The Pulse of the Bay (Project)

Download the Pulse of the Bay! 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.    

Storms drive emerging contaminants into the Bay (News)

Rainfall washes contaminants from urban landscapes to San Francisco Bay, degrading water quality. In the latest RMP Update, we highlight the findings of a major multi-year screening study to quantify hundreds of emerging contaminants in stormwater. Our investigation shows that urban stormwater runoff transports toxic chemicals including PFAS, flame retardants, plastic additives, auto tire chemicals, and many others, with concentrations often similar to discharges of municipal wastewater effluent. Further characterization of emerging contaminants in stormwater is a priority for future work.

RMP Update (Project)

The Regional Monitoring Program for Water Quality in San Francisco Bay is an innovative collaboration of the San Francisco Bay Regional Water Quality Control Board, the regulated discharger community, and the San Francisco Estuary Institute. It provides water quality regulators with the information they need to manage the Bay effectively. The RMP produces two types of summary reports: The Pulse of the Bay and the RMP Update. The Pulse focuses on Bay water quality and summarizes information from all sources.

Forum on PFAS elevates the perspectives of local fishing communities (News)

Known as “forever chemicals” due to their persistence in the environment, per- and polyfluoroalkyl substances (PFAS) are a broad class of fluorine-rich specialty chemicals. Thousands of different PFAS are registered for use in consumer, commercial and industrial applications. Increased use has led to the widespread presence of PFAS in our natural environment, including San Francisco Bay. PFAS are a high priority for action at federal, state, and local levels due to the well-documented toxic properties of key members of this class of contaminants. 

Microplastics and Harmful Algal Blooms in California's waters (News)

By May 1, 2017, in time for harmful algal bloom season, a new feature will appear on California's Harmful Algal Bloom portal (http://www.mywaterquality.ca.gov/habs/) that displays satellite imagery designed to detect emerging and historical blooms. Using data and algorithms provided by NOAA's National Centers for Coastal Ocean Science, the San Francisco Estuary Institute developed a new tool under the guidance of California's Bio-accumulation Oversight Group. 

Contaminant Data Download and Display (CD3) (Project)

Contaminant Data Display and Download Tool or CD3  is an innovative visualization tool for accessing water quality data for the San Francisco Bay-Delta and northern montane regions. It is the primary tool for accessing and downloading the San Francisco Bay Regional Monitoring Program’s (RMP) long-term dataset and other project data stored in SFEI's Regional Data Center (RDC).

North Bay Mercury Biosentinel Monitoring (Project)

In 2011-2014 SFEI and UC Davis developed and implemented a multi-species biosentinel monitoring approach as an effective and efficient way of monitoring methylmercury exposure in wetland restoration projects across the North Bay. The monitoring design for this project was developed with input from a Science Advisory Group (SAG) of regional and national experts and input from local stakeholders, in order to build a design that would address questions of management concern.

RMP Annual Meeting 2016 (Event)

The RMP Annual Meeting is held every year in the early fall. The meeting is an opportunity for RMP stakeholders to discuss current RMP projects and highlight interesting new research. 

Safe to Eat Portal (Project)

Fish and shellfish are nutritious and good for you to eat. But some fish and shellfish may take in toxic chemicals from the water they live in and the food they eat. Some of these chemicals build up in the fish and shellfish - and in the humans that eat fish and shellfish - over time. Although the chemical levels are usually low, it is a good idea to learn about advisories and monitoring in water bodies where you fish, and for fish or shellfish you eat.

SFEI Provides Science Leadership and Support for State of the Estuary Report and Conference (News)

The San Francisco Estuary Partnership (SFEP) brings together the estuarine community every two years at the State of the Estuary Conference and, periodically, SFEP also reports on the State of the Estuary, summarizing the latest scientific findings about ecosystem health. This State of the Estuary Report is the only place where a holistic view of ecosystem function is provided across both the Bay and the Delta. This year, SFEI provided scientific leadership and technical support for the report, which focuses on the ties between social and ecological resilience for our estuary.

The Bay Regional Monitoring Program’s 2018 Update Report and RMP Annual Meeting (News)

New Manuscript on Pollutants in the Guadalupe River Addresses Key Questions (News)

Guadalupe River is contaminated with mercury mining wastes from runoff associated with the historic New Almaden Mining District in the upper watershed that produced 40 million kilograms during its working life (1850-1975) and with PCB and other urban pollutants from a long history of urbanization and industrial land uses.

SFEI has been monitoring pollutant concentrations in the Guadalupe River during winter storms since October 2002. The result is one of the world’s most extensive data sets on mercury, PCBs, and other pollutant concentrations and loads in an urban river.  In a recent manuscript, SFEI staff used the dataset to answer three major questions.
