Falmouth WWTF discharges into the Presumpscot River, which flows into Casco Bay, a semi-enclosed estuary on the Gulf of Maine. Casco Bay is ecologically sensitive, supporting eelgrass beds, lobster populations, and seabird colonies. The bay's health depends on controlling nutrient loads from wastewater to prevent algal blooms and hypoxia.
