Bay Regional Monitoring Program

The Bay Regional Monitoring Program (RMP) provides water quality regulators and policy-makers with information they need to manage the Bay effectively. The RMP is an innovative collaborative effort between SFEI, the Regional Water Quality Control Board, and the regulated discharger community. The Program was established in 1993, and has an annual budget of $3.5 million. more >

A recent RMP technical report summarizes RMP investigations of the flame retardants polybrominated diphenyl ethers (PBDEs) in the Bay. Studies of PBDEs in people and wildlife in the Bay Area in the late 1990s and early 2000s indicated that the region was a global PBDE contamination “hot spot.” State and federal governments responded to the rising concerns over PBDEs by enacting bans and encouraging voluntary phase-outs. Likely in response to the phase-outs and bans, RMP monitoring indicates a decline in contaminant levels for Bay organisms that are routinely monitored. This decline is expected to continue, and should diminish any potential impacts of PBDEs on Bay biota.


Phil Trowbridge, formerly of the Piscataqua Region Estuaries Partnership and the New Hampshire Department of Environmental Services, joins SFEI to serve as the San Francisco Bay RMP Manager. SFEI feels very fortunate to attract such a high-caliber professional engineer with an admirable list of accomplishments.


The RMP sponsored a forum to review information and information needs relating to managing methylmercury in restored tidal marshes in San Francisco Bay. The forum was held to address a lack of consensus on the best approach for monitoring methylmercury and using monitoring data in decision-making. The forum addressed the state of knowledge regarding the role wetland restoration and management play in methylmercury impairment locally and regionally, and helped inform decision-making by the San Francisco Bay Regional Water Quality Control Board and other agencies.
