Pennsylvania Waters - Spring 2021 - Issue 4
This issue of our Pennsylvania Water Science Center Newsletter highlights USGS data on the occurrence of PFAS contaminants in surface waters across the Commonwealth, a first-of-its-kind survey, in cooperation with the Pennsylvania Department of Environmental Protection. USGS identified likely causes for changing low-flow statistics for streams in the Delaware River Basin, and there's more.
USGS and Pennsylvania Department of Agriculture study groundwater quality in agricultural areas
USGS Pennsylvania Water Science Center and the Pennsylvania Department of Agriculture have agreed on a new five-year program to continue 30 years of cooperation assessing groundwater quality in agricultural areas.
USGS Studies Low-Flow Changes in the Delaware River Basin
USGS scientists published a new study of low flow in streams in the Delaware River Basin. In general, the low flows measured during 1980-2018 increased along with increased precipitation, although low flows decreased in the Coastal Plain area, in the southern part of the basin, where water use and impervious surface have increased.
USGS at the Pennsylvania Groundwater Symposium
Penn State Extension and the Pennsylvania Department of Environmental Protection, along with numerous other sponsors, hosted the annual Pennsylvania Groundwater Symposium.
USGS scientists presented recent research and data delivery results at the 2022 Pennsylvania Groundwater Symposium (Virtual) on May 5, 2022.
First-of-its-Kind Survey of PFAS in Pennsylvania Surface Waters
In cooperation with the Pennsylvania Department of Environmental Protection
Water-level data and selected field notes for aquifer-interval-isolation tests at and near the former Naval Air Warfare Center Warminster, Bucks County, Pennsylvania, 2018-19 (ver. 2.0, January 2024)
The U.S. Geological Survey (USGS) conducted aquifer interval isolation (packer) tests of discrete water-bearing zones using straddle packers in 13 wells in Northampton, Warminster, and Warwick Townships and Ivyland Borough, Bucks County, Pennsylvania during 2018-19 to support detailed groundwater investigations at and near the former Naval Air Warfare Center (NAWC) Warminster, where groundwater co
Microplastics in the Delaware River, northeastern United States
Microplastics are a contaminant of increasing concern in aquatic environments. Our understanding of microplastics in freshwater environments has increased dramatically over the past decade, but we still lack information on microplastic occurrence and biological uptake in National Park Service (NPS) waters. During 2015–19, the U.S. Geological Survey and the NPS conducted a three-phase study of micr
Data-sharing agreement renewed to evaluate conservations practices and water quality in the Chesapeake Watershed
Issue: The U.S. Geological Survey (USGS) and the Natural Resources Conservation Service (NRCS) have a mutual interest in meeting the goals of the Chesapeake Bay Watershed Agreement, and in determining the benefits and challenges of agricultural conservation practices on water-quality patterns. Understanding the sources of nutrients and sediment and how these nutrients move into streams and groundwater is critical to design effective nutrient management and erosion control strategies.

Nutrient trends and drivers in the Chesapeake Bay Watershed
The Chesapeake Bay Program maintains an extensive nontidal monitoring network, measuring nitrogen and phosphorus (nutrients) at more than 100 locations on rivers and streams in the watershed. Data from these locations are used by United States Geological Survey to assess the ecosystem’s response to nutrient-reduction efforts. This fact sheet summarizes recent trends in nitrogen and phosphorus in n
