Peter Smith- Opposing arguments asserting that fracking contaminates ground water are simply unfounded. The most prominent study that is cited in how Fracturing pollutes groundwater was done by Duke University. It claims that researchers found high levels of methane in several water wells, near fracturing facilities. The only problem with the study was that it also reported to have found no fracturing fluid in the wells it tested, and the researchers did not test the methane levels before the fracturing occurred. Perhaps the wells had high methane content, but if it was truly from fracking it would also contain fracturing fluid. Clearly the study just identified wells that already had high levels of natural methane before the fracturing occurred. Researchers did a survey of all studies on fracturing, and found that not a single one associated fracturing fluid with ground water near fracturing wells. All the studies found was methane, which could have been there naturally.
