At the request of the Central Valley Regional Water Quality Control Board, the Delta Science Program has completed a two-part review of the characterization and control studies associated with the Delta Mercury Control Program. The purpose of the review was to evaluate the results, conclusions, and completeness of each study.
Two sets of studies were reviewed by an independent panel of experts in mercury cycling, wetland ecology, and modeling.
Part one of the review, completed in August 2019, assessed urban stormwater and wastewater mercury control studies.
Part two of the review, completed in July 2021, assessed two studies on mercury dynamics in tidal wetlands and modeling of open water mercury dynamics in the Sacramento-San Joaquin Delta.
