re: Louisiana Is Running Dangerously Short Of Groundwater

Sure if you can wait 10-100+ years for the water pumped to the surface to make it back to the aquifer, and be willing to lose runoff, evaporation, etc. Anywhere you have highly concentrated ground water pumping is going to suffer a net loss in the aquifer over time. It is being pumped MUCH faster than it can be replenished.
Aquifers are generally under an impermeable layer that keeps local water from reaching it. For example, the Sparta Aquifer, which supplies most of Northern and Central Louisiana, is covered by a layer of clay everywhere but in one section of Webster Parish, where the Sparta sand reaches the surface. This one area recharges the whole aquifer. Everywhere else, water pumped out runs off or evaporates.
The contrast is even more start out west. The Ogalalla Aquifer supplies large parts of the Great Plains with agricultural water. The water in the aquifer is millions of years old and under a thick layer of rock. Pumping water from it is similar to pumping oil from an oil deposit. It's never going to be replaced.

Right. Like the hypothesis that by 2000 nations would be under water from sea level rise caused by global warming

You're leaving out a major chunk of the process and jumping to conclusions. There is a lot of the potable water we consume that comes from sources that you wouldn't just walk up to take a drink. But it's processed and made drinkable (potable water). I happen to work in a plant in which the potable water comes from the Mississippi River and is filtered.
Damn near ALL the potable water is treated in this country.

And let's take it a step further than that. Water can be be man made fairly easily. And then that water could be filtered and made drinkable. Of all the resources that we consume on this planet, water should be dead last on the list of things to be concerned about.
We have developed and employ the technology all offer the world to clean water. Some places there just isn’t a lot of water. Think the eastern part of Cali

I have read for decades about aquifers running dry.
My question is, with the Mississippi River going though seasonal flooding, why hasn’t a goodly portion of that been diverted to a newly constructed reservoir and then injected into the depleted aquifers? This isn’t my area of expertise, but don’t injector wells reach some pretty impressive depths?

Some regulation does have a place.
I agree, and I like to consider myself a supporter of as small a government as possible. Water and air pollution are two things that needed protection. Reducing sulfur emissions was a good thing. The clean water act was a good thing.
Governments abuse of “we are just protecting you. We know what’s best” is what scares me.
But right now most of the regulations are geared towards industry despite 61% of Louisiana aquifer water use coming from agriculture. Regulating and taxing the shite out of industry isn’t gonna stop aquifer depletion.

read somewhere that the wells in the Baton Rouge Exxon refinery produce/use more water than all of the rest of the parish in its entirety and that this is a contributing factor to salt water intrusion in the aquifer.
I’d like to see that linked as I understood a lot of plants were barred from using aquifer water due to salt water intrusion concerns. Not saying exon isn’t using it, but I thought they were one of the plants that was no longer allowed to use it.

Here you go. Exxon claims it’s using half from the River and half from the aquifer. And it would be pretty easy to transfer all except drinking water to the River. Give Exxon an ITEP and let them convert.

What area do you suggest flooding?
Louisiana is on the brink of dehydration, draught and unrelenting crawfish inflation and you worried about flooding?

Orange grove irrigation in Florida says hold my beer.
I know of chemical plants along the Mississippi River that pump thousands of Gal / min of ground water for cooling. 72 deg F ground water provides better cooling in summer than 90 deg F River water. Regulating the use of (drinkable) ground water for cooling is maybe worth considering. The Norco aquafer is finite.

Lol! Not in North Bossier, ground water has risen substantially, due to all the neighborhood development.

Their flow diagram that's part of the public record shows they draw about 14 million gallons per day from wells.
eta: Here is an opinion from the other side. As in we won't be drinking salt water from the aquifer any time soon.
LSU researcher: Southern Hills Aquifer has ample supply; salt water intrusion no crisis
quote:
Carlson's analysis found all the water-bearing sand layers in the part of the Southern Hills Aquifer under East Baton Rouge had between 3.4 trillion and 15.4 trillion gallons of water of good enough quality to be used. That could supply centuries of water under current pumping rates.

Man the sarcasm and genuine lack of concern in this thread is worrying. I've sat in on a few groundwater committee meetings thinking I was going to go in and raise hell and it ended up being some of the sharpest minds from LSU geology, Water Chemistry and Ecology professors. I was blown away and the information they have (and publicy present!) is fricking terrifying. Baton Rouge water company had already purchased waterfront property on the Amite and Comite rivers to set up filtration and pumping stations for when we dry up/start pumping salt from the sand hills aquifer. I know for some reason logic seems to get downvoted but it is a VERY real possibility that our drinking water will be from the rivers sometime within the next 20-30 years. Everyone is to blame, residents that don't fix leaks, ExxonMobil and Georgia Pacific using aquifer water instead of river water, farmers using well water instead of bayou water....Everyone is laughing now but this issue is worldwide. Anyone interested should check out "When The Rivers Run Dry" Gives accounts from around the globe about ongoing and future water crises'

So is this where JBE going to insert his next tax?
I’ll wait and see what Dr Falsesy thinks.
