EPA’s faulty claims of fracking-caused groundwater contamination are recounted in the WSJ.
“Meanwhile, the USGS found significantly lower concentrations of other materials identified by the EPA—including phenol, potassium and diesel-range organics—which might not have resulted from the fracking at all. The phenols were likely introduced accidentally in the laboratory, for example, and potassium might be naturally occurring or the result of potash contained in the cement used to build the EPA wells. The USGS also noted that in constructing the monitoring wells, the EPA used a “black painted/coated carbon steel casing,” and EPA photographs show that investigators used a painted device to catch sand from the wells. The problem is that paint can contain a variety of compounds that distort test results—so it is poor scientific practice to use painted or coated materials in well-monitoring tests.” [Wall Street Journal subscription required]
