Tomah Fairgrounds is a 10-acre area that accepted industrial and municipal waste from 1953 to 1959. After operations stopped, the area was covered and the site became part of the Tomah Fairgrounds. Groundwater and soil was contaminated with volatile organic compounds (VOCs) and heavy metals. The cleanup plan for the site is monitoring groundwater to make sure contamination naturally degrades and limiting land use with access restrictions. EPA took the site off the Superfund program�s National Priorities List (NPL) in 2001.
