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.
