PAVILLION, Wyo. (AP) — A state program that provides cisterns to homeowners with polluted groundwater in the Pavillion area could run out of money before everybody who wants a cistern gets one.

The Wyoming Legislature allocated $750,000 to the program in 2012. The funding so far has helped to pay for about 20 cisterns and a water-loading station.

Now, eight more households express interest in getting cisterns but only about $100,000 of the original funding remains. The program manager for the Wyoming Water Development Commission says money could get tight and might need to be supplemented.

The Associated Press reports that enrollment in the cistern program remains open.

State officials continue to investigate how decades of oil and gas development in the area might have played a role in the pollution.
