...growing pollution of the Great Lakes was not only an aesthetic and commercial tragedy. More than 29 million Americans and 9 million Canadians (more than a third of Canada's population) live in the Great Lakes basin. The lakes contain 95% of the U.S. supply of fresh water in lakes and reservoirs and 20% of the world's; they supply drinking water for 23.5 million Americans. Clearly, something had to be done...
...past decade, international commissions have been formed, endless stacks of reports written, legislation passed, bans enforced, and billions of dollars spent on facilities to clean the waste water that was being dumped into the lakes. As a result, even environmentalists are optimistic about the future of the waters. Says G. Keith Rogers, a scientist at the Canada Center for Inland Waters: "Previously people were saying 'How can we stop the lakes from getting worse?' Now we are seriously talking about rehabilitating the lakes to their original state...
...work has been accomplished. The globs of oil, the multicolored industrial discharges, the flotsam from shoreline cities, the fecal and bacterial wastes are no longer dumped in the lakes in vast quantities. According to the International Joint Commission, the group overseeing the U.S.-Canadian agreements to clean up the waters, more than 600 of the 864 major dischargers into the Great Lakes now meet the tough new water-quality regulations. In the past ten years U.S. and Canadian municipalities have spent more than $5 billion to improve sewage treatment plants. Industries, often prod! ded by injunctions and fines, have spent...
...most important omens for the future of the lakes is the sharp reduction in the amount of phosphorus dumped into them. A 1972 U.S.-Canadian agreement lowered the levels of phosphates that municipalities were allowed to dump into the water, and most towns along the shores and on rivers emptying into the lakes are well on their way toward meeting those requirements. The significant exception is the city of Detroit; it continues to dump three times the permissible levels into the Detroit River, which flows into the western end of Lake Erie. One of the largest sources of the harmful...
...learn more about the problems of he Great Lakes, we discover that it's not as easy as it first appeared when we assumed that if we'd just get industry and the municipalities to clean up their acts, we'd have clean water. Now we've largely done that, and we discover that there are dangerous toxic substances in the lakes we didn't even know about before...
