Each year since 1986, American Rivers has released its America's Most Endangered Rivers report to spotlight the nation's ten most imperiled rivers. This year, the Monongahela River found itself at #9 on the Most Endangered Rivers list. 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 protect the region's clean water for future generations by prohibiting water quality degradation associated with Marcellus Shale drilling.
