In this lesson we are going to discuss about the artesian well

Answer Text:
Artesian well
Well sunk into the aquifer of an artesian basin from which water will come out without being pumped.

Ideal Conditions for Formation of an Artesian Well
a) Aquifer to be sandwiched between impermeable rocks to prevent evaporation and percolation.
b) Aquifer to be exposed in a region which is a source of water e.g. rainy area or lake.
c) Aquifer to dip from the region of water intake.
d) Mouth of the well to be at a lower level than the intake area to develop hydraulic pressure which will force water out.

Problems Associated With Artesian Wells
a) Water may be hot due to high temperatures.
b) Water may be salty because of water taking long to percolate through rocks thus dissolving large quantities of mineral salts.
c) Water may fail to come out naturally when water is drawn faster than it’s being replaced in the source region and
necessitating pumping.
