Including filter system and high-performance PCBs filter.
PCBs are industrial chemicals that persist in the environment and sometimes turn up in water supplies; they’re also called polychlorinated biphenyls. These compounds were commonly used in older electrical gear and manufacturing, and when they reach waterways they can be slow to break down. Bascom homeowners typically hear about them from water reports, neighbors, or private testing, and may reasonably want to know how to reduce their presence at home.
Because PCBs are usually present at very low concentrations, you won’t detect them by sight, smell, or taste in your tap water. They can get into sources through historical contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even if Bascom’s water looks clear, many families prefer a whole-house strategy to limit long-term exposure and to treat all uses—cooking, bathing, laundry—not just a single faucet.
The best single-filter option for a whole-house system to address PCBs is a high-quality activated carbon filter, typically a catalytic carbon or carbon block designed for strong adsorption. PCBs are hydrophobic organic compounds, so they’re much better captured by carbon media than by simple sediment filters. As water flows through the carbon, polychlorinated biphenyls can adhere to the media and be reduced before reaching your Bascom taps, while the system also helps lower other related organic contaminants.
For reliable PCB reduction, a carbon filter needs sufficient contact time and enough media for your home’s flow rate so it can perform during busy household use. A sediment pre-filter is commonly installed ahead of the carbon to prevent premature clogging, but the carbon stage is the key component. Proper sizing and routine media or cartridge changes matter because adsorption capacity declines over time; Mr. Pure Water can help Bascom homeowners choose and maintain a whole-house carbon system sized for their plumbing and usage.
