No Groundwater Contamination in Pennsylvania

A first round of tests showed no evidence that water at 11 homes in a small town in Pennsylvania near natural gas drilling operations had been polluted to unhealthy levels, U.S. environmental regulators said.

The Environmental Protection Agency said in January it would perform tests at about 60 homes in Dimock where residents have complained since 2008 of cloudy, foul-smelling water after Cabot Oil & Gas Corp began fracing for gas nearby.

Sampling results from the first round of 11 homes "did not show levels of contamination that could present a health concern," a regional EPA spokesman said in an email.

The EPA has been delivering fresh water to several homes in Dimock including three of the 11 homes. It will continue to provide water to those homes while it performs more sampling.

A Cabot spokesman said the company was pleased with the first round of results and it would continue to work with the EPA.

Fracing has without question, revolutionized the U.S. natural gas industry by giving companies access to vast new reserves that could supply the country's demand for 100 years. Though revolutionary, fracing isn't new; it's been in use for more than 6 decades.

Thanks to the technology behind Microseismic,  we are able to monitor microseismic events from or near the surface, in real-time.  Similar to a stethoscope on the chest of the reservoir, these technologies give insight as fracing happens, allowing operators to optimize field development plans and avoid fracturing into environmentally sensitive areas-whether that's the aquifer or a seismic fault.
