Environmental Health Outreach

The goal of The Sierra Fund’s Health Outreach Program is to conduct public outreach and education to help people take action to protect themselves, their families and their communities from exposure to legacy mining toxins.

In particular, our program covers reducing exposure to:

  1. Mercury which was widely used in historic gold mining throughout the Sierra Nevada and which today is present at high levels in certain kinds of fish; and
  2. Lead, Arsenic and Asbestos, which are naturally occurring in Sierra Nevada rocks but which can pose an exposure hazard at historic mine sites where these rocks were finely crushed and left spread over the surface.

The current phase of our program, which began in 2012, includes multiple activities.  Click the links to read more about each component:

  • Trainings for doctors and clinic staff about the presence of mercury in locally caught and commercial fish, and its danger to sensitive populations. Presentations range from 15 minutes to one hour depending on the desires of the clinic.
  • Community Meetings in historic mining towns
  • Posting state-issued Fish Consumption Advisories at popular fishing locations
  • Holding collaborative meetings with community leaders and health professionals in historic mining towns and in the downstream communities that serve them
  • Hosting a bi-annual conference on “Reclaiming the Sierra”
  • Tabling and conducting outreach at events
  • Communications through an online and print media campaign focused on providing accurate and detailed information on historic mercury use and how it impacts local fisheries.


Since 2006, The Sierra Fund has conducted a program to educate Sierra residents and the medical professionals who serve them about the environmental health hazards that result from exposure to historic mining toxins, which are found in locally caught fish and in dust near abandoned mine sites.

Our work is informed by numerous peer-reviewed scientific and medical studies, and our public outreach materials are reviewed by our Working Group of technical advisors.  In addition to general research on mercury, arsenic, lead and other toxins resulting from historic mining, in 2009-2011 The Sierra Fund conducted two studies to learn whether exposure pathways to these toxins existed in the Sierra:

Our job is to get the information we have now documented about the danger of eating certain species of locally caught fish – known to be contaminated from legacy mercury from gold mining – into the hands and minds of women, children and their care givers.
