8. Conclusion
The spatial and time variant changes of groundwater quality are assessed through graphical representations. The
predominance of chloride ion in certain areas reflects greater residence time of groundwater. The present study
reveals that the influence of geological (geogenic) conditions is found to be more than the anthropogenic activities
and supports the increasing concentration of physico-chemical characteristics in groundwater. The factors like slow
circulation, longer period of contact between aquifer and water, dissolving of minerals at the time of weathering,
residential time, drainage pattern and surface water link are the main factors are responsible for the vary in chemical
