Fracking: leaking wells cause gas-contaminated groundwater

by European Commission, Environment DG  (Feb. 26, 2015)

Contamination of drinking water in areas close to several fracking sites in the Marcellus and Barnett Shales, USA, is caused by structural problems leading to wells leaking natural gas into aquifers, a new study suggests. The researchers measured trace amounts of chemicals, called noble gases, which formed signatures of the sources of gas ...
