State Profile 

Ground Water Scenario of Jharkhand

Area (


Rainfall (mm)


Total Districts / Blocks

24 Districts


The State is underlain by variety of rock formations from Pre-Cambrian to recent age. A major part of the State is underlain by formations comprising of granites, granite gneisses, meta-sedimentaries and a variety of volcanic rocks. The volcanic formation represented by Rajmahal traps are exposed as patches in a linear fashion in the north-eastern part. The sediments belonging to Vindhayan system are seen exposed in the north-western part of the State. The lateritic capping is invariably seen in the south western part. Recent alluvial formations are mostly confined to the valleys along major rivers of the State. The ground water exploration   has revealed presence of 3 to 4 potential fractured zones at variable levels within a depth of 200 m from the ground level. The discharge of the exploratory wells is highly variable ranging between 3.6 to 54 m3/hr. In some of the pockets higher discharge wells has also been constructed.
