Water Quality Monitoring to Inform Conservation Management, Fishing Creek, Clinton County, Pennsylvania
USGS conducted synoptic sampling of major-ion chemistry and the nitrogen and oxygen isotopic composition of nitrate in Fishing Creek during base flow to evaluate the occurrence and distribution of nutrients and to characterize biogeochemical processes.
USGS Upgrades StreamStats for Pennsylvania
The Pennsylvania Water Science Center (PaWSC) has upgraded StreamStats with the latest National Hydrography Dataset (NHD) flowlines and Watershed Boundary Dataset (WBD) drainage basins. More accurate basin delineations and basin characteristics, and improved estimates of streamflow are now available for any stream location in the Commonwealth of Pennsylvania.
USGS Develops a New Water-Quality Modeling Tool for Acid Mine Drainage Treatment Systems
USGS developed, in cooperation with the Office of Surface Mining Reclamation and Enforcement, “user-friendly” aqueous geochemical modeling tools to simulate changes in water quality during passive and active treatment of acid mine drainage as described in a new study.
Balancing Water Availability and Quality in the Delaware River Basin
New data visualization story shows how new USGS science and monitoring can inform water management
Region 1: North Atlantic-Appalachian PFAS Capability Team
Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic emerging contaminants. Some PFAS have been voluntarily phased out, as exposure has been linked to adverse human health effects.
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 and other rivers, and their tributaries, and eventually to the Chesapeake Bay. Additional research focuses on emerging contaminants and other stressors that effect human and aquatic life in the watershed and estuary.
Sediment Response of Stream Restoration Practices, Turtle Creek, Union County, Pennsylvania
USGS is providing data and analyses to assess stream restoration effectiveness in Turtle Creek, Union County, Pennsylvania, by measuring differences in sediment erosion and deposition in restored and eroded stream reaches.
"Legacy nitrogen" contributing to upward nitrate trends in streams
Despite the tremendous effort invested in reducing the use of nitrogen, widespread decreases in nitrate loads in US rivers and streams remain elusive—what gives? A new study from the USGS provides more evidence that the culprit is the slow release to streams of nitrogen that has accumulated in groundwater and other storage areas, known as legacy nitrogen.
Meeting the challenge: U.S. Geological Survey North Atlantic and Appalachian Region fiscal year 2020 in review
The utilization, preservation, and conservation of the Nation’s resources requires well-informed management decisions. The North Atlantic and Appalachian Region (NAAR) of the U.S. Geological Survey (USGS) supports science-based decision making for Federal, State, and local policymakers to meet the challenges of today and into the future. The science centers in the NAAR have well-deserved reputatio
USGS Unveils Mobile Flood Tool for the Nation
The U.S. Geological Survey announced Friday the completion of a new mobile tool that provides real-time information on water levels, weather and flood forecasts all in one place on a computer, smartphone or other mobile device.
