NPL Site Narrative for Old Southington Landfill

Southington, Connecticut

Federal Register Notice:  September 21, 1984

Conditions at listing (September 1983): Old Southington Landfill covers 6 acres in Southington, Connecticut. It is suspected of contaminating the town's Production Well Number 5, which is 500 to 600 feet away and about 3,500 feet east of the Quinnipiac River. The landfill, which the town operated from 1947 to 1967 as a municipal landfill, also accepted hazardous waste. An industrial park and several homes have been built on top of the old landfill. Well Number 5 contains significant concentrations of volatile organic compounds, particularly 1,1,1-trichloroethane, according to analyses done by the State. Volatile organics are also present in nearby surface waters. A hydrogeologic investigation conducted by EPA suggests that the abandoned landfill is a source of volatile organics entering area ground water. An intensive hydrogeologic study is needed to determine flow patterns of local ground water, which will help further define the source(s) of contamination.

Status (June 1984): The State has discussed with the town issuance of an order requiring the town to hire a contractor to conduct a remedial investigation/feasibility study. The work would include the intensive hydrogeologic study. The town is presently soliciting proposals for the study.
