GROUND WATER MEDIUM (Hydrogeological Conditions)
The state is covered by rocks of Dharwar Super group and a small patch of Deccan basalts are overlain by quaternary alluvium. Ground water occurs under unconfined and semi-confined conditions in beach sands, laterites and weathered and fractured crystalline rocks. The yield prospects of ground water is in general more than 108 m3/hr in alluvium and less than 36 m3/hr in other formations.
