underground water detector

[surf-tech]

Hello everyone
This topic may be of interest to some. I hope the idea of groundwater detection devices is accepted. If anyone has any information to share or plans for a device we can study and build, I need more information.

I successfully found a water pipe at a depth of 2 meters with this device. On the first try.

You will probably find there is not much interest here in groundwater detection. I know little about it, but I do know there are two devices that can be used that are fairly easy to build: resistivity and induced polarization. A good 4-probe resistivity meter with data logging was published in EPE magazine (April-May 2003). I don't have an IP design to recommend but it works similarly to a PI detector but with voltage probes instead of coils.

That's the "million dollar" question (actually much more).
Water becomes more valuable than gold and other precious metals.
Climate change (not the one forced by the media) and the shift of the poles of the planet; are the main cause of "displacement" of water courses.
One would think that it is about cataclysmic changes, but it is comforting that this is not the case. These are normal cyclical changes that the planet goes through every 8-11k years.
And what we now have as a consequence; water "moves", disappears from the place where it existed and appears in places where it was not there before.
This would not be a big problem if humanity did not develop precisely on the basis of the presence of water. Settlements stood first in places where there was water.
Over the centuries, larger and larger urban centers have sprung up there. That's why we have a problem today!
That's why the problem of locating water deposits in depth will become more and more relevant as time goes by.
And in some areas of the planet, water will become (already is) a very expensive and important resource!
I live in Serbia, which is very rich in natural drinking water. We never had a problem with water.
And then in 2004/5 I stayed in Malta and there I saw something that shocked me!
Malta has no drinking water! Not a bit! Drinking water is imported from Italy, primarily from nearby Sicily.
And the rest of the need for "technical" water is covered by modern seawater purification and desalination technologies.
In Malta, I paid for water for the first time in my life!
That was a shock for me.
Until then, I thought of water as something that was cheap and ubiquitous, and I did not realize the vital importance of water.
It was only in Malta that I started seriously respecting water and realized all the advantages of living in my country where we don't have that problem.
But that was 2004/5 which somehow coincides with noticeable changes in water flows and with my personal interests in magnetometers and resistivity meters.
Upon returning home, for the next few years; I began to notice how some old springs are disappearing, drying up and how the water is slowly being lost and coming down from the mountains into the valleys.
As a "treasure hunter" it is logical that I have long been collecting maps, charts, etc. 90% of the water sources from those maps no longer exist today! What does that say?
It is about decades to a couple of centuries, it is not about a duration of a thousand years or more.
In my "expeditions" I discovered that water descends from the heights to the lowlands...
for example; where there was a source of water on the map, 100 years ago: today it is dry and the next water can usually be found a few hundred meters to even a few kilometers below that point.
Everything written so far shows that water will become a very expensive and rare resource in the near future.
To avoid confusion, I am talking here about natural drinking water, which does not need any purification, I am not talking about water as matter, which is always present on the planet in same quantity.
So... the question from the first post makes sense and becomes very important!
Maybe it's time for this forum to deal with this kind of technology and not to continue wasting time on pointless metal detectors, which are a very limited technology in which everything has already been said.

Thank you Mr. Ivconic, you summed everything up and it is really shocking. Fresh water is decreasing at a very alarming rate according to several statistics and studies. You have experienced it, but we have been living it for years when you have the equipment and are forced to dig wells to depths of 100 meters or more and you find that the water in most of the wells is salty, especially in the cities near the sea. Thank you for your response and for all your contributions here in the forum.

Some time ago I was interested in ground water exploration and I researched nuclear magnetic resonance imaging method. I read whatever I could find as there wasn't a lot of information freely available. I never tried building such a device because I found it too complicated and crazy expensive. In addition, the interference from power lines located even a few kilometers away exceeds the faint signal from ground water. It requires huge amounts of power and would likely work only in very remote locations.

What I will suggest you to look at and consider will not give you concrete answers.
Why? Because I'm looking for similar answers myself.
I still don't have a good answer.
However, a couple of years ago I developed a theory that seems to me to be going in the right direction.
I'm not going to go public with the theory because everything is still on a very long stick.
I think it's more productive to "sow crumbs" here and there... and see if there will be someone persistent and perceptive enough to follow the clues.

Ivica ... are you not aware of technology solutions that can produce as much pure water as you require ? Underground water resources are exactly that .. they are resources and almost invariably they are abused by overpumping / pollution as soon as they are discovered and you cant rely on finding new sources. So a detection means might have been useful in 1960 ... but in 2060 will be ???

Cheap desalination is where the money is at. Now, what to do with all that salt?

use it for cooling molten salt or liquid sodium nuclear reactors that power the desal plant.

Paul...I understand very well what you were trying to say in the previous post...unfortunately, you are 100% right and I agree.
Paul... I've been struggling with you for years!
My altruism has no chance against your pessimism!

Hello Karl-NC
Maybe you are describing this.

[kt315]

with the Holy Mantra from the Holy book on your lips... you will find the water.

Sorry, I don't know what that is.
