Fracking
is draining water from US areas suffering major shortages - report
Some
of the most drought-ravaged areas of the US are also heavily targeted
for oil and gas development using hydraulic fracturing - a practice
that exacerbates water shortages - according to a new report.

Three-quarters
of the nearly 40,000 oil and gas wells drilled in the US since 2011
were located in areas of the country facing water scarcity, according
to research by the Ceres investor network. Over half of those new
wells were in areas experiencing drought conditions.
Hydraulic
fracturing, or fracking,
in those wells required the use of 97 billion gallons of water, Ceres
found.
"Hydraulic
fracturing is increasing competitive pressures for water in some of
the country's most water-stressed and drought-ridden regions," said
Mindy Lubber, president of the Ceres green investors' network.
Lubber
warned that the fracking boom across the US puts the industry on a
“collision course” with other water users.
Fracking
is the highly controversial process of injecting water, sand, and
various chemicals into layers of rock, in hopes of releasing oil and
gas deep underground. Fracking in a single well can take millions of
gallons of freshwater. Much of the drilling has occurred in areas
mired in multi-year droughts.
Half
of the 97 billion gallons of water used since 2011 for fracking have
gone to wells in Texas, a state in the midst of a severe, years-long
drought. Meanwhile, oil and gas production through fracking is on
track to double in the state over the next five years, the Guardian
reported.
The
report also found that rural communities in the Lone Star State are
being hit hard by the fracking bonanza occurring especially in the
Eagle Ford Shale in south Texas.
"Shale
producers are having significant impacts at the county level,
especially in smaller rural counties with limited water
infrastructure capacity," the
report said. "With
water use requirements for shale producers in the Eagle Ford already
high and expected to double in the coming 10 years, these rural
counties can expect severe water stress challenges in the years
ahead."
Levels
of vital aquifers that serve local communities near Eagle Ford have
dropped by up to 300 feet in the last few years.
Many
small communities in areas of heavy fracking
in Texas are in dire need of water, as supplies have run out in some
places or will dry up soon in others. The Texas Commission on
Environmental Quality says 29 communities across the state could run
out of water in 90 days, and that many reservoirs in west Texas are
at around 25 percent capacity.
In
December, the San Antonio Express-News found that fracking was using
more water than previously thought. The newspaper reported that in
2012, the industry used around 43,770 acre-feet of water in 3,522
Eagle Ford fracking wells - about the same usage of 153,000 San
Antonio households.
“The
oil and gas boom is requiring more water than we have,” Hugh
Fitzsimons, a Dimmit County rancher and a director of the
Wintergarden Groundwater Conservation District, told the
Express-News. “Period.”
A
separate study published this week found that the industry does a
very poor job recycling fracking water in Texas. Researchers at the
University of Texas’ Bureau of Economic Geology found that 92
percent of water used in 2011 to frack Barnett Shale in north central
Texas was “consumed,” and
not recycled. Only about five percent of all water used for fracking
in that area has been reused or recycled in the “past
few years.”
Other
states do not fare well in the Ceres report, either. In Colorado, 97
percent of wells were in areas strapped for water, as demand for
fracking water in the state is expected to double to six billion
gallons – twice the annual use of the city of Boulder - by 2015.
In
California, 96 percent of new wells were located in areas where
competition for water is high. A drought emergency for the entire
state - which has traditionally dealt with water-sharing and access
problems - was declared last month.
The
report found similar high percentages of wells built in other states
– such as New Mexico, Utah and Wyoming – where water shortages
exist.
"It's
a wake-up call," said
Prof. James Famiglietti, a hydrologist at the University of
California, Irvine, according to the Guardian. "We
understand as a country that we need more energy but it is time to
have a conversation about what impacts there are, and do our best to
try to minimize any damage."
