High methane in drinking water near fracking sites
Well construction and geology may both play a role

Drinking water from wells near hydraulic fracturing operations in Pennsylvania and New York contains more methane than samples taken farther away, a new study finds. The results point to faulty construction and local geology as contributing factors.
Local geology “absolutely matters,” says environmental scientist Robert Jackson of Duke University who led the work. Similar studies in Arkansas have not found evidence of methane infiltrating drinking water wells.
Chemical signatures suggest that s...
