The Wisconsin Department of Agriculture, Trade and Consumer Protection (WDATCP) is responsible for managing pesticides to protect water quality. Until recently, groundwater quality concerns, predominantly related to atrazine contamination, have driven the research funded by WDATCP and the regulations adopted by the department to achieve compliance with groundwater standards. While the department has shown the presence of herbicides in surface water through joint studies with the U.S. Geological Survey, the lack of surface water standards for most pesticides has prevented an assessment of potential or actual environmental impacts. Currently, no WDATCP regulations have been developed based on surface water contamination due to pesticide use. However, during 2003, the U.S. Environmental Protection Agency (EPA) issued new health and environmental risk assessments for atrazine which placed greater concern on potential surface water impacts versus groundwater impacts. In response, WDATCP has expanded its surface water monitoring efforts while maintaining groundwater monitoring and pesticide management activities. This paper will touch on recent research developments, proposed Wisconsin atrazine regulations, and pending federal actions which will affect the management of pesticides in Wisconsin.
