Time of travel of releases from Lake Wallenpaupack to the U.S. Geological Survey’s streamgage monitoring location on the Delaware River at Montague, New Jersey
In 2016, the U.S. Geological Survey (USGS) carried out a hydraulic study within the upper Delaware River Basin for the purpose of determining the time of travel for water releases from the Brookfield Renewable U.S. hydroelectric plant at Lake Wallenpaupack, Pennsylvania, to reach the USGS streamgage located on the Delaware River at Montague, New Jersey (site number 01438500). From...
Hydrologic investigations and a preliminary conceptual model of the groundwater system at North Penn Area 1 Superfund Site, Souderton, Montgomery County, Pennsylvania
The U.S. Geological Survey (USGS) conducted hydrogeologic investigations, reviewed existing data, and developed a preliminary conceptual model of the groundwater system as part of technical support of the U.S. Environmental Protection Agency (EPA) at the North Penn Area 1 Superfund Site (hereafter, the NP1 Site) located within the Borough of Souderton in Montgomery County, Pennsylvania...

Informing Chesapeake Bay Watershed Management by Monitoring Trends in River Nutrient and Sediment Loads
The USGS has computed nutrient and suspended-sediment loads and trends through water year 2023 in Chesapeake Bay rivers. These monitoring-based estimates help federal, state, and local managers evaluate and plan water-quality restoration strategies.
York County Sediment and Nutrient Monitoring
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...
Mine Drainage and Water Quality Research
The USGS Pennsylvania Water Science Center conducts research on geochemical and hydrological processes that control water quality, including the sources, transport, and attenuation of metals and nutrients in undisturbed and mining-impacted watersheds and aquifers. Results apply to scientific and regulatory programs for the prevention and remediation of aquatic contamination.
