-------------------------------------

In a Brooklyn winery on a sultry July evening, an elegant crowd sips rosé and nibbles trout plucked from the gin-clear streams of upstate New York. The diners are here, with their checkbooks, to support a group called Chefs for the Marcellus, which works to protect the foodshed upon which hundreds of regional farm-to-fork restaurants depend. The foodshed is coincident with the Marcellus Shale, a geologic formation that arcs northeast from West Virginia through Pennsylvania and into New York State. As everyone invited here knows, the region is both agriculturally and energy rich, with vast quantities of natural gas sequestered deep below its fertile fields and forests. 

In Pennsylvania, the oil and gas industry is already on a tear—drilling thousands of feet into ancient seabeds, then repeatedly fracturing (or “fracking”) these wells with millions of gallons of highly pressurized, chemically laced water, which shatters the surrounding shale and releases fossil fuels. New York, meanwhile, is on its own natural-resource tear, with hundreds of newly opened breweries, wineries, organic dairies and pastured livestock operations—all of them capitalizing on the metropolitan area’s hunger to localize its diet.

But there’s growing evidence that these two impulses, toward energy and food independence, may be at odds with each other. 

Tonight’s guests have heard about residential drinking wells tainted by fracking fluids in Pennsylvania, Wyoming and Colorado. They’ve read about lingering rashes, nosebleeds and respiratory trauma in oil-patch communities, which are mostly rural, undeveloped, and lacking in political influence and economic prospects. The trout nibblers in the winery sympathize with the suffering of those communities. But their main concern tonight is a more insidious matter: the potential for drilling and fracking operations to contaminate our food. The early evidence from heavily fracked regions, especially from ranchers, is not reassuring. 

Jacki Schilke and her sixty cattle live in the top left corner of North Dakota, a windswept, golden-hued landscape in the heart of the Bakken Shale. Schilke’s neighbors love her black Angus beef, but she’s no longer sharing or eating it—not since fracking began on thirty-two oil and gas wells within three miles of her 160-acre ranch and five of her cows dropped dead. Schilke herself is in poor health. A handsome 53-year-old with a faded blond ponytail and direct blue eyes, she often feels lightheaded when she ventures outside. She limps and has chronic pain in her lungs, as well as rashes that have lingered for a year. Once, a visit to the barn ended with respiratory distress and a trip to the emergency room. Schilke also has back pain linked with overworked kidneys, and on some mornings she urinates a stream of blood.

Ambient air testing by a certified environmental consultant detected elevated levels of benzene, methane, chloroform, butane, propane, toluene and xylene—compounds associated with drilling and fracking, and also with cancers, birth defects and organ damage. Her well tested high for sulfates, chromium, chloride and strontium; her blood tested positive for acetone, plus the heavy metals arsenic (linked with skin lesions, cancers and cardiovascular disease) and germanium (linked with muscle weakness and skin rashes). Both she and her husband, who works in oilfield services, have recently lost crowns and fillings from their teeth; tooth loss is associated with radiation poisoning and high selenium levels, also found in the Schilkes’ water.

State health and agriculture officials acknowledged Schilke’s air and water tests but told her she had nothing to worry about. Her doctors, however, diagnosed her with neurotoxic damage and constricted airways. “I realized that this place is killing me and my cattle,” Schilke says. She began using inhalers and a nebulizer, switched to bottled water, and quit eating her own beef and the vegetables from her garden. (Schilke sells her cattle only to buyers who will finish raising them outside the shale area, where she presumes that any chemical contamination will clear after a few months.) “My health improved,” Schilke says, “but I thought, ‘Oh my God, what are we doing to this land?’”

Schilke’s story reminds us that farmers need clean water, clean air and clean soil to produce healthful food. But as the largest private landholders in shale areas across the nation, farmers are disproportionately being approached by energy companies eager to extract oil and gas from beneath their properties. Already, some are regretting it. 

Earlier this year, Michelle Bamberger, an Ithaca veterinarian, and Robert Oswald, a professor of molecular medicine at Cornell’s College of Veterinary Medicine, published the first (and, so far, only) peer-reviewed report to suggest a link between fracking and illness in food animals. The authors compiled case studies of twenty-four farmers in six shale-gas states whose livestock experienced neurological, reproductive and acute gastrointestinal problems. Exposed either accidentally or incidentally to fracking chemicals in the water or air, scores of animals have died. The death toll is insignificant when measured against the nation’s livestock population (some 97 million beef cattle go to market each year), but environmental advocates believe these animals constitute an early warning. 

Exposed animals “are making their way into the food system, and it’s very worrisome to us,” Bamberger says. “They live in areas that have tested positive for air, water and soil contamination. Some of these chemicals could appear in milk and meat products made from these animals.” 

In Louisiana, seventeen cows died after an hour’s exposure to spilled fracking fluid. (Most likely cause of death: respiratory failure.) In north central Pennsylvania, 140 cattle were exposed to fracking wastewater when an impoundment was breached. Approximately seventy cows died; the remainder produced eleven calves, of which only three survived. In western Pennsylvania, an overflowing waste pit sent fracking chemicals into a pond and a pasture where pregnant cows grazed: half their calves were born dead. The following year’s animal births were sexually skewed, with ten females and two males, instead of the usual 50-50 or 60-40 split. 

In addition to the cases documented by Bamberger, hair testing of sick cattle that grazed around well pads in New Mexico found petroleum residues in fifty-four of fifty-six animals. In North Dakota, wind-borne fly ash, which is used to solidify the waste from drilling holes and contains heavy metals, settled over a farm: one cow, which either inhaled or ingested the caustic dust, died, and a stock pond was contaminated with arsenic at double the accepted level for drinking water.

Cattle that die on the farm don’t make it into the nation’s food system. (Though they’re often rendered to make animal feed for chickens and pigs—yet another cause for concern.) But herd mates that appear healthy, despite being exposed to the same compounds, do: farmers aren’t required to prove their livestock are free of fracking contaminants before middlemen purchase them. Bamberger and Oswald consider these animals sentinels for human health. “They’re outdoors all day long, so they’re constantly exposed to air, soil and groundwater, with no break to go to work or the supermarket,” Bamberger says. “And they have more frequent reproductive cycles, so we can see toxic effects much sooner than with humans.”

Fracking a single well requires up to 7 million gallons of water, plus an additional 400,000 gallons of additives, including lubricants, biocides, scale and rust inhibitors, solvents, foaming and defoaming agents, emulsifiers and de-emulsifiers, stabilizers and breakers. About 70 percent of the liquid that goes down a borehole eventually comes up—now further tainted with such deep-earth compounds as sodium, chloride, bromide, arsenic, barium, uranium, radium and radon. (These substances occur naturally, but many of them can cause illness if ingested or inhaled over time.) This super-salty “produced” water, or brine, can be stored on-site for reuse. Depending on state regulations, it can also be held in plastic-lined pits until it evaporates, is injected back into the earth, or gets hauled to municipal wastewater treatment plants, which aren’t designed to neutralize or sequester fracking chemicals (in other words, they’re discharged with effluent into nearby streams). 

At almost every stage of developing and operating an oil or gas well, chemicals and compounds can be introduced into the environment. Radioactive material above background levels has been detected in air, soil and water at or near gas-drilling sites. Volatile organic compounds—including benzene, toluene, ethylene and xylene—waft from flares, engines, compressors, pipelines, flanges, open tanks, spills and ponds. (The good news: VOCs don’t accumulate in animals or plants. The bad news: inhalation exposure is linked to cancer and organ damage.) 

Underground, petrochemicals can migrate along fissures through abandoned or orphaned wells or leaky well casings (the oil and gas industry estimates that 60 percent of wells will leak over a thirty-year period). Brine can spill from holding ponds or pipelines. It can be spread, legally in some places, on roadways to control dust and melt ice. Truck drivers have also been known to illegally dump this liquid in creeks or fields, where animals can drink it or lick it from their fur.

Although energy companies don’t make a habit of telling potential lease signers about the environmental risks they might face, the Securities and Exchange Commission requires them to inform potential investors. In a 2008 filing, Cabot Industries cited “well site blowouts, cratering and explosions; equipment failures; uncontrolled flows of natural gas, oil or well fluids; fires; formations with abnormal pressures; pollution and other environmental risks.” In 2011, oil companies in North Dakota reported more than 1,000 accidental releases of oil, drilling wastewater or other fluids, with many more releases likely unreported. Between 2008 and 2011, drilling companies in Pennsylvania reported 2,392 violations of law that posed a direct threat to the environment and safety of communities. 

An inveterate label reader who obsessively tracks her animals’ nutritional intake, Schilke couldn’t figure out what was wrong. Neither could local veterinarians. She nursed individual cows for weeks and, with much sorrow, put a $5,000 bull out of its misery with a bullet. Upon examination, the animal’s liver was found to be full of tunnels and its lungs congested with pneumonia. Before the year was out, five cows had died, in addition to several cats and two dogs. (Hair testing of Schilke's  cats and dogs revealed elevated selenium levels, while water tests showed sulfate at levels high enough, Schilke's vet told her, to cause polio in cattle.) Inside Schilke’s house today, where the china cabinets are kept empty for fear of a shattering drill-site explosion, nearly a dozen cats sneeze and cough, some with their heads tilted at a creepy angle. 

Before the drilling started, two cars a day traveled down Schilke’s gravel road. Now, it’s 300 trucks hauling sand, fresh water, wastewater, chemicals, drill cuttings and drilling equipment. Most of the tankers are placarded for hazardous or radioactive material. Drilling and fracking a single well requires 2,000 truck trips, and each pass of a vehicle sends a cyclone of dust and exhaust fumes into the air. Mailbox numbers are obliterated, conversations are choked off, and animals die of “dust pneumonia.” (More formally known as bovine respiratory disease, the illness is associated with viral, fungal and bacterial infection.) 

Ordinarily, Schilke hauls her calves to auction when they’re eight months old. “Buyers come from everywhere for Dakota cows,” she says. The animals are then raised on pasture or in feedlots until they are big enough for slaughter. No longer Schilke cattle, they’re soon part of the commodity food system: anonymous steaks and chops on supermarket shelves. Now, Schilke is diffident about selling her animals. “I could get good money for these steers,” she says, cocking her head toward a pair of sleek adolescents. “They seem to be in very good shape and should have been butchered. But I won’t sell them because I don’t know if they’re OK.”

The relatively small number of animals reported sick or dead invites the question: If oil and gas operations are so risky, why aren’t there more cases? There likely are, but few scientists are looking for them. (“Who’s got the money to study this?” Colborn asks rhetorically.) Rural vets won’t speak up for fear of retaliation. And farmers aren’t talking for myriad reasons: some receive royalty checks from the energy companies (either by choice or because the previous landowner leased their farm’s mineral rights); some have signed nondisclosure agreements after receiving a financial settlement; and some are in active litigation. Some farmers fear retribution from community members with leases; 
others don’t want to fall afoul of “food disparagement” laws 
or get sued by an oil company for defamation (as happened with one Texan after video of his flame-spouting garden hose was posted on the Internet. The oil company won; the 
homeowner is appealing).

And many would simply rather not know what’s going on. “It takes a long time to build up a herd’s reputation,” says rancher Dennis Bauste, of Trenton Lake, North Dakota. “I’m gonna sell my calves, and I don’t want them to be labeled as tainted. Besides, I wouldn’t know what to test for. Until there’s a big wipeout, a major problem, we’re not gonna hear much about this.” Ceylon Feiring, an area vet, concurs. “We’re just waiting for a wreck to happen with someone’s cattle,” she says. “Otherwise, it’s just one-offs”—a sick cow here and a dead goat there, easy for regulators, vets and even farmers to shrug off. 

The National Cattlemen’s Beef Association takes no position on fracking, nor has it heard from members either concerned by or in favor of the process. And yet it’s ranchers and farmers—many of them industry-supporting conservatives—who are, increasingly, telling their stories to the media and risking all. These are the people who have watched helplessly as their livestock suffer and die. “It’s not our breeding or nutrition destroying these animals,” Schilke says, her voice rising in anger. “It’s the oilfield industry.” 

However, some institutions that specialize in risk have started to connect the dots. Nationwide Mutual Insurance, which sells agricultural insurance, recently announced that it would not cover damages related to fracking. Rabobank, the world’s largest agricultural bank, reportedly no longer sells mortgages to farmers with gas leases. And in the boldest move yet by a government official, Christopher Portier, director of the National Center for Environmental Health at the Centers for Disease Control and Prevention, called for studies that “include all the ways people can be exposed, such as through air, water, soil, plants and animals.” While the EPA is in the midst of a $1.9 million study of fracking’s impact on water, no government agency has taken up Portier’s challenge to study plants and animals. 

The possibility of chemical contamination aside, oil and gas operations have already affected food producers. “I lost six acres of hayfields when the gas company put roads in,” says Terry Greenwood, a rancher in western Pennsylvania. “Now I have to buy more feed for my cattle.” (Like other farmers hurt by drilling and fracking, he still pays taxes on his unproductive land.) Others have lost the use of stock ponds or creeks to brine spills. 

“We’ve got 12,000 wells in the Bakken, and they each take up six acres,” says Mark Trechock, former director of the Dakota Resource Council. “That’s 72,000 acres right there, without counting the waste facilities, access roads, stored equipment and man camps that go along with the wells.” Before the drilling boom, that land might have produced durum wheat, barley, oats, canola, flax, sunflowers, pinto beans, lentils and peas. In Pennsylvania, where nearly 6,500 wells have been drilled since 2000, the Nature Conservancy estimates that thirty acres are directly or indirectly affected for every well pad. 

East of the Rockies, intensive drilling and fracking have pushed levels of smog, or ground-level ozone, higher than those of Los Angeles. Ozone significantly diminishes crop yields and reduces the nutritional value of forage. Flaring of raw gas can acidify soil and send fine particulate matter into the air; long-term exposure to this material has been linked to human heart and lung diseases and disruption to the endocrine system. Earlier this year, the Environmental Protection Agency finalized standards that require reductions in airborne emissions from gas wells, although the industry has more than two years to comply.

Besides clean air, farmers need clean water—lots of it. But some farmers now find themselves competing with energy companies for this increasingly precious resource. At water auctions in Colorado, the oil and gas industry has paid utilities up to twenty times the price that farmers typically pay. In Wyoming, ranchers have switched from raising beef to selling their water. Unwilling to risk her animals’ health to creek water that’s possibly tainted, Schilke spent $4,000 last summer hauling safe water from town to her ranch. “I’d wait in line for hours,” she says, “usually behind tanker trucks buying water to frack wells.”  

Given the absence of studies on the impacts of drilling and fracking in plants and animals, as well as inadequate inspection and scant traceability in the food chain, it’s hard to know what level of risk consumers face when drinking milk or eating meat or vegetables produced in a frack zone. Unless, of course, you’re Jacki Schilke, and you feel marginally healthier when you quit eating the food that you produced downwind or downstream from drill rigs. But many consumers—those intensely interested in where and how their food is grown—aren’t waiting for hard data to tell them what is or isn’t safe. For them, the perception of pollution is just as bad as the real thing. Ken Jaffe, who raises grass-fed cattle in upstate New York, says, “My beef sells itself. My farm is pristine. But a restaurant doesn’t want to visit and see a drill pad on the horizon.” 

Nor do the 16,200 members of the Park Slope Food Co-op in Brooklyn, which buys one cow per week from Jaffe. “If hydrofracking is allowed in New York State, the co-op will have to stop buying from farms anywhere near the drilling because of fears of contamination,” says Joe Holtz, general manager of the co-op. That’s $4 million in direct sales, with economic multipliers up and down the local food chain, affecting seed houses, creameries, equipment manufacturers and so on. 

Already, wary farmers in the Marcellus are seeking land away from the shale. The outward migration is simultaneously raising prices for good farmland in the Hudson River Valley, which lies outside the shale zone, and depressing the price of land over the Marcellus. According to John Bingham, an organic farmer in upstate New York who is involved in regional planning, lower prices entice absentee investors to buy up farmland and gain favorable “farm rate” tax breaks, even as they speculate on the gas boom. “Fracking is not a healthy development for food security in regions near fracking or away from it,” Bingham concludes. 

Only recently has the Northeast’s local-foods movement reached a critical mass, to the point where colleges and caterers trip over themselves in the quest for locally sourced and sustainably grown products. (New York has the fourth-highest number of organic farms in the nation.) But the movement’s lofty ideals could turn out to be, in shale-gas areas, a double-edged sword. “People at the farmers’ market are starting to ask exactly where this food comes from,” says Stephen Cleghorn, a Pennsylvania goat farmer.

With a watchful eye on Pennsylvania’s turmoil, many New York farmers have started to test their water pre-emptively, in the event that Governor Andrew Cuomo lifts the state’s current moratorium on fracking. And in the commercial kitchens of a city obsessed with the provenance of its prosciutto, chefs like Heather Carlucci-Rodriguez, a founder of Chefs for the Marcellus and the executive pastry chef at Manhattan’s Print Restaurant, are keeping careful tabs on their regional suppliers.

“I have a map of the Marcellus and my farmers on 
my office wall,” Carlucci-Rodriguez says at the Brooklyn 
winery event. “So far, I haven’t stopped buying from any-
one. But I’m a believer in the precautionary principle.” She nods to a colleague who’s dishing up summer squash with peach slices and ricotta. “We shouldn’t have to be defending our land and water,” she says with a sigh. “We should 
be feeding people.”
