Fracking taints water - study
Published on by Water Network Research, Official research team of The Water Network in Technology
Researchers at Duke University analyzed 141 drinking water samples from private water wells across the gas-rich Marcellus shale basin in northeastern Pennsylvania. They found methane concentrations were six times higher and ethane concentrations were 23 times higher at homes within a kilometer of a shale gas well.
Propane was detected in 10 samples, all of them from homes within a kilometer of drilling.
"The methane, ethane and propane data, and new evidence from hydrocarbon and helium isotopes, all suggest that drilling has affected some homeowners' water," said study author Robert Jackson, an environmental sciences professor.
