Including filter system and high-performance PFOS filter.
PFOS is one of the PFAS chemicals that can persist in the environment and sometimes shows up in drinking water. Because it breaks down very slowly, small releases over time can lead to a continuing presence in a water source. Black Hammock homeowners—many of whom rely on private wells around Lake Jesup and the nearby St. Johns River—often hear about PFOS through testing, local reports, or news. If you’re worried, the next sensible steps are to test your water and choose a treatment designed specifically for PFAS compounds.
PFOS usually has no taste, smell, or visible sign, so you can’t count on your senses to know whether it’s in your water. That’s why long-term exposure is the main concern rather than an immediate nuisance like iron or sulfur odors some Black Hammock well owners experience. Treating water where it enters the house — so treated water reaches drinking, cooking, bathing, and laundry — is a practical way to lower PFOS exposure throughout your home.
For whole-house reduction of PFOS, the most effective single solution is a high-capacity granular activated carbon (GAC) system formulated for PFAS. GAC removes PFOS by adsorbing it onto the media’s large internal surface as water flows through. Because PFOS is tougher to remove than common taste-and-odor issues, the quality of the carbon, adequate bed depth, and correct flow rates are important. A properly sized whole-house GAC unit can treat an entire Black Hammock home without needing multiple under-sink units.
A whole-house GAC filter is plumbed on the main water line so every faucet and appliance gets treated water — useful in our hard-water Black Hammock homes where scale and odors from iron or sulfur can also be concerns. To maintain PFOS reduction, choose a system sized for your household peak flow and follow scheduled media replacements. Mr. Pure Water can recommend a whole-house carbon setup matched to your plumbing and usage, and follow-up testing before and after installation gives added assurance the system is performing.
