Abstract:
Abstract: There is considerable interest in Wisconsin in relating soils, geologic, and hydrogeologic characteristics as well as land-use history to atrazine detections in order to improve the regulations and recommendations for the future uses of this pesticide and similar chemicals. At present, there are no clear-cut indicators to predict where atrazine detections may occur.
The goals of this study are to 1) inventory and automate land-use and natural resource information for Dane County, and 2) to identify the soils, geologic, and hydrogeologic features that make an area susceptible to atrazine contamination. Atrazine data for 397 wells in Dane County were compiled from the Grade A Dairy Farm Well Water Quality Survey, the Rural Well Survey, and Bradbury and McGrath’s (1992) study.
