摘要: Abstract A set of fecal indicator bacteria and alternative markers were tested for their use to identify priority sectors two urban watersheds in the Greater Montreal region with unintended household sewage connections storm drainage systems. Analyses performed thermotolerant (fecal) coliforms (FC), Escherichia coli, human-specific Bacteroidales (HF183) mitochondrial DNA (Hmt) markers, carbamazepine (CBZ), caffeine (CAF), theophylline (THEO) acetaminophen (ACE). high incidence human contamination was observed, illustrating need a method appropriately prioritize rehabilitation sewer cross-connections. Concentrations not significantly different between residential industrial/commercial/institutional (ICI) sectors. However, median E. coli concentrations higher as compared ICI (p 0.61, p 0.59, p
