From the State Water Resources Control Board:
The State Water Board and Ocean Protection Council funded a grant to reconvene the Constituents of Emerging Concern (CEC) Science Advisory Panel for Aquatic Ecosystems (Panel) to assess the current state of scientific knowledge on the risks of CECs impacting human health and the environment in freshwater, coastal, and marine ecosystems of the state and update their 2012 recommendations.
Division of Water Quality staff in collaboration with the regional water boards and Aquatic Science Center compiled a statewide geospatial CEC dataset with over 450,000 records. The Panel conducted a critical review of the CEC dataset and worked with Division of Water Quality staff to make refinements to improve the quality, utility, and representativeness of the data. The Panel compiled, reviewed, and interpreted data to inform an updated risk screening approach and an initial prioritization of CEC compounds of interest.
The Panel’s updated recommendations are published in a document titled, Draft Final Report, Monitoring Strategies for Constituents of Emerging Concern (CECs) in California’s Aquatic Ecosystems, Recommendations of a Science Advisory Panel, dated November 23, 2022.
The CEC Aquatic Ecosystems Panel will provide a final report-out to the public with their recommendations via a Zoom webinar hosted by Southern California Coastal Water Research Project (SCCWRP). The webinar will be held on December 12, 2022 from 8:00 to 10:30 AM Pacific Time (US and Canada). The webinar is free and open to the public.
