New evidence that fracking may contaminate drinking water was published Monday in a study sure to add fuel to the fight over the controversial method of extracting natural gas from cracks in rocks.

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.

The ethane and propane contamination data are “new and hard to refute,” Jackson said.

“There is no biological source of ethane and propane in the region and Marcellus gas is high in both, and higher in concentration than the Upper Devonian gas found in-between,” he said in a statement.
