NPL Site Narrative for American Chemical Service, Inc.

Griffith, Indiana

Federal Register Notice:  September 21, 1984

Conditions at listing (September 1983): American Chemical Service, Inc., recycled chemicals in Griffith, Indiana, from 1958 to 1975, when it voluntarily stopped using two disposal areas on-site and covered them. The State has responded to complaints about the company since 1972. The site contains buried drums (estimated at 20,000) and sludges (primarily pigment and resins); the amounts, nature, and source are unknown.

The shallow aquifer beneath the site is contaminated with pentachlorophenol, benzene, toluene, vinyl chloride, 1,1,1-trichloroethylene, and other organic compounds, according to analyses conducted for the State. The majority of the 10,000 people residing within 3 miles of the site obtain drinking water from the lower aquifer. No contamination of drinking wells has been documented to date. The aquifers are separated by a supposedly continuous 15- to 25-foot layer of clay. The site is entirely mantled by sandy soil with high permeability. Ground water flows primarily to the northwest.

Status (June 1984): EPA has completed a search for parties potentially responsible for wastes associated with the site.
