title: Study of ground water quality for irrigation in some villages of Surat District, Gujarat (India).
abstract: 40 ground water samples of 10 villages in Surat district, Gujarat (India) were analyzed for their suitability for irrigation purpose. The mean values of 4 samples taken from each village have been reported in the present study. Ground water of the study area was classified according to sodium adsorption ratio (SAR), percentage sodium (PS), residual sodium carbonate (RSC), Kelley's ratio and electrical conductivity. The value of sodium adsorption ratio indicated that majority of samples (9 out of 10) fall in low sodium hazard category. As per classification made by Wilcox (1948), on the basis of percentage sodium and electrical conductivity, only 1 sample (Vesu) not found suitable for irrigation purpose while only 1 sample (Gaviyar) found in good category. The remaining 8 samples were in good to permissible and permissible to doubtful category. Ground water was also classified according to the classification of United States Salinity Laboratory based on sodium and salinity hazard.
