ASSESSMENT OF GROUNDWATER QUALITY FOR DRINKING PURPOSE IN RAI BLOCK, SONIPAT DISTRICT, HARYANA, INDIA

Abstract

Water is important for survival of living beings on the planet Earth. Drinking water quality should be as per drinking water standards to avoid the health effects. Anthropogenic activities have deteriorated the groundwater quality. In urban areas groundwater quality is more or less not suitable for drinking purpose. Shallow water table areas are more prone to water pollution due to anthropogenic activities. Rai block is located in Sonipat district of Haryana. The block covers an area of 280.49 sq.km. In the present study 20 groundwater samples in Rai block were collected in the month of January, 2019. The samples were analyzed using Field Water Testing Kit prepared by Tamil Nadu water Supply and Drainage Board, Chennai for twelve chemical parameters-pH, alkalinity, hardness, chloride, total dissolved solids (TDS), fluoride, iron, nitrate, nitrite, ammonia, phosphate and residual chlorine. Chemical analysis of groundwater samples show that pH 6.5 to 9, alkalinity 100-2700 mg/l, hardness 130920 mg/l, chloride 20 750 mg/l, TDS 828-3350 mg/l, fluoride 1-3 mg/l, iron nil to 5 mg/l, ammonia 0.5 1 mg/l, nitrite 0.2-1.0 mg/l, nitrate 45-100 mg/l, phosphate nil to 2 mg/l and residual chlorine nil to 0.2 mg/l. Groundwater is non-potable at Rasoi-2 (pH 9, alkalinity 860 mg/l, fluoride 2 mg/l, iron 5 mg/l, ammonia 1mg/l, nitrate 100mg/l), Rasoi-1 (alkalinity 2700 mg/l, TDS 3350 mg/l, fluoride 3 mg/l, nitrate 100 mg/l), Jakholi-3 (alkalinity 780 mg/l, nitrate 100 mg/l), Nathupur (alkalinity 850 mg/l, fluoride 3 mg/l, ammonia 1 mg/l), Bahalgarh (Hardness 920 mg/l, TDS 2388 mg/l, fluoride 2 mg/l, ammonia 1mg/l), Jatheri-1 (Hardness 700 mg/l), Liwaspur (Hardness 800 mg/l, TDS 2064 mg/l, ammonia 1 mg/l), Sabauli (fluoride 3 mg/l, nitrate 100 mg/l), Nangal Kalan (fluoride 3 mg/l, ammonia 1 mg/l, nitrate 75 mg/l), Patla-2 (iron 3mg/l, ammonia 1 mg/l), Jakholi-2 (iron 1 mg/l, nitrate 100 mg/l, phosphate 2 mg/l ), Sewli-1(ammonia 1mg/l), Rai-1( ammonia 1 mg/l), Jat Joshi (ammonia 1 mg/l), Jat Joshi-2 (ammonia 1 mg/l). The study is highly useful for monitoring groundwater quality for drinking purpose in the study area.
