New test results due from Wyoming fracking zone

CHEYENNE, Wyo. (AP) — The U.S. Geological Survey plans to release results Wednesday from a new round of groundwater tests in a Wyoming gas field where another federal agency linked hydraulic fracturing to contaminants found in two water wells and local residents have complained of chemicals polluting their well water.

The new USGS data comes from samples taken in April from one of the test wells near Pavillion in central Wyoming. The other test well didn't produce enough water to yield samples deemed large enough to test.
