Including filter system and high-performance E. coli filter.
Finding E. coli in household water is a warning that bacteria may be entering the system somewhere between the source and your taps. In Pelican Marsh and the greater Collier County area, contamination can occur for the same reasons it does elsewhere: breaks in distribution lines, plumbing cross-connections, or vulnerable private wells that allow human or animal waste to reach the supply. Water that looks clear can still harbor microbes, and many Naples-area homeowners only discover a problem after routine testing, a public advisory, or persistent water-quality issues.
You may also see references to E. coli O157, a strain noted for causing more serious illness. Whether a lab flags general E. coli or E. coli O157, the priority for Pelican Marsh households is preventing bacteria from getting into the water you drink, cook with, and bathe in. Temporary measures like boiling water help at a single faucet, but they don’t protect the whole house. A whole-home strategy keeps treated water consistent across kitchens, bathrooms, laundry rooms and showers in your Pelican Marsh residence.
For point-of-entry control in Pelican Marsh homes, the most effective single-filter option for addressing E. coli is a whole-house ultraviolet (UV) disinfection system. Installed where water enters the house, a UV unit uses ultraviolet light to inactivate microorganisms as water flows through the chamber. Because UV works continuously and without chemicals, it can protect all fixtures and appliances at once, which is useful when the main concern is bacterial contamination rather than taste or mineral scale.
UV performs best when the incoming water is clear enough for light to pass through, so Pelican Marsh homes—where southwest Florida supplies often run hard and carry sediment—commonly pair UV with a sediment prefilter. With correct sizing for your home’s flow rate and routine lamp and sleeve maintenance, a UV system can deliver steady protection against E. coli and other bacteria without adding a disinfectant taste, making it a go-to choice when bacterial risk is the focus.
