Summary:The estimation of groundwater quality for individual aquifers in a multi-aquifer system is beset with many problems. An attempt is made to quantify the hydrogeochemical parameters using Self Potential logs for different aquifers in a major coastal sedimentary basin. This involves establishing a relationship between R w and R we for the system and then using analytical scatter diagrams between dissolved solids and various individual cations and anions. The results obtained through these trend analyses and scatter plots for a multi-layered coastal system are compared with the chemical analyses of water samples and are found to be in close agreement. This approach would reduce drill-stem tests which are costly and risky and also minimise uncertainties in the assessment of quality variations for individual zones in multi-aquifer systems.
