Geochemical analysis of groundwater samples in the vicinity of lakes and drainage network

Geochemical analysis of ground water samples in the vicinity of lakes and drainage network were carried out in and around a selected set of polluted lakes in the city of Hyderabad, India for possible restoration of the polluted lakes from the state of eutrophication. The results reveal, in general the concentration of TDS and major ions higher in the down stream areas due to shallow water table as well as seepage from lakes and nalas. Further, the concentration of trace elements in ground water was found to be within the permissible limits. The Piper and Wilcox diagrams indicate that the ground water in the study area has low sodium and high salinity hazard.
