Health Assessment for Delaware City PVC (Polyvinyl Chloride) Plant NPL (National Priorities List) Site, New Castle County, Delaware, Region 3. CERCLIS No. DED980551667

摘要

The Delaware City PVC Plant site is located in New Castle County, Delaware, near Delaware City. Stauffer Chemical Company and Formosa Plastics Company operate facilities on the property. Volatile organic compounds have been detected in groundwater on- and off-site and in soils on-site. Groundwater is used for water supply at residences and businesses in the site vicinity. The concentrations of volatile organic compounds recorded on-site in water-supply wells and monitoring wells exceed regulatory limits. An alternate water supply has been provided to residences on- and off-site and to off-site businesses where contaminants have been detected in water-supply wells. Remediation has been initiated for contaminant sources on-site and for groundwater quality. The site is of potential public health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects.
