Microbial source tracking studies at beaches and watersheds in the City of Toronto.

Microbial source tracking (MST) studies were conducted to   investigate sources of fecal pollution contaminating Toronto beaches   from Marie Curtis Beach east to Rouge Beach along the Lake Ontario   coastline.  Initially, a large E. coli library was developed to   apply antimicrobial resistance profiling and rep-PCR DNA   fingerprinting techniques in a library-dependent microbial source   tracking approach.  In later years, the HF183 Bacteroidales DNA   marker was applied in a more library-independent MST approach.    Multiple MST methods and other lines of evidence were able to   indicate the prominence of bird fecal contamination at some beaches,   while other beaches near river mouths tended to have more frequent   impacts from municipal wastewater.  Similarly, certain tributaries   of the Humber River and Don River (including stormwater outfalls)   watersheds were found to have varying impacts of fecal contamination   from municipal wastewater sources.
