ASSESSMENT OF GROUNDWATER QUALITY FOR DRINKING PURPOSE IN BARWALA TOWN AND ITS SURROUNDINGS, PANCHKULA DISTRICT, HARYANA, INDIA

Water is important for drinking, agriculture and industrial purposes. Water quality plays vital role in its utilization for different purposes. Water quality for drinking purpose should be as per BIS drinking water standards (IS 10500:2012). Barwala town in Panchkula district, Haryana, India has been selected in the present study for groundwater quality assessment for drinking purpose. In the study area six groundwater samples were collected in the month of June 2019 in plastic 250 ml bottles. Geo-coordinates of the sample locations noted with mobile GPS. Groundwater samples were analysed using Field Water Testing Kit prepared by Tamilnadu Water Supply and Drainage Board (TWAD) Chennai for ten chemical parameters-pH, hardness, chloride, fluoride, iron, ammonia, nitrite, nitrate, phosphate and residual chlorine. In the study area pH ranges from7 to 8, hardness ranges from 150 mg/l to 400 mg/l, chloride ranges from 100 mg/l to 150 mg/l, fluoride ranges from 0.5 mg/l to 2 mg/l, iron ranges from 0 mg/l to 5.0 mg/l,ammonia ranges from 0.5 mg/l to 5.0 mg/l, nitrite ranges from 0.2 mg/l to 1 mg/l, nitrate ranges from 45 mg/l to 150 mg/l,phosphate ranges from 0.5 mg/l to 1.0 mg/l and residual chlorine ranges from 0 mg/l to 0.5 mg/l. In the study area groundwater quality is non-potable in five groundwater samples and potable in one groundwater sample. The study is highly useful for monitoring of groundwater quality for drinking purpose in the study area.
