BACTERIOLOGICAL QUALITY OF DRINKING WATER SUPPLIES IN KHULNA CITY, BANGLADESH (Pages : 31 - 34)

The whole concepts adopted for microbiological quality is that no water intended for human consumption shall contain E. coli in 100 ml sample. Our study was aimed to investigate the extent of bacterial contamination among protected and unprotected water sources and potable quality of drinking water was assessed from seven (07) selected areas in Khulna city, Bangladesh. The experiment was conducted during May-June 2007. Water from the mains (pump water) and corresponding residences (households) were tested paralally for the presence of coliform organism. Analysis of bacteriological quality of pump water and household’s water showed that 36.36% pump water and 42.86% of household water were contaminated with faecal-coliform and coliform of non-fecal origin. Our study concludes that 71.43% drinking water sources of Khulna city are unsafe & not potable. We suggest that regular quality control measures to be adopted to ensure safe drinking water.Download
