Fracking News: Contamination of Wells may be Remedied by Replacing Casing and Cementing

A new study finds contamination of drinking water in parts of Texas from the extraction of shale gas, but the primary cause is not what some people had feared.

Researcher Avner Vengosh says the contamination of the wells that they analyzed was not directly from the process of hydraulic fracturing deep underground, but from well-integrity problems such as poor casing and cementing.

“We can tell that the contamination derived from leaking of the shale gas wells, and therefore if those leaks could be fixed and corrected, this contamination could be avoided and stopped.”
