Assessment of microbiological and physico-chemical characterıstics of water samples in households of Bangalore city, Karnataka, India

Access to safe drinking water is one of the basic human rights and is essential to human health. The present study investigated the concentration of pathogenic microbial flora and health risk in drinking water samples in households of Bangalore city, Karnataka, India. The samples were analysed for m...
