The present study deals with the comparative quality of drinking waters of different sources at Chapra (Saran) – Bihar, which is located on the South bank of river Sarayu at 86002’N Latitude and 24-15 E Longitude. The municipal supply water gets severely contaminated by waste water through rusted and damaged pipelines and the groundwater through seepage from septic tanks, drains and deep sewerage system. The contaminants from these sources have deteriorated the quality of drinking water leading to spread of various water-born diseases due to increase in the value of turbidity, nitrate – nitrogen, total bacterial density and MPN coliform. The higher concentration of nitrate chloride and the presence of E. coli, Staphylococcus aureus, Proteus vulgaris, Pseudomonas aeruginosa and Salmonella typhi indicated the faecal contamination.
