How Do You Get Rid Of Coliform In Well Water

Oh, the joys of homeownership, am I right? You test your well water, expecting pure, crystal-clear bliss from the earth.

Instead, you get a report that says “Coliform bacteria present.” Cue the dramatic music. Don’t panic yet—let’s fix this.

First, let’s get friendly with the enemy. Coliform is just a little bug that might mean something nastier is lurking.

Think of it as that one friend who always shows up uninvited to a party. It’s not the problem itself, but it hints the door is unlocked.

Now, how do you kick coliform out? It’s not magic, but it’s close—and way cheaper than a witch doctor.

Step 1: Go on a Manhunt (The Source)

Before you nuke your well, find out why coliform got in. Is your well cap cracked? Check it.

Is there a cute little puddle of runoff sneaking in? Eww. Fixing the entry point is step one.

Sometimes it’s just a dirty screen or a loose wire. You’d be surprised what a tightened cap can do. It’s like putting a lid on a jar of chaos.

Shock Chlorination: The Nuclear Option (That’s Actually Mild)

This is the classic fix. Think of it as a bath bomb for your well, but with bleach.

You pour a calculated amount of household bleach down the well. Then you let it sit for a few hours, like a very aggressive marinade.

Then you flush it all out. Poof—bye-bye, bacteria. Just don’t use scented bleach; your water doesn’t need to smell like “Summer Breeze.”

Pro tip: run your outside hoses first to avoid blasting bleach through your kitchen faucet. Your coffee doesn’t need a chlorine kick.

Step 2: The Continuous Disinfection Gadgets

If coliform keeps coming back like that ex you can’t shake, you need a permanent solution. Enter the UV light system.

It’s like a tanning bed for your water pipes, but it zaps bacteria dead without chemicals. No taste, no smell, just clean water.

You install it after your pressure tank. The water flows past this intense light, and coliform gets fried. Mwah—clean victory.

Another option is a chlorine injector pump. It adds a tiny, controlled dose of bleach to your water line.

It’s like a bartender for your tap, but instead of vodka, it’s chlorine. You’ll need a contact tank to let it work, but it’s rock-solid.

How to Treat and Eliminate Coliform Bacteria in Well Water

The Filtration Fairy Tale

Filters alone don’t kill coliform. They just catch dead bodies. You need a kill step first, then the filter polishes things up.

Think of it as catching the zombie before it bites. Filter first, then disinfect is the wrong order.

Always disinfect before the filter. Otherwise, you’re just giving bacteria a cozy home in your expensive carbon block.

Step 3: The Water Test Dance

After you shock or install a system, wait a week. Then test again. Do not skip this—I’m looking at you.

You need to see if you actually won. If coliform is still there, your well might have a hidden crack or a bad seal.

It could also be something silly, like a dirty sampling tap. Sanitize that faucet first before you collect the sample. Common sense saves headaches.

Step 4: The Deep Fix (Septic or Geology Issues)

Sometimes coliform is a sign that your septic system is too close to your well. That’s not a DIY fix.

You’ll need a pro to inspect both. Yes, it costs money. But so does drinking bacterial soup—pick your poison.

Or, maybe your well is drilled into shallow groundwater. In that case, deepening the well or installing a double-cased liner might be the only fix.

Don’t pretend you can’t hear me. Call a licensed well driller. They’ve seen it all, including weirder stuff than your coliform.

What About Boiling?

Boiling works in a pinch. It’s your emergency plan during a power outage or system failure. But boiling every glass of water? That’s exhausting.

You’d never leave the kitchen. Bye-bye, social life. So, boil for camping trips, not for daily life.

Final Sip of Wisdom

Getting rid of coliform isn’t rocket science, but it does require you to stop guessing and start acting. Test, fix the breach, disinfect, and filter.

You’ll feel like a superhero when that clean test comes back. “Yeah, I vanquished coliform. No big deal.”

Remember: regular testing is your best friend. Do it yearly, like your dentist appointment, but much less painful. You got this.
