Understanding Total Coliform (TC): A Guide for Homeowners
At Dierolf Plumbing and Water Treatment, we believe that knowing what is in your water is the first step to protecting your home and family. If you have recently heard the term “TC Test” or “Total Coliform,” you may have questions about what it means and how it affects your water quality.
What is a TC Test?
A TC Test is a water quality analysis designed to detect the presence of Total Coliform bacteria. This is one of the most standard and important tests performed on private wells and water systems. Because water can look crystal clear and taste normal while still harboring invisible contaminants, a TC test is the only reliable way to confirm your water’s biological safety.

What is Total Coliform (TC)?
Total Coliforms are a large group of related bacteria that are naturally present in the environment—in the soil, on plants, and in surface water. While most coliform bacteria are not harmful themselves, their presence in your well water is a “red flag.”
It indicates that there is a pathway for bacteria to enter your water system. If harmless coliform bacteria can get in, then disease-causing pathogens (like E. coli, viruses, or parasites) can get in too. Think of TC as the “check engine light” for your well.

What Are the Risks?
If your water tests positive for Total Coliform, it is considered “unsanitary.” While many adults might drink water with low levels of bacteria without immediately getting sick, the risk increases significantly for children, the elderly, and those with compromised immune systems.
Symptoms of consuming contaminated water can include digestive issues, nausea, and fatigue. Furthermore, a positive TC result often means your well is vulnerable to surface runoff, insects, or failing seals.

Available Remedies
The good news is that Total Coliform is treatable. At Dierolf Plumbing and Water Treatment, we specialize in permanent solutions to ensure your water is safe 24/7.
- Well Remediation: sometimes, the issue is a physical defect in the well cap or casing that can be repaired.
- Ultraviolet (UV) Disinfection: This is often the gold standard for homeowners. A UV system uses light to neutralize bacteria as water passes through the system, ensuring that living organisms cannot reproduce or cause illness. It is chemical-free and highly effective.

- Chlorination: Another method involves treating the water with chlorine to kill bacteria, similar to municipal water treatment.
