Fracking's
Terrifying Water Usage Trends Spell Disaster
New
study shows that fracking boom is happening in places that can least
afford to lose precious water supplies

The
irony of fracking: It destroys the natural resource it needs most.
The tragedy for those living nearby fracking operations: That natural
resource is the fresh—and increasingly scarce—water supply on
which they, too, depend.
And
not only does fracking—or hydraulic fracturing—demand enormous
amounts of fresh water no matter where it takes places, a troubling
new study released Wednesday found that a majority of places where
the controversial drilling technique is most prevalent are the same
regions where less and less water is available.
Overlay
the regions where most of the fracking is being done in North
American with the places experiencing the most troubling and
persistent water resource problems and the resulting picture becomes
an alarm bell as politicians and the fossil fuel industry continue to
push fracking expansion as the savior for the U.S. and Canada's
energy woes.
According
to the report, Hydraulic
Fracturing and Water Stress: Water Demand by the Numbers
(pdf), produced by the non-profit Ceres investor network, much of the
oil and gas fracking activity in both the U.S. and Canada is
happening in "arid, water stressed regions, creating significant
long-term water sourcing risks" that will strongly and
negatively impact the local ecosystem, communities, and people living
nearby.
“Hydraulic
fracturing is increasing competitive pressures for water in some of
the country’s most water-stressed and drought-ridden regions,”
said Ceres President Mindy Lubber, in announcing Hydraulic Fracturing
and Water Stress: Water Demand by the Numbers. “Barring stiffer
water-use regulations and improved on-the-ground practices, the
industry’s water needs in many regions are on a collision course
with other water users, especially agriculture and municipal water
use."
Richard
Heinberg, senior fellow of the California-based Post Carbon Institute
and author of a recent
book
on the "false promise" of the fracking industry, says the
irony of the study's findings "would be delicious if it weren't
so terrifying."
"Nationally,"
according to Heinberg, "only about 50 percent of fracking
wastewater is recycled. Billions of gallons of freshwater are still
taken from rivers, streams, and wells annually for this purpose,
and—after being irremediably polluted—this water usually ends up
being injected into deep disposal wells. That means it is no longer
available to the hydrological cycle that sustains all terrestrial
life."
The
study drew on industry data detailing water usage from from 39,294
oil and gas wells from January 2011 through May 2013 and compared
that information with "water stress indicator maps"
developed by the World Resources Institute (WRI).
What
it found:
Over
55 percent of the wells hydraulically fractured were in areas
experiencing drought and 36 percent overlay regions with significant
groundwater depletion – key among those, California which is in the
midst of a historic drought and Texas, which has the highest
concentration of shale energy development and hydraulic fracturing
activity in the U.S.
Specifically:
In
Texas, which includes the rapidly developing Eagle Ford and Permian
Basin shale plays, more than half (52 percent) of the wells were in
high or extreme high water stress areas. In Colorado and California,
97 and 96 percent of the wells, respectively, were in regions with
high or extremely high water stress. Nearly comparable trends were
also shown in New Mexico, Utah and Wyoming.
Among
hundreds of hydraulic fracturing companies whose water use was
evaluated, those with the highest exposure to water sourcing risk are
Anadarako (APC), Encana (ECA), Pioneer (PXD) and Apache (APA). Most
of the wells being developed by each of these companies are in
regions of high or extreme water stress. The top three service
providers, Halliburton, (HAL) Schlumberger (SLB) and Baker Hughes
(BHI), handled about half of the water used for hydraulic fracturing
nationally and also face water sourcing risks.
Although
water use for hydraulic fracturing is often less than two percent of
state water demands, the impacts can be large at the local level,
sometimes exceeding the water used by all of the residents in a
county.
"It's
a wake-up call," Professor James Famiglietti, a hydrologist at
the University of California, Irvine, told
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 minimise any damage."
The
irony of the latest findings, explained Heinberg in an email to
Common Dreams,
is based on the fact that "much of the fracking boom is centered
in the western United States—Texas, Oklahoma, Colorado, and
California—which just happens to be drying up, likely as a result
of climate change. And that climate change, in turn, is happening
because we're burning fossil fuels like oil and natural gas."
Heinberg
observed that the Ceres report is largely written from the standpoint
of the oil and gas companies—using much of their data—and
directed at those who may be invested or would like to invest in the
continuation or proliferation of the industry. However, he indicated,
detailing the increasing difficulties the industry and its investors
are likely to experience in sourcing water for their operations is
still valuable for those opposed to fracking.
"In
California, where I live," he said, "we're experiencing a
500-year drought. The grape-wine industry here in Sonoma County is
facing disaster. Farmers in the Central Valley are weighing whether
to plant at all this year. The fact that California's Democratic
governor [Jerry Brown] wants to spend what little water we have on
fracking—which will only make our climate problems worse—makes
the report frighteningly relevant."
