The main objective of this model is to combine the results using DRASTIC algorithms and Geographical Information System (GIS), and to depict it as an effective method for groundwater pollution risk assessment. DRASTIC Model requires seven environmental parameters such as depth to water-level, net recharge, aquifer media, soil media, topography, impact of vadose zone and hydraulic conductivity of the area. All the parameters were integrated in the drastic model using GIS spatial analysis tools and techniques. The Groundwater Vulnerability Index of the active notes within the study is computed using GIS modeling methods. The Vulnerability index of the groundwater in this region ranges from < 70 to >100. The outcome shows that, when the net recharge is high, the vulnerability is also found to be high. The GIS application of the DRASTIC model is found to be a suitable method for analyzing the groundwater vulnerability in Mysore city.

Assessment of ground water quality status in Mysore city by using water quality index (WQI) method was carried out. From the sampling locations spread throughout city, 53 groundwater samples were collected both in pre- and post-monsoon seasons. WQI has been determined by subjecting the samples to comprehensive physicochemical analysis. For calculating the WQI, the following 13 parameters have been considered: pH, EC, TH, TDS, Ca2+, Mg2+, Na+, K+, CO3 2-, HCO3 -, SO4 2-, Cl- and NO3 -. The WQI for the groundwater samples ranges from 42.61 to 109.51 and from 39.82 to 166.19 for PRM and POM seasons respectively. The results of some of the water samples show values over the permissible limits of WHO and BIS standards for drinking waters for parameters such as calcium and magnesium cations, nitrate and sulphate anions, and also in the global parameters: salinity and TDS. The elevated value of WQI has been found to be mainly from the h...

The results of some of the water samples show values over the permissible limits of WHO and BIS standards for drinking waters for parameters such as calcium and magnesium cations, nitrate and sulphate anions, and also in the global parameters: salinity and TDS. The elevated value of WQI has been found to be mainly from the higher values of nitrate and hardness in the groundwater. The analysis reveals that the groundwater of the area needs some degree of treatment before consumption.
