Marcellus shale is generating a lot of natural gas activity in Appalachia these days. The formation lies primarily in New York, Pennsylvania, Ohio and West Virginia, and is located a mile or more below the surface in some places. Marcellus shale is thought to be a new horizon in the natural gas industry, but I am very concerned regarding the technique used to extract the gas as well as the environmental concerns that go along with it. The Marcellus compilation requires a lot more water than a conventional well in West Virginia, which has raised questions for concerned citizens and lawmakers alike regarding where the water comes from, how polluted it is after usage and what happens to it after it is used? In the past, producers extracted gas from permeable formations that gas moves through freely which “completes” drilled wells by installing equipment, cementing to protect groundwater and making the gas flow for the producer.
