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

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.

Info
Environmental impact of the Helen, Research, and Chicago mercury mines on water, sediment, and biota in the Upper Dry Creek watershed, Lake County, California

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.

Info
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

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.

Info
Review of samples of sediment, tailings, and waters adjacent to the Cactus Queen gold mine, Kern County, California

Mine tailings here have high levels of arsenic. Experiments conducted on these sediments indicate that the arsenic can be released into the environment and become hazardous through chemical processes that occur when fine sediment is ingested by animals.

Info
Review of samples of tailings, soils and stream sediment adjacent to and downstream from the Ruth Mine, Inyo County, California

Detailed study of mine waste material and sediments from streams passing through it. Arsenic is the main contaminant of interest here.

Info
Review of samples of water, sediment, tailings, and biota at the Little Bonanza mercury mine, San Luis Obispo County, California

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.

Info
Mercury geochemistry of gold placer tailings, sediments, bedrock, and waters in the lower Clear Creek area, Shasta County, California; report of investigations, 2001-2003

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.

Info
Mercury release from the Rathburn Mine, Petray Mine, and Bear Valley saline springs, Colusa County, California 2004-2006

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.

Info
Geologic map of the Bodie Hills, California and Nevada

Spatial geologic map with rock type, vents, arcs, landslides, etc. provided in an ESRI geodatabase and KMZ format for Google Earth viewing. Mapsheet with accompanying descriptive pamphlet is provided as a PDF. Petrographic rock summary is also included.
