The Tomah Fairgrounds Landfill (TFL) is located in the southeatern portion of the City of Tomah, Wisconsin. The TFL property covers roughly 37½ acres, with the landfill itself occupying 15 acres within the boundaries of the Fairgrounds. The landfill area is a grass-covered open field that is often used as a parking lot during Fairground events. The site is bordered on the north by Grassman Street and a residential area. Fair Street runs along the eastern border, angles across the southeast corner and borders the Fairgrounds along the south. Further east lies a commercial/industrial area. To the south and southwest are seven homes with private drinking water wells and open fields. To the west is an open field. Besides the seven homes to the south and southwest, the remaining residences around the Fairgrounds are supplied drinking water by the City of Tomah municipal service.The TFL was used and operated by the City of Tomah as a disposal site before the Tomah Municipal Sanitary Landfill was developed. Landfilling occurred at the site from 1955 until the site was closed in 1960. Upon its closure, waste disposal was transferred to the municipal sanitary landfill.Waste disposal methods consisted of excavating 6 to 8 feet of soil, landfilling, placement of a cover consisting of previously excavated soils, and a final grading process. Some material disposed of in the landfill may have been burned before it was buried. No disposal records regarding the types or quantities of material buried were maintained.The site was investigated in 1984. The site was placed on the National Priorities List (NPL) in 1987. The possible effects of disposal directly into an aquifer, and the potential for direct contact with hazardous substances because of erosion of the landfill cap, were the concerns raised during the preliminary assessment.
Remedy:  It has been found that no further action is appropriate due to properly implemented deed restrictions limiting land uses and an agreement between the City of Tomah and the Wisconsin Department of Natural Resources (WDNR) implementing natural attenuation of groundwater.
