NOAA: Great Lakes on road to recovery

Efforts to improve the quality of Great Lakes waters may show results sooner than expected, and Lake Ontario, at least, is already healthier than it was a few years ago, according to a scientist with the National Oceanic and Atmospheric Administration (NOAA).

Results from a computer model indicate that the largest lakes could show decreasing loads of pollutant phosphorous in several decades—a tenth of the time predicted in earlier calculations—and Lake Erie could show such improvement in less than a year. The calculations were made by Steven Chapra of NOAA's Great Lakes Environmental Research Laboratory in Ann Arbor, Mich., using a model that simulates the effects of pollutant phosphorous in the lakes and predicts the results of pollution abatement efforts.
