A baseline study involving analyses of surface and bore well water samples from the vaippar river basin was carried out in order to assess their suitability for drinking domestic and agricultural purposes. The data obtained are used to determine important quality parameters and ratio’s. High TDS found in groundwater of gneissic and granitic aquifers. Based on the salinity and sodium hazard for irrigation quality, C2S1, C3S1, C3S2 and C4S1 are quality classes found not suitable for even salt tolerant crops in the study area. The quality parameters of the groundwater samples has been matched with ISI standards (1991).
