CEC Regional Monitoring

Regional Monitorng CEC Information and Resources

Bioaccumulation Monitoring Program - Addresses whether fish found in California's streams, lakes, and coastal areas are safe to eat by measuring contaminant concentrations in fish tissue. The Safe to Eat Workgroup (Workgroup), formerly known as the Bioaccumulation Oversight Group (BOG) guides the implementation of the Bioaccumulation Monitoring Program.

Central Coast Ambient Monitoring Program (CCAMP) - The Central Coast Regional Water Quality Control Board (Region 3) monitors for CECs in surface water as part of its regionally scaled water quality monitoring and assessment program. CCAMP monitoring is conducted through coordinated implementation of the Surface Water Ambient Monitoring Program (SWAMP), including the Stream Pollutant Trends assessment program (SPoT) and the Freshwater CyanoHABs Program. Monitoring is implemented based on permit requirements and collaborative efforts with the Cooperative Monitoring Program for Agriculture, the City of Salinas, and the Central Coast Long-Term Environmental Assessment (CCLEAN) program, a discharger-funded monitoring program assessing loading of pollutants from stream, river, and effluent discharges and associated impacts the nearshore environment. CCAMP has also partnered with agencies such as the California Department of Pesticide Regulation (DPR) and the United State Geological Survey (USGS) to focus on high priority areas within the region. Additional information is available in the Region 3 SWAMP Factsheet and data is posted using an interactive tool, the CCAMP Data Navigator.

CCAMP intermittently conducts additional special studies that include extra pesticide chemistry analysis to support TMDL development and provide follow up monitoring. More information about this program is available at the Water Board’s GAP program webpage.

Region 3 coordinates with the statewide Bioaccumulation Oversight Group (BOG) to fund additional sample collection and tissue analysis of fish and shellfish in nearshore areas and lakes in the central coast. More information on these activities can be found on the Water Board’s Bioaccumulation Monitoring Program webpage.

Delta Regional Monitoring Program (DRMP) – In coordination with the State Water Board, the Central Valley Regional Water Board, and the San Francisco Bay Water Board, developed a regional monitoring program in the Delta.  The DRMP includes a multi-year study (started in 2018) of current-use pesticides and aquatic toxicity in the Sacramento-San Joaquin Delta. Other studies include nutrients, mercury, pathogens, and CECs.

San Francisco Bay Regional Monitoring Program (SF Bay RMP) - The San Francisco Bay Regional Water Board have investigated the occurrence and potential adverse impacts due to CECs since 2001 through this discharger-funded program. This program is partnership with combined financial support, direction, and participation by the San Francisco Bay Regional Water Board, the San Francisco Estuary Institute (administrator), and regulated dischargers in the San Francisco Bay.

Santa Ana Watershed Project Authority (SAWPA) convened a CEC Workgroup, consisting of the Santa Ana Regional Water Quality Control Board and various water supply and wastewater agencies throughout the Region.
