Abstract:
An investigation was undertaken to study underground water quality of Saurashtra region of Gujarat state. Total 750 underground water samples were collected from wells or bore wells of all 75 talukas of ten districts of Saurashtra region in Gujarat state during the year of 2021. The water samples were collected by using GPS and analyzed for various heavy metals like Pb, Cd, Cu and Zn. In Saurashtra region the proportions of Pb, Cd, Cu, and Zn ranged from 0.005 to 0.189, 0.001 to 0.016, 0.008 to 0.105 and 0.003 to 0.065 mg/l with a mean value of 0.043 mg/l, 0.005 mg/l, 0.026 mg/l and 0.017 mg/l, respectively. The analytical results showed that the Pb, Cu and Zn concentration were within the permissible limits of 5 mg/l, 0.2 mg/l and 2 mg/l, respectively except Cd. The data showed that 2 per cent of the samples contained Cd concentration of greater than permissible level (>0.01 mg/l) so they categorised as unsafe. Amreli district was found to have the highest mean Cd value (0.006 mg/l) in underground water samples.
