During heavy rains, raw sewage from old, leaky, combined sewer-stormwater systems is often flushed into the Great Lakes, resulting in beach closures not fun for tourists. At the same time, in Cleveland, Ohio; Buffalo, New York; and Gary, Indiana?where populations have declined by as much as 40 to 50 percent since the 1950s?derelict houses and vacant lots have increased: 30,000 in Cleveland, 7,000 in Gary, and more than 6,000 in Buffalo. Cleveland, Buffalo, and Gary are among 158 communities with permits from the Environmental Protection Agency (EPA) to discharge treated wastewater into the Great Lakes. The agency has also charged them with implementing Long Term Control Plans under the Clean Water Act to eliminate discharges of untreated sewage from their combined system overflows. ?It?s a funny thing,? says David Rankin, the executive director of the Great Lakes Protection Fund, a private nonprofit corporation that funds projects to build the health of the lakes. ?Most of the time these systems do a great job of managing stormwater?they actually treat ...
