Contamination potential in the Silurian Dolomite aquifer, eastern Wisconsin

Water-Resources Investigations Report 78-108



The Silurian dolomite aquifer is used for water supply in much of a 14-county area bordering Lake Michigan in eastern Wisconsin. Because of the rapidity of ground-water movement, the aquifer is susceptible to contamination by waters percolating downward from surface sources. Maps showing the distribution of permeability, the thickness of unconsolidated materials, and the depth to the water table are combined to show areas where the dolomite aquifer has the greatest contamination potential. Several areas have above-normal potential for contamination. These include the Casco-Luxemburg area of Kewaunee County, the area south of Chilton in Calumet County, a part of western Manitowoc County, drainageway areas in Sheboygan County, the Byron-Campbellsport area of Fond du Lac County, the Sussex-Lannon-Cedarburg areas of Waukesha and Ozaukee Counties, and the Racine-Burlington areas of Racine County.
