Detritus of Pennsylvania’s Shale Gas Boom

The supple hills of southwestern Pennsylvania, once known for their grassy woodlands, red barns, and one-stoplight villages, bristle with new landmarks these days: drilling rigs, dark green condensate tanks, fields of iron conduits lumped with hissing valves, and long, flat rectangles carved into hilltops like overgrown swimming pools, brimming with umber wastewater.
Tall metal methane flaring stacks periodically fill the night with fiery glares and jet engine roars. Roadbeds of crushed rock, guarded by No Trespassing signs, lie like fresh sutures across hayfields, deer trails, and backyards, admitting fleets of tanker trucks to the wellheads of America’s latest energy revolution.
This is the new face of Washington County, the leading edge of the nation’s breakneck shale gas boom. Natural gas boosters, President Barack Obama among them, have lauded it as a must-have, 100-year supply of clean, cheap energy that we cannot afford to pass up. However, recent data suggest that supplies of shale gas may last for only 11 years and that the extreme measures needed to recover it may make it a dirtier fuel than coal. But that hasn’t slowed the dramatic transformation of gas-rich regions from rural Pennsylvania to urban Fort Worth, Texas.
Driving this juggernaut is the amalgam of industrial technologies collectively known as "hydraulic fracturing," or "fracking," which releases the gases (the main component of which is methane) hidden deep within layers of ancient, splintery shale. With five major shale "plays" concentrated in eight states, and more under development, America has been transformed from a net importer of natural gas into a potential exporter.
Perched atop the 7,000-foot-deep Marcellus Shale formation, which undergirds most of Appalachia, Washington County not only boasts enormous reserves of methane but also leads the state in producing far more frack-worthy "wet gas" products: propane, butane, ethane, and other valuable chemicals that can mean the difference between a money pit and a money gusher. Although central Pennsylvania has more wells, this wet gas makes Washington County, in industry parlance, a "honeypot."
The lure of million-dollar payouts has led many farmers, homeowners, school boards, and town commissions to lease out their subterranean energy wealth. Royalty payments on leases so far have topped half a billion dollars statewide–money that, for some, is literally saving the farm.
"An unprecedented economic impact," Matt Pitzarella has called it. He’s spokesman for the leading driller in this part of the state, Texas-based Range Resources, which in 2004 fracked the first successful Marcellus Shale wells–at the time a shot in the dark and now believed to be tapping the second-largest natural gas field in the world. Pitzarella ticks off stories of poor families who hit the gas-lease lottery and are now able to afford college tuition, new cars, and home makeovers.
But unlocking half-billion-year-old hydrocarbon deposits carries a price, and not everyone shares in the bonanza. For every new shale well, 4 million to 8 million gallons of water, laced with potentially poisonous chemicals, are pumped into the ground under explosive pressure–a violent geological assault. And once unleashed, the gas requires a vast industrial architecture to be processed and moved from the wells to the world. Imagine the pipes, compressors, ponds, pits, refineries, and meters each shale well in Pennsylvania demands, planted next to horse farms, cornfields, houses, and schools. Then multiply by 5,000.
