Bloomsburg STP | Wastewater Treatment Plant in Bloomsburg, Pennsylvania

Bloomsburg STP is a municipal wastewater treatment facility located in Bloomsburg, Columbia County, Pennsylvania. It serves a population of about 13,389 residents in the Bloomsburg area, operating as part of the region's public sanitation infrastructure. As a plant serving a medium-sized agglomeration, it falls under the U.S. Clean Water Act framework, which requires secondary treatment as a baseline for municipal wastewater facilities. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection, ensuring compliance with effluent limits designed to protect water quality. The treated effluent from Bloomsburg STP discharges into a tributary of the Susquehanna River, which flows south through Pennsylvania and into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and an ecologically sensitive ecosystem that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient removal at plants like Bloomsburg STP is critical to reducing nitrogen and phosphorus loads that contribute to algal blooms and hypoxia in the bay.

The plant's discharge enters the Susquehanna River watershed, which drains into the Chesapeake Bay. The Chesapeake Bay is a vital estuary that supports a complex food web and is a key migratory corridor for fish and birds. Nutrient pollution from wastewater and agricultural runoff has historically caused eutrophication and dead zones, making advanced treatment and nutrient reduction important for the bay's health.
