Poplar Hill Wastewater Treatment Plant, Royal Oak, Maryland

Poplar Hill is a wastewater treatment plant located in Royal Oak, Maryland, United States. It serves a small population of 250 residents in the rural area of Wicomico County. The plant operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for all discharges. The plant provides primary treatment, which involves physical sedimentation to remove settleable solids. Its designed capacity is 113.56 million gallons per year, with an actual discharge volume of 90.85 million gallons per year. As a small facility, it is subject to state and federal regulations that ensure basic pollutant removal. The treated effluent is discharged into local waterways that ultimately flow into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Protecting this ecosystem requires effective wastewater management to reduce nutrient and sediment loads.

Poplar Hill discharges into the Chesapeake Bay watershed, which drains into the Atlantic Ocean. The bay is an ecologically sensitive estuary that supports diverse aquatic life, including spawning grounds for fish and habitat for shellfish. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making treatment important for bay health.
