This paper summarizes selected data from a pathogen monitoring program in the Grand Riverwatershed in Southern Ontario, Canada. The indicators/pathogens discussed in the paper include: fecalcoliforms, E. coli, E. coli O157:H7, and Campylobacter spp. Data is presented for one year ofmonitoring. Fecal coliforms were found in 95 to 100% of all samples and E. coli were found in91 to 100%. Campylobacter was less prevalent but was found in 59 to 85% of all samplesnonetheless. E. coli O157:H7 was isolated and confirmed in a five-step process. While the"presumptive" tests showed that it may be present in 32 to 59% of samples and "confirmed" testsshowed it to be present in 2 to 14% of all samples only 0 to 7% of samples were carried throughto the "complete" stage. It appears as if Campylobacter is more common than may have beenpreviously expected. E. coli O157:H7, on the other hand, is perhaps not as common explainingwhy the interruption (or inadequacy) of drinking water disinfection systems does not lead tomore frequent outbreaks of this pathogen. Includes 6 references, tables, figures.
