A Phosphorus Management Lp Model Case Study1

Abstract

A linear programming model to assess the cost‐effectiveness of appropriate point and nonpoint phosphorus control measures was constructed for Carnegie Lake, an eutrophic lake located in Mercer County, New Jersey. The resultant model was tested for present and future conditions. Feasible solutions were obtained only after significant relaxation of receiving water quality standards. The high levels of point source treatment required to meet the in‐stream water quality standards and the mesotrophic loading conditions suggest that a source control solution may not be feasible.
