You have options, and none of them involve waving a magic wand—though that would be awesome. Let’s break down the three most common ways to kick coliforms out of your water supply. Spoiler: you can handle these like a pro.
1. Boiling: The Old Reliable
Boiling is the nuclear option for lazy people—and I mean that as a compliment. Bring your water to a rolling boil for at least one minute (or three minutes if you’re above 6,500 feet, because science is picky).
This kills coliforms instantly, like a hot tub for germs. But here’s the catch: you can’t boil your entire well or city supply. So this works for drinking and cooking, but not for your morning shower singalong.
2. Chlorination: The Pool Party Method
Chlorine is the bouncer of the water world. It grabs coliforms by the scruff and kicks them out. You can buy liquid household bleach (unscented, no fancy additives—your water doesn’t care about “ocean breeze” scent).
Add about 8 drops per gallon, let it sit for 30 minutes, and boom—bacteria-free. If you’re treating a whole well system, you’ll need to do a shock chlorination, which is as fun as it sounds. Just follow the directions on a test kit, and try not to smell like a swimming pool for a week.

3. UV Light: The Sci-Fi Solution
Ultraviolet light systems are like tiny suns for your pipes. They zap coliforms dead without adding chemicals or weird tastes. No boiling, no bleach—just pure, invisible light that makes bacteria feel very unwelcome.
Install a UV unit in your water line, and it’ll work 24/7 like a superhero on overtime. The only downside? You need clear water, so filter out mud or rust first. Otherwise, UV light is basically shining a flashlight through a dirty sock.
