Water Quality Trends

USGS Pennsylvania Water Science Center, in cooperation with the Pennsylvania Department of Environmental Protection, samples 28 wells biannually to monitor ambient groundwater quality conditions throughout Pennsylvania.

Issue: The Chesapeake Bay Program (CBP) partnership is striving to improve water-quality conditions in the Bay by using a variety of management strategies to reduce nutrient and sediment loads. The partnership uses monitoring results and modeling tools to implement management strategies, relying on the scientific community to synthesize existing information and direct new research to address...

Since 1969, the Pennsylvania Water Science Center has had a cooperative program with Chester County to measure and describe water resources. Cooperation has been primarily with the Chester County Water Resources Authority, with participation from the Chester County Health Department. This partnership provides Chester County with scientific information for water-resources management.

Since 2019, the USGS Pennsylvania Water Science Center has been cooperating with York County, Pennsylvania to implement in-stream monitoring to produce surrogate regression equations to compute, in real time, the concentration and load of total nitrogen, total phosphorus, and suspended sediment for 6 major watersheds in York County, Pennsylvania. This partnership provides the York County Planning...
