We conducted field surveys in Tokyo Bay, Japan, to monitor the influences of storm water and combined sewage overflow. Considerable increases in both fecal markers and detritus particulate organic carbon were observed in surface waters concomitant with low salinity and high turbidity (flood survey) compared with the control survey conducted under clear weather. Based on the ratio of coprostanol concentrations in freshwater status (salinity 0) during the flood survey to those during the control survey, the extent of the increase in the pollution concentrations into Tokyo Bay via both storm water and combined sewage overflow was approximately double.
