CRISFIELD WWTP: Crisfield, Maryland Wastewater Treatment Plant

CRISFIELD WWTP is a municipal wastewater treatment facility serving the community of Crisfield, Maryland, in Somerset County. The plant serves a population of approximately 5,200 people, reflecting a small to medium-sized agglomeration typical of coastal towns in the region. As a U.S. facility, the plant operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment. For plants of this scale, secondary treatment is the federal minimum standard, though more advanced treatment may be required to protect sensitive coastal waters. The plant's treated effluent ultimately reaches the Chesapeake Bay, the largest estuary in the United States. The bay supports diverse aquatic life, including blue crabs, oysters, and migratory fish, making nutrient removal a critical concern for wastewater facilities in this watershed.

CRISFIELD WWTP discharges into the Chesapeake Bay watershed, which drains into the Atlantic Ocean. The Chesapeake Bay is a highly productive estuary that supports extensive fisheries and provides critical habitat for migratory birds. Nutrient loading from wastewater is a key environmental concern, as excess nitrogen and phosphorus can contribute to algal blooms and hypoxic zones in the bay.
