SAN FRANCISCO (AP) — The latest domestic energy boom is
sweeping through some of the nation's driest pockets, drawing millions
of gallons of water to unlock oil and gas reserves from beneath the Earth's surface.
Hydraulic fracturing, or the drilling technique commonly known as
fracking, has been used for decades to blast huge volumes of water, fine
sand and chemicals into the ground to crack open valuable shale
formations.
But now, as energy companies
vie to exploit vast reserves west of the Mississippi, fracking's new
frontier is expanding to the same lands where crops have shriveled and
waterways have dried up due to severe drought.
In Arkansas, Colorado,
New Mexico, Oklahoma, Texas, Utah and Wyoming, the vast majority of the
counties where fracking is occurring are also suffering from drought,
according to an Associated Press analysis of industry-compiled fracking
data and the U.S. Department of Agriculture's official drought
designations.
While fracking typically consumes less water than farming or
residential uses, the exploration method is increasing competition for
the precious resource, driving up the price of water and burdening
already depleted aquifers and rivers in certain drought-stricken
stretches.
Some farmers and city leaders worry that the fracking boom is
consuming too much of a scarce resource, while others see the push for
production as an opportunity to make money by selling water while
furthering the nation's goal of energy independence.
Along Colorado's Front Range, fourth-generation farmer Kent Peppler
said he is fallowing some of his corn fields this year because he can't
afford to irrigate the land for the full growing season, in part
because deep-pocketed energy companies have driven up the price of
water.
"There is a new player for water, which is oil and gas," said
Peppler, of Mead, Colo., who also serves as president of the Rocky
Mountain Farmers Union. "And certainly they are in a position to pay a
whole lot more than we are."
In a normal year, Peppler said he would pay anywhere from $9 to $100
for an acre-foot of water in auctions held by cities with excess
supplies. But these days, energy companies are paying some cities $1,200
to $2,900 per acre-foot. The Denver suburb of Aurora made a $9.5
million, five-year deal last summer to provide the oil company Anadarko
2.4 billion gallons of excess treated sewer water.
In South Texas, where drought has forced cotton farmers to scale
back, local water officials said drillers are contributing to a drop in
the water table in several areas.
For example, as much as 15,000 acre-feet of water are drawn each year
from the Carrizo-Wilcox Aquifer to frack wells in the southern half of
the Eagle Ford Shale, one of the nation's most profitable oil and gas fields.
That's equal to about half of the water recharged annually into the
southern portion of the aquifer, which spans five counties that are home
to about 330,000 people, said Ron Green, a scientist with the nonprofit
Southwest Research Institute in San Antonio.
The Eagle Ford, extending from the Mexican border into East Texas, began to boom in 2011, just as Texas
struggled with the worst one-year drought in its history. While
conditions have improved, most of the state is still dealing with some
level of drought, and many reservoirs and aquifers have not been fully
replenished.
"The oil industry is doing the big fracks and pumping a substantial
amount of water around here," said Ed Walker, general manager of the
Wintergarden Groundwater Conservation District, which manages an aquifer
that serves as the main water source for farmers and about 29,000
people in three counties.
"When you have a big problem like the drought and you add other
smaller problems to it like all the fracking, then it only makes things
worse," Walker said.
West Texas cotton farmer Charlie Smith
is trying to make the best of the situation. He plans to sell some of
the groundwater coursing beneath his fields to drillers, because it
isn't enough to irrigate his lands in Glasscock County. Smith's fields,
like the rest of the county, were declared to be in a drought disaster
area this year by the USDA.
"I was going to bed every night and praying to the good Lord that we
would get just one rain on the crop," said Smith, who hopes to earn
several thousand dollars for each acre-foot of water he can sell. "I
realized we're not making any money farming, so why not sell the water
to the oil companies? Every little bit helps."
The amount of water needed to hydraulically fracture a well varies
greatly, depending on how hard it is to extract oil and gas from each
geological formation. In Texas, the average well requires up to 6
million gallons of water, while in California each well requires 80,000
to 300,000 gallons, according to estimates by government and trade
associations.
Depending on state and local water laws, frackers may draw their
water for free from underground aquifers or rivers, or may buy and lease
supplies belonging to water districts, cities and farmers. Some of the
industry's largest players are also investing in high-tech water
recycling systems to frack with gray or brackish water.
Halliburton, for instance, recently started marketing a new
technology that allows customers to use recycled wastewater, calling it
an "investment to further the sustainable development of the oil and gas
industry." The American Petroleum Institute, the principal lobbying
group for the industry, said its members are working to become less
dependent on fresh water, and instead draw on other sources.
"Recycling wastewater helps conserve water use and provide
cost-saving opportunities," said Reid Porter, a spokesman for the group.
In some states, regulators have stepped in to limit the volume or
type of water that energy companies can use during drought conditions.
In northwest Louisiana, as the production rush began in the
Haynesville Shale in 2009, the state water agency ordered oil and gas
companies to stop pulling groundwater from the local aquifer that also
supplied homes and businesses, and use surface water
instead. That order is still in effect and has helped groundwater
levels to recover, said Patrick Courreges, a spokesman for the Louisiana
Department of Natural Resources.
In Colorado's Weld County, home to Peppler's farm and more than
19,000 active oil and gas wells, some officials see selling unneeded
portions of their allotments from the Colorado River as a way to shore
up city budgets.
The county seat of Greeley sold 1,575 acre-feet of water last year to
contractors that supply fracking companies, and made about $4.1
million. It sold farmers nearly 100 times more water but netted just
$396,000.
"The oil and gas industry is a small but significant player," said
Jon Monson, director of the city's water department, which has
designated 35 fire hydrants where haulers may fill up their tanks to
truck to gas wells. "Just knowing that oil and gas is a boom-and-bust
industry, we are trying to not get used to it as a source of revenue
because we know it won't last."
Some environmental groups argue that local and regional planners
should let the public weigh in on how much drilling can be supported in
drought-stricken areas. Some states require oil and gas companies to
disclose the chemicals and the amount of water they use in fracking
operations on FracFocus.org, a website formed by industry and
intergovernmental groups in 2011, but the statistics are not complete.
"We don't want to look up 20 years from now and say, 'Oops, we used
up all our water,'" said Jason Bane of the Boulder, Colo.-based Western
Resource Advocates.
In California, oil companies are pressing for further exploration of
the massive Monterey Shale, a 1,750-square-mile area extending from the
agricultural Central Valley to the Pacific Ocean that federal energy
officials say could ultimately comprise two-thirds of the nation's shale
oil reserves.
In Ventura County, at the southern tip of the Monterey Shale and an
hour north of Los Angeles, drought-induced pressures on local water
systems are already visible; one local water district predicts some
groundwater wells will go dry by summer.
David Schwabauer, a fourth-generation farmer in the county, said
overtures by companies that want to drill new wells amid his avocado and
lemon groves are prompting difficult conversations about how to manage
the family farm. One orchard relies on irrigation from an overdrawn
aquifer, while the other is kept alive using expensive water piped in
from the distant Sierra Nevada mountains.
"Some parts of the family have very strong feelings against it, given
the challenges that we face environmentally," Schwabauer said. "But
other parts of the family are very comfortable with it, because we still
have to stay in business. We still haven't reached a decision."
