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 structural and non-structural controls to assist stormwater managers in meeting pollutant reduction targets. 

The purpose of the CW4CB project was to contribute to the development of a comprehensive regional strategy for reducing PCBs, mercury, and other sediment-associated pollutant 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 Quality Control Board. The CW4CB project consisted of multiple efforts, such as pilot testing structural and treatment-based pollutant control measures to assess the effectiveness of those measures, as well as public risk communication and other outreach efforts.

The CW4CB Project was a collaborative effort of municipalities, NPDES permittees, technical advisors, and regulatory agencies with the overall goal of assisting stormwater managers in developing understanding that could be applied to support regional pollutant reduction efforts. The monitoring program included multiple related investigations to support future efforts to reduce stormwater loadings of priority pollutants. These efforts included components to identify important source properties and refer to regulators for cleanup, assess enhanced municipal maintenance operations as a means for removing pollutant loads from the stormwater system, and measure pollutant removal efficiencies associated with a variety of structural treatments installed as part of the Project. 

AMS managed the monitoring program in support of this multi-year, multi-million dollar effort and advised the Technical Advisory Committee in overall implementation. Specific activities completed by AMS included development of the programmatic Quality Assurance Project Plan (QAPP) and monitoring plans associated with each Project component for approval by EPA. AMS also participated and managed multiple subcontractors in conduct of monitoring, quality assurance, and data management activities, and several commercial laboratories in design and conduct of the analytical program.
