SPATIAL AND TEMPORAL TRENDS IN GROUNDWATER QUALITY SURROUNDING SHALE GAS WELLS IN THE MARCELLUS SHALE
Rapid development of the Marcellus Shale, beginning in 2006, has outpaced scientific understanding of the potential impacts on groundwater in the region. Investigations into reports of groundwater contamination have been confounded by lack of baseline data, and by insufficient knowledge of legacy contamination, industry operations, and local hydrogeology. To help address this issue, we have collected time-series groundwater quality and hydrological data from multi-level groundwater monitoring wells installed in Susquehanna County, PA. We utilized prior knowledge of location and timing of industry operations to select locations for monitoring wells. We have collected samples from monitoring wells for approximately two years, on a monthly basis, prior to and throughout tophole and lateral drilling, stimulation of the Marcellus Shale with high volume hydraulic fracturing, and thereafter for seven horizontal shale gas wells installed on the four well pads. Findings from over 400 samples collected to date show that methane isotopic composition, as well as concentrations of trace metals, major ions, and hydrocarbons, exhibit significant variations in space and time. We will present our interpretation of these data in the context of local geology, hydrology, and the timing of shale gas extraction stages.
