A simplified mathematical model of a lake system indicates that, if the pollution of the Great Lakes were discontinued, the natural flow through the lower Great Lakes would be sufficient to remove about 90 per cent of the waste in about 20 years. On the other hand, hundreds of years would be required to displace the pol lution from Lake Michigan and Lake Superior.
