| Abstract |
Data collected as part of the National Eutrophication Survey (NES) were used to test the consequences of eight different phosphorus control options. The control options included detergent limitations, municipal treatment plant control, nonpoint source control and combinations of tertiary sewage treatment and nonpoint source control. The results indicated that although site specific studies should be conducted for any given lake, as a general rule detergent phosphorus control would be of marginal value. A combination of municipal control and a sixty percent reduction in nonpoint sources would reduce average lake phosphorus concentration from 0.084 mg/l to 0.029 mg/l. It was found that nonpoint source control was more effective in increasing the number of lakes with less than 0.025 mg/l of total phosphorus than was an equivalent level of point source control. |
