Good quality water is important for living beings to avoid many health problems. But in the present time availability of good quality water especially groundwater is very scarce. The present study area Guhla block is located in Kaithal district of Haryana state. The geo-coordinates of the study area are latitudes 29.94 N to 30.19 N and 0 0 longitudes 76.19 E to 76.47 E. The study area covers 372.48 sq. km area. Geologically 0 0 alluvium and geomorphologically alluvial plain are present in the study area. The main objective was to assess groundwater quality for drinking purpose in the study area. In the study area nine groundwater samples were collected in 250 ml double capped plastic bottles. Geo-coordinates of sample locations were noted with the help of mobile GPS. Chemical analysis of nine groundwater samples were done using Tamilnadu Water Supply and Drainage (TWAD) Board, Chennai prepared Field Water Testing kit for twelve chemical parameters viz. pH, alkalinity, hardness, chloride, total dissolved solids, fluoride, iron, nitrite, nitrate, ammonia, phosphate and residual chlorine. Results of groundwater samples analysis were compared with BIS drinking water standards (IS 10500:2012) to know groundwater quality for drinking purpose. In the study area pH ranges 7.5 to 9, alkalinity 270 mg/l to 570 mg/l, hardness 130 mg/l to 420 mg/l, chloride 20 mg/l to 110 mg/l, TDS 672 mg/l to 1200 mg/l, fluoride nil to 2 mg/l, iron nil to 2 mg/l, ammonia nil to 1 mg/l, nitrite 0.2 mg/l to 0.5 mg/l, nitrate 45 mg/l to 150 mg/l, phosphate nil in all the nine groundwater samples and residual chlorine nil to 0.2 mg/l. The study is highly useful for planning and monitoring of groundwater quality for drinking purpose in the study area.
