Well-water tests of 20 more homes in the embattled natural-gas drilling town of Dimock, Pa. showed no contamination levels "that present a health concern based on risk assessments," a spokesman for the U.S. Environmental Protection Agency said Friday.
"This set of sampling did not show levels of contaminants that would give EPA reason to take immediate action," said Roy Seneca, a spokesman in EPA's regional office in Philadelphia.
The test results reinforced initial findings the EPA released last month on its tests of 11 other residential water wells in the Susquehanna County township, the epicenter of a clash between opponents and supporters of natural gas development in the Marcellus Shale formation.
