Assessing Continuous Contamination Discharge From A Combined Sewer Outfall (Cso) Into A Tidal Wetland Creek: Bacteriological And Heavy Metals Indicators, Timothy Eaton, Gregory D. O'Mullan, Ashaki A. Rouff

Publications and Research

Continuous discharge from a combined sewer overflow (CSO) into a tidal wetland creek in the New York City urban area was analyzed to assess the extent of water quality degradation from fecal bacteria contamination during both dry and wet weather. A combination of fecal indicator bacteria (FIB), total suspended solids, and dissolved metals were used to infer the presence of sewage pollution from the CSO discharge and to constrain the spatial and temporal impact on water quality and dry season creek flows. Upstream of the CSO, creek flow was dominated by groundwater input, and FIB levels were very low or …
