Protecting Surface Water Fact Sheet (En Español)

The Department of Pesticide Regulation's (DPR) Surface Water Protection Program protects human health and the environment by preventing pesticides from adversely affecting our surface waters, by addressing both agricultural and nonagricultural sources of pesticide residues in surface waters. It has preventive and response components that reduce the presence of pesticides in surface waters.

The preventive component includes local outreach to promote management practices that reduce pesticide runoff. Prevention also relies on DPR's registration process in which potential adverse effects to surface water quality, particularly those in high risk situations, are evaluated. The response component includes mitigation options to meet water quality goals, recognizing the value of self-regulating efforts to reduce pesticides in surface water as well as regulatory authorities of DPR, the State Water Resources Control Board (SWRCB) and the Regional Water Quality Control Boards (RWQCB).
