Electrical Conductivity of Lake Water as Environmental Monitoring – A Case Study of Rudrasagar Lake

The development in water quality monitoring has improved considerably during the last few years ,partly because of engineers and scientists using new and sophisticated instruments .The spatial and temporal structure of lake hydrodynamic processes can able to control the lake water quality monitoring very much. One of the most important thermo physical properties of lake water is its electrical conductivity (EC) and this maintains almost a linear relationship with total Dissolved solids (TDS) in case of Rudrasagar, a natural lake in western Tripura. Recent studies on Rudrasagar lake suggest that there exists a good correlation between these two parameters and also both of these increase with depth. The objective of this study is to investigate the temporal and spatial variation of EC which may be a good indicator of water quality monitoring and also of environmental monitoring of the lake surrounding. Seasonal variation of these two parameters EC and TDS has also been analyzed here for following the seasonal trend of water quality. Timerelevant information about water quality monitoring and its availability to residents of lake area is very much significant in this regard.
