Abstract: Evaluation of groundwater quality for irrigation is crucial in arid and semiarid regions of the world because of increasing population, urbanization and rapid growth of industries. In order to ascertain the quality of groundwater, water samples were collected from all the villages of Kaithal block. One hundred thirty two water samples were collected and analyzed for pH, electrical conductivity (EC), soluble cations (Ca2+, Mg2+, Na+ and K+) and anions (CO32-, HCO3-, Cl-, SO42- and NO3-) by using standard procedures. The values of sodium adsorption ratio (SAR) and residual sodium carbonate (RSC) of water samples were computed. The pH, EC, SAR and RSC in groundwater ranged from 7.25-9.25, 0.47-6.06 (dSm-1), 3.69- 28.59 (mmol l-1)1/2, 0-5.70 (me l-1), respectively. The concentration of cations viz., Ca2+, Mg2+, Na+ and K+ varied from 0.40-3.00, 1.10-11.00, 3.20-53.10, 0.06-1.00, me l-1 with mean values of 1.16, 3.59, 16.15, and 0.17 me l-1, respectively. Likewise, the concentration of anions viz., CO32-, HCO3-, Cl-, SO42- and NO3- varied from 0-2.90, 1.00- 8.10, 2.00-28.80,0.28-30.08 and 0-0.90 me l-1 with average values of 1.43, 4.66, 7.32, 7.20 and 0.46 me l-1, respectively. According to AICRP classification, 31.1, 26.5, 8.3, 8.3, 9.9 and 15.9% were of good, marginally saline, high SAR saline, marginally alkali, alkali and highly alkali, respectively. Spatial variability maps of EC, pH, SAR, RSC and water quality of groundwater used for irrigation in the block were also generated. By and large, the analysis of various parameters indicated that quality of groundwater is not safe for irrigation purposes.
