List of Superfund sites in Wisconsin

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a list of Superfund sites in Wisconsin designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.[1] These locations are known as Superfund sites, and are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation.[2] As of March 26, 2010, there were 38 Superfund sites on the National Priorities List in Wisconsin.[2] One additional site has been proposed for entry on the list.[2] Six sites have been cleaned up and removed from the list.[2]

WID039052626 Moss-American (Kerr-McGee Oil Co.) Milwaukee Groundwater samples showed elevated levels of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs). Free-standing creosote or an oil sheen was observed in three monitoring well samples; similar observations were noted in eight test pits. The primary contaminants detected in the River sediments are PAHs. Contaminants that were found in the soil in the processing area and vicinity, the treated wood storage area, and the northeast and southeast landfills include components of creosote: PAHs, benzene, ethylbenzene, toluene, and xylenes (BTEX) compounds. PAHs were detected in a ditch that drains water from the site to the River. The Little Menomonee River has been affected by contaminated surface water runoff and sediments from the site. Potential health risks exist for individuals inhaling volatilized chemicals or ingesting or coming into direct contact with the contaminated sediments, soil, groundwater, or surface water.
