Here’s where it gets fun. Coliform bacteria love warm weather. Your water gets cozier in summer, and they throw a dance party.
Also, they’re incredibly tough. Some can survive in ice or boiling water (briefly). They’re like the cockroaches of the microscopic world. Indestructible party animals.
And get this: A single drop of contaminated water can host millions of coliform. You’d never see them. They’re invisible freeloaders.
Not All Coliform is Created Equal
There’s a distinction you need. Regular coliform is the annoying cousin. Fecal coliform (from poop) is the actual villain.
If your test shows E. coli specifically—that’s the mean one. It means something warm-blooded (like a deer or your dog) used your well as a bathroom. Rude.
But most coliform is just “total coliform.” It’s a heads up, not a death sentence. Think of it as a curiosity call.
