The plant's treated effluent enters local streams within the Delaware River watershed, flowing into the Delaware River and eventually the Delaware Bay and Atlantic Ocean. The Delaware River supports diverse aquatic life, including migratory fish species, and provides drinking water for millions. Protecting this watershed from nutrient pollution and pathogens is critical for ecological health and human use.
