This is a residential area and was filled with flood water for more than 3 weeks. The highest number of coliforms was found at Point A, which is considered as a dense traffic area. The number of coliforms at this point was found to be higher than the number at Point D, which is highly populated. Although water level at Point A begins to reduce, water quality at this station is hardly to be improved by dilution. Besides Point A, coliform numbers were found to be less than 10^2 CFU/mL. In addition, there was no obvious correlation between DO concentrations and coliform numbers.
