Potomac Leads Most Endangered Rivers List
By John Cronin
The Potomac River topped the list of most endangered rivers in the nation, published by American Rivers on April 15. The Potomac’s condition epitomizes the struggle for success in which the 1972 Clean Water Act is still engaged on its 40th anniversary. Flowing through the heart of Washington DC
just two miles from Capitol Hill, a source of drinking water for Congress, the Potomac has been the shame of the nation since at least 1965, when President Lyndon Johnson declared it “a national disgrace.”
A 2010 evaluation of the Potomac River by the University of Maryland gave the river a “D” as part of its overall evaluation of the Chesapeake Bay system, which earned a “C-”. There is no indication that the river’s quality has improved since. The Potomac’s headwaters are in Fairfax Stone, West Virginia. From there it runs 383 miles to Point Lookout, Maryland. Its watershed encompasses 14,670 square miles, and also includes Pennsylvania and West Virginia.
American Rivers describes the Potomac’s condition:
The Potomac is the ‘nation’s river,’ rich in culture and history and the lifeblood of our nation’s capital. The river provides drinking water to more than five million people and offers abundant opportunities for recreation. However, the Potomac is threatened by agricultural and urban pollution . . .Pollution in the Potomac threatens drinking water supplies, kills fish, and poses a health risk to people who swim, fish, and boat on the river.
American Rivers gets it right when it says that rollbacks to the Clean Water Act will make matters worse on the Potomac and other waters. But does that mean the law as currently written has the right stuff to “restore and maintain the chemical, physical and biological integrity of the nation’s waters,” as Section 101 of the Act aspires to do? => More…
