The current study was conducted to investigate the drinking water quality of flood affected areas of district, Charasadda. A total of 156 samples were collected; 73 house-wells, 35 motor pump and 48 hand pump in sterile 100 ml of flask, representing 20 affected villages. Samples were serially diluted into 10 ml, 1ml and 0.1 ml. Most probable number (MPN) technique was used for the counting of total coliform, fecal coliform and Escherichia coli. The results showed an exceeding value of MPN index / ml and range of 95% probability in House Wells (≥ 60 MPN), Hand Pump (> 41MPN) and Motor Pump (>20 MPN). The biochemical investigations showed that E.coli contributed 62%, Salmonella 21% and Shigella were 16% in total samples. Presence of large counts of bacteria bacillary dysentery, Typhoid fever and Para typhoid fever were common among flood affecters.
