GROUNDWATER QUALITY ASSESSMENT FOR DRINKING PURPOSE IN LADWA BLOCK OF KURUSHETRA DISTRICT, HARYANA

Water is used for drinking, irrigation and industrial purposes. In the present context of developmental activities requirement of water has increased many folds which resulted in declining of per capita water availability. Further in agriculture dominant areas groundwater is excessively used for irrigation which also resulted in declining of water table and quality deterioration. The study area Ladwa block is located in Kurukshetra district 0 0 0 0 of Haryana between the geo-coordinates latitudes 29.95 N to 30.07 N and longitudes 76.97 E to 77.12 E and covers an area of 130.56 sq. km. Geologically alluvium and geomorphologically alluvial plain is present. The main objective was to study 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 (IS 10500:2012) drinking water standards to know the suitability of groundwater for drinking purpose. The study shows that in the study area pH ranges 6.5 to 8, alkalinity 220 mg/l to 380 mg/l, hardness 50 mg/l to 360 mg/l, chloride 30 mg/l to 300 mg/l, total dissolved solids 600 mg/l to 960 mg/l, fluoride nil to 2 mg/l, iron nil to 0.3 mg/l, ammonia nil to 1 mg/l, nitrite 0.2 mg/l to 0.5 mg/l, nitrate 45 mg/l to 100 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.
