sad but interesting facts about water [updates]
So a few days ago I noticed the article of "Women Still Carry Most of the World's Water." And that got me thinking, there are a few ways to solve this problem. First, there is the idea that we can help them carry he water back and forth not eliminating the problem entirely but taking some strain off the people. Or we can possibly find them a new source of water that doesn't need them to walk miles and miles. So I thought maybe groundwater?
So this is by no means scientific analysis, but here are some maps from google (not reputable sources yet).
The top maps are of precipitation and water strain respectively. The bottom maps are labeled. But what's interesting is the comparison (assuming these maps are accurate). Comparing them shows many areas where there is high water strain in areas with low precipitation and not necessarily deep groundwater (groundwater may be shallow) but where ground water STORAGE is low. There is one interesting area though.
This area is interesting. We NEED to do more research but if these maps are to be believed. This is an area with HIGH water shortage/strain, and it's an area with low levels of precipitation, and it's an area where groundwater is DEEP, but groundwater is highly abundant. Now I don't know the quality of the water here, but this could be something to look into. Have people targeted this area? Is the water there safe to drink? Can we install very deep wells in this area?
I don't know the answers to these questions but they're worth looking into and there are definitely people looking into them:

So now I want to know how do we find groundwater and there are many techniques, let's start with the TWO EXTREMES. (1) https://sciencing.com/surface-subsurface-water-resources-22528.html finding using visual clues.
- More likely in depressions in the land/valleys or hills
- "Rocks are the most valuable clues of all. consolidated formations such as sandstone, limestone, or granite as well as for loose, unconsolidated sediments such as gravel or sand. An "'aquifer" is any body of rock that contains a usable supply of water. A good aquifer must be both porous enough to hold water and permeable enough to allow the continuous recharge of water to a well.
Gravel, sand, sandstone, and limestone are among the best aquifers, but they form only a fraction of the rocks in the Earth's crust. Most rocks are fine grained or otherwise '"tight" and store or carry little water."
This is the other extreme, "NASA Satellite Data Help Show Where Groundwater Is – And Where It Isn’t."
But what if we need a more local solution? From a village perspective where is the water located in this specific village, how much is there, how do we get these set of farms water? What if we wanted to start answering these questions on a more local level?
Well hopefully the answer to that questions is INEXPENSIVE TECHNOLOGY:
This is an example of Ground Penetrating Radar systems that can be used to create MAPS of the ground. The data from these kind of systems could be invaluable in determining where to place wells or where to find springs and such.
Desalination and other technologies like technologies that allows us to take brack water and turn it into usable fresh water.
