The Oneida County Sanitary Landfill has operated from 1979 to the present. The four existing landfill cells were constructed based on standards that existed at their time of development from 1979 to 1995. The landfill was initially permitted as a natural attenuation landfill with a silt soil base liner and top cover. Groundwater sampling at the site showed that many constituents exceeded Wisconsin Administrative Code Chapter NR 140 (NR 140) standards throughout the 1980s. Measures that were implemented to remediate landfill impacts on groundwater quality included installation of a leachate/gas extraction system in 1990 and construction of a composite final cover over completed cells in 1994. In 1994, an Environmental Contamination Assessment (ECA) was conducted in accordance with NR 140 to evaluate landfill performance, groundwater quality trends, and future monitoring/remediation measures. Since implementation of the gas/leachate extraction system, there has been a reduction in detected volatile organic compounds in leachate, gas, gas condensate, and groundwater quality samples. Continued monitoring is necessary to evaluate remediation measures.
