In hard rock terrain‎,‎ shallow water wells generally have a poor to moderate yield‎.‎ Sinking wells deeply to tap yielding fracture zones often backfires‎,‎ because the borehole may miss the saturated fracture zones at depths‎.‎ A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste of time‎,‎ something that could have been avoided by a systematic and proper geophysical approach‎.‎ The combination of various geophysical techniques with environmental conditions is essential to constrain the interpretation and reduce uncertainties in this respect‎.‎ This book presents the approach to groundwater exploration in hard rocks‎,‎ various geophysical techniques and combinations to be used‎,‎ interpretation of data with case studies and drilling results and the preparation of different utility maps‎.‎
