Abstract
The present work was designed to analyze the quality of drinking water of new campus Punjab University, Lahore. This site was further divided into three areas such as residential/colony area, hostels and departmental areas for sampling purpose. Bacteriological quality of drinking water was assessed through microbiological techniques and biochemical testing by MICROBACT TM GNB 12A/B/E, 24E Identification kit. It was noticed that drinking water was fully contaminated with enumerable species of Enterobacteriaceae. Some of which are faecal coliform i.e. Enterobacter. cloacae, Enterobacter. Sakazakii, Hafnia. alvei, Citrobacter sp10 A, Citrobacter sp10 B ,Enterobacter agglomerans A, Enterobacter agglomerans B, Enterobacter agglomerans C and non faecal human pathogenic bacteria i.e. Enteric Gp59 ,Escherchia coli-inactive, Yersinia ruckeri, Yersinia. pestis, Serratia rubidaea, Serratia. liquefaciens, Serratia. plymuthica , Serratia. marcescens biogp1 A, Serratia. marcescens biogp1B, , Acinetobacter haemolyticus, and Acinetobacter. baumannii A, Acinetobacter. baumannii B. All of these are opportunistic human pathogens. The presence of E.coli ensure poor quality of water because it is considered to be a universal indicator of contamination in water and water resources.
