(OilPrice) Samples from drinking water wells show no evidence of groundwater contamination from shale gas production in Arkansas.
"Our results show no discernible impairment of groundwater quality in areas associated with natural gas drilling and hydraulic fracturing in this region," says Avner Vengosh, professor of geochemistry and water quality at Duke University's Nicholas School of the Environment.
Scientists sampled 127 shallow drinking water wells in areas overlying Fayetteville Shale gas production in north-central Arkansas. They analyzed the samples for major and trace elements and hydrocarbons, and used isotopic tracers to identify the sources of possible contaminants.
