HARRISBURG, Pa. — A drilling tech­nique that is begin­ning to unlock stag­ger­ing quan­ti­ties of nat­ural gas under­neath Appalachia also yields a trou­bling byprod­uct: pow­er­fully briny waste­water that can kill fish and give tap water a foul taste and odor.

With for­tunes, water qual­ity and cheap energy hang­ing in the bal­ance, explo­ration com­pa­nies, sci­en­tists and entre­pre­neurs are scram­bling for an eco­nom­i­cal way to recy­cle the wastewater.

"Every­body and his brother is try­ing to come up with the 11 herbs and spices," said Nicholas DeMarco, exec­u­tive direc­tor of the West Vir­ginia Oil and Nat­ural Gas Association.

Drilling crews across the coun­try have been flock­ing since late 2008 to the Mar­cel­lus Shale, a rock bed the size of Greece that lies about 6,000 feet beneath New York, Penn­syl­va­nia, West Vir­ginia and Ohio. Geol­o­gists say it could become the most pro­duc­tive nat­ural gas field in the U.S., capa­ble of sup­ply­ing the entire country's needs for up to two decades by some estimates.

Before that can hap­pen, the indus­try is real­iz­ing that it must solve the chal­lenge of what to do with its waste­water. As a result, the Mar­cel­lus Shale in on its way to being the nation's first gas field where drilling water is widely reused.

The pol­luted water comes from a drilling tech­nique known as hydraulic frac­tur­ing, or "frack­ing," in which mil­lions of gal­lons of water, sand and chem­i­cals are blasted into each well to frac­ture tightly com­pacted shale and release trapped nat­ural gas. Read more.
