The Ogallala and The Keystone
The Ogallala Aquifer is an American treasure. Yet most Americans don’t know or care about
it, for the Ogallala cannot be seen with the naked eye but only by an educated
imagination. If you drive across
Nebraska heading for more gaudy treasures like Mount Rushmore or Grand Canyon,
you might notice huge green crop circles of corn and soybeans. An educated imagination might tell you that
these crops are being irrigated by water that lies beneath the ground’s
surface. And they are—water from the
Ogallala Aquifer.
And then if you knew the Ogallala contains approximately a
million billion gallons of water, which is to say about 2.9 billion acre feet
of water, you might begin to develop a sense of amazement about the Ogallala
Aquifer.
An aquifer, as you probably know, is not an underground lake
but something like a huge underground sponge—made up of water, sand, silt, clay
and gravel. The Ogallala is the largest
aquifer in the United States and one of the largest in the world. It covers 174, 000 square miles and stretches
beneath eight states, but 67% of its water is beneath the state of Nebraska. If the water of the Ogallala were ever used
up, it would take 6000 years to replenish it.
Ogallala-irrigated fields produce 15 % of America’s wheat
and corn, and 25 % of its cotton. But
this production comes at a cost to the aquifer, for the irrigation taking place
has diminished the amount of water in the aquifer to such an extent that some
experts predict the aquifer could be nearly used up in 2050.
The good news is that many farmers are learning to use the
water more wisely and frugally in order to sustain the life of the aquifer far
into the future, but changing attitudes and farming practices has been a slow
journey aided by technology, education, and hindered at times by a tradition of
over-use. The realization that the
Ogallala has already been exhausted by over-irrigation at some of its farthest
reaches has caused farmers to think twice about extravagant use of the water. Still,
much needs to be done to guarantee the future of the aquifer even as its water
is used more carefully.
But now there’s a new menace.
The Canadian government wants President Obama to approve the
building of a pipeline to carry sand tar oil from Alberta, Canada through the
heart of the United States—including Nebraska and the Ogallala Aquifer—and down
to refineries on the Gulf of Mexico.
Many American concerned about global warming oppose the
building of the pipeline arguing that the sand tar oil from Alberta is
unusually dirty and the use of it will only increase greenhouse gas emissions.
Supporters of the pipeline state that “the environmental
issues have been dealt with decisively by the final and fifth
environmental-impact statement by the U. S. Department of State.” Joe Oliver, Canada’s minister of natural
resources, goes so far as to say that “not building Keystone would increase
greenhouse gas emissions.” It is true
that the State Department report raises no major objections to the
pipeline. But it also acknowledges that
the proposed pipeline could accelerate climate change.
And so, as with many contemporary issues, we seem to have
two truths: the pipeline will increase
carbon emissions; the pipeline will not increase—but diminish--carbon
emissions.
President Obama continues to declare that our nation’s best
interest can only be served if the problem of carbon pollution is not
exacerbated by building the pipeline.
Meanwhile, some Nebraska farmers through whose farms the
Keystone is scheduled to pass, are protesting the pipeline for a reason that is
not related to carbon emissions and global warming. They know that pipelines break, and they know
that when the Keystone breaks, dirty oil will gush into their aquifer.
They have good reasons to fear a broken pipeline. In the last few months there have been three
pipeline breaks in North Dakota each one spilling thousands of gallons. In March 2014 an Ohio Forest Preserve was
awash in about 10,000 gallons of oil from a broken pipeline. A broken pipeline led to a spill of over
500,000 gallons of oil in Arkansas in 2013.
A pipeline spill allowed 42,000 gallons to flow into the Yellowstone
River in 2011. And the litany of broken
pipelines and dirty crude pollution could go on and on.
Of course the major argument in favor of the pipeline is
that it will generate jobs and wealth.
Sadly this is almost always the argument that wins the day, but I hope
that when President Obama makes his decision on the pipeline this summer, he
decides to do what’s best for the creation and for the America my grandchildren
and great-grandchildren will be living in.
I hope he considers not only the climate change issue but also the
broken pipeline issue.
I hope he has educated his imagination sufficiently to imagine two possible Nebraskas in the future: : A Nebraska alive with healthy communities and
growing things carefully watered by the waters of the Ogallala. And, a Nebraska dusty, bleak and barren, its
waters polluted by oil or exhausted by excessive use
