Headwater Mercury Source Reduction Workshop, Fall 2020:
November 12, 2020, Held Virtually via Zoom
The HMSR, Fall 2020 Implementation Workshop will include a day of technical presentations and a virtual tour visiting projects to address the issue of mercury contamination in Sierra waterbodies and the associated issue of mercury in locally caught fish. Two of TSF’s four strategic targets for addressing headwater sources of mercury will be explored at the Workshop:
- Mercury-Contaminated Sediment in Reservoirs: Sediment transported off of hydraulic mines is captured behind reservoirs, necessitating ongoing maintenance. Sediment can take up valuable water storage space in reservoirs and cause water quality impacts. Best available technologies to address reservoir sedimentation and remove mercury-contaminated sediment from reservoirs will be discussed and statewide applicability of approaches debated.
- Mercury Exposure via Fish Consumption: Consumption of contaminated fish is the primary pathway of human exposure to the neurotoxin methylmercury. In 2020 AB 762 was signed into law, representing the most significant step toward protecting public health from contaminated fish to date. AB 762 requires the posting of state-issued site-specific fish consumption advisories at water bodies where they apply. The opportunities and challenges of this new law will be debated by state public health experts and county-level staff charged with implementation.
