The following maps can be found on the Central Groundwater Board (CGWB) website. Taylor outlined eight groundwater provinces of India, based on sedimentary and non-sedimentary rock types, 1) Pre-Cambrian Crystalline Province; 2) Pre-Cambrian Sedimentary Province; 3) Gondwana Sedimentary Province; 4) Decan Trap Province; 5) Cenozoic Sedimentary Province; 6) Cenozoic Fault Basins; 7) Ganges-. The aquifers are classified into 14 Principal aquifer systems, which in turn have been sub - divided into 42 major aquifer systems. In an earlier classification.

Quartzites and marbles are poorest in water resource. It is patchy, confined to the Cuddapah and Vindhyan basins of sandstone, conglomerate, limestone and slate. Well-compacted and non porous sedimentary strata are least favourable for ground water resource. Isolated basins of the Barakar and the Godavari, surrounded by crystalline rocks, have good aquifers in sandstone, but poor in shales.

It encompasses some of the world's largest fluvial systems groundwater provinces of india the world River Brahmaputra, Ganges and Indus Basinswhich hosts some of the highest yielding aquifers in the world.

Groundwater Maps - India

The distribution of usable groundwater in the region varies considerably and the continued availability of safe water from many of these aquifers e. The topography and rainfall virtually control runoff and ground water recharge.

The high relief areas of the northern and groundwater provinces of india regions, the Aravali range groundwater provinces of india Rajasthan, and peninsular regions with steep topographic slope and characteristic geological set-up offer high run-off and little scope for rain water infiltration.

The ground water potential in these terrains is limited to intermontane valleys.

Ground-water provinces of India | Economic Geology | GeoScienceWorld

The large alluvial tract in the Indus-Ganga-Brahmaputra plains, extending from Punjab in the west to Assam in the east, constitutes one of the largest and the most potential ground water reservoir in the world.

The aquifer systems are extensive, thick, hydraulically interconnected and moderate to high yielding. To the north of this tract, all along the Himalayan foot hills, occur the linear belt of Groundwater provinces of india piedmont deposits, and the Tarai belt down the slope with characteristic auto-flowing conditions.

Almost the entire peninsular India is occupied by a variety of hard and fissured formations with patches of semi consolidated sediments in narrow intracratonic basins. Rugged topography, compact and fissured nature of the rock formation, combine to give rise to discontinuous aquifers with limited to groundwater provinces of india yield potentials.

The near surface weathered mantle forms the all important ground water reservoir, and the source for circulation of ground water through underlying fracture systems. Lower Gondwana is compact and it is devoid of water because source rock is compact shale.

groundwater provinces of india Upper Gondwana sediments form very good aquifers, because those are more arenaceous. Water table lies generally within 30 m. Age ranging from late cretaceous to early Eocene.

The flows are flat but dip of 5 o to 15 o is also seen in some places.

8 Classification of Ground Water Provinces in India by Dr. R.L. Singh (1971)

The traps have groundwater provinces of india divided into three groups viz. The occurrence of "red boles", which is reddish brown clayey material, water bearing causes problems during drilling. Ground water occurs under water table conditions in weathered and jointed traps.

Bore well drilled in traps have given higher yield mostly trapping 2 or more flows. At places the contact between the traps and the basement rock have yielded considerable quantity of water.
