Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a group of microorganisms commonly used to judge water sanitation. If a lab test flags coliform bacteria, it can mean that untreated or contaminated water is entering the system through a compromised well, a plumbing cross‑connection, or other intrusion. Often there’s no change in taste or odor, so testing is the only way to know. You may also see your results labeled as total coliforms, which refers to the broader coliform group.
In Frog City houses, responses to a total coliform detection usually start with confirming the result through repeat sampling, fixing any likely entry points, and adding a whole‑home barrier to protect every tap. Total coliforms aren’t the same as E. coli, but their presence can indicate conditions that allow other microbes to be present. Because readings can fluctuate, many homeowners prefer treatment at the point of entry so the entire home—including showers, drinking water and appliances—is covered.
For coliform bacteria, the single most effective whole‑house filter is typically a UV disinfection system installed at the point where water enters your Frog City home. Ultraviolet light inactivates microorganisms as water passes through the chamber, treating every outlet without adding chemicals or changing taste. When the UV unit is sized for your home’s peak flow, it provides targeted microbial control across the entire plumbing system.
UV systems work best when water is relatively clear because heavy sediment can block the light; that’s why many Frog City homes pair UV with a sediment prefilter. If you want one primary technology to address total coliforms, UV is the reliable workhorse. Mr. Pure Water will help select and size the UV unit for your plumbing and demand, and with routine lamp and sleeve maintenance it delivers dependable whole‑house protection against coliform bacteria.
