Sewage problem in Great Lakes

Nov/06: Ontario and American cities around the Great Lakes are failing to keep sewage out of the Great Lakes, suggests a study by the Sierra Legal Defence Fund, a Canadian environmental group. The Great Lakes, one of the world's most important freshwater ecosystems, provides drinking water for millions. Windsor had the worst record on the Canadian side. Sudbury, Kingston, Hamilton, Sarnia, Toronto and the Niagara Region rated below-average. Kitchener-Waterloo, York and Durham regions refused to participate. The main culprit for Canadian cities was the frequency of sewer overflows due to antiquated systems.
