America may be filled with beautiful rivers and streams, but some of the country's most notable waterways are also its most endangered. Released Tuesday, the 2012 America’s Most Endangered Rivers list examines the most threatened waterways in the U.S. and the human activities that jeopardize their quality.
American Rivers president Bob Irvin said in a statement that the list, "underscores how important clean water is to our drinking water, health, and economy. If Congress slashes clean water protections, more Americans will get sick and communities and businesses will suffer.
Several rivers on the list -- in Wyoming, Ohio and West Virginia -- are threatened by natural resource extraction, including natural gas development and mountaintop removal coal mining.
The report argues that to protect northeastern Ohio's Grand River from negative impacts of natural gas development, the state must "require the highest standards" for monitoring and testing chemicals and wastewater related to fracking.
