cyklon_300:You may be confusing Total coliform content with Fecal/E. coli results. In terms of drinking water analyses, sample results that are TC+ are not considered to be an immediate health hazard. The Total coliform test is simply an indicator that if a water source can support the growth of these ubiquitous organisms, then it may also support pathogenic organisms.
Conversely, samples that are Fecal/E. coli positive are deemed to have been in direct contact with mammalian waste products.
You're probably right there. I haven't had a refresher on the specific microbiological lingo since the late '90's. My apologies.
Boogie, the Walkerton incident is dated year 2000, so my training predates it. Funny... it still should have crossed my desk or been referred to me. I guess a lot of what happens in Canada never makes it to Texas. :11ztongue
From the news report I hastily pulled up, excess rainfall overloaded the town's treatment capability. The system was maintaining minimum (or below minimum) secondary treatment to begin with, and the agricultural runoff completely overwhelmed it. Is that an accurate assessment?
