The present study highlights techniques to identify suitability of water for drinking and irrigation uses. Twenty water samples from Dang district of Gujarat state were collected in pre-monsoon (PRM) and post-monsoon (POM) seasons and analyzed for different physico-chemical properties. The Water Quality Index varied from 37.83 to 121.68 in PRM season and from 40.09 to 152.83 in POM season. Surface water quality in the Dang district was good for drinking in 58.43 % and 64.43 % area in PRM and POM season, respectively. The US Salinity diagram showed that most of the water samples belong to the categories C2S1 and C2S2 (suitable class for irrigation) in both the seasons. Some samples falling in the category C3S2 are also acceptable for irrigation use in both the seasons.
