Drought Watch/Warning Lifted for all Pennsylvania Counties
USGS groundwater and surface water monitoring data contributed to the Pennsylvania Department of Environmental Protection's (PaDEP) March 6, 2024, lifting of all drought watches and warnings for Pennsylvania counties.
USGS Works with Partners in 15 Cities to Improve Urban Waterways
Everyone deserves clean and healthy public waterways. USGS and Urban Waters Federal Partnership are investing ~$4 million to improve our Nation's water systems and help transform degraded urban riverscapes into cleaner, safer green spaces.

Hydrogeologic framework, water levels, and selected contaminant concentrations at Valmont TCE Superfund Site, Luzerne County, Pennsylvania, 2020
The Valmont TCE Superfund Site, Luzerne County, Pennsylvania is underlain by fractured and folded sandstones and shales of the Pottsville and Mauch Chunk Formations, which form a fractured-rock aquifer recharged locally by precipitation. Industrial activities at the former Chromatex Plant resulted in trichloroethene (TCE) contamination of groundwater at and near the facility, which was identified

New educational tool better illustrates the role humans play in water availability
Long-term impacts of impervious surface cover change and roadway deicing agent application on chloride concentrations in exurban and suburban watersheds
Roadway deicing agents, including rock salt and brine containing NaCl, have had a profound impact on the water quality and aquatic health of rivers and streams in urbanized areas with temperate climates. Yet, few studies evaluate impacts to watersheds characterized by relatively low impervious surface cover (ISC; < 15 %). Here, we use long-term (1997-2019), monthly streamwater quality data combine
Groundwater quality in selected Stream Valley aquifers, eastern United States
Groundwater provides nearly 50 percent of the Nation’s drinking water. To help protect this vital resource, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Project assesses groundwater quality in aquifers that are important sources of drinking water (Burow and Belitz, 2014). The stream-valley aquifers constitute one of the important aquifer systems being evaluated.
