If you’ve recently tested your well water and found coliform bacteria, you’re likely wondering how to handle it.
Well, to remove coliform bacteria from well water, you can use methods such as shock chlorination, UV purification, or filtration systems. These techniques can help disinfect your water supply and ensure it’s safe for drinking.
Seems like a lot? Don’t worry!
In the following blog, we’ll walk you through everything you need to know about removing coliform bacteria from your well water and preventing it from returning.
Read on to find out!
What Are Coliform Bacteria?
Coliform bacteria are a group of microorganisms commonly found in soil, plants, and water. While they are generally harmless, their presence in well water can signal contamination, especially from fecal matter. This indicates that your water may be at risk for other harmful bacteria and pathogens.
Types of Coliform Bacteria
There are three main types of coliform bacteria that may show up in well water tests:
- Total Coliforms: A general indicator of water quality and contamination.
- Fecal Coliforms: These bacteria are found in the intestines of animals and humans, signaling more severe contamination.
- E. coli: A specific type of fecal coliform, some strains of which can cause serious illness if consumed.

Signs Your Well Water Is Contaminated
The only way to confirm the presence of coliform bacteria in your well water is by conducting a water test. You can purchase a water testing kit or send a sample to a certified lab for accurate results.
Here are some common indicators of contaminated water:
- Cloudiness: The water may appear murky or contain sediment.
- Bad Taste or Odor: Contaminated water can have an unusual or unpleasant taste and smell.
- Presence of Sediment: Visible particles may appear in the water.
N.B: If you notice any of these signs, it’s time to test your water immediately.
Proven Methods to Remove Coliform Bacteria from Well Water
Once you’ve confirmed the presence of coliform bacteria, it’s crucial to take action. Here are some effective methods for removing coliform bacteria from well water.
Chlorination (Shock Chlorination)
Shock chlorination is one of the most reliable and widely used methods for disinfecting well water. This process involves introducing chlorine (usually household bleach) into the well to kill bacteria.
Step-by-Step Process
- Turn off the water supply to prevent water usage during the chlorination process.
- Pour a specific amount of chlorine bleach into the well (the amount depends on your well’s size).
- Run faucets throughout the house until you smell chlorine at each one. This circulates the treated water.
- Let the chlorine sit in the system for several hours (usually 12-24 hours) to fully disinfect the well.
- Afterward, flush the system by running the water until the chlorine odor disappears.
Best Practices: Always test your water again after chlorination to ensure the bacteria have been fully eradicated. Shock chlorination is effective, but additional treatments may be required in cases of severe contamination.
Ultraviolet (UV) Water Purification
UV water purification is a chemical-free way to kill bacteria and other pathogens in well water. This system uses ultraviolet light to neutralize bacteria by disrupting their DNA.
How It Works: The UV system is installed where the water enters your home. As the water flows through the system, UV light kills harmful microorganisms, preventing them from reproducing or causing illness.
Best Uses: UV systems are ideal for homes with ongoing bacterial contamination. They require little maintenance and offer continuous protection.
Extra Note: UV systems don’t remove sediment or chemicals, so it’s best to pair them with a filtration system for comprehensive water treatment.
Filtration Systems
Filtration systems, such as reverse osmosis (RO), physically remove coliform bacteria from your water. These systems are designed to filter out contaminants, leaving you with clean, safe drinking water.
How It Works: Water passes through a semi-permeable membrane that traps bacteria, viruses, and other impurities. Clean water flows through, while contaminants are left behind.
Best Practices: Reverse osmosis systems require regular maintenance, such as changing the filters, to remain effective. They can also remove other contaminants like chemicals, making them an excellent all-around solution for water purification.
Boiling Water
Boiling water is an effective short-term solution to eliminate coliform bacteria.
Step-by-Step Process
- Bring water to a rolling boil for at least one minute (or three minutes if you’re at a higher elevation).
- Allow the water to cool before using it for drinking, cooking, or cleaning.
Best Practices: While boiling is a great immediate solution, it’s not practical for long-term use. It’s best to implement one of the other methods for continuous protection of your well water.
Long-Term Prevention of Coliform Bacteria in Well Water
After successfully removing coliform bacteria from your well water, it’s essential to take steps to prevent it from returning. Regular maintenance and preventive measures can help ensure that your water remains safe over time.
Here are a few key strategies to consider:
Regular Water Testing
Regular testing is the best way to stay ahead of potential contamination. It’s recommended to test your well water at least once a year, and more frequently after events like heavy rainfall, floods, or construction near your property. This ensures early detection of any bacterial presence.
Well Maintenance and Sealing
Proper well maintenance is crucial for keeping out contaminants. Ensure that your well is tightly sealed, with no cracks in the cap or casing. Regular inspections of the well’s structure can help prevent bacteria from seeping into the water supply.
Installing a Water Treatment System
Consider investing in a permanent water treatment system, such as a UV purifier or filtration system. These systems provide ongoing protection by killing bacteria or filtering out contaminants, ensuring that your well water stays safe for long-term use.
Concluding Words
Coliform bacteria in well water can be a serious concern, but with the right treatment, you can ensure your water is safe to drink.
From shock chlorination to UV purification and filtration, there are several effective methods to remove bacteria and prevent future contamination.
Besides, regular water testing and well maintenance are always the ultimate key to protecting your water supply.
