The Mercury Monitoring and Evaluation Section was created in 2012, after the Delta Mercury Control Program was adopted by the Central Valley Regional Water Quality Control Board. This section ensures DWR's compliance with mercury and methylmercury related regulations in California. This includes designing and implementing water quality studies, aggregating and analyzing data, and serving as an information resource for DWR staff working on projects with a mercury component.
