Dr. Rebecca Sutton joined SFEI-ASC in 2013 as a Senior Scientist for the Regional Monitoring Program for Water Quality in San Francisco (Bay RMP). Dr. Sutton leads the RMP's Emerging Contaminants Workgroup and a team of scientists investigating contaminants of emerging concern and microplastic in the San Francisco Bay and other regions of California. She also manages SFEI-ASC’s Green Chemistry focus area, providing information to inform policies designed to prevent pollution through reduced use of toxic chemicals. Dr. Sutton has been appointed to California’s Green Ribbon Science Panel to aid in the implementation of the state’s Safer Consumer Products Regulations.

Dr. Sutton received her B.S. in Environmental Resource Science from the University of California, Davis and her Ph.D. in Environmental Chemistry from the University of California, Berkeley. Her dissertation explored molecular-scale interactions affecting contaminant fate and transport as well as soil carbon storage to mitigate climate change. Prior to joining SFEI-ASC, Dr. Sutton was a senior scientist with research and advocacy non-profit Environmental Working Group, where she conducted research on chemicals of concern in air, water, soil, consumer goods, and people.

Big problem, small size: Improving methods in microplastics research (News)

When it comes to plastic pollution, that candy wrapper half buried in the dirt is only the tip of the iceberg. Plastic bags, cigarette butts, and bottle caps are not just an eyesore, but over time they break down in the environment, creating small pieces of debris known as microplastics. Microplastics can include anything from synthetic fibers of clothing to industrial pellets from the plastic manufacturing process. Microplastics are now ubiquitous in our environment--found in our air, drinking water, sediment, and in the San Francisco Bay and global ocean.     

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 Program issues a report each year, the Pulse of the Bay in odd years and the RMP Update in even years.

Bay RMP Non-Targeted Analysis Factsheet (News)

This study used non-targeted analysis, a powerful tool that provides a broad, open-ended view of thousands of synthetic and naturally-derived chemicals simultaneously. We identified hundreds of contaminants, and the results have opened our eyes to urban stormwater runoff as an important pathway for emerging contaminants to enter the Bay.

Microplastic Pollution in San Francisco Bay and Adjacent Marine Sanctuaries (Project)

Plastic pollution is gaining global recognition as a threat to the resilience and productivity of ocean ecosystems. However, we are only just beginning to understand the scope and impacts of microplastic particles (less than 5 mm) on coastal and ocean resources, and the San Francisco Bay Area is no exception. A preliminary study of nine water sites in San Francisco Bay, published in 2016, showed greater levels of microplastics than the Great Lakes or Chesapeake Bay.

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) (Project)

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a broad class of fluorine-rich specialty chemicals. More than 4,700 PFAS are used in consumer, commercial and industrial applications, including food packaging materials, waterproof textiles, stain-resistant carpets and furniture, fire-suppression foams, processing aids for the production of fluoropolymers like Teflon, mist suppressants in metal-plating, and hydraulic aviation fluids. Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been shown to be highly toxic and have been phased out of production in the US.

Microplastic Pollution (Project)

The RMP has conducted initial studies of microplastic pollution in San Francisco Bay. Findings from a 2015 screening-level RMP study of microplastic pollution in our Bay show widespread contamination at levels greater than other U.S. water bodies with high levels of urban development, the Great Lakes and Chesapeake Bay. Wildlife consume microplastic particles; ingestion can lead to physical harm, and can expose aquatic organisms to pollutants like PCBs that the plastics have absorbed from the surrounding environment.

Contaminants of Emerging Concern Strategy (Project)

More than 100,000 chemicals have been registered or approved for commercial use in the US. For many of these chemicals, major information gaps limit evaluations of their potential risks, and environmental monitoring of these chemicals has not been required by regulatory agencies. Nevertheless, researchers and government agencies have begun to collect occurrence, fate, and toxicity data for a number of these chemicals.

PFAS Stays in San Francisco Bay (News)

SFEI senior scientist, Dr. Rebecca Sutton, published a new study in the journal Chemosphere showing that it will take almost 50 years for PFOA concentrations in water to stabilize in San Francisco Bay. This pales in comparison to the trajectory of PFOS concentrations that will not stabilize in sediment and fish for 500 years. PFOS and PFOA are harmful to humans, causing liver damage, endocrine disruption, fertility decrease, and cancer.

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).

Groundbreaking SFEI and 5 Gyres microplastics study featured in multiple media outlets (News)

Concurrent with a sold-out symposium on Oct 2nd, several media outlets, including the Mercury News, San Francisco Chronicle, and Los Angeles Times, have released the articles relating the alarming findings regarding the pervasive presence of microplastics in our surface waters. The issue of microplastics is global in nature. However, the advances in understanding the magnitude of the problem are happening regionally through partnerships with 5 Gyres, the University of Toronto Trash Team, and other notable leaders.

These scientists want you to rethink how you use plastics: SFEI and 5 Gyres issue a new video (News)

The short (3-min) video summarizes the goals of the SF Bay Microplastics Project, which aims to better understanding the distribution of microplastic in San Francisco Bay and adjacent National Marine Sanctuaries, the pathways by which these contaminants enter the Bay, and possible means of controlling their release. 5 Gyres and San Francisco Estuary Institute are collaboratively carrying out the project.

Wired Magazine: A new report shows an astounding amount of microplastics, largely from car tires, are tainting the watershed (News)

Matt Simon from Wired Magazine writes:

San Francisco Bay, like Monterey Bay to its south, is a rare success story in ocean conservation. In the 1960s, three grassroots activists—Sylvia McLaughlin, Kay Kerr, and Esther Gulick—launched Save the Bay, which beat back developers trying to fill in parts of the iconic body of water.

New Book Chapter: Pesticides in Our Homes Wash Down the Drain (News)

A state-of-the-science review of current-use pesticides in wastewater, led by SFEI senior scientist Dr. Rebecca Sutton, indicates this pollution pathway is significant and should not be overlooked. The book chapter provides a comprehensive conceptual model of all types of pesticides that have the potential to be washed down the drain and into wastewater. Conventional wastewater treatment technologies are generally ineffective at removing pesticides, so additional monitoring and modeling studies are needed to guide efforts to prevent pesticide pollution.

California Trash Monitoring Methods Project (Project)

The California Ocean Protection Council (OPC), in close partnership with the State Water Board, has recognized the importance of standard methods for trash monitoring and has funded this project. The Southern California Coastal Water Research Project (SCCWRP) and San Francisco Bay Estuary Institute (SFEI) have partnered up to test multiple trash monitoring methods with a goal of developing a library of methods with known levels of precision, accuracy, and cross-comparability of results, and linking these methods to specific management questions.
