New Holland Boro STP - Earl Township, Pennsylvania Wastewater Treatment Plant

New Holland Boro STP is a municipal wastewater treatment facility located in Earl Township, Lancaster County, Pennsylvania. The plant serves a population of approximately 6,292 residents in the New Holland area, operating as part of the region's water infrastructure. Its location in southeastern Pennsylvania places it within the Chesapeake Bay watershed, a major estuary system. As a US facility serving a population under 10,000, the plant is subject to EPA National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. These permits set effluent limits based on technology-based standards and water quality requirements. The plant's design capacity and treatment process details are not publicly available in this dataset, but typical facilities of this scale employ secondary treatment processes such as activated sludge or trickling filters. The plant's treated effluent ultimately drains into the Susquehanna River basin, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and is ecologically sensitive to nutrient pollution. The plant's discharge contributes to the bay's nutrient load, making compliance with nitrogen and phosphorus limits critical for downstream water quality and aquatic habitat.

The plant's discharge flows into local tributaries of the Susquehanna River, which empties into the Chesapeake Bay. The Chesapeake Bay is a vital estuary supporting diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater and agriculture has historically caused hypoxia and algal blooms in the bay, making effective treatment essential for ecosystem health.
