Comparison of two combined sewer overflow (CSO) events of different magnitudes. DOI: https://doi.org/10.1525/elementa.301.t2
| Event | Duration (h) | Volume CSO (MG)a | Mean HBb (CNc 100 ml−1) | Mean sewage (%)d | Loade (HB CN) |
|---|---|---|---|---|---|
| 19 June 2009 | 38.5 | 935.7 | 2.26 × 105 | 0.81 | 1.70 × 1016 |
| 20 June 2011 | 14.0 | 170.5 | 3.97 × 104 | 0.14 | 2.74 × 1015 |
a
Million gallons.
b
Mean HB (human Bacteroides) concentration at estuary station during the CSO event.
c
Copy number.
d
Computed using a geomean of 2.77 × 107 HB 100 ml−1 in untreated sewage.
e
Based on flow measurements from USGS station and 2-h concentrations of human Bacteroides (HB); loads during the CSO event are displayed and loads for full event are shown in Table 3.
