America's 10 Most Endangered Rivers

"The Colorado River, confronting mounting problems with radioactive, toxic, and human waste, topped this year's list of ten rivers. It supplies the water for 25 million people, including residents of Los Angeles and Las Vegas...America's waters became progressively cleaner for decades after Congress passed the Clean Water Act in 1972, but recent monitoring data indicates that this trend has reversed itself...the administration has reduced the number of Clean Water Act enforcement actions, levied fewer and smaller fines on lawbreakers, and created new loopholes on behalf of polluting industries."
