You might think, “Wait, isn’t chlorine a good thing? It keeps me from getting sick.” And you’re right, sort of. But your well has a different security system.
Your well’s water comes from deep underground, where it’s naturally filtered through layers of rock, sand, and gravel. It’s like nature’s Brita filter, but way cooler.
The real superhero here is the soil. As rainwater trickles down, the ground acts like a giant, grumpy bouncer, kicking out most of the nasty bacteria and viruses. So, no chlorine needed.
However, don’t get too comfy. That natural filtration isn’t perfect. You still need to test your water for things like coliform bacteria, nitrates, and other uninvited guests.

Here’s where people get confused. They smell a hint of “bleach” near their well pump. Panic sets in. “THE CHLORINE FAIRIES STRIKE AGAIN!”
Relax. That smell is usually from a chlorine bleach tablet you dropped down the well last year. Or maybe it’s from your water softener’s cleaning cycle.
