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 Upper Delaware River found itself at #1 on the Most Endangered Rivers List. The Upper Delaware River provides drinking water to 17 million people across Pennsylvania and New York. However, this clean water source is threatened by natural gas extraction activities in the Marcellus Shale, where chemicals injected into the ground create untreatable toxic wastewater. Until a thorough study of these critical impacts is completed, the Delaware River Basin Commission must not issue permits that will allow gas drilling in this watershed. In addition, Congress must pass the Fracturing Responsibility and Awareness of Chemicals Act of 2009 to help protect all rivers within the Marcellus Shale region.
