In
the Haiderpur the top Kankar and silt formation exists upto a depth
of 20m below ground level (bgl), which is followed by impermeable
layer of clay and kankar from 20 to 28m below ground level. This clay
layer is followed by layer of Kankar and silt upto 50m depth.
A
comparative study of water level map of 1960 and 2002 shows in Haiderpur
the water level which was at 2 to 5m below ground level has gone down
to 5 mts below ground water level.
In
Haiderpur the occurrence of fresh water in alluvium formation is upto
a depth of 30m. Below that level saline or brackish water occurs.
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 Haiderpur where the ground water level is
below 10m rainwater harvesting can be taken up.
