Summary: | The document draws conclusions as to the nature and extend of soil and groundwater contamination created by past spills, disposal practices, and operations and draws conclusions regarding the risks the contaminants pose to human health and the environment at CRREL. Two primary classes of contaminants, Chlorinated Hydrocarbons and Petroleum Hydrocarbons are present at the site. They are present at the source areas as vapors trapped in the pores of the fine grained soils. Locally, the contaminants are adsorbed onto soils. Contaminants are also present in the groundwater moving below the site. The primary groundwater contaminant, Trichloroethylene was found in all wells at the site, both overburden and Bedrock except for one production well near the site's southern boundary. Fractures in bedrock are infrequent. Petroleum Hydrocarbons were detected primarily in soil samples, with low concentrations identified in samples from the monitoring wells. Evaluation of the health risk posed by the contaminants was performed by identifying potential scenarios through which on- site workers, children and visitors may come in contact with the contaminated materials. For all present and foreseeable future use scenarios, no risk was identified. No ecological risks or impacts were identified.
