Phosphorus pollution is a growing problem in aquatic ecosystems. The Massachusetts MS4 General Permit regulates the amount of phosphorus pollution in water. The goal of this project was to determine if Tyngsborough was contributing to elevated phosphorus levels in the Merrimack River and, in collaboration with the Tyngsborough Conservation Commission, design a plan to reduce phosphorus levels in accordance with the permit. Structural, non-structural, and low impact development (LID) best management practices (BMPs) were analyzed. The final design is a combination of non-structural and LID BMPs. By implementing these strategies, Tyngsborough can begin the process of reducing phosphorus pollution.
