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.

EPA completed a review of the site's cleanup in 2012. This type of review is required at least every five years where the cleanup is complete but hazardous waste remains managed on-site. These reviews are done to ensure that the cleanup continues to protect people and the environment.
The review included:
- An evaluation of background information
- Cleanup requirements
- Effectiveness of the cleanup and any anticipated future actions
- Maintenance and monitoring efforts
- An analysis of ways for EPA to operate more efficiently
The review found that the cleanup continues to protect people and the environment. The next scheduled review will be in 2017.
Although the site use is consistent with current deed and land-use restrictions, referred to as institutional controls, EPA is working with the landfill’s owners and the Wisconsin Department of Natural Resources to review and update them, if necessary.
