EPA Reports Almost Half of the Nation’s Streams Are Polluted

“The draft Wadeable Streams Assessment: A Collaborative Survey of the Nation’s Streams (WSA) is a first-ever statistically-valid study of the biological condition of small streams throughout the U.S. It establishes a national baseline we can use to compare to results from future studies. This information will help us evaluate the successes of our national efforts to protect and restore water quality. The draft WSA is available for public review and comment [until June 30, 2006].”

  • Wadeable Streams Assessment: A Collaborative Survey of the Nation’s Streams, EPA 841-B-06-002 April 2006 – The assessment “found that 28% of U.S. stream miles are in good condition compared to the best available reference sites in their region, 25% are in fair condition, and 42% are in poor condition.
