The range of variation in different parameters was pH 7.2-9.04, DO 4.52-6.93 mg, EC 1.12-1.8 mmho, BOD 1.93-21.63 mg/litre, COD 13.77-56.11 mg/litre, alkalinity 208-366 mg/litre, hardness 308-544 mg/litre, sodium 0.05-674 mg/litre, potassium 0.04-1.40 mg/litre, magnesium 31.8-72.05 mg/litre, sulfate 0.03-40.23 mg/litre, phosphate 0.02-0.72 mg/litre and moisture content 8.69-18.69% during winter and monsoon seasons. The range of almost all the parameters was found to be highest in Buria nala except DO and moisture content. Groundwater in Faridabad was dark black in colour, alkaline and unpleasant in taste. All the heavy metals were within the prescribed range except iron which was between 0.15-18.59 mg/litre. Based on the concentration of different parameters studied, the selected site may be arranged in the order of Buria nala > Yamuna river > bus stand > railway station > residential colony. Results revealed that groundwater of Faridabad is highly polluted as the level of all the tested parameters was higher than the admissible limits and unfit for drinking. 收起
