Environmental impact of the Contact and Sonoma mercury mines on water, sediment, and biota in Anna Belcher and Little Sulphur Creek watersheds, Sonoma County, California [New Window]: Data from field sampling of tailings, waste rock, sediment, and water at the mines, along with water, sediment, and biota in a pond and tributaries that drain from the mine area, to help assess the chemical hazards due to historic mining.
Environmental impact of the Helen, Research, and Chicago mercury mines on water, sediment, and biota in the Upper Dry Creek watershed, Lake County, California [New Window]: Data from field sampling of tailings, waste rock, sediment, and water at the mines, along with water, sediment, and biota in a pond and tributaries that drain from the mine area, to help assess the chemical hazards due to historic mining.
Impact of mine and natural sources of mercury on water, sediment, and biota in Harley Gulch adjacent to the Abbott-Turkey Run mine, Lake County, California [New Window]: Detailed samples around these abandoned mines will help to determine how well site remediation efforts have worked to reduce the dangerous levels of mercury that come from both natural sources here as well as the abandoned mines.
Mercury geochemistry of gold placer tailings, sediments, bedrock, and waters in the lower Clear Creek area, Shasta County, California; report of investigations, 2001-2003 [New Window]: Total mercury and methylmercury measured in sediments, tailings, and water in an area where historical gold mining has occurred; proposed habitat restoration work may release some of the mercury that is currently buried there.
Mercury release from the Rathburn Mine, Petray Mine, and Bear Valley saline springs, Colusa County, California 2004-2006 [New Window]: Summary of data obtained from field sampling of mine tailings and waste rock and water and sediment in regional springs and tributaries that drain from the mine area into Bear Creek. Ground-water springs are also potential sources of mercury here.
Review of samples of water, sediment, tailings, and biota at the Little Bonanza mercury mine, San Luis Obispo County, California [New Window]: Data from field sampling of mine tailings, wasterock, sediment, water, and biota at the mine in 2010. Results permit a preliminary assessment of the mining sources of Hg and associated chemicals that could produce elevated levels of monomethylmercury.
Bedrock and soil geochemistry from Voyageurs National Park, Minnesota [New Window]: Analyses to establish the background and baseline geochemistry for bedrock and soil in the region, and to determine terrestrial mercury sources and sinks in the park
