      *Something in the air?*

      Residents, and now officials, are questioning the gas industry's impact
      on air quality

      Susan Haire had taken just one step out of her pickup truck near her
      home above Battlement Mesa when an excruciating headache overcame her
      and she nearly passed out. She had been complaining of odd symptoms for
      months -- chronic sinus problems, strange nerve sensations up and down
      her legs -- but nothing like this.

      "It came on me like someone had hit both sides of my head with boards
      and I started to collapse," said Haire, who was irrigating near a gas
      well when the incident occurred last June.

      She has since complained of dizziness, disorientation and chemical
      sensitivity, and has taken to wearing breathing masks and respirators
      when she works outside to protect her from fumes she says she notices
      when others don't.

      Chris Mobaldi felt burning pains across her body for months, worsening
      until she could no longer dress herself. She became weak, chronically
      nauseous and developed a string of debilitating health problems
      culminating in a pair of pituitary gland tumors. In two years, friends
      said she aged 20 years. Most puzzling, a rare brain condition called
      foreign accent syndrome has left her speech sounding like she's from
      another country, or sometimes reduced to total gibberish. She said she
      had smelled fumes from the surrounding gas wells for months and
      complained of tainted well water.

      Karen Trulove began complaining of constant fatigue at her home south of
      Silt, and closed up her framing shop in town when she could no longer go
      to work. On the well pad above her home, a petroleum smell still fills
      the air, and on bad days she says the air around their home shares the
      same odor, accumulating in gullies and valleys on her land. Last week,
      she and her husband Tim put a "for sale" sign at the end of the road.
      Like Haire and Mobaldi, they are moving away from the industry they
      believe has made them sick.

      Pollutants raise concerns

      Throughout the gas fields of western Garfield County, dozens of
      residents have complained of health problems they believe are caused by
      the wells that have spread across the rolling sagebrush landscape.
      Complaints include dizziness, nausea, difficulty breathing, sinus
      problems, eye and skin irritation and blistering. More severe concerns
      have included cancer, neurological disorders and acute chemical

      "I've talked to people from Silt that are complaining about the exact
      same symptoms as outside of Parachute. Those folks have similar symptoms
      as people from outside of Rifle," said Matt Sura, energy organizer with
      the activist group Western Colorado Congress. "These are so consistent
      that there has to be some sort of causation there. And the one thing
      they have in common is ... that they live near oil and gas."

      Industry representatives say they've never seen proof of a connection.
      The Colorado Oil and Gas Conservation Commission, which regulates the
      industry, has investigated several such complaints and has never found
      any well responsible for health problems due to air quality.

      But some recent Garfield County air samples have shown unusually high
      levels of volatile organic compounds from the gas industry, raising
      concerns among some state health officials that the industry's expansion
      may be causing air pollution. That's caused speculation for the first
      time that gas drilling could be harming neighbors' health.

      "I think that's the question we want to answer ourselves," said Ray
      Mohr, with the Air Pollution Control Division of the Colorado Department
      of Public Health and Environment. "I think at this point, based upon
      what we've seen, we're led to conclude that might be the case, although
      we're not definitely saying that at this point."

      Industry questions link

      The county has begun monitoring air quality and it's embarked on a
      two-year study to examine residents' health complaints related to the
      industry. Mohr and other state health officials have examined the
      county's air samples.

      "There are hundreds of thousands of gas wells located clear across the
      United States, and across the world for that matter," said Brian Macke,
      director of the Colorado Oil and Gas Conservation Commission, which
      regulates energy production. "I'm not familiar with occurrences of
      health impacts from oil and gas operations because of air impacts.
      That's not to say that there aren't any, but I just haven't heard of
      those things, even from areas that have much higher (well) densities."

      Macke said his agency has received several complaints about air quality,
      but it's never found evidence to link health problems to gas emissions.
      They have investigated complaints brought by Haire, Mobaldi, Trulove and
      others, but found no ties to nearby wells.

      "While the Oil and Gas Commission is very concerned about any potential
      health impact from the gas industry, we do believe it's very important
      to consider other environmental factors or personal health history
      factors when looking into health problems," he said.

      Industry representatives say they've never seen a link between their
      emissions and human health.

      "Our experience has been that gas production activities in areas that
      are proximate to where people live have not been a problem and have not
      been shown to be a problem," said Greg Schnacke, senior vice president
      of the trade group the Colorado Oil and Gas Association.

      Air monitor results mixed

      While some residents have complained that clear Western skies sometimes
      become smoggy, most Garfield County air monitors have found few traces
      of pollution traced to the gas industry, and those chemicals have been
      well within safe levels.

      A few spot samples taken by residents participating in the program,
      though, have found highly-elevated levels of these volatile organic
      compounds, said Jim Rada, Garfield County's environmental health
      manager. Those samples, taken when residents have noticed strong odors
      in the air, have shown spikes in BTEX -- a mix of benzene, toluene,
      ethylbenzene and xylene. Although much higher than usual, those spikes
      were still well within occupation levels considered safe.

      Some neighbors worry they may be at risk from chronic exposure.

      "We had no idea that staying here with the finished wells would be so
      hard for us," said Karen Trulove, who found high BTEX readings when she
      took an air sample. She and her husband are leaving their home of 12
      years, a 40-acre spread with 11 horses that graze amid the sagebrush
      meadows where they had hoped to spend the rest of their lives.

      The county has set up monitoring stations throughout the county that
      take monthly 24-hour samples. Environmentalists worry that while those
      stations may gauge general air quality, they miss plumes from specific
      wells that have accidents or heavy emissions. The county has given eight
      grab sample monitors for residents in areas of heavy activity to use
      when they smell fumes. Those monitors, like the one Trulove used, came
      up with the highest BTEX levels.

      "I think that we're all at a point where we know there's a need to do
      more monitoring before we go out and say there's a specific problem or
      not," said Mohr, with the Air Pollution Control Division. It's too early
      to link the gas industry to Garfield County health problems, he said,
      but after seeing high readings, officials can't dismiss it.

      'Easy to point a finger'

      The county has contracted with the Saccomanno Research Institute, of St.
      Mary's Hospital in Grand Junction, to conduct a two-year study of
      residents' health complaints relating to the gas industry to see if
      there may be a link.

      "It's somewhat easy to point a finger, but we have to realize, too, that
      in any given community there's a certain number of these types of
      maladies that occur naturally," said Rada, the county health manager.
      "Sometimes it's related to environmental causes. Sometimes it's related
      to genetics or personal health issues or lifestyle issues. It's hard to
      put a finger on it, I'm sorry to say."

      Several residents, convinced that the gas industry is the source of
      their problems, have moved away, often leaving behind dream homes where
      they had hoped to retire, and some say their symptoms have improved ever
      since. Some have moved on after reaching cash settlements with energy
      companies, with provisions that they don't speak publicly about their

      "It was a feeling of being trapped," said Susan Haire, who has moved
      into a friend's home in East Texas and is trying to sell her home on
      Morrisania Mesa. "Being trapped inside the house while the environment
      was closing in on me. I did feel trapped and sacrificed and pretty angry."

      In an interview last fall, her nose was red and her eyes teary after
      working outside and she complained of forgetfulness and mental
      fogginess. During the winter, she said she was too chemically sensitive
      to use her home's gas heat. Since she moved in early April, she said,
      most of her symptoms have disappeared, although she says she still has
      moments -- reversing keys when she types or physical reactions to
      propane fumes.

      Mobaldi said her strength has improved since leaving Rulison for Grand
      Junction, but her foreign accent syndrome has continued.

      "These people know what they're doing," she said in halting speech with
      short vowels and rolled "r's" reminiscent of an Eastern European accent.
      "They've done these things before. They just drill their gas wells
      without any thoughts of the peoples or the children or anything like that."

      Recent improvements

      Industry representatives acknowledge fumes as an inherent part of gas
      production. They may come from the gas byproducts, or condensate, that
      sometimes sits in pits or vented tanks at well sites. Sometimes, those
      pits are burned off, releasing more compounds in the air. Well flaring
      can also release them, and the wells themselves may emit some odors.
      Emissions may worsen when there is a mechanical problem.

      The Truloves complain that a loose valve on a condensate tank on a well
      near their property has caused many of the emissions they've smelled,
      and frequent complaints to the company haven't ended them.

      "We aren't anti-industry," Tim Trulove said. "We just want them to
      manage themselves better.

      Companies have made improvements in recent years. Many have stopped well
      flaring and burning condensate pits altogether.

      "We take a lot of precautions to try to be sure we minimize emissions,"
      said Doug Hock, spokesman for EnCana Oil & Gas (USA), one of the biggest
      players in Garfield County's gas fields. "It's an ongoing thing. We
      always are looking at new technologies."

      At 34 well pads close to homes in Garfield County, the company uses
      combustors to burn off gases coming off tanks rather than release the
      fumes into the air. At an experimental facility north of Parachute, the
      company pumps away the condensate rather than storing it on site. The
      company also performs its own air monitoring for some emissions, but it
      doesn't monitor for volatile organic compounds, like BTEX, which is says
      is difficult to accurately monitor.

      "We are cognizant of the fact that (air quality) is a concern and it
      bothers landowners," Hock said, "but as far as long-term health impacts,
      I'm not aware of it."

      'It hit me so hard, so fast'

      Most complaints center on the pits and tanks of condensate, which can
      contain some of the chemicals injected underground to fracture the
      underlying rock and make it easier for the gas to escape.
      Environmentalists complain that those chemicals are kept secret, so
      neighbors can't know what they might be breathing.

      "I think they're truly experiencing some exposure and some exposure
      symptoms," said Theo Colborn, an environmental health analyst in Paonia
      who has been an industry critic. "Unfortunately, everybody's a little
      different. The mixes of these things are a little different. Basically
      what I'm fighting for is full disclosure."

      Concerns may also stem from more conventional sources. Dee Hoffmeister
      said the constant rumbling of diesel engines at a well site near her
      home south of Silt filled her home with fumes. She returned from a
      month-long family visit to find a gray cloud filling her front porch,
      she said, and the fumes caused her to pass out.

      Hoffmeister said she spent weeks recuperating at a daughter's home in
      Glenwood Springs while the energy company agreed to clean her home. She
      was weak, achy and had difficulty breathing, she said. She also
      complained of heightened chemical sensitivity. Even being near clothes
      at a department store caused a reaction, she said, and family members
      have complained of trouble breathing and reduced immunity.

      "It hit me so hard, so fast," she said. "I think it's because we were
      gone. Those fumes just filled up our house."

      Industry representatives say neighbors' fears are misplaced.

      "The oil and gas industry certainly isn't interested in having our
      processes impugned as being some sort of health hazard," said COGA's
      Schnacke. "We don't believe they are."

      Schnacke points to the COGCC's investigations into air quality
      complaints from neighbors that turned up nothing. "I'm not seeing
      evidence of health concerns in that population," he said.

      But Sura complains that the COGCC has no health specialists on staff.

      'Very hard to prove'

      "It's very hard to prove exactly what is to have caused an illness or an
      ailment," said Jennifer Goldman, of the Durango-based environmental
      group the Oil & Gas Accountability Project, "but it shouldn't be lost on
      anyone that these are environmental health issues."

      Cindee Nyland and her husband have rented the Mobaldis home for over a
      year. It's a sweeping spread where deer, bald eagles and wild turkeys
      have come to visit. A well pad sits down the lane, and dozens more are
      scattered nearby. Lights from drilling rigs across the valley at the
      foot of the Roan Plateau shimmer at night.

      "I haven't seen any problems," said Nyland, whose husband helps build
      roads for the gas industry. She said she hasn't seen the polluted well
      water or smelled the gas fumes the Mobaldis complained of.

      "I really think if the plants died or if I saw something really weird
      with the environment going on, it would bring questions to me," she
      said, "but I haven't seen any of that."

      For environmentalists like Goldman, though, the similar health
      complaints across the Rockies, from Alberta, Canada to the desert
      Southwest, where gas drilling has become prevalent, are too compelling
      to ignore.

      "We don't have solid studies to point to to say, 'here's what the
      chronic exposure is,' but we do know that people are experiencing
      impacts when they're living among those chemicals," she said.

      Among her neighbors south of Silt, Karen Trulove counts a half-dozen
      who have removed the batteries from their smoke alarms after they tired
      of hearing them mysteriously activated. She believes they were tripped
      by unseen chemicals in the air.

      She and Tim are moving to an empty lot on Spring Valley to escape the
      gas industry and start over again, much as Haire, the Mobaldis and
      others like them have done.

      "The whole thing is that these companies are above the law," she said.
      "When they move into the neighborhood, your rights move out."
