Coal Mining

Over the past 20 years, Mountain Watershed has raised almost $9 million dollars to create mine drainage treatment systems that remove harmful pollutants and have helped to restore the water and hence, quality of life, in our region.

Currently, one of the greatest threats to the health of the watersheds and quality of life in the Appalachian region is industrial resource extraction, primarily the development of shale gas, coal, and petrochemical infrastructure. The Direct Support Fund provides small grants to grassroots groups and advocates working toward social change on any of these environmental justice issues and more.


A Year in the Yough

Quality of life in the Laurel Highlands region depends on the Youghiogheny River and tributaries like Indian Creek. Our streams are a source of recreation, tourism, sustainable economic growth, and drinking water. As citizens, it is our duty to protect these resources.

We hold polluters and environmental regulators accountable to ensure protection of our communities and the environment.
