Assessment of drinking water quality was carried out at Bangalore city and samples were collected from different parts of Bangalore west zone ward wise namely Rajarajeshwari nagar, Vijayanagar, Rajajinagar, Nagarbhavi. The Results showed that 26% of the samples exceeded with permissible limits for BOD. (Vijaynagar (5.6mg/L), Agrahara Dasarahalli, Manjunatha Nagar (5.0mg/L), Mahalakshmi Layout (6.8mg/L), Jyoti Nagar (4.8mg/L), Kamashipalya (12.0mg/L), Mysore Road (3.0mg/L)). Highest variation of COD values recorded in the study. About 60% of the total samples showed total dissolved solids levels above the desirable limit of 500mg/L. About 60% of the samples showed above desirable limit of drinking water standard values for TDS. This may be due to different topography, water distribution system and impact of domestic water pollution which imparts in water quality. Drinking water contaminated by human or animal waste and also due to breakage of pipelines.
Key words: Drinking water quality, water distribution system, biological oxygen demand, chemical oxygen demand, total dissolved solids
