GROUND WATER MONITORING

We collect data to determine the amount of groundwater that can safely be withdrawn before no more water can be pumped. 

Monitoring of depth to water in phreatic aquifer and piezometric head in the deeper confined aquifers, in time and space, is a very important activity in the estimation of ground water resources and their change with time. Study of pressure heads in each individual aquifer of the multi-layered aquifer system is very important to understand the ground water movement across the system. From the well inventory, representative wells tapping the phreatic aquifer are selected at a close interval for monitoring. Piezometric heads are measured from existing / purpose-built piezometers. Some of the monitoring wells are fitted with pressure transducers to record continuous change in the pressure heads. The differences in the phreatic and piezometric heads and their variation are analyzed to understand the ground water flow pattern along and across the aquifer units.
Based on the processing of data from well inventory, monitoring and the field observations, ground water high stress areas and vulnerable areas are identified.
