Description |
To characterize the groundwater quality and study their impact on physico-chemical properties of soil, 255 water and 28 soil profile samples from two sites for each category of water were collected from villages of Rewari and Bawal blocks of district Rewari.These samples were analysed and classified. According to AICRP (1989) classification, 39, 18, 10, 17, 3, 9 and 4 % waters in Rewari block and 34, 26,10, 10, 5, 13 and 2 % waters in Bawal block were found to be in good, marginal saline, saline ,high SAR saline, marginal alkali, alkali and highly alkali, respectively. Whereas according to Manchanda (1976) classification, 41,19,10,13 and 17 % waters of Rewari block and 36,28,10,16 and 10 % waters of Bawal block’s were classified under good, marginal, saline, sodic and saline sodic categories, respectively. The analysis of water samples of underground irrigation waters showed that pH, EC, RSC and SAR varied from 7.45 to 9.11, 0.28 to13.38 dS m -1 , nil to 9.65 me l -1 , 1.14to 19.45 (mmol -1 ) 1/2 in Rewari block and from 7.19 to 9.45, 0.35 to 11.36 dS m -1 , nil to 5.96 me l -1 , 2.51 to 19.41 (mmol -1 ) 1/2 in Bawal block. The sodium was dominant cation followed by magnesium, calcium and potassium in ground waters of both the blocks. Likewise, in case of anions, chloride was the dominant anion followed by bicarbonate, sulphate, carbonate, nitrate and fluoride. The analysis of soil saturation extract indicated that the highest pH of the soil in Rewari block was in village Chandawas (9.10) and lowest in village Balawas (7.29). Whereas in Bawal block, the highest pH of the soil saturation extract was observed in village Berwal (8.99) and lowest in village Patuhera (7.30) in the soil profile. The highest ECe in Rewari block was observed in village Chandawas (6.29 dSm −1 ) and lowest was found in village Janti (1.30 dSm −1 ).The highest ECe in Bawal block was observed in village Saban ( 10.82 dSm −1 ) and lowest was found in village Bakapur (1.50 dSm −1 ). The use of poor quality water resulted in salt accumulation throughout the soil profiles. Highest electrical conductivity was observed in surface layers of the soil which gradually decreased with depth irrespective of texture and quality of irrigation water.The highest CEC of the soil in Rewari block was observed in village Budana (5.26 cmol (+) kg −1 ) and lowest was found in village Garhi Alawalpur (3.96 cmol (+) kg −1 ) whereas in Bawal block, highest CEC was observed in village Khera Murar (6.92 cmol (+) kg −1 )and lowest was found in village Suthana (3.69cmol (+) kg −1 ).The highest ESP of the soil in Rewari block was found in village Surajpura (17.22) and lowest was found in village Balawas (3.25) whereas in Bawal block, the highest ESP was observed in village Pithanwas ( 21.20) and lowest was found in village Bakapur (4.56).The mean cationic composition of soil extract in soil profile in both Rewari and Bawal blocks, was of the order Na + >Ca 2+ >Mg 2+ K + likewise, in most of the samples the mean anionic composition of soil extact was of order Cl ->SO 4 2->HCO 3 ->CO 3 2-. A significant positive correlation of 0.897 and 0.977 between ECiw and ECe and of 0.619 and 0.816 between SARiw and SARe was also found in Rewari and Bawal blocks, respectively. The groundwater quality maps of Rewari and Bawal blocks constructed indicated that maximum area was falling under poor quality waters with more area under salinity hazard ( marginally saline,saline and saline) as compared to area under sodicity hazard (marginally alkali, alkali and highly alkali) in both the blocks. |
