Aquifers provide us freshwater that makes up for surface water lost from drought-depleted lakes, rivers, and reservoirs. We are drawing down these hidden, mostly nonrenewable groundwater supplies at unsustainable rates in the western United States and in several dry regions globally, threatening our future.
We are not as adept when threatsor threatened resourcesare invisible. Some of us have trouble realizing why invisible carbon emissions are changing the chemistry of the atmosphere and warming the planet. Because the surface of the sea is all we see, it's difficult to understand that we already have taken most of the large fish from the ocean, diminishing a major source of food. Neither of these crises are visiblethey are largely out of sight, out of mindso it's difficult to get excited and respond. Disappearing groundwater is another out-of-sight crisis.
Groundwater comes from aquifersspongelike gravel and sand-filled underground reservoirsand we see this water only when it flows from springs and wells. In the United States we rely on this hiddenand shrinkingwater supply to meet half our needs, and as drought shrinks surface water in lakes, rivers, and reservoirs, we rely on groundwater from aquifers even more. Some shallow aquifers recharge from surface water, but deeper aquifers contain ancient water locked in the earth by changes in geology thousands or millions of years ago. These aquifers typically cannot recharge, and once this "fossil" water is gone, it is gone foreverpotentially changing how and where we can live and grow food, among other things.

(1,893 posts)Groundwater Depletion Linked to Rising Sea Levels
Large-scale groundwater extraction for irrigation, drinking water or industry has resulted in an annual rise in sea levels of approximately 0.8mm - this works out at one quarter of total annual sea-level rise (3.1mm). The remaining total can be attributed to thermal expansion (50%) and run off from glaciers and ice caps (25% approx.).

(8,127 posts)as those who lost water move to other locations with a limited source as well.. so then that source fails more quickly.. now all of them move to the next source .. and so on and so forth...

Erich Bloodaxe BSN
(14,733 posts)Which is yet another reason why many in the 1% want to keep the rest of us poor. They can see the writing on the wall, and it's only human nature to want to keep scarce resources for yourself and those close to you. It would be better for all, though, if they would help instead to move us to ways that help make sure those resources don't become scarce in the first place, such as not polluting our aquifers while trying to become 'energy independent' by fracking for natural gas.

(22,631 posts)Detrimental to the water supply. We have been industrialized not only as evidenced by the militarized police but in the loss of connection between ourselves, the land and food. But then land isn't necessary for farming either. Food is fuel. The farm should be a pharmacy.

(35,648 posts)Should have been implemented a long time ago. Farmers are slow to adopt, but incentives should have been offered. The amount of waste with other forms of irrigation (such as center pivot) is something like 70 per cent lost into the air.
Furthermore, plants thrive with drip irrigation.
In this picture, you can see the air dispersing into the air.
How simple is that? !?!?!?!?

Water that goes into the air falls to the ground.

(35,648 posts)Hey, 'yer talking to a former Nebraskan. I know center pivot. I grew up around it.
It wouldn't be hard to innovate a drip system to accommodate any type of crop.
I don't believe you're correct about it falling to the ground. I've read otherwise.

(17,184 posts)So conservation efforts are just an attempt to push the inevitable off onto another generation. It would be useful to find some alternatives before the crisis occurs, but people seem to be innately reckless about their use of non-renewable resources.

(8,203 posts)just this past year AZ WRD approved another well for a golf course - I am on record with our city water dept. as well as the AWRD - why not use "reclaimed" water? (some do, I will say, but not ours) - our city water manager is knowledgeable and on record basically saying "we may not have a crisis yet, but is just a matter of time - she (city water manager) doesn't have any power over the state...I just say "HELLO" - is anyone listening?

(15,480 posts)When roughs were really roughs, golfers carried their own clubs and didn't ride in golf carts, and the greens were not watered and manicured to have the consistency of green velvet.
A few years ago, the World Water Forum designated the US as the most wasteful water user in the world. And the key reason given for this liquid licentiousness? No, not all those super-sized sodas. Not the profligacy of back-garden swimming pools. Not leaving taps on during lengthy teeth-whitening sessions. No, the key culprit was golf.
Then there are all the motorised golf carts, plastic balls mishit into woods and off cliffs into the sea, and the fact that few courses are well connected with public transport - the sight of a golfer on a bus with his clubs must be rarer than a round of hole-in-ones. It all adds up to an uncomfortable dilemma for the golf-loving green worker. If your happiness, your business deals or your stress management relies on a regular round of golf, what can you do?
Firstly, choose your course wisely. A course designed and managed with respect for the natural environment can actually have ecological benefits, such as providing natural wildlife habitats and corridors in or around urbanised areas. While there is no recognised green label for golf courses, hundreds in England and Scotland have signed up to national initiatives such as Golf Environment Europe to improve their environmental impact. Ask your local course about its green policy, and if the manager looks at you like you are a mad, woolly leftie who needs chasing away with a nine iron, consider taking your checked trousers elsewhere.
If you are heading off on a business trip somewhere hot and dry - such as Las Vegas - then think twice about packing your clubs. At least in the UK we have lots of rain to help keep the fairways green, but in countries such as Spain or Dubai golf courses can often use more water than a small town.
To ease your emissions that little bit extra, decline the golf cart and get some exercise, and pack some biodegradable golf balls and environmentally friendly tees.

(3,747 posts)I know the coast is wetter (been rained on enough that I figured it out ), but I still don't get the negative groundwater depletion. Does that mean groundwater has increased in those areas? As in filled in again? Or does it mean something else entirely?

(28,791 posts)NE corner of Colorado..
Growing up our water tasted so pure, we would pack 5 gallon tanks of it to take up to the mountain cabin cause the water in Fort Collins tasted worse.
Now, everyone in town has to filter the water, it's horrible.. so laced with minerals that it's undrinkable and it ruins coffee pots and dishwashers. All the good water is gone and they're drinking the dregs of the aquifer.
I'm 45 now, and the water was fine when I left in my 20's. It makes me so sad.

(32,723 posts)The West could be a garden with the excess water from the East.
And before someone says there is no "excess water",...oh sure,...none of the fresh water from the Mississippi makes it to the sea.
IDemo
(16,926 posts)That argument was brought up in the early 90's by a Los Angeles politican who proposed an aqueduct from the Snake/Columbia river system to supply California's water needs. His reasoning was that water was "wasted" if any remained at the mouth of the Columbia. He was promptly corrected.
Besides the fact that migrating fish rely on the flow of water to make it from the ocean to spawning grounds and allow their offspring to make the reverse voyage, a certain minimum flow is necessary to maintain cooler temps and oxygen levels in the water.
Rivers also serve to replenish ground water and to supply the populations surrounding them with drinking and agricultural water. Any water management official would take vigorous exception to the notion of 'wasted water'.

(16,926 posts)Do we want to spend billions on constructing the ditches, pipelines, canals and pumping stations to gather water that cannot be relied on to be in the same place or in the same quantity from year to year? While there is no argument that a significant amount of water exists at any given instance of flooding, it doesn't reliably find itself flowing into major (or even minor) river systems. And even if we did build pipelines East to West, it takes an enormous amount of energy to move that water, energy which would be better used for desalination.
