This report from the Regional Monitoring Program for Water Quality in San Francisco Bay features articles on the four major pathways by which pollutants enter the Bay: municipal wastewater, industrial wastewater, stormwater, and dredging and dredged sediment disposal. Each article provides a basic introduction to the pathway and discusses the regulatory framework, recent findings, and future challenges. The report also includes some of the latest highlights from monitoring of important parameters such as nutrients, emerging contaminants, mercury, PCBs, and selenium.
CD3 or Contaminant Data Display and Download is a web-based visualization tool for accessing water quality data for the San Francisco Bay-Delta region, including the RMP’s long-term dataset. The tool has been redesigned to leverage SFEI’s other interactive mapping efforts and debuts impressive new functionality, including enhanced spatial querying and generating dynamic statistical summaries and charts.
Other key benefits of the redesigned tool include:
The RMP has produced a synthesis report on PCBs that summarizes recent advances in understanding and makes recommendations for future studies. The report addresses nine priority management questions articulated by the RMP PCB Strategy Team.
The Annual Meeting of the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) was held on Tuesday, October 14, 2014 at the David Brower Center in Berkeley, CA from 9 AM to 4 PM.
We had an exciting line-up of speakers on the following topics:
Phil Trowbridge is the Program Manager for the Regional Monitoring Program for Water Quality in San Francisco Bay. The Bay RMP is a novel, multi-faceted regional monitoring program that uses pooled resources from dischargers and dredgers of San Francisco Bay to conduct and coordinate studies aimed at evaluating ecosystem health, characterizing sources and fate of contaminants, and informing potential management actions.
The Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) recently published a technical report, authored by Dr. Rebecca Sutton of SFEI and her colleagues, that summarizes a series of RMP monitoring and research projects that have investigated the impacts of the flame retardants polybrominated diphenyl ethers (PBDEs) in San Francisco Bay.
This report contains information on the summer 2023 field sampling efforts conducted by the San Jose State University Research Foundation’s (SJSURF) Marine Pollution Studies Lab at Moss Landing Marine Labs (MPSL-MLML) in support of the Regional Monitoring Program’s (RMP) Central and South Bay Near-field and Margins chemical contaminant study. The work was contracted through the San Francisco Estuary Institute (SFEI) to SJSURF to collect sediment and prey fish tissue samples.
This report includes sample collections over a four week period (August 21st through September 14th) encompassing four trips. A total of 38 sediment and 12 prey fish sites were sampled, three of which included collecting duplicate sediment samples (Appendix A). Detailed sample counts and protocols can be found in the “2023 Bay Prey Fish and Near-field / Margins Sediment Sampling and Analysis Plan” prepared by SFEI.
This report details activities associated with the biannual Regional Monitoring Program for Water Quality in the San Francisco Estuary (RMP) water cruise. The RMP water sampling program was redesigned in 2002 to adopt a randomized sampling design at thirty-one sites in place of the twenty-six “spine of the Estuary” stations sampled previously. In 2007, the number of sites was decreased to twenty-two stations, combined probabilistic and historic, and it remained as such for 2023.
In U.S. Pacific Northwest coho salmon (Oncorhynchus kisutch), stormwater exposure annually causes unexplained acute mortality when adult salmon migrate to urban creeks to reproduce. By investigating this phenomenon, we identified a highly toxic quinone transformation product of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), a globally ubiquitous tire rubber antioxidant. Retrospective analysis of representative roadway runoff and stormwater-affected creeks of the U.S. West Coast indicated widespread occurrence of 6PPD-quinone (<0.3 to 19 micrograms per liter) at toxic concentrations (median lethal concentration of 0.8 ± 0.16 micrograms per liter). These results reveal unanticipated risks of 6PPD antioxidants to an aquatic species and imply toxicological relevance for dissipated tire rubber residues.
