WASHINGTON
-Scientists have found that methane and other gases pose a significant risk of contaminating drinking-water wells near natural gas drilling, raising new questions about possible health and safety risks from the production technique known as fracking.
A study published Monday in the Proceedings of the National Academy of Sciences found that drinking-water wells in northeastern Pennsylvania within a kilometer of high-volume hydraulic fracturing, or fracking, showed methane concentrations six times greater, on average, than in wells farther away.
