Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a group of microbes commonly used to indicate water sanitation. If a lab report shows coliform bacteria it may mean untreated water is entering the system through a damaged well, a plumbing cross-connection, or another intrusion point. These organisms often don’t change taste or odor, so test results are important to interpret. You may also see the term total coliforms on your analysis, which refers to the broader set of coliform organisms.
In Garnier homes, a typical response to finding total coliforms is to repeat testing, eliminate possible entry routes, and add a whole-house barrier to protect every tap. Total coliforms are distinct from E. coli but can indicate conditions where other microbes might occur. Because levels can fluctuate, many homeowners in the area prefer treatment at the point of entry so showers, sinks and appliances all receive the same protection.
For coliform bacteria, the single most effective whole-house option is usually a UV disinfection system installed at the main water entry. Ultraviolet light inactivates microorganisms as water flows through the chamber, treating the entire house without adding chemicals. This method directly targets bacteria rather than relying on taste- or odor-focused media, and when the unit is sized for your home’s flow it can deliver consistent protection to every faucet in Garnier.
UV systems perform best when water is relatively clear, since heavy sediment can reduce light penetration and shield organisms. For that reason, many homeowners pair UV with a prefilter, but if you want one primary technology specifically for total coliforms, UV is the go-to choice. Mr. Pure Water can help select and size a UV unit for your Garnier plumbing and peak demand, and with proper installation plus routine lamp and sleeve maintenance, UV provides reliable whole-house protection against coliform bacteria.
