Pennsylvania Water Science Center

Data and Tools

USGS Pennsylvania Water Science Center operates about 580 real-time data collection sites in Pennsylvania for acquiring information on surface water, groundwater, water quality, and precipitation. These sites provide near real-time data via satellite communication and these data are provided to the public through the National Water Information System as well as through many USGS web applications.

Data in support of study evaluating effects of legacy-sediment removal on nutrients and sediment in Big Spring Run, Lancaster County, Pennsylvania, 2009-15

The stream corridor at the Big Spring Run restoration site has been identified as a substantial source of sediment and nutrients to streams due to streambank erosion and floodplain scour of legacy sediment. Three USGS streamgages were installed and water-quality monitoring began in water year 2009, prior to the legacy sediment removal from the restoration area. The legacy sediment was removed...

Quality Control and Soil Quality Data in support of Baseline Environmental Monitoring at the Ammonium Perchlorate Rocket Motor Destruction (ARMD) Facility at the Letterkenny Army Depot, Chambersburg, Pennsylvania, 2016

From September to December, 2016, herein referred to as the baseline characterization period, monthly samples were collected from four groundwater wells, one surface-water site, and nine soil samples near the ARMD Facility. The only surface-water site sampled monthly during the baseline characterization period was upgradient of the facility. There was no streamflow at surface-water site

Delaware River Basin Catchments Based on Strahler Stream Order 1 from National Hydrography Dataset (NHD) Stream Centerline Features for 8-digit HUC

In 2012, catchments were generated in the Delaware River Basin for 8-digit HUCs in the areas underlain by the Marcellus Shale (all of 02040101, 02040102, 02040103, 02040104; and headwater areas of 02040106 and 02040203) based on the National Hydrography Dataset (NHD) Strahler first- and second-order streams. There were areas that did not have a catchment generated so another met
