Study finds more arsenic in north Texas water wells near drilling
North Texas water wells within two miles of active gas drilling sites contain higher concentrations of arsenic and other carcinogens, according to a study published in the journal Environmental Science and Technology. In the study, University of Texas at Arlington biochemists measured 100 wells across the Barnett Shale, believed to hold one of the largest natural gas reserves in the U.S., and compared the results to a similar study undertaken before hydraulic fracturing technology and higher natural gas prices opened the area to drilling.
