SHAMOKIN TWP STP - Shamokin Township, Pennsylvania Wastewater Treatment Plant

SHAMOKIN TWP STP is a municipal wastewater treatment facility located in Shamokin Township, Northumberland County, Pennsylvania. It serves a small population of 100 residents, reflecting its role as a local-scale plant in a rural area of the Susquehanna River basin. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal facilities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 53.00 units, and it currently discharges 37.85 units, indicating operational headroom. The treated effluent is discharged into a local waterway that ultimately drains into the Susquehanna River and then to the Chesapeake Bay. As part of the Chesapeake Bay watershed, the plant contributes to regional nutrient management efforts aimed at reducing nitrogen and phosphorus loads to the estuary.

The plant discharges into a tributary of the Susquehanna River, which flows 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. Nutrient pollution from wastewater is a key concern, and plants like SHAMOKIN TWP STP are subject to EPA and state regulations to limit nitrogen and phosphorus discharges.
