From Toilet to Tap – Are you Ready?

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.

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, then mass migration of millions of people from drought stricken countries will likely ensue which will cause total 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Agriculture in general uses about 70 per cent of water withdrawn from aquifers.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 in any given area. 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 most 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 water currently available for consumption is contaminated. nrdc.orgThe 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.

Aquifers Around the World Are Going Dry

India’s 6th largest city is struggling with a depleted aquifer, and it is far from being alone. Despite the cataclysmic amount of rainfall parts of this country received this year (and many areas are still getting deluged) depleted aquifers are a serious threat worldwide.

According to Saving Our Oceans, there are 37 major aquifers on the planet. Of this number, 21 are on the verge of collapse. Beijing, Singapore, and Mexico City are literally sinking. Closer to home, El Paso Texas is now preparing for “toilet to tap” potable water due to the Hueco Bolson aquifer potentially running dry by 2025.

The technology already exists to treat human wastewater to drinking water standards, but for obvious reasons doing so has a poor public image. Other areas do this, however, and no one has ever gotten sick from the treated water.

In the mid-west which has one of the world’s largest aquifers, the Ogallala, a third of this aquifer’s water was used in only 30 years, largely by farmers withdrawing water at an unsustainable rate. California’s Central Valley aquifer is also showing signs of depletion.

And in southeast Arizona large corporations have bought up thousands of acres of land, drilled countless wells and are “groundwater mining,” withdrawing water far faster than it can be replenished.

Agriculture in general uses about 70% of water withdrawn from aquifers.

One rainy or snowy winter does not solve years of overuse. It can take decades for an aquifer to recharge.
