WESTFIELD BORO STP - Advanced Wastewater Treatment in Westfield Township, Pennsylvania

WESTFIELD BORO STP is a municipal wastewater treatment facility located in Westfield Township, Tioga County, Pennsylvania. The plant serves a small community of approximately 1,393 residents, providing advanced treatment to protect local water quality. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For small agglomerations like this, advanced treatment goes beyond secondary standards, often targeting nutrient removal or other specific pollutants to meet water quality goals. The treated effluent is discharged into a local water body within the Susquehanna River basin, which ultimately drains to the Chesapeake Bay. This makes the plant's advanced treatment particularly important for reducing nutrient loads that contribute to eutrophication in the bay ecosystem.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is a large estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater is a key concern, and advanced treatment helps reduce nitrogen and phosphorus loads that can cause harmful algal blooms and hypoxia in the bay.
