Impoundments and lake systems become eutrophic through excessive nutrient (phosphorus and nitrogen) loadings. Deterioration of water quality because of algal blooms has forced many water quality control boards to adopt measures to reduce discharge of such nutrients into the water bodies. Phosphorus is the nutrient that is selected most frequently for control as there are fewer pathways for it to enter a lake than there are for nitrogen. For instance, the Virginia Water Control Board has adopted an average monthly limit of 2 mg/1 of total phosphorus in the effluent of about forty wastewater treatment plants in the Chesapeake Bay Drainage Basin [1].
