About the CW4CB Project

Project Overview

The Clean Watersheds for a Clean Bay (CW4CB) project was a collaboration among the Bay Area Stormwater Management Agencies Association (BASMAA) member agencies and the USEPA designed to evaluate the effectiveness of stormwater controls for PCBs and mercury. Detailed project information is provided on the CW4CB Project Background Page and in the CW4CB Overall Project Report . The purpose of the CW4CB project was to contribute to the development of a comprehensive regional strategy for reducing PCBs and mercury loads in urban runoff to San Francisco Bay in accordance with the Total Maximum Daily Load (TMDL) plans for those pollutants developed by the San Francisco Bay Regional Water Board. The CW4CB project consisted of multiple efforts such as pilot testing pollutant control measures in locations where benefits were expected to be the greatest and evaluating the load reduction effectiveness of those measures, as well as public risk communication and other outreach efforts.

The project was facilitated through a partnership among Bay Area cities (Cities of Oakland, Richmond, San Carlos, San Jose, and Vallejo), Bay Area countywide municipal stormwater management programs, and the California Department of Public Health.  A list of the countywide stormwater management program partners along with contact information can be found on the Contacts Page.
