Water Resources Protection
WSDA is charged with protecting Washington state's ground
and surface water resources from contamination by fertilizers and
By working with the agricultural community and regulators to
provide technical assistance to pesticide applicators, WSDA assures that
pesticides which pose a risk to water resources are being handled and
applied according to the Federal Insecticide, Fungicide, and Rodenticide Act
(FIFRA) label. Pesticides determined by EPA to post a risk to water
resources have special use language on FIFRA label.
WSDA also partners with the U.S. Geological Survey and the
Washington State Departments of Ecology and Health to monitor water
resources for pesticide residues and to assess the effects of pesticides on
surface and ground water.
