newly developed techniques involving horizontal drilling and high-volume hydraulic fracturing [which] have made it possible to extract previously inaccessible natural gas . . . The use of hydraulic fracturing to release natural gas from these shale formations has raised concerns with water-well owners and water-resource managers across the Marcellus and Utica Shale region (West Virginia, Pennsylvania, New York and parts of several other adjoining States). In order to manage water resources in areas of gas-well drilling and hydraulic fracturing in New York, the natural occurrence of methane in the State’s aquifers needs to be documented.The information contained in this report was compiled from information available from the
USGS's National Water Information System (NWIS). In particular the link for information on Groundwater should be helpful.
