Physicochemical properties of water pH, EC and TDS has relationship with total coliform count, total bacterial count and E. coli in terms of seasonal variations. It had been observed the highest values of TCC, TBC and fecal coliform was significantly higher in July as compare to April and December, Because the monsoon floods in river Kabul carries more pollutants from nearby fields. All these factors contribute in deteriorating the drinking water quality of study area. pH has positive effect on the growth and persistence of E.coli. Similarly, EC and TDS have influence on transport and fate of these faecal coliform. E. coli is extensively used as indicator organism for faecal contamination of water. The disease risk due to waterborne pathogens is directly related to the concentration of waterborne pathogens in surface and drinking water. This pathogen concentration is influenced by extreme precipitation and floods. More pathogens enter the surface water when floods flush ineffectively treated sewage and manure into surface waters and increase concentrations. As future extreme precipitation and flood frequencies are expected to increase due to climate change, it is essential to better understand the relationship between extreme precipitation, flooding and the concentration of waterborne pathogens in the surface waters. Water managers can then prepare for possible increased health risk in these situations.
