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. |

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. |
