The U.S. Environmental Protection Agency announced recently that the Ashtabula River has been removed from the binational list of the Great Lakes’ most environmentally degraded areas after decades of work.
In the 1980s, the United States and Canada identified 43 “Areas of Concern” on the Great Lakes affected by historical contamination dating back over many decades. The Ashtabula River is the sixth AOC to be delisted in the United States and first of four in Ohio.
