Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a group of microorganisms used by labs to judge how sanitary a water supply is. A positive coliform result in Lafayette can indicate that untreated surface or well water is entering your plumbing through a damaged well, a cross-connection, or a breach somewhere in the system. Because coliforms often don’t change taste or smell, homeowners rely on testing to spot them—reports may use the phrase total coliforms to describe the broader group.
When total coliforms show up in testing, the usual steps are to retest, address potential entry points, and consider adding a whole-house barrier for continuous protection. Total coliforms aren’t the same as E. coli, but their presence can signal conditions that allow other microbes. Lafayette homeowners commonly choose treatment at the point where water enters the house so every faucet and appliance benefits from the same protection.
For coliform bacteria, the single most effective whole-home option is typically a UV disinfection system installed at the point of entry. UV systems in Lafayette inactivate microorganisms as water flows through the chamber, treating the entire house without chemicals. Because ultraviolet light targets microbes directly rather than masking tastes or odors, a correctly sized UV unit provides reliable protection at every tap when matched to your home’s peak flow.
UV works best on clear water since heavy sediment can block the light, so many Lafayette homes pair a UV unit with a prefilter. If you’re selecting one primary technology specifically for total coliforms, UV is the proven workhorse. Mr. Pure Water can size and install the right UV system for your plumbing and demand, and with routine lamp and sleeve maintenance it delivers dependable whole-house protection against coliform bacteria.
