The company that has been using the controversial hydraulic horizontal natural gas drilling or “fracking” in Susquehanna County, Pennsylvania for years is suing two law firms and a resident of Dimock over claims the drilling has contaminated water in the area.

The Associated Press reports Cabot Oil and Gas is seeking $5 million in damages against Ray Kemble and his lawyers, claiming they tried to extort the company and had filed a frivolous lawsuit.

Dimock, Pennsylvania became the center of the fracking controversy when it was featured in the Emmy Award-winning documentary “Gasland” in 2010 and many residents still contend the drilling activities have contaminated their water.

A Federal lawsuit filed against Cabot Oil and Gas had been withdrawn two months after being filed.
