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.

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.

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.

Maanvi Singh from the US edition of the Guardian, based in the UK, writes, “It was basically everywhere we looked,” said Rebecca Sutton, an environmental scientist at the San Francisco Estuary Institute, a local institution that led the three-year, $1.1m research effort.

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.

The San Francisco Estuary Institute and the 5 Gyres Institute have completed a first-of-its-kind, comprehensive regional study of microplastic pollution of a major urban estuary and adjacent ocean environment.

A new study from SFEI assessing the ability of rain gardens to remove contaminants from urban stormwater has shown that nature-based filtration may also be a solution for microplastic pollution. This solution and others will be featured in a symposium on microplastics for scientists, policy makers, and change leaders in Berkeley on October 2nd.

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.

SFEI’s Diana Lin and Tony Hale will be presenting at the California Water Boards Water Data Science Symposium on July 1-2, 2019.  Diana Lin will be sharing preliminary results from SFEI’s Microplastic Monitoring in San Francisco Bay and Adjacent National Marine Sanctuaries study, which is the first comprehensive regional study of mic

Highlighted in the December 2018 issue of Estuary News, a new report from the Bay’s Regional Monitoring Program documents the presence of numerous medications in the region’s wastewater. In 2016 and 2017, seven wastewater treatment facilities located throughout the Bay Area voluntarily collected wastewater samples and funded analyses for 104 pharmaceutical compounds.

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.

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.

SFEI science will feature prominently at the Sixth International Marine Debris Conference in San Diego next week:

Rebecca Sutton, Meg Sedlak, and Diana Lin of SFEI, in partnership with Carolynn Box of 5 Gyres, conducted ocean water sampling associated with an ambitious project. The project is focused on determining the characteristics and fate of microplastics in the Bay and adjacent ocean waters. KQED reporter Lindsey Hoshaw published a story covering the team's activities along the California coast. After determinng that the Bay has greater than expected microplastic pollution, the science team, as reported by Hoshaw's story, is conducting further ground-breaking research.

Global leaders in the study of emerging contaminants, the stakeholders that make up the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) believe that preventing a pollution problem is safer and more cost-effective than cleaning one up. For this reason, the RMP focuses on monitoring contaminants of emerging concern, or CECs.

SFEI and The 5 Gyres Institute have launched an ambitious two-year research project to monitor San Francisco Bay for pollution in the form of tiny particles of plastic pollution, reports ABC7 News. These microplastic particles are eaten by local fish, according to previous studies, which can expose them to harmful contaminants.
