GROUNDWATER QUALITY ASSESSMENT FOR DRINKING PURPOSE IN BADHRA BLOCK, CHARKHI DADRI DISTRICT, HARYANA, INDIA

Water is important for survival of living beings and non-living developmental activities. In the present developmental scenario requirement of water is increasing very fast. In arid to semi-arid regions groundwater is very important for fulfilling the need of people. Badhra block is falling in Charkhi Dadri district of Haryana state, India. The climate of the block is semi-arid. Groundwater is the main source for drinking and irrigation purpose. In the study area ten groundwater samples were collected in the month of January, 2019. Groundwater samples were analyzed using field water testing kit prepared by Tamilnadu Water Supply and Drainage Board, Chennai for twelve chemical parameters-pH, alkalinity, hardness, chloride, total dissolved solids, fluoride, iron, nitrite, nitrate, ammonia, phosphate and residual chlorine. In the groundwater samples pH varies from 7 to 7.5, alkalinity 250-450 mg/l,hardness 70 - 580 mg/l,chloride 60-600 mg/l, total dissolved solids (TDS) 564-1704 mg/l, fluoride 0.5-3 mg/l, iron nil in all groundwater samples, ammonia nil to 1 mg/l, nitrite 0.2- 0.5 mg/l, nitrate 45-75mg/l, phosphate nil to 0.5 mg/l, residual chlorine nil in all ten groundwater samples. Groundwater is potable in one sample taken at Dalawas and non-potable in nine groundwater samples taken at Lad (fluoride 2 mg/l, ammonia 1mg/l, nitrate 75mg/l), Badhara (fluoride 3mg/l), Kari (nitrate 75mg/l), Sisrli (nitrate 75mg/l), Dandma (nitrate 75mg/l), Jeoli (nitrite 75 mg/l), Mandi (nitrate 75 mg/l), Rahrodi (nitrate 75mg/l), Dohka (nitrate 75mg/l). The study is highly useful for monitoring of groundwater quality for drinking purpose.
