The brochure was created as a follow up to The Sierra Fund’s two studies on human exposure to legacy mining toxins.
The widespread distribution of toxins associated with the Gold Rush, including mercury, arsenic and lead, constitutes the oldest and longest neglected environmental problem in the State of California.
Since 2006, The Sierra Fund has worked to address the ongoing human health, cultural and environmental impacts of historic mining in the Sierra Nevada.
High levels of arsenic, lead and asbestos can be found at old mine sites. These materials are known to cause serious health problems including cancer, heart disease, and child development problems.
