In
the Kanjhawala the first clay & Kankar formation exists upto a
depth of 8m below ground level (bgl), which is followed by layer of
Kankar and silt which exists upto a depth of 24m bgl, which is followed
by impermeable layer of clay and kankar from 24 to 42m bgl.
A
comparative study of water level map of 1960 and 2002 shows in Kanjhawala
the water level which was at 2 to 5m below ground level has gone down
to 5 to 10 mts bgl.
In
Kankhawala the fresh water is of limited depth only. The area is dominated
by saline water aquifer. The amount of fresh water is decreasing due
to extraction.
| IV.RECOMMENDATION FOR AUGMENTATION
OF GROUNDWATER |
The
intake capacity of recharge structures will be low in shallow water
table condition. Hence in Kankhawala where the ground water level
is below 10m rainwater harvesting can be taken up.
