In the musical "Urinetown," a severe drought leaves the dwindling supplies of clean water in the hands of a corporation called Urine Good Company. Urine Good Company makes a fortune selling the precious commodity and running public toilets. It pays off politicians to ward off regulation and inspection. It uses the mechanisms of state control to repress an increasingly desperate and impoverished population.
The musical satire may turn out to be a prescient vision of the future. Corporations in Colorado, Texas, Louisiana, Pennsylvania and upstate New York have launched a massive program to extract natural gas through a process that could, if it goes wrong, degrade the Delaware River watershed and the fresh water supplies that feed upstate communities, the metropolitan cities of New York, Philadelphia, Camden and Trenton, and many others on its way to the Chesapeake Bay.
"The potential environmental consequences are extreme," says Fritz Mayer, editor of The River Reporter in Narrowsburg, N.Y. His paper has been following the drilling in the Upper Delaware River Valley and he told me, "It could ruin the drinking supply for 8 million people in New York City."
Trillions of cubic feet of natural gas are locked under the Marcellus Shale that runs from West Virginia, through Ohio, across most of Pennsylvania and into the Southern Tier of New York state. There are other, small plates of shale, in the south and west of the United States. It takes an estimated 3 million to 5 million gallons of water per well to drill down to the natural gas in a process called hydraulic fracturing, or fracking. The water is mixed with resin-coated sand and a cocktail of hazardous chemicals, including hydrochloric acid, nitrogen, biocides, surfactants, friction reducers and benzene to facilitate the fracturing of the shale to extract the gas.
The toxic brew is injected with extreme force deep within the earth. The drilling is vertical for about 5,000 to 7,000 feet. The technology, developed by Halliburton, allows drills to abruptly turn sideways when they reach these depths. The lubricant and biocides propel the sand on a horizontal axis for as far as half a mile. The fissures created are held open by the sand, and the natural gas flows to the surface through steel casings. Feeder lines run from the grid of wells to regional pipelines.
About 60 percent of the toxic water used to extract the natural gas—touted in mendacious commercials by the natural gas industry as "clean" energy—is left underground. The rest is stored in huge, open pits that dot the landscapes at drilling sites, before it is loaded into hundreds of large vehicles and trucked to regional filtration facilities. Such drilling has already poisoned wells in western Pennsylvania, Colorado, Alabama, Arkansas, New Mexico, Kansas, Montana, Virginia, Washington, West Virginia and Wyoming. Those whose water becomes contaminated, including people living in towns such as Dimock, Pa., must have water trucked in to provide for their needs. Farm animals that have drunk the toxic mixture that has leeched from gas drilling sites have died. Cattle ranchers in Colorado, where drilling is occurring in close proximity, have reported that their livestock birthrates have gone down and animals are bearing deformed offspring.
"The single biggest concern is the release of poisons into the environment and its impact on all that live in proximity to the drilling activity," the River Reporter's editorial this week read following a visit to local drilling sites. "Large pits, lined with sagging black plastic, did not instill confidence that it couldn't escape into the environment. And we wondered how migrating birds would know the difference between this body of fluid and an area pond. Ironically, the effect on animals became very real that afternoon when, upon our return, we received the news that in Caddo Parish, LA, 17 cows died after apparently ingesting fluids that escaped from a nearby gas pad."
