We assessed groundwater quality for irrigation purpose in intensively wheat cultivated semi-arid regions of Haryana during 2008. Eight to ten water samples from each representing village of Bawani Khera and Bhiwani blocks of Bhiwani district of Haryana were collected from running tube-wells and analyzed for pH, electrical conductivity (EC), soluble cations (Ca+2, Mg+2, Na+ and K+) and anions (CO32, HCO3-, SO4-2, Cl", NO 3- and F-) as well as categorized on the basis of water quality classification of Manchanda (1976) and All India Co-ordinated Research Project (1989). Results revealed that pH, EC, SAR and RSC in ground waters of Bawani Khera block varied from 7.56-9.23,0.26-18.49 (d/Sm), 0.11-39.82 (mmol/l)1/2 and nil-6.60 (me/1), respectively. Likewise, corresponding values of groundwater samples for Bhiwani block varied from 7.43-9.67, 0.25-18.26 (dS/m), 0.32-65.41 (mmol/1)1/2 and nil-7.20 (me/1), respectively. Cations were in the order Na+>Mg+2> Ca+2>K+, while anions were C1->SO 4-2>HCO3->CO3 -2 in both the blocks. As per Manchanda (1976) classification in Bawani Khera block 19.0, 19.0, 21.0, 6.0 and 35% water samples were found to be good, marginal, saline, sodic and saline-sodic, respectively. Likewise according to AICRP (1989) criteria 19.0% water samples were found in good category, 19.0% marginally saline and 21.0% saline. Of the remaining 41.0% waters, 6.0% were highly alkali and 35.0% were high SAR saline waters. Similarly, in Bhiwani block 20.0% water samples were good, whereas 17.0, 20.0, 5.0 and 38.0% waters were categorized as marginal, saline, sodic and saline-sodic as per Manchanda (1976) classification. As per AICRP (1989) classification, 19.0% water samples were found under good category, 17.0% marginally saline, 21.0% saline, 2.0% marginally alkali, 4.0% highly alkali, and 37.0% water samples were classified as high SAR saline waters. Spatial distribution of ground water quality did not follow any definite pattern in any direction but it showed that good quality waters frequency was more in grid blocks where canal supply was more assured and vice versa.
