"Potomac River Threatened by Pollution, Congress, New Report Says"
"A new report named the Potomac the nation’s most endangered river, saying it is threatened by nutrient and sediment pollution that lowers the quality of drinking water and kills marine life and will only get worse if Congress rolls back regulations in the Clean Water Act."
"'America’s Most Endangered Rivers,' the annual report from the nonprofit advocacy group American Rivers, is to be released early Tuesday. It notes what local friends of the Potomac have said for years: that urban development is funneling tons of polluted rainwater to the river, that chemical fertilizer and manure from farms make matters worse, and that wastewater overflowing from sewers, along with pharmaceuticals flushed down toilets, contribute to dead zones in which marine life dies and might cause fish to switch sexes. Some male fish in the river mysteriously have eggs.
Just as troubling, said American Rivers President Bob Irvin, is a range of proposals by House Republicans to strike various provisions from the Clean Water Act as it nears its 40th anniversary in October."
