The Environmental Protection Agency has concluded that water in Dimrock, Pa., does not show hazardous levels of contaminants linked to fracking, the agency announced Friday. Homeowners in the town had filed complaints saying that their water appeared clouded and could be lit on fire. After testing 61 wells in the town, the EPA concluded that water in the town did not show contamination beyond the federal standards set for drinking. According to the agency, one home in the town did test for high levels of methane, but the EPA does not set standard for the presence of the gas. An earlier series of tests found elevated levels of contaminants at four well, and the agency said it will retest those.
