Assessment of Groundwater Quality for Drinking Purpose in Charkhi Dadri Block in Charkhi Dadri District, Haryana

Abstract

Water is important for living organisms on the Earth. Present development activities have put pressure on water resources. Groundwater is under more stress because of high exploitation for drinking, irrigation and industrial purposes. In the arid to semi-arid climatic zones groundwater is very important for sustaining day to day activities and agriculture and industrial purposes. The present study area Charkhi Dadri block in Charkhi Dadri district, Haryana was selected to 0 0 study groundwater quality for drinking purpose. The geo-coordinates of the study area are latitudes 28.49 N to 28.70 N 0 0 and longitudes 76.05 E to 76.47 E and covers an area of 396.57 sq. km. In the study area ten groundwater samples were collected in double capped 250 ml plastic bottles. Geo-coordinates of the sample locations were noted using mobile GPS. Chemical analysis of all the ten groundwater samples were done using Tamilnadu Water Supply and Drainage Board (TWAD), Chennai prepared Field Water Testing kit for twelve chemical parameters viz. pH, alkalinity, hardness, chloride, total dissolved solids (TDS), fluoride, iron, nitrite, nitrate, ammonia, phosphate and residual chlorine. Chemical analysis results were entered in excel software and prepared bar graphs. Result of groundwater samples analysis were compared with BIS (IS 10500:2012) drinking water standard to know the suitability of groundwater for drinking purpose. The study shows that pH ranges 7 to 8, alkalinity 200 mg/l to 450 mg/l, hardness 130 mg/l to 800 mg/l, chloride 40 mg/l to 1200 mg/l, TDS 552 mg/l to 2820 mg/l, fluoride 0.5 mg/l to 5 mg/l, iron nil to 0.3 mg/l, ammonia nil to 1 mg/l, nitrite 0.2 mg/l to 1 mg/l, nitrate 45 mg/l to 100 mg/l, phosphate nil in all the ten groundwater samples and residual chlorine nil to 0.2 mg/l. The study is highly useful for planning and monitoring of groundwater for drinking purpose in the study area.
