CHEYENNE, Wyo. (AP) — The state of Wyoming, U.S. Environmental Protection Agency and two American Indian tribes announced Thursday they have agreed to additional testing of groundwater that the federal agency says may have become contaminated by gas development that includes hydraulic fracturing.
They also agreed to postpone a scientific peer review of a draft EPA report on the contamination in the Pavillion area in central Wyoming until after the additional sampling and analysis. The peer review had been scheduled to begin within the next several weeks and now won't get under way this fall, according to the EPA.
Hydraulic fracturing, or fracking, uses pressurized water, sand and chemicals to crack open fissures within wells and improve the flow of oil and gas. A report released in December was the first time the EPA said fracking may have polluted groundwater in a specific case.
