The Environmental Protection Agency (EPA) is currently conducting a national study to determine if hydraulic fracturing has any impact on drinking water sources. As part of a larger study, the EPA is conducting five focused retrospective studies in separate areas across the country including Bradford County, Pennsylvania.

Samples were taken in Bradford County during the study�s first round of sampling in October and November 2011. In a collaborative effort, Chesapeake Energy Corporation consultants collected split samples with the EPA from 15 individual drinking water sources for analysis by accredited laboratories. Chesapeake then commissioned WESTON Solutions, Inc. to critically evaluate the results and compare them with more than 4,000 historic and baseline groundwater samples in the area. Approximately 310 of these samples came from the United States Geologic Survey�s public databases and predate any Marcellus Shale natural gas development activity in the area. Based on the data evaluated, WESTON has concluded these drinking water sources have not been impacted by Marcellus Shale natural gas development activity � including hydraulic fracturing.

In advance of a public release, these findings were submitted to the EPA, Pennsylvania Department of Environmental Protection and landowners involved in this study. Chesapeake hopes the EPA will find WESTON�s report useful in meeting Congress� request for independent sources of information to be included in the agency�s influential scientific assessment regarding hydraulic fracturing.
