Study of Ground Water Quality for Irrigation in Near Industrial Area of Bhilwara, Rajasthan (India)

Abstract

47 Ground water samples of 40 villages close to industrial area
of Bhilwara town were analyzed for their suitability for irrigation
purpose. 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 higher value of electrical conductivity, percentage
sodium and Kelley's ratio in some villages indicates the contamination
of ground water by industrial effluent resulting in the unsuitability
of ground water for irrigation purposes. The value of sodium
adsorption ratio indicates that majority of samples falls in low
sodium hazard category. As per classification made by Wilcox
(1948), on the basis of percentage sodium and electrical conductivity
12 samples are not suitable for irrigation purpose while only 3
samples fall in excellent to good category. The remaining 10 samples
fall in good to permissible, 13 samples fall in permissible to
doubtful and 9 samples fall in doubtful to unsuitable category.
Ground water was also classified according to the classification of
United States Salinity Laboratory based on sodium and salinity
hazard.
