Report shows half of U.S. waterways don't meet Clean Water Act standards, 50 years later

It's been 50 years since the landmark environmental law, the Clean Water Act, was passed in 1972. It was an ambitious piece of legislation, and it made a real difference in some of the most polluted waterways in the U.S. But a new report from the Environmental Integrity Project shows that half a century later, the promises of the Clean Water Act have only been half kept.

Their research ranked Oregon as #2 in the U.S. for the most miles of rivers and waterways that aren't safe for swimming or recreation. 

Eric Shaeffer is the Executive Director of the Environmental Integrity Project and co-author of the report, "The Clean Water Act at 50: Promises Half Kept at the Half Century Mark." KBOO's Althea Billings reports.
