Bioaccumulation Oversight Group
The Bioaccumulation Oversight Group (BOG) is a subcommittee of the Water Boards' Surface Water Ambient Monitoring Program (SWAMP) Roundtable that provides oversight of SWAMP's statewide Bioaccumulation Monitoring Program. The mission of the BOG is to assess the impacts of contaminants in fish and shellfish on beneficial uses in California water bodies through statewide monitoring under SWAMP and perform syntheses of information from these statewide monitoring efforts and other studies.
The BOG is also a workgroup of the California Water Quality Monitoring Council, and in this role manages the Safe to Eat Portal and is a forum for coordination of bioaccumulation monitoring in California. Please see the Workgroup Charter for more information.
In September 2006, SWAMP formed the BOG to develop plans for and to guide the implementation of SWAMP's statewide Bioaccumulation Monitoring Program. The California Water Quality Monitoring Council designated the BOG as its workgroup for assessing "Is it safe to eat fish and shellfish from our waters?" and directed this workgroup to develop the Safe to Eat Portal, which is devoted to this theme. The BOG convened a Bioaccumulation Peer Review Panel to provide evaluation and peer review of the BOG activities. The members of the Panel are internationally recognized authorities on bioaccumulation monitoring.
Since 2007, the BOG has been conducting surveys focused on collecting and analyzing fish tissue for mercury, legacy pesticides, and other bioaccumulated pollutants, such as PCBs, and assessing these data to provide insight into the safety of eating sport fish. These surveys have been conducted in lakes and reservoirs, rivers and streams, and coastal waters of California. From 2012 – 2013, the BOG conducted a study of methylmercury bioaccumulation in birds on California lakes and reservoirs (known as the wildlife survey). See the figure below for a timeline of the different bioaccumulation monitoring surveys the BOG has conducted and plans to conduct through 2032.
Other BOG activities have included reviews of historic bioaccumulation monitoring data and assessments in California, including:
- A review of the historic Toxic Substance Monitoring (TSM) and State Mussel Watch (SMW) Programs
- A review of historic bioaccumulation of pollutants and their impacts on fishing an aquatic wildlife in California waters
Membership is open to anyone with an interest in bioaccumulation, fish advisory development, and statewide bioaccumulation monitoring efforts.
- Chance to connect with potential collaborators
- Opportunity to participate in statewide monitoring efforts
- Access to multiple datasets
- Contribute to science and resources supporting fish advisory development in California
