Abstract: Short duration intensive inflows of combined sewer overflows (CSO) to marine tidal basins create stratified water quality for limited periods of time. Accurate assessment of water quality in the tidal basins and in major receiving water bodies can only be developed through an understanding of the stratification developed between the low density combined sewer overflows and the higher density marine water. This paper summarizes analyses conducted to assess CSO pollutant loadings and water quality impacts in a tidal basin in New York City.
