Pennsylvania and the Chesapeake Bay Watershed

USGS provides monitoring, analysis, modeling and research on streams and water quality to better understand the fate and transport of nutrients and sediment to the Susquehanna River and its tributaries and eventually to the Chesapeake Bay. Additional research efforts in the Susquehanna River basin focus on emerging contaminants and other stressors that effect human and aquatic life in the...

Groundwater Quality of Domestic Supply Wells in Pennsylvania

Most rural residents in Pennsylvania use groundwater from domestic supply wells for drinking, cleaning and other purposes. Some groundwater samples have been analyzed for private purposes, but those results generally are not readily available to the public. Many of the publicly available water-quality samples from rural areas were collected more than 30 years ago. Quality-assured groundwater...

Delaware River Basin

In Pennsylvania, the USGS's water-resources roots date back to the late 1800's, with the initiation of streamflow gaging on the Delaware and Susquehanna Rivers and assessments of groundwater resources near Philadelphia. The USGS Pennsylvania Water Science Center continues to provide scientific information about the water resources of the Delaware River Basin, in cooperation with regional and...

Contaminant Fate and Transport Studies in Fractured Sedimentary Rock Aquifers at the former Naval Air Warfare Center (NAWC), West Trenton, N.J.

Contaminants associated with industrial, airport, and other activities are present in groundwater in fractured-rock aquifers, posing long-term hazards to drinking-water supplies and ecosystems. The heterogeneous character of fractured rock challenges our understanding, monitoring, and remediation of such sites.

Hydrologic and Water Quality Studies of PFAS in Pennsylvania

USGS is working with Federal, state, and local partners to monitor and evaluate perfluoroalkyl and polyfluoroalkyl substances (PFAS) in Pennsylvania's groundwater and surface waters.

The first-of-its-kind PFAS reconnaisence, in cooperation with the Pennsylvania Department of Environmental Protection, detected PFAS in Pennsylvania streams at 135 of 180 sampling locations; a subset of the...

Recoding of AMDTreat Phase 2: Integration of PHREEQ-N-AMDTreat water-quality prediction tools with recoded AMDTreat cost-analysis software

Newly developed PHREEQ-N-AMDTreat water-quality prediction tools indicate potential changes in pH, dissolved metals, and associated solute concentrations resulting from passive and active treatment of coal-mine drainage.

Mine Drainage and Water Quality Research

PaWSC conducts research on geochemical and hydrological processes that control water quality, particularly 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.

Harmful Algal Blooms in Pennsylvania

The U.S. Geological Survey is collaborating with State and local partners to develop models that provide real-time estimates of Escherichia coli (E. coli) (for pathogens) and (or) microcystin (for freshwater cyanotoxins) levels at Great Lakes beaches and drinking-water intakes.
