In a first, federal environment officials today scientifically linked underground water pollution with hydraulic fracturing, concluding that contaminants found in central Wyoming were likely caused by the gas drilling process.

The findings by the Environmental Protection Agency come partway through a separate national study by the agency to determine whether fracking presents a risk to water resources.

In the 121-page draft report released today, EPA officials said that the contamination near the town of Pavillion, Wyo., had most likely seeped up from gas wells and contained at least 10 compounds known to be used in frack fluids.

“The presence of synthetic compounds such as glycol ethers … and the assortment of other organic components is explained as the result of direct mixing of hydraulic fracturing fluids with ground water in the Pavillion gas field,” the draft report states. “Alternative explanations were carefully considered.”

As the country awaits results from a nationwide safety study on the natural gas drilling process of fracking, a separate government investigation into contamination in a place where residents have long complained that drilling fouled their water has turned up alarming levels of underground pollution.

A pair of environmental monitoring wells drilled deep into an aquifer in Pavillion, Wyo., contain high levels of cancer-causing compounds and at least one chemical commonly used in hydraulic fracturing, according to new water test results released yesterday by the Environmental Protection Agency.

The findings are consistent with water samples the EPA has collected from at least 42 homes in the area since 2008, when ProPublica began reporting on foul water and health concerns in Pavillion and the agency started investigating reports of contamination there.

Last year — after warning residents not to drink or cook with the water and to ventilate their homes when they showered — the EPA drilled the monitoring wells to get a more precise picture of the extent of the contamination.

The Pavillion area has been drilled extensively for natural gas over the last two decades and is home to hundreds of gas wells. Residents have alleged for nearly a decade that the drilling — and hydraulic fracturing in particular — has caused their water to turn black and smell like gasoline. Some residents say they suffer neurological impairment, loss of smell, and nerve pain they associate with exposure to pollutants.

The gas industry — led by the Canadian company EnCana, which owns the wells in Pavillion — has denied that its activities are responsible for the contamination. EnCana has, however, supplied drinking water to residents.

The information released yesterday by the EPA was limited to raw sampling data: The agency did not interpret the findings or make any attempt to identify the source of the pollution. From the start of its investigation, the EPA has been careful to consider all possible causes of the contamination and to distance its inquiry from the controversy around hydraulic fracturing.

Still, the chemical compounds the EPA detected are consistent with those produced from drilling processes, including one — a solvent called 2-Butoxyethanol (2-BE) — widely used in the process of hydraulic fracturing. The agency said it had not found contaminants such as nitrates and fertilizers that would have signaled that agricultural activities were to blame.

The wells also contained benzene at 50 times the level that is considered safe for people, as well as phenols — another dangerous human carcinogen — acetone, toluene, naphthalene and traces of diesel fuel.

The EPA said the water samples were saturated with methane gas that matched the deep layers of natural gas being drilled for energy. The gas did not match the shallower methane that the gas industry says is naturally occurring in water, a signal that the contamination was related to drilling and was less likely to have come from drilling waste spilled above ground.

EnCana has recently agreed to sell its wells in the Pavillion area to Texas-based oil and gas company Legacy Reserves for a reported $45 million, but has pledged to continue to cooperate with the EPA’s investigation. EnCana bought many of the wells in 2004, after the first problems with groundwater contamination had been reported.

The EPA’s research in Wyoming is separate from the agency’s ongoing national study of hydraulic fracturing’s effect on water supplies, and is being funded through the Superfund cleanup program.

The EPA says it will release a lengthy draft of the Pavillion findings, including a detailed interpretation of them, later this month.

On a summer evening in June 2005, Susan Wallace-Babb went out into a neighbor’s field near her ranch in Western Colorado to close an irrigation ditch. She parked down the rutted double-track, stepped out of her truck into the low-slung sun, took a deep breath and collapsed, unconscious.

A natural gas well and a pair of fuel storage tanks sat less than a half-mile away. Later, after Wallace-Babb came to and sought answers, a sheriff’s deputy told her that a tank full of gas condensate—liquid hydrocarbons gathered from the production process—had overflowed into another tank. The fumes must have drifted toward the field where she was working, he suggested.The next morning Wallace-Babb was so sick she could barely move. She vomited uncontrollably and suffered explosive diarrhea. A searing pain shot up her thigh. Within days she developed burning rashes that covered her exposed skin, then lesions. As weeks passed, anytime she went outdoors, her symptoms worsened. Wallace-Babb’s doctor began to suspect she had been poisoned.

“I took to wearing a respirator and swim goggles outside to tend to my animals,” Wallace-Babb said. “I closed up my house and got an air conditioner that would just recycle the air and not let any fresh air in.”

Wallace-Babb’s symptoms mirror those reported by a handful of others living near her ranch in Parachute, Colo., and by dozens of residents of communities across the country that have seen the most extensive natural gas drilling. Hydraulic fracturing, along with other processes used to drill wells, generates emissions and millions of gallons of hazardous waste that are dumped into open-air pits. The pits have been shown to leak into groundwater and also give off chemical emissions as the fluids evaporate. Residents’ most common complaints are respiratory infections, headaches, neurological impairment, nausea and skin rashes. More rarely, they have reported more serious effects, from miscarriages and tumors to benzene poisoning and cancer.

ProPublica examined government environmental reports and private lawsuits and interviewed scores of residents, physicians and toxicologists in four states—Colorado, Texas, Wyoming and Pennsylvania—that are drilling hot spots. Our review showed that cases like Wallace-Babb’s go back a decade in parts of Colorado and Wyoming, where drilling has taken place for years. They are just beginning to emerge in Pennsylvania, where the Marcellus Shale drilling boom began in earnest in 2008.

The latest communication from the Sierra Club…

Did you know that communities in Wyoming sometimes have worse air quality days than Los Angeles due to natural gas drilling?1 Or that hydraulic fracturing – the drilling method used by the oil and gas industry – creates polluted wastewater which includes radioactive materials and toxic chemicals?

Unfortunately, oil and gas lobbyists have succeeded in carving out loopholes in the Safe Drinking Water Act and the Clean Air Act, leaving communities all over the country to suffer from the effects of unregulated drilling – dirty air and polluted drinking water.

Tell your representative that it is time to close these loopholes and protect our air and water from oil and gas drilling.

Companies involved in hydraulic fracturing should have to report the chemicals they pump underground, and their injection wells should be covered by the protections provided by the Safe Drinking Water Act. In addition, they should be required to meet Clean Air Act standards, just like other industries across the United States.

Tell Congress to end the environmental exemptions for the oil and gas industry.

People should not have to worry about the safety of their drinking water or breathe dirty air because of natural gas drilling. It’s time to close the loopholes in environmental laws that allow natural gas companies to evade government oversight and pollute our air and water.

Sincerely,

Deborah Nardone Sierra Club Natural Gas Reform Campaign

CHEYENNE, Wyo. – Wyoming, famous for its crisp mountain air and breathtaking, far-as-the-eye-can-see vistas, is looking a little bit like smoggy Los Angeles these days because of a boom in natural gas drilling.

Folks who live near the gas fields in the western part of this outdoorsy state are complaining of watery eyes, shortness of breath and bloody noses because of ozone levels that have exceeded what people in L.A. and other major cities wheeze through on their worst pollution days.

“It is scary to me personally. I never would have guessed in a million years you would have that kind of danger here,” Debbee Miller, a manager at a Pinedale snowmobile dealership, said Monday.

In many ways, it’s a haze of prosperity: Gas drilling is going strong again, and as a result, so is the Cowboy State’s economy. Wyoming enjoys one of the nation’s lowest unemployment rates, 6.4 percent. And while many other states are running up monumental deficits, lawmakers are projecting a budget surplus of more than $1 billion over the coming year in this state of a half-million people.

Still, in the Upper Green River Basin, where at least one daycare center called off outdoor recess and state officials have urged the elderly to avoid strenuous outdoor activity, some wonder if they’ve made a bargain with the devil. Two days last week, ozone levels in the gas-rich basin rose above the highest levels recorded in the biggest U.S. cities last year.

“They’re trading off health for profit. It’s outrageous. We’re not a Third World country,” said Elaine Crumpley, a retired science teacher who lives just outside Pinedale.

Preliminary data show ozone levels last Wednesday got as high as 124 parts per billion. That’s two-thirds higher than the Environmental Protection Agency’s maximum healthy limit of 75 parts per billion and above the worst day in Los Angeles all last year, 114 parts per billion, according to EPA records. Ozone levels in the basin reached 116 on March 1 and 104 on Saturday.

CHEYENNE, Wyo. — Four out of five people who have returned health surveys report respiratory problems in a central Wyoming community where some residents say gas drilling has polluted their water wells, an environmental group said Wednesday.

Respondents also reported headaches, nausea, itchy skin, dizziness and other ailments, according to the Earthworks Oil and Gas Accountability Project.

Wilma Subra, a Louisiana chemist and environmentalist who has investigated oil and gas industry pollution worldwide, is conducting the survey. She said survey forms from the first 16 people — more are coming in — show a need for public health officials to investigate.

“It’s critical to identify the health impacts and track them over time,” Subra said.

A spokesman for Encana Oil & Gas, the company that’s been developing gas in the Pavillion area, pointed out that the survey isn’t comprehensive.

“It is a survey, not really a study,” Doug Hock said. “Sixteen people, total.”

Earthworks suggested in a news release that the respiratory ailments result from exposure while people shower or wash dishes with contaminated water. Subra said in her report that the various ailments residents reported are associated with contaminants the U.S. Environmental Protection Agency has identified in Pavillion well water.
