Background

The 150-acre Sulphur Bank Mercury Mine site is located in Clear Lake, California. Former mining activities at the site contaminated soils, sediments and surface water with mercury and arsenic. The site also includes the Elem Tribal Colony residential area and the Herman Impoundment, a flooded open pit mine. Following immediate actions to protect human health and the environment, site investigations and long-term cleanup planning are ongoing.
