Background

The 28-acre Hagen Farm site is located at 2318 County Highway A, approximately one mile east of the city of Stoughton, Dane County, Wisconsin. Approximately 10 acres was used as a disposal area. The site was operated as a sand and gravel pit prior to the late 1950s. The gravel pit was then used for disposal of waste materials from the late 1950s to the mid-1960s. Chemical waste has adversely affected soil and ground water.

It was placed on the National Priorities List in July 1987. Waste Management of Wisconsin, one of the companies connected to the site, paid for studies and the cleanup of about 68,000 cubic yards of waste, including municipal refuse, paint sludges, grease, rubber, plastic sheeting, and several industrial chemicals.

The contaminants of greatest concern in the ground water were volatile organic chemicals (VOCs). The most prevalent of these was tetrahydrofuran and vinyl chloride. Although VOCs were not found in any private wells during the investigation, it was determined that contaminants in the waste and ground water posed a risk to human health.

A cleanup plan for an on-site waste was signed in September 1990. It called for consolidating three waste disposal areas into one, capping the consolidated waste, and installing and operating an in-place vapor extraction system. Another plan to pump and treat contaminated ground water was signed in September 1992.

In general, the site had been cleaned up. Waste consolidation and capping were completed in May 1992. The cap was designed to eliminate the threat of direct contact with the waste and to reduce the potential for additional contamination going into the ground water. The vapor extraction system was installed in February 1994 and is currently operating. The system was designed to treat contaminants in the waste disposal pit by drawing out volatile contaminants. Construction of the ground water pump and treat system was completed in April 1996 to keep contaminated ground water from affecting nearby residential ground water drinking wells and to restore the ground water aquifer to usable conditions. Annual monitoring of area private wells has not shown contamination.

Latest Update

September 2011

EPA has completed a status review of the cleanup. 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:

The review found that the cleanup continues to protect people and the environment. The next scheduled review will be in 2016.  The fourth five-year review (PDF) (155pp, 8.2MB) details the site's progress.
