STUDY OF GROUNDWATER QUALITY FOR DRINKING PURPOSE IN KHARKHODA BLOCK OF SONIPAT DISTRICT, HARYANA

Groundwater is important because of its drinking, agriculture and industrial uses. Present developmental activities have put pressure on this precious natural resource. In urban areas its quality is deteriorated due to anthropogic pollution like sewerage and industrial waste water mixing with groundwater. The present study area Kharkhoda block is located in Sonipat district, Haryana. The geo-coordinates of the study area are latitudes 28.79 N to 29.01 N and longitudes 76.77 E to 77.02 E and covers an area of 302.03 sq. km. The main objective 0 0 0 0 was to assess groundwater quality for drinking purpose in the study area. Geologically alluvium and geomorphologically alluvial plain are present in the area. In the study area fourteen 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 fourteen 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 (TDS), fluoride, iron, nitrite, nitrate, ammonia, phosphate and residual chlorine. Chemical analysis results were entered in excel software and preaped bar graphs for each chemical parameter for all the fourteen sample locations. Results of groundwater samples analysis were compared with BIS (IS 10500:2012) drinking water standards to know groundwater quality for drinking purpose. In the study area pH ranges 6.5 to 8, alkalinity ranges 180 mg/l to 830 mg/l, hardness ranges 50 mg/l to 1400 mg/l, chloride ranges 20 mg/l to 2800 mg/l, TDS ranges 588 mg/l to 4752 mg/l, fluoride ranges 1 mg/l to 5 mg/l, iron ranges nil to 10 mg/l, ammonia ranges 0.5 mg/l to 1 mg/l, nitrite ranges 0.5 mg/l to 2 mg/l, nitrate ranges 45 mg/l to 100 mg/l, phosphate ranges nil to 1 mg/l, residual chlorine ranges nil to 3 mg/l.This study is highly useful for planning and monitoring of groundwater for drinking purpose in the study area.
