We just got our results back from the lab, and apparently, our water isn't safe to drink. The report mentions two different types of bacterial colonies—specifically the 22°C / 72-hour and 37°C / 48-hour stuff. The official paperwork says it doesn't meet safety standards, yet someone told us verbally that it's perfectly fine to drink. Honestly, I'm completely lost here. Any advice would be huge. Thanks.
Those "colonies" are bacterial colonies, most likely, and it looks like they tested their resilience at two different temperatures.
My guess is that when they told you it was okay to drink, they were implying that if you live there and have been drinking it for a while without getting sick, you've probably built up some kind of immunity to those specific bacteria.
Personally, though? I wouldn't touch that water.
I don't know what the standard protocol is for drafting these lab reports, but in my book, failing to specify exactly what was found is just plain unprofessional.
