How much data is enough? Detailed geologic mapping near a Superfund Site, Wauconda, Illinois

Detailed geologic mapping was undertaken in northeastern Illinois to provide officials at state, county, and local agencies a better understanding of Quaternary deposits for environmental, resource, and planning issues. The regional geological framework was developed from mapping in the Wauconda and Grayslake Quadrangles for the National Cooperative Geologic Mapping (STATEMAP) Program (Stumpf et al., 2004; Stumpf, 2004) and the Antioch Quadrangle for the Central Great Lakes Geologic Mapping Coalition (Hansel, 2005) in (Figs. 1 and 2). Specifically, on the Wauconda Quadrangle, officials will use this information to help predict groundwater flow and contaminant potential in the vicinity of a Superfund Site.
