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 methodology needed to be used in an attempt to fill in the 'gap areas'. A 900-cell, flow accumulation raster generated for the Pennsylvania StreamStats application was used as a surrogate stream layer with the same Strahler ordering system applied to help fill in the 'gap areas'. Points were manually placed at the downstream end of the Strahler...

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...

The Appalachian Landscape Conservation Cooperative (LCC) provided a grant to Cornell University Environmental Engineers to study how the region’s surface freshwater supply and the health of natural systems delivering this resource have been impacted and may be altered in the coming years under increasing water withdrawals.The research focuses on the Marcellus Shale region in the Central Appalachians, including portions of New York, Pennsylvania, Ohio, Maryland, West Virginia, and Virginia. In addition to considering the cumulative impacts of water withdrawals, the researchers looked at specific impacts of large water withdrawals with hydraulic fracturing in the Marcellus Shale region as one example.Datasets include...
