This dataset contains the lithologic class and topographic position index information and quality-assurance and quality-control data not available in the online National Water Information System for 72 domestic wells sampled by the U.S. Geological Survey in Bradford County, Pennsylvania, May-August 2016. The topographic position index (TPI) for each well location was computed on the basis of a 25-meter digital elevation model (U.S. Geological Survey, 2009) using criteria reported by Llewellyn (2014) to indicate potential classes for topographic setting. The bedrock geologic unit and primary lithology were determined for each well location on the basis of the digital bedrock geologic map of Pennsylvania (Miles and...

Data in support of study evaluating effects of legacy-sediment removal on nutrients and sediment in Big Spring Run, Lancaster County, Pennsylvania, 2009-15 (ver. 2.0, November 2020)
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 from approximately 4.6 acres within the Big Spring Run study area in the fall of 2011. Monitoring has continued in the post-restoration period. This study was conducted in cooperation with the Pennsylvania Department of Environmental Protection, Franklin and Marshall College, and the US Environmental Protection Agency and examines...

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 sites downgradient from the facility during the baseline characterization period on days when surface-water samples were collected. This Data Release presents the quality control data from ALS laboratories for the groundwater, surface-water, and soil samples (ALS_QAQC.txt). Quality control replicate and blank water samples that are stored...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
