Stage of Clean-up: Construction Completed
Conditions at proposal (June 24, 1988): Tippecanoe Sanitary Landfill, Inc. (TSL) operates a 51-acre landfill in Lafayette, Tippecanoe County, Indiana. In 1971, the company received a permit from the State to accept municipal waste. Open dumping had occurred for an unknown period prior to that date. In 1978, the State did not renew the site's operating permit because of shallow ground water and highly permeable subsurface materials at the site. A series of appeals followed, and the facility is currently operating without a permit. In 1979, ALCOA, Lafayette, Indiana, advised the State that its aluminum-lime sludge, which had been hauled to the site since 1973, had been found to contain significant levels of PCBS. Disposal of the sludge ceased, but considerable quantities had already been deposited at the site. In December 1983, the Indiana State Board of Health found that a nearby well contained PCBS and ACETONE, as well as LEAD and CADMIUM, at levels exceeding Federal primary drinking water standards. An estimated 81,000 people obtain drinking water from public and private wells within 3 miles of the site. More...
