Mercury Removal Project

Most surface waters in the Sierra Nevada have been significantly and adversely impacted by historic gold mining activities, particularly the streams, rivers, and reservoirs in the Cosumnes, American, Bear and Yuba watersheds. As a result, water bodies in these regions contain elevated concentrations of mercury that are remnants of gold processing practices used over a century ago. Mercury is a water quality constituent of national concern; it is listed in California Toxics Rule by the Environmental Protection Agency. Consumption of fish from water bodies contaminated with mercury can lead to developmental delays in fetuses, infants and children
