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.
