CASPER, Wyo. (AP) — Wyoming officials are asking residents of Pavillion if they want cisterns and trucked-in water to replace wells that federal officials say may have been tainted by fracking.

The Associated Press reports a public meeting is planned May 31 to discuss the possibility.

The federal Environmental Protection Agency said in December that hydraulic fracturing may have had a role in polluting water wells in Pavillion.

Hydraulic fracturing, or fracking, uses pressurized water, sand and chemicals to crack open fissures within wells and improve the flow of oil and gas.

Encana Corp., the primary operator in the Pavillion gas field, objected to much of the EPA findings.

The state would pay for the cisterns. State officials are in talks with Encana about having the company subsidize the cost of hauling water.
