A total 63 random samples were collected from different sources like stone spout, tap, well, boring, hand pumps jar wards Kageshwori Manohara Municipality, Kathmandu. carried out for 6 months January July, 2019. pH range 6.5-7.2, temperature 5-19 °C, chloride 0-96.56 mg/L, nitrate 0-5.4 mg/L iron 0-1.1 mg/L. physicochemical parameters including pH, temperature, chloride, found lie within WHO guideline value except where 4 (6.34%) 2 1 boring well exceeded guideline. bacteriological analysis revealed presence coliform 35 (55.56%) samples, among which 8 (12.69%) have faecal coliform.
