Identifying Potential Pesticide Contaminants

Back to Ground Water Protection Program
Back to Law

DPR requires environmental fate and chemistry data for all agricultural pesticides. These data are used to identify and sample for pesticides with the greatest chance to contaminate ground water.

  • Pesticide Chemistry Data
    Pesticide chemistry data provided by registrants of agricultural pesticides and used by DPR to identify potential ground water contaminants and fulfill mandated reporting requirements.
  • Potential pesticide contaminants - regulations
    Regulations adopted by DPR to identify pesticides that have the potential to pollute ground water based on their chemical properties and labeled uses.
  • Sampling for potential pesticide contaminants
    DPR samples for agricultural pesticides identified as potential contaminants to determine if their legal use may contaminate ground water and to better understand their fate and behavior in the environment.
