State Profile

Ground Water Scenario of Goa

Area (Sq.km)	3,702
Rainfall (mm)	1999
Total Districts / Blocks	2 Districts/11 Talukas

Hydrogeology

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 are in general more than 108 m3/hr in alluvium and less than 36 m3/hr in other formations.
