Fracking contaminated drinking water

Scientific American has an article that explains that a former EPA scientist has found contaminants in drinking water that came from fracking. Drinking water from Pavillion WY smells and tastes bad. There are many natural gas wells in the area, many shallow wells under 2000 feet deep. Chemicals used in fracking have been found in well water.

Many labs analyzing well water originally didn’t find fracking chemicals. But it’s not that simple.

“Conducting a groundwater investigation related to fracking is extremely complicated,” DiGiulio said. “It is difficult because a lot of the compounds used for hydraulic fracturing are not commonly analyzed for in commercial labs.”

More recent test have found methanol, diesel compounds, and other fracking chemicals in wells. Many of these chemicals are unstudied, and we don’t know what the safe levels are for them.

Unsurprisingly, industry groups disagree with the findings. More studies need to be done to find how fracking can be done such that it won’t contaminate well water.
