Abstract
About 25,000 acres of area underlying the Deep and Dan River Basins in North Carolina has been identified to contain large shale gas reservoirs that could be used for the natural gas production. This study attempted to quantify the impact of potential hydraulic fracturing (or fracking) activities in the existing water resources of North Carolina. Supply and demand analysis was conducted using a water balance approach. Availability of surface water resources was quantified using the streamflow monitoring data of the surrounding area. A general assessment of the water demand for fracking was done using existing literature data and assumptions. Finally, a comparison was made between the water demand due to fracking and the water availability from nearby water sources. The preliminary analysis concluded that the surface water resources of North Caroline will not be affected at all as far as water quantity is concerned. However, whether extracting the shale gas of North Carolina is a good decision or not depends on the complete evaluation of the shale reservoirs and how well environmental impacts can be addressed.
Highlights
Shale gas is an extraordinary uprising source of energy since the advances in horizontal drilling and hydraulic fracturing allowed large scale production that made the shale gas extraction economically viable

It was assumed that only surface water will be used in the fracking operation
Summary
Shale gas is an extraordinary uprising source of energy since the advances in horizontal drilling and hydraulic fracturing allowed large scale production that made the shale gas extraction economically viable. In 2009, the North Carolina Geological Survey (NCGS) published a report on the existence of shale in North Carolina that extends across ~25,000 acres at depths less than 3,000 feet in the Sanford sub-basin, Lee and Chatham counties (Reid and Taylor, 2009). This entire area is underlying the Deep and Dan River Basins in twelve North Carolina counties. North Carolina law currently prohibits both horizontal drilling and the injection of waste into wells (Plikunas et al, 2012)
