underground.water.univeristy.victoria.texas.running.out_occupycorporatismResearchers from the University of Victoria and the University of Texas at Austin (UTA) have devised a map of all the known source of underground water on earth which details where and in what quantities this resource can be found.

To come up with this much detail, the team analyzed databases of an estimated 1 million watersheds and combined that with 40,000 groundwater models.

According to their conclusions, there is a total of 23 million cubic kilometers of underground water. The majority of this water is buried in subterranean aquifers which is used in areas where surface water is scarce.

The problem with the findings is that 6% of the groundwater in the upper 1.24 miles of the earth’s surface is renewable within one human lifetime.

Older water, located deep within the earth, is saltier than ocean water and contains arsenic and uranium. This is considered a non-renewable source.

Modern water is located closer to the surface and therefore vulnerable to changing climates and contamination. This renewable source is being consumed by humans faster than it is being replenished.

The majority of the earth’s modern water is located in tropical and mountainous regions such as the Amazon Basin, the Congo, Indonesia, and the Northern and Central Americas.

Tom Gleeson, professor at the University of Victoria, revealed in a 2010 study : “Groundwater extraction has facilitated significant social development and economic growth, enhanced food security and alleviated drought in many farming regions. But groundwater development has also depressed water tables, degraded ecosystems and led to the deterioration of groundwater quality, as well as to conflict among water users.”

Back in June, researchers at the University of California at Irvine (UCI) determined that not only are groundwater resources depleting, but underground aquifers are threatened by stress levels in the global groundwater basins.

To replenish them would take just as long and UCI researchers contend that consummation is at an ever increasing rate which is impacting the earths “water savings account”.

The first study details the known 37 large water aquifers mapped from 2003 to 2013. Of those:

• 8 were deemed “overstressed” because there was no known replenishment source
• 5 were found to be “extremely or highly stressed because there was notable small replenishment sources
• The driest aquifers were in the direst areas above ground as well

The areas identified as having the driest aquifers include:

• Iraq
• Saudi Arabia
• Yemen

The Arabian Aquifer displayed signs of overstress which is threatening 60 million people who live in this part of the world.

Socioeconomic and political tensions in highly stressed regions are actually causing the exacerbation of the depletion of underground water stores.

In the second study , researchers surmised that the amount of useable groundwater is questionable because predictions of the depletion made decades ago are not evidenced by satellite imagery.

In fact, the depletion in many aquifers is much less than previously thought. But estimates now have to confirm to determine exactly “how much is stored in each of these aquifers.

The researchers guess that “estimates of remaining storage might vary from decades to millennia. In a water-scarce society, we can no longer tolerate this level of uncertainty, especially since groundwater is disappearing so rapidly.”
