Why People Live Their Lives By Getting In The Back Of Trucks Illegally To Make A Livelihood

Just curious as to what the average depth there is to reach groundwater via digging wells. There has got to be a logical reason why wells powered by old fashioned hand pumps are uncommon there. Wells have been dug without special tools for thousands of years even in mountainous regions. There is a very deep well on my families property that was tapped by hand back in the 1860’s, it still produces clean water by an old hand pump to this day
