Law – The Pesticide Contamination Prevention Act

Back to Ground Water Protection Program

DPR began addressing pesticide contamination of ground water in the early 1980’s after the discovery of contamination from the legal application of the fumigant dibromochloropropane (DBCP). Reports of additional pesticides in ground water resulted in the passage of the Pesticide Contamination Prevention Act (PCPA) in 1985.

The PCPA (Food and Agricultural Code Sections 13141-13152) requires DPR to:

  • Obtain environmental fate and chemistry data for agricultural pesticides before they can be registered for use in California.
  • Identify agricultural pesticides with the potential to pollute ground water.
  • Sample wells for presence of agricultural pesticides in ground water.
  • Obtain, report and analyze the results of well sampling for pesticides conducted by public agencies.
  • Formally review a detected pesticide to determine if its continued use can be allowed.
  • Adopt use modifications to protect ground water from pollution if the formal review indicates that continued use can be allowed.

Reports mandated by the PCPA:
