The US Environmental Protection Agency has been testing homeowners’ wells around Dimock, Pennsylvania, trying to determine if the water has been polluted the hydraulic fracturing (fracking) process used to extract natural gas. The agency is testing water at about 60 homes and Reuters reports that test results for the first 11 wells “did not show levels of contamination that could present a health concern.”
The agency did find a chemical cocktail in the water — sodium, methane, chromium, arsenic, or bacteria — in the water at 8 of the 11 homes, but the results were all within accepted safety ranges. The EPA could release more results of the testing around Dimock late next week.
The agency is re-testing wells near Pavillion, Wyoming, following initial testing that indicated that wells in the area had been contaminated by fracking fluids.
