#9 Monongahela River, Pennsylvania and West Virginia
Threat: Natural Gas Extraction
The Monongahela River provides drinking water for hundreds of thousands of people, and is home to some of the East Coast’s best fishing, whitewater boating, and wildlife.
However, the river and its clean water are threatened by pollution created by natural gas extraction activities in the Marcellus Shale.
The Ohio River Valley Water Sanitation Commission, and the states of Pennsylvania and West Virginia, must act to prohibit water quality degradation associated with Marcellus Shale drilling to protect the region’s clean water for future generations.
