| 520 | 3 |a"The experience in controlling nutrient pollution in the Great Lakes was generally positive. Scientific predictions about the degree of phosphorus load. reduction needed were mostly accurate. Simple technologies of phosphorus precipitation and replacement of detergent phosphorus were successful. Enhanced technologies of sewage plant optimization and perhaps filtration will be needed in some areas to maximize restoration. Non-point source nutrient control has been largely driven by economics and is still a large problem. Restoration of embayments and harbours requires very stringent nutrient control. The concentration of agricultural waste from industrial type feedlots is a growing concern. The control of eutrophication appears to be an ongoing problem well into the future"--Abstract. |
