  • Guided by the Pesticide Control Law and the Comprehensive Groundwater Protection Act (Minnesota Statutes 18B, 18C, 18D, and 103H) and the MDA's Pesticide Management Plan
  • Collect and analyze water samples from multiple locations throughout the agricultural areas of the state to determine the identity, magnitude of concentration and the frequency of pesticide presence in Minnesota's groundwater and surface water resources
  • Designed to assess the long-term impacts of normal pesticide use on waters within the state
  • Conduct intensive monitoring of specific areas that are more sensitive to pesticide contamination based on geology, pesticide usage or based on historical data
  • Provide data to guide activities in the Pesticide Management Plan, including the development of best management practices to minimize the impacts of pesticide application to water resources

Pesticide water quality monitoring programs include the following:

  • Surface Water
  • Groundwater
  • Edge-of field
  • Private wells
