The Massachusetts Estuaries Project and Reports

Many people know that nutrients like phosphorus and nitrogen are contained in fertilizers, and when overused can cause water pollution problems that require corrective action. But the impacts of excessive nutrient pollution to coastal communities from wastewater disposal systems and storm water runoff are not understood as well. The Massachusetts Estuaries Project was developed to determine current nutrient loads and assist in the evaluation of future nutrient load scenarios for estuaries located in Southeastern Massachusetts coastal communities.
