Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals—also called polychlorinated biphenyls—that resist breaking down and can linger in the environment. These compounds were commonly used in older electrical gear and certain manufacturing, and when they reach waterways they can persist at low concentrations. Middle River homeowners typically hear about PCBs from utility notices, neighborhood conversations in areas like Fruit Cove or Durbin Crossing, or from independent testing, and may want to understand how these persistent contaminants behave in local water sources.
Because PCBs usually occur at very low concentrations, you won’t detect them by sight, smell, or taste in tap water. They can enter water supplies through legacy contamination, disturbed sediments, or runoff that carries pollutants into rivers and creeks around St. Johns County. Even when your water appears clear, many Middle River families choose to address potential long-term exposure across all household uses—cooking, bathing, laundry—so a whole-house solution treats every faucet rather than a single point-of-use.
For whole-house removal of PCBs, the most effective single-filter option is a high-quality activated carbon unit—typically catalytic carbon or a tight carbon block—because PCBs are hydrophobic organic compounds that adsorb well to carbon media. As treated water flows through the carbon bed, polychlorinated biphenyls cling to the carbon surface rather than passing on to your plumbing. A properly selected whole-house carbon system also helps reduce many other organic contaminants that often travel with PCBs into local waterways like the St. Johns River and nearby creeks.
To be effective in a Middle River home, an activated carbon PCB filter needs sufficient media volume and contact time to handle your household flow—especially important in Northeast Florida where hard water and limescale from fixtures can be a concern. A sediment pre-filter is commonly paired upstream to protect the carbon from early fouling, while routine media or cartridge changes maintain adsorption capacity. Mr. Pure Water can size and install a whole-house carbon system matched to your home and plumbing so PCBs are treated at the point where water enters your house.
