The plant's treated effluent enters the Passaic River watershed, a major drainage system in northern New Jersey. The Passaic River flows through urban and suburban areas before reaching Newark Bay, an estuary that supports migratory fish and bird species. Downstream, the bay connects to the Atlantic Ocean, making nutrient and pollutant management critical for coastal water quality.
