For plants serving this population size, secondary treatment is the minimum standard, with potential additional nutrient removal requirements due to the sensitive coastal environment. The plant is located within 50 km of the Atlantic coast, with treated effluent likely discharging into local waterways that drain to Delaware Bay or the Atlantic Ocean. This coastal proximity means the plant's discharge can affect sensitive estuarine and marine ecosystems, including shellfish habitats and migratory fish populations.

Wolfe Neck STP is situated in coastal Delaware, with treated effluent likely entering tributaries of the Delaware Bay or directly into Atlantic coastal waters. The Delaware Bay is a major estuary supporting diverse aquatic life, including horseshoe crabs and migratory shorebirds. The plant's discharge must meet stringent nutrient limits to prevent eutrophication in these sensitive coastal waters.
