Health Assessment for American Chemical Service, Incorporated, Griffith, Lake County, Indiana, Region 5. CERCLIS No. IND016360265

摘要

The American Chemical Service, Incorporated (ACS) site is listed on the National Priorities List. ACS began solvent recovery operations in May 1955. From 1955 until at least 1975, a variety of hazardous wastes were disposed of at various locations on the site. The environmental contamination on-site tentatively identified consists of benzene, toluene, vinyl chloride, pentachlorophenol, chloroethane, phthalates, heavy metals, cyanide, polychlorinated biphenyls, pesticides, maleic anhydride, methanol, and formaldehyde. The environmental pathways of concern are contaminated groundwater, soil, sediment, surface water, sediment, and airborne particulates and vapors. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via these environmental pathways.
