In
the Alipur the first sand formation exists upto a depth of 12m below
ground level(bgl), which is followed by layer of Kankar and silt which
exists upto a depth of 16m bgl, which is followed by impermeable layer
of clay and kankar from 16 to 20m below ground level. This clay layer
is followed by layer of Kankar and silt upto 50m depth
A
compartive study of water level map of 1960 and 2002 shows in Alipur
the water level which was at 2 to 5m below ground level has gone down
to 5 to 10 mts below ground water level.
In
Alipur the occurrence of fresh water in alluvium formation is upto
a depth of 30m to 60m. 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 Alipur where the ground water level is below
10m rainwater harvesting can be taken up.
