Health Assessment for Avco Lycoming (Williamsport Division) Site, Williamsport, Pennsylvania, Region 3. CERCLIS No. PAD003053709

摘要

The Avco Lycoming (Williamsport Division) site is an aircraft engine production facility on a 28-acre site in urban Williamsport, Pennsylvania. The plant includes a still for the reclamation of petroleum solvents and, since 1950, a waste treatment facility. Environmental sampling indicates that the contaminants of concern are volatile organic compounds present in groundwater, including trichloroethylene, 1,2-trans-dichloroethylene, vinyl chloride, 1,1-dichloroethylene and chloroform. Chromium was also found in an on-site recovery well. The site is considered to be of public health concern because of the risk to human health caused by the likelihood of past exposure and the possibility of future exposure to hazardous substances via contaminated groundwater.
