The effect of watertable fluctuations on groundwater salinity is observed for three well- waters near Visakhapatnam, India. The electrical relativity water sample in the well is taken to represent the salinity of water. A correlation between the electrical sensitivities of groundwater samples and the corresponding water table positions over a period of fifteen months is brought out. A peculiar in-phase relation between the water level hydrograph and the salinity curve is recorded, the
