS

• Exposure to ambient on-site conditions (VOC vapors in soil or ground water);

• Dermal contact with contaminated water and soil during boring and test pitting operations;

• Dermal contact with decontamination materials;

• Exposure to the elements (weather);

• Fatigue.

Site Monitoring Equipment: HNu Photoionization Detector (PID)

5. Personnel Protective Equipment

Recommended Level(s) of Protection: Level D

On-site personnel will use Level D personnel protection during all field activities.

Protective Clothing

Sampling personnel in these areas will wear:

• Hard hat and hearing protection where working within 50 feet of heavy equipment;

• Work boots; • Work clothes or coveralls; • Viton protective gloves when handling soils or in contact with water; • Safety glasses or eyeglasses for splash protection.

Personnel will cease all activities in the vicinity of the test pit or boring if sustained PID readings exceed 5 parts per million (ppm) during excavation or drilling. PID readings within five feet of the boring or test pit will be made to determine if personnel can return to the area of the exploration. If PID readings decrease to background levels (generally 0 to 1 ppm), the boring or test pit will be backfilled, the location abandoned and an alternate location selected to perform the exploration. Excavation or drilling equipment will be decontaminated as described in Section 6 prior to continuing operation at the alternate location. Upgrade to Level C will not be performed without




further consultation with the Project Engineer. If work in Level C is performed, this Health and Safety Plan will be modified to specify procedures for work under this level of protection.

6. Decontamination and Disposal

An area where decontamination will be performed will be assembled in the area of each exploration. The decontamination zones will be established such that personnel and equipment are fully decontaminated prior to leaving each exploration. In addition, all personnel will be familiar with proper decontamination procedures prior to going on site. All drilling and excavation equipment shall be decontaminated prior to arriving on site.

Since explorations will be performed outside of the source area and the probability of encountering contaminated soil or ground water appears to be moderate to low, procedures have been developed for decontamination of personnel and equipment involving contact with uncontaminated media with contingencies for decontamination associated with contact with contaminated media.

6.1 Personnel Decontamination

The personnel decontamination sequence after performing subsurface explorations is as follows:

a. Samples and hand equipment are dropped on plastic sheets.

b. Loose soil will be removed from gloves with a brush, washed with soapy water, and rinsed with clean water. If VOCs were not detected by PID screening during explorations, wash waters will be disposed of on the ground surface near each exploration. If contaminated soil or ground water was encountered, gloves will also be rinsed with methanol during decontamination, and wash water will be drummed.

c. Surgical gloves are removed and disposed in the "Dry Decon" drum.

d. Drums shall be sequentially numbered and labelled with their contents, and will be secured on-site until proper disposal is arranged.




62 Equipment Decontamination

The equipment decontamination procedure for all activities performed at the site is as follows:

a. All disposable items (e.g. plastic sheeting, plastic bags, etc.) will be discarded in the "Dry Decon" drum.

b. All sampling and testing equipment contacting on-site surface soils and ground water will be decontaminated. Water level indicators will be decontaminated with soapy water, then rinsed with clean water. Air monitoring equipment will be wiped with methanol-soaked paper towels. Waste paper towels will be disposed of in a "Dry Decon" drum.

c. All boring and test pitting equipment contacting uncontaminated on-site surface soils or ground water will be decontaminated. The equipment will be decontaminated by removing loose soil by brushing and rinsing equipment with high pressure potable water. Wash water will be disposed of on the ground surface within 5 feet of the completed exploration. Water produced during decontamination will be disposed of such that surface runoff drains toward the area of the exploration and does not discharge to any surface water bodies or catch basins.

If equipment contacts apparently contaminated soil or ground water, the equipment will be steam-cleaned on plastic sheeting, and wash water will be collected and drummed. Plastic sheeting will be disposed of in a "Dry Decon" drum.

d. Drums shall be sequentially numbered and labelled with their contents, and will be secured on-site until proper disposal is arranged.

63 Soil Sample Management

The procedure for handling of soil samples will be as follows:

a. The headspaces of the soil samples will be measured with a PID. If PID reading from a sample headspace exceeds 1 ppm, the sample will be returned to the exploration from which it was obtained.




b. The exterior of the sample containers to be removed from the work area will decontaminated by using a brush to remove soil.

6.4 Ground Water

All ground water evacuated during the subsurface exploration program or drilling water used to advance borings or perform permeability tests will be disposed within five feet of the exploration. Purged ground water will be disposed such that surface runoff does not discharge to any surface water bodies or catch basins.
