At the heart of the international controversy over fracking has been the contention that the oil and gas drilling technique can contaminate people's drinking water, sometimes even causing it to light on fire. One poster child for this claim has been Steven Lipsky, a Texas homeowner who has appeared in a viral video with a garden hose spewing flames and says his water was fouled by fracking.
For years, Mr. Lipsky has fought legal battles — most often with federal EPA investigators finding his claims of contamination credible, while Texas regulators and the drilling company, Range Resources, taking the opposite view.
An analysis released this week, describing research by scientists at the University of Texas at Arlington, may open this case once again. It offers new evidence that the tests taken at Mr. Lipsky's well water by Range Resources and Texas regulators, who reported little or no contamination, were flawed and potentially inaccurate.
