Pick up the incorrect statement from the following :
An impervious layer a few metres below the water table in the sub-soil, is generally called Mota layer (6) Mota layer is very useful to give structural support to open deep wells
A bore hole is generally provided in the mota layer for deep wells
Shallow wells are always of less depth as compared to deep wells
None of these.

Option C is also incorrect because the classification of deep well and shallow well is not based upon depth it's based upon discharge so shallow well can be deep as compared to deep well.

Option C is incorrect as this terminology has nothing to do with depth. Sometimes shallow wells have more depth than deep wells.

0ptiin C is incorrect because deep well may be less deep than shallow well.

Guys there is difference between foundation and wells.

Shallow well water is obtained above the first impervious layer while the deep well water is gotten below the first impervious later.

Shallow wells yield moderately hard water unlike deep wells.

Shallow well gets grossly contaminated unlike deep wells.

Shallow well is about 2-3m into the aquifer Answers are correct.
