Piezometric water-level conditions in Bangalore city, Karnataka, India
Earlier works have revealed that Bangalore city predominated by migmatites, granodiorites and intrusive granites, in general does not carry potential fractures beyound 280 m depth. However, bore wells are being drilled in the peripheral parts beyond 300 m. This unconfined and part of the semi-confined aquifers having gone dry, bore wells are now being competitively drilled at greater depths.
