CHEYENNE, Wyo. — A U.S. Environmental Protection Agency official is defending a draft EPA report that theorizes gas industry activity including hydraulic fracturing may have polluted groundwater in Wyoming.

Republican Rep. Ralph Hall of Texas countered that the December report is but one example of the EPA “going after fracking everywhere it can.”
