A new study by Duke University researchers and the U.S. Geological Survey (USGS) finds “no evidence of groundwater contamination from shale gas production in Arkansas.” The study, published in the peer-reviewed journal Applied Geochemistry (full copy embedded below), looked at samples from 127 water wells across the state. In those few cases where they found methane, it wasn’t methane from deep below (i.e. drilling) but rather naturally occurring methane from near the surface. No fracking chemicals were found in well water.
This study is yet another nail in the coffin of shrill, anti-drilling blathering that shale drilling “contaminates water supplies.” The science clearly says it does not.
