Large portions of this country experienced severe flooding
this past year, while other parts remained bone dry. Regardless of the
drenching rains in some areas, however, America’s aquifers are in serious
trouble. It takes literally decades to refill an aquifer.
According to Saving
Our Oceans, by R.L. Coffield, the United Nations predicts at least 30
nations will have water shortages by 2025. And by 2030, “47% of the world’s
population will be living in areas of high water stress.” That is nearly half
of the world’s population. Why? Aquifers are failing world-wide, including
those in the United States.
Rapid population growth, increased industrial demand, and
water withdrawals have tripled over the last 50 years. Water wars could well be
the future. Mark Twain once commented, “Whiskey is for drinking; water is for
fighting over.” If not water war skirmishes, mass migration of millions of
people from drought stricken countries will likely ensue which will cause
political and social upheaval.
Agriculture in general uses about 70 per cent of water
withdrawn from aquifers. The Ogallala aquifer, one of the world’s largest
aquifers located in the mid-west, lost a third of its water in just 30 years
due to farmers withdrawing water at an unsustainable rate. California’s Central
Valley aquifer is showing signs of depletion and could drop below reach by
2050. Because of the overuse of groundwater by farmers, many resident’s wells
are going dry.
Of the 37 major aquifers on the planet, 21 are on the verge
of collapse. Cities like Beijing, Shanghai, and Mexico City are sinking.
Indeed, sections of California’s Central Valley have dropped a foot, and in
some areas 28 feet. The facts regarding water shortage are dismal, but action
can be taken.
Water catchment systems are one of the simplest solutions to
water scarcity. Many dry areas, like Texas and Arizona, are now allowing
rainwater-catchment installations on homes and other buildings.
In addition, desalination has become well known in recent
times. Desalination can work not just for salt water, but for water considered
“brackish,” which is water that is too salty for human consumption. There is up
to 10 times more brackish water than freshwater in any aquifer. And changing
from highly thirsty, water intensive crops, like corn , cotton, rice, and wheat
to less water consuming products might also be a consideration.
But the most extreme measure, in many people’s minds, is the
concept of “Toilet to Tap.” Namibia, a very arid country has been purifying
wastewater into drinking water for almost 50 years. No one has ever become ill
from this “reused water.” In 2003 Singapore began treating sewage water to
drinking-water standards, and now El Paso, Texas, is preparing to provide
potable reuse water for drinking. This is because El Paso’s Hueco Bolson
aquifer that has supplied El Paso with water for decades could run dry which,
at its rate of drop, could happen by 2025.
Unfortunately, much of the currently available water for
consumption is contaminated. The drinking
water of 233 million Americans is
dangerously compromised.
As deadly serious as the prospect of water shortage and
contamination is, it’s surprising that this issue is not front and center.
There’s much more to this story, however, and it’s covered in Saving Our Oceans by R.L. Coffield.
