Science Challenges• Appalachian Hydro-Geology iscomplex and poorly understood• Natural system masked by historicand current development• Reference conditions poorly defined• Studies in a few watersheds will notprovide the scope of informationneeded for the region.Unconventional Oil and Gasdevelopment requiresunconventional scientificassessment methods
Assessment Strategy1) Describe baseline conditions: Hydrogeologic, geochemical, landscape,and biological and ecological characteristics2) Determine the geochemical signatures: Geochemical characteristicsand volume of waste products including drill cuttings and flowback3) Determine Current Development Effects: Distribution and flowpaths offreshwater, saltwater, and gas above the Marcellus; induced seismicity;landscape changes4) Understand potential contaminant sources and pathways: includingsurface spills, waste disposal, poorly sealed wells, abandoned wells,natural fractures, and induced fractures5) Understand, map, and track the risks: air and water quality, inducedseismicity, associated health risks, habitat, monitoringLeverage, share, and collaborate
