Pesticide Reduction Evaluation for Cranberry Bog Drainage in the Grayland Area
Pesticide Reduction Evaluation for Cranberry Bog Drainage in the Grayland Area (Number of pages: 69) (Publication Size: 677KB)
|Best management practices have been implemented by cranberry farmers along the Washington Coast to reduce pesticide concentrations in surface runoff. Water quality sampling was conducted to evaluate compliance with water quality standards during the peak pesticide application period.
Three sites were sampled in the Grays Harbor County ditch, and six sites were sampled in the Pacific County ditch. Samples were collected one week prior to pesticide application, during the week of peak application, and two weeks following application.
Organophosphorus and carbamate pesticides were targeted for evaluation. Data also were made available for chlorinated and nitrogen-containing pesticides that were inadvertently analyzed by the laboratory.
