Recovery of the Laurentian Great Lakes, 1970-1985 : eutrophication aspects / J.M. Barica.: En13-5/88-44E-PDF
"Eutrophication of the Laurentian Great Lakes accelerated exponentially during the first half of this century. Canada and the United States recognized this fact and signed the 1972 Great Lakes Water Quality Agreement. Since then, coordinated activities have resulted in a massive cleanup, unprecedented in history. Major wastewater treatment programs have been implemented. With expenditures totaling over eight billion dollars, industrial controls and phosphate limitations in detergents produced a reduction and even a reversal of the eutrophication process. The long-term trend of total phosphorus concentrations have been downward since the mid 70's when legislation on phosphorus reduction was put into effect. Nuisance algal blooms are no longer a common occurrence and Cladophora infestations of nearshore areas are declining"--Abstract.
