Abstract

Microbial contamination of ground water sources is a common problem in all the big cities, which endangers health and impairs quality of living . To assess this, 39 water samples were collected from highly populated 13 union councils from the urban area of district Mardan. Faecal coliform and Escherichia coli were investigated both qualitatively and quantitatively. Qualitative study showed that faecal coliform was found in 90% samples and E. coli in 56% samples. Quantitatively, faecal coliform most probable number (MPN) was ranging from 1601 to 2400 for about 28% samples, followed by 551 to 1600 and 201 to 550 for 20% samples each, 40 to 200 for 18% samples and less than 40 for about 13% samples. The major cause of the bacteriological contamination was found to be the extent of susceptibility of the water sources to intrusions from the nearest contamination source.
