All test samples, before and after treatment, were collected in nonreactive, precleaned, and sterilized (Standard Methods 9050A) borosilicate glass or plastic bottles. Samples of combined sewage were collected at the water treatment facility in Perth Amboy, New Jersey. The samples were allowed to stand for two hours at room temperature and then decanted using a siphon hose. The decanted samples were well mixed, analyzed, and stored at 4◦C. The settled, decanted, and mixed CSO sample used for this study contained 290 mg/L of dissolved organic carbon (DOC), 28 mg/L of total suspended solids (TSS), and 2.6 to 7.5 × 106 colony forming units (CFU)/100 mL of
E. coli.
