The Primer answers three key questions: What are the modern-day effects of historic mining in the Sierra Nevada? Why do nonprofit organizations need to be aware of these impacts? What can nonprofits do to respond to legacy mining hazards in their communities?
Many California land trusts own property contaminated with legacy mine wastes or physical hazards. Other nonprofit organizations may encounter mining toxins during restoration projects such as development of wetlands, building trails, or restoring streams on public lands. Legacy mining toxins can include mercury, asbestos, chromium, lead, acid mine drainage and more.
