Once you’ve cleared the bacteria, make sure they stay gone. Slope the ground around your well away from the casing—water should drain, not pool. Keep pesticides, manure, and lawn chemicals at least 50 feet away. And for the love of all that is holy, don’t let your dog do its business near the wellhead. I’m looking at you, Fido. Test your water annually, even if you think it’s fine. It’s cheaper than a case of the trots.
Also, get a UV filter if you’re paranoid (or have a high water table). UV light zaps bacteria without chemicals—like a tanning bed for germs. It’s an upfront cost, but it’s the roach motel of water treatment: they check in, they don’t check out. Pair it with a sediment filter to catch the debris first. Your water will taste like nothing, which is exactly what you want.
Treating a well with coliform is a bit like house-training a stubborn puppy: messy, frustrating, but totally possible with patience. You’ll learn more about your plumbing than you ever wanted to know, and you’ll develop a newfound respect for the invisible world living in your pipes. And honestly? After that first glass of clean, bacteria-free water? You’ll feel like a god of hydro-engineering. Just, uh, maybe don’t let your geologist neighbor visit unannounced. Trust me on that one.
