Stephen Osbоrn аnd three cоlleаgues frоm Duke University set out to leаrn whether drinking water was really being contaminated by nearby hydrofracking. The researchers visited private wells that draw drinking water from aquifers that lie above the Marcellus and Utica Shale formations in Pennsylvania and New York. With the homeowners' permission, they collected samples from 68 wells and tested their chemical composition. Half of the water wells were located within 1000 meters of active gas drilling sites; the other half were more than 1000 meters away from the nearest drilling site. Osborn and his colleagues tested the concentration of methane, the primary gaseous component of natural gas, & they found the following: According to the graph above, the quantity of water wells that had methane concentrations above the "action level" zone stipulated by the U.S. Department of Interior that were 1000 meters or less from the nearest drilling site was _______.
