Background

The Wheeler Pit site, located at County Trunk Highways O and J in LaPrairie Township, Rock County, Wisconsin, is a 3.75-acre former disposal area. It lies within a 35-acre abandoned, unlined gravel pit. Wheeler Pit originally was mined for sand and gravel by the Chicago, Milwaukee, St. Paul, and Pacific Railroad Co. In 1956, General Motors Corp. leased a four-acre portion of the pit for waste disposal. GMC also used it to dispose of paint and waste water sludges from its Janesville auto assembly plant as well as coal ashes from power plant boilers. The sludge and ash were contained by a dike at the pit.

In 1971, a liquid was found seeping on the ground from the GMC disposal area. Disposal at Wheeler Pit stopped in 1974, and it was covered at the request of La Prairie Township. From 1974 to 1988, the site was monitored intermittently for ground water contamination from arsenic, chromium, zinc, and barium.

The cleanup, which was completed in 1992, consisted of a multilayer cap, a fence around the site, waste consolidation, long-term ground water monitoring, institutional controls, and natural processes. Wheeler Pit was deleted from the Superfund list in 2004.
