Elkton WWTP - Wastewater Treatment Plant in Elkton, Maryland, USA

Elkton WWTP is a municipal wastewater treatment facility located in Elkton, Cecil County, Maryland, serving a population of about 13,750. The plant is situated near the headwaters of the Chesapeake Bay, one of the largest and most productive estuaries in the United States. As a US facility, Elkton WWTP operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which is part of the Clean Water Act. For a plant serving a population of this scale, secondary treatment is typically required, with additional nutrient removal standards applicable in the Chesapeake Bay watershed to address eutrophication. The plant discharges into local waterways that ultimately drain into the Chesapeake Bay. The Bay ecosystem supports diverse aquatic life, including blue crabs, oysters, and migratory fish, and is a critical habitat for waterfowl. Nutrient pollution from wastewater is a key concern in this region, driving stringent permit limits.

Elkton WWTP discharges into tributaries of the Chesapeake Bay, the largest estuary in the United States. The Bay watershed spans six states and supports a complex ecosystem of wetlands, submerged aquatic vegetation, and fisheries. Nutrient loading from wastewater contributes to algal blooms and hypoxic zones, making advanced treatment important for Bay health.
