Due to non availability of surface water everywhere people rely on groundwater because of availability. In arid to semi-arid regions of the world groundwater is the main source for drinking, iriigration and industrial utilization. In the present study groundwater quality in Hansi-I block has been studied for srinking purpose. In this study, 18 groundwter samples were collected from different locations in the study area. Groundwater samples were analysed for 12 chemical parameters- pH, TDS, Cl, Zn, K, HCO3, CO3, Ca, Mg, Fe, TH, and Mn. BIS 10500:2012 drinking water standards were used for assessment of suitability of groundwater for drinking purpose. In the study area pH ranges 6.9 to 8.3 and desirable at all the groundwater samples.TDS ranges 118 mg/l to 2640 mg/l. TDS is desirable in groundwater samples -Dhnderi School (214 mg/l), Daple (118 mg/l), Sainipura (171 mg/l), Bhidfarm (450 mg/l), Sisai (270 mg/l), bhatla (308 mg/l), Chanak (175 mg/l), Masoodpur (149 mg/l), Dhata (209 mg/l), Sindhar (146 mg/l), Rajli (268 mg/l), Sulakhni (153 mg/l), permissibe in Dhani Qutub (1165 mg/l), Lalpura (1360 mg/l), Majood Temple (1525 mg/l), Ghiraye (1075 mg/l) and non-potable in Civil Hospital (2640 mg/l), Khanpur (2295 mg/l).Manganese ranges 0.02 mg/l to 0.15mg/l and desirable in all groundwater samples. In the study area zinc ranges 4.96 mg/l to 64.82 mg/l. In the study area zinc is non-potable in groundwater samples at Dhnderi School (64.82 mg/l), Daple (62.43mg/l), Dhani Qutub (60.71 mg/l), Civil Hospital (58.23 mg/l), Lalpura (57.09 mg/l), Sainipura (55.62 mg/l), Bhidfarm (53.67 mg/l), Sisai (49.53 mg/l), Bhatla (45.70 mg/l), Chanak (38.94 mg/l), Majood Temple (35.49 mg/l), Masoodpur (29.27 mg/l), Dhata (24.68 mg/l), Khanpur (20.68 mg/l), Sindhar (15.81 mg/l), permissible in Rajli (11.74 mg/l), Ghiraye (7.84 mg/l) and desirable in Sulakhni (4.96 mg/l) groundwater sample. Iron ranges 0.07 mg/l to 0.92 mg/l. Iron is desirable in groundwater samples in Masoodpur (0.29 mg/l), Dhata (0.20 mg/l), Khanpur (0.14 mg/l), Sindhar (0.20 mg/l), Rajli (0.20 mg/l), Ghiraye (0.07 mg/l), Sulakhni (0.07 mg/l) and non-poyable in groundwater samples in Dhnderi School (0.92 mg/l), Daple (0.89 mg/l), Dhani Qutub (0.71 mg/l), Civil Hospital (0.77 mg/l), Lalpura (0.72 mg/l), Sainipura (0.72 mg/l), Bhidfarm (0.64 mg/l), Sisai (0.71 mg/l), Bhatla (0.53 mg/l), Chanak (0.33 mg/l) and Majood Temple (0.36 mg/l). In the study area chloride ranges 2.7 mg/l to 38.2 mg/l and desirable in all the groundwater samples. Hardness ranges 2.8 mg/l to 32.2 mg/l and desirable in all the groundwater samples. In the study area potassium ranges 2.9 to 65 mg/l and desirable in all groundwater samples except Civil Hospital (18.4 mg/l), Lalpura (14.6 mg/l), Majood Temple (65 mg/l), Khanpur (19.3 mg/l), Sulakhni (14.1 mg/l) groundwater samples in which potassium is non-potable. In the study area bicarbonate ranges 0.2 mg/l to 0.5 mg/l and desirable in all the groundwater samples. In the study area carbonate ranges nil to 0.1 mg/l and desirable in all the groundwater samples. In the study area calcium ranges 1.87 mg/l to 21.47 mg/l and desirable in all the groundwater samples. In the study area magnesium ranges 0.93 mg/l to 10.73 mg/l. and desirable in all the groundwater samples. The study is highly useful for planning of groundwater quality for drining purpose in the study area.Englishhttps://journal.stenvironment.org/abstract?id=246References16191. Adhikary, P.
