USGS: No Contamination from Fayetteville Shale Exploration Found in Sampled Wells

LITTLE ROCK, Ark. – A study that examined the water quality of 127 shallow domestic wells in the Fayetteville Shale natural gas production area of Arkansas found no groundwater contamination associated with gas production, according to a report released today by the U.S. Geological Survey.

 

Scientists analyzed water-quality data from samples taken in Van Buren and Faulkner counties in 2011, focusing on chloride concentrations from 127 wells and methane concentrations and carbon isotope ratios from a subsample of 51 wells. 

 

"For more than one hundred years, the USGS has been a source of freely available, unbiased information on our natural resources such as oil, gas, and water, helping government and local leaders make wise decisions for the public good," said USGS Director Marcia McNutt. "This new study is important in terms of finding no significant effects on groundwater quality from shale gas development within the area of sampling."

 

Chloride is a naturally occurring ion that is found at elevated levels in waters associated with gas production.  Chloride moves easily through groundwater without reacting with other ions or compounds in solution, making it is a good indicator of whether chemicals used during hydraulic fracturing are reaching groundwater.  In this case, the chloride concentrations from this study were not higher than samples taken from nearby areas from 1951 through 1983.
