Our purpose is to inform the public and decision makers about environmental issues so that the best choices can be made for a sustainable high quality of life for present and future Mariposans as change comes to our community. Our environment and our economy are intimately linked as in most Sierran counties. The underlying principles of MERG are to inform and educate the community as to issues that affect our environment, to conduct scientific research within our capabilities in furtherance of our education and information mission, and to observe and report on local government issues, efficiency, and effectiveness. The fact, the project was a major environmental and health threat.



MERG was incorporated in 1989 for the purpose of gathering and disseminating information about an open pit, cyanide heap leach mine with cyanide roaster proposed for Mariposa County. When the facts became known, it was clear that this project was a major environmental and health threat. It did not go forward, but MERG did, continuing to evaluate other projects and issues. MERG seeks to lay out the pros and cons of issues so that county residents can make informed decisions about their future. This is done through our website, our newsletter, and public news media as may be appropriate.



Some of the more significant undertakings of MERG have been implementation of the Brown Act at Supervisors' meetings, evaluation of the risks and benefits of a redevelopment proposal, fact finding on Clean Water Grant project reform of the 1872 Mining Law, sponsorship of the Foothill Mining Conference, publicizing the unmitigatable environmental impacts of a large development project, advocating Wild and Scenic status for the Merced River, making recommendations in regard to industrial zoning in the County, encouraging our Supervisors to follow CEQA in this process, and successful litigation with the National Park Service to force the production of the twelve year overdue Merced River Plan.
