Pesticides

Available Reports and Work ProductsGreen Gardener Fact Sheet


During the mid 1990’s, organophosphate pesticides (diazinon and chlorpyrifos) were identified as causing toxicity in local creeks. In May 1999, EPA listed San Francisco Bay and 35 Bay Area urban creeks as impaired by diazinon under Section 303(d) of the Clean Water Act. In response, the Program and Co-permittees developed and implemented a Pesticide Control Plan that addresses the use of pesticides within their jurisdictions; and implemented various public outreach and education efforts (at the local and regional level) which address pesticide usage.

Pesticide Monitoring Activities

The Program is conducting water quality monitoring of pesticides under the Revised Multi-Year Receiving Waters Monitoring Plan.   A full description of methods, results and conclusions relating to pesticide monitoring are presented within various Water Quality Monitoring Reports and Work Products.

Outreach at Events –Program, Co-permittee and Watershed Watch staff conduct IPM at pre-determined events. IPM fact sheets, brochures and giveaways are distributed to the public.
