| Outline of Final Research Achievements |
The purposes of this study are i) to quantify the pollutant loads derived from combined sewer overflow (CSO) and ii) to evaluate its impact on water quality in Odaiba surrounding waters. The research outcomes can contribute to control of fecal contamination in waterfront areas. We collected wet weather sewage and coastal water samples after rainfall event. Then we investigated presence and fate of pathogenic microorganisms, including viruses. We performed water quality predictions by 3-dimensional coastal water quality model, giving CSO pollutant load conditions. Then we assessed the fecal contamination and discussed its control in Odaiba surrounding waters.
