Mining’s Toxic Legacy: An Initiative to Address Mining Toxins in the Sierra Nevada

The Sierra Fund (Sierra Fund) | March 1st, 2008


The purpose of this report is to present current information on the nature and extent of mining toxins in the Sierra, the problems they pose to human and environmental health, and recommendations for action to address these problems. This is accomplished by examining the best available science from the perspective of communities in the Gold Country, and directing the results to regional nonprofit organizations and local, state, federal, and tribal governments.

The area considered by this Initiative is defined to be consistent with the State of California’s Sierra Nevada Conservancy service boundary. Areas of the Sierra Nevada in the State of Nevada were also considered as a secondary topic. This enabled the Initiative to address both the east and west sides of the Sierra, as well as some parts of the Cascade region, all of which were heavily impacted by historic mining.

Though the impact of gold mining is the primary focus of the Initiative, gold prospectors found other commodities, including iron, copper, lead, silver, and tungsten which they then mined and sold. This report considers the impact of these mining activities as a secondary topic and in less detail.
