Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a group of microbes labs use to gauge how sanitary water is. A positive coliform result can indicate that untreated water is entering your supply through a compromised well, a cross-connection, or a plumbing intrusion — issues that won’t always change taste or odor, so testing is essential. You’ll also see the term total coliforms on many reports, which refers to the wider group of coliform organisms.
In Sewall's Point and surrounding Martin County neighborhoods, responses usually start with confirming any positive total coliform result with repeat sampling, fixing likely entry points, and considering a whole-home barrier for ongoing safety. Total coliforms aren’t the same as E. coli, but they can signal conditions where other microorganisms might be present. Because levels can change, many homeowners prefer treatment at the point the water enters the house so every faucet, shower and appliance is covered.
For coliform bacteria concerns, the single most effective whole-house option is typically a UV disinfection system installed at the main point of entry. UV systems use ultraviolet light to inactivate microorganisms as water flows through the chamber, treating the entire home without adding chemicals. When a unit is sized for your home’s peak flow, UV provides continuous microbial control at every tap — a practical fit for Sewall's Point households seeking broad protection.
UV systems perform best when water is clear, because sediment and heavy mineral scale can shield bacteria from the light; coastal Martin County water is commonly hard, which can contribute to scale in plumbing. That’s why many Sewall's Point homes pair a UV unit with a prefilter to remove sediment and reduce scaling. Mr. Pure Water can size and install the correct UV system for your plumbing, peak demand, and water quality, and provide routine lamp and sleeve service so your whole-house protection for coliform bacteria stays reliable.
