Challenges and Way Forward
The key groundwater management issues are the following:
The area suffers from over exploitation, with a water decline of more than 4 meters from 1998 to 2008. The stage of groundwater development in the district is 158%.
The area suffers from fluoride contamination and salinity at places.
Challenges and way forward for aquifer mapping in the area are the following:
As shallow aquifers in the alluvium get dried up, delineation of deeper productive alluvial aquifers and of aquifers in the fractured zones of the hard rocks is becoming essential.
The electrical resistivity method has got limitations in delineating thin alluvial aquifers and fractures in the bed rock at depth. Therefore, a combination of geophysical techniques is required.
Delineation and determination of potentiality of deeper aquifers in the alluvium immediately overlying the bed rock is to be carried out.
The exact bed rock topography needs to be ascertained.
The groundwater potentiality of fractured zones in the hard rocks is to be ascertained.
Complete investigations will be required in the central and eastern parts of the area, which have remained relatively unexplored until now, due in particular to the presence of ravines and non-approachability of drilling machines.
Aquifer parameters and recharge and discharge processes have to be studied for all aquifers and sustainable abstraction levels precisely assessed.
Chemical quality of all aquifers needs to be ascertained.
Development of an Aquifer Information System on aquifer geometry, ground water availability and its chemical quality in space and time is needed for improved ground water management and regulation practices.
Aquifer mapping will provide the scientific basis for improved and more sustainable groundwater management in the area in partnership with stakeholders, in particular by identifying alternative resources that could be put to use, ascertaining sustainable abstraction levels, and identifying areas with poor groundwater quality.
