Let’s be real. This is fun to talk about because it’s so weird. Your water has a secret life. It’s a little ecosystem under your feet.
The main risk? If coliform gets in, other nasties might too. Like viruses or parasites. But mostly, it’s just a sign your well needs a tune-up.
So, is it common? Emphatically yes. It’s as common as finding a spider in your basement. Startling, but usually manageable.
The Fix is Easier Than You Think
You don’t need to burn your house down. First, retest. Sometimes it’s a false alarm from a dirty sample jar. Rinse better.
Next, shock chlorinate your well. That’s a fancy way of saying “dump bleach in there and flush it out.” It’s oddly satisfying. Like giving your well a spa day.
Also, check your well cap. A loose or cracked cap is an open door for critters. A squirrel might have thrown a party on your wellhead. Seal it up.
