Several recommendations are made by the IJC Water Quality Board. Improve reporting of point source discharges of phosphorus to the Great Lakes. Improve procedures for assessing whether the phosphorus target loads specified in the 1978 Water Quality Agreement are being met. Improve sampling of key tributaries so the reliable phosphorus loading estimates are obtained. Implement legislation in Canada to reduce the content of phosphorus in laundry detergents to 0.5 percent by weight as phosphorus.
Parties meet to review the effectiveness of phosphate control programs.
Reducing the phosphorus target loads for Lake Erie over a period of years should result in desirable water quality conditions for Lake Erie aquatic life. The target load is a long-term goal that must be met or exceeded for a period of years before the desired lake conditions will be achieved.
