A borehole is basically defined as “a hole bored or drilled in the earth especially to obtain water.”
Processes involved in Borehole construction:
(i) Boring on the earth
(ii) Installing casing pipes
(iii) Installing gravel pack material
(iv)Well development
(v) Grouting
(vi) Pumping test/airlift
(vii) Sealing the borehole
(viii) Water sampling and testing
(ix) Water pump equipping
Water testing focuses on analyzing:
(i) Physical parameters
(ii) Chemical parameters
(iii) Bacteriological parameters
