The Environmental Protection Agency (EPA) said on Tuesday that natural gas drilling by the company has contributed to the contamination of at least two residential drinking water wells in the county and ordered it to step in immediately.

The company said its investigations revealed that methane in the aquifer existed long before its drilling and likely is a naturally occurring migration from several shallow gas zones immediately below the water aquifer.
