Feaibility of ground water bearing potential Each aquifures at shallow/Depper depths for sinking of successful shallow/Deep tube well in an area. Surface Geophysical investigation (Resistivity) tests by schlumberger configuration followed by Ohm's Law must be carried out which will help with maximum accuracy of the sub surface results at minimum costs and in short duration. This technique will infer (a) the thickness of the top soil/over burden, (b) thickness of weathered rock, (c) Depth to the bed rock, (d) Vertical extention of the aquifures/fractures at the test spot at shallow and depper depths and their potentialities and (e) recommendation for the drilling depth at the selected feasible site. In this test only the availability of ground water i.e. hte potentiaties of aquifers/fractures can be told along with depth to be drilled minimizing the drilling cost, towards constuction of deep tube well.
