The quality of groundwater in nature is determined
by quantum and nature of recharge, chemical
composition of the soil cover and its thickness,
mineralogical make up of the aquifer, residence time
of the water which is governed by the transmissivity
of the formation. The two important characteristics of
the crystalline terrain, which covers practically the
entire Taluk, are the heterogeneity and preferred
flow paths. They have a dominant role to play in
determining the quality of the ground water with the
result; large variations are noticed in short distances.
Thus it is not uncommon to get varied quality of
water even in a small village. This fact is to be borne
in mind while locating sources of water supply for
various uses
