The first phase of the Delta Mercury Control Program required discharging entities to develop characterization and control studies to evaluate approaches for managing methylmercury.

• Phase 1 Methylmercury Characterization and Control Study Final Reports are listed on the Archived Documents webpage.

The Central Valley Water Board requested the Delta Science Program coordinate and conduct an independent review of these studies to assess the scientific validity of methods, analyses, and conclusions.
