Deep private wells drilled into Western North Carolina's granitic bedrock frequently tap aquifers laden with dissolved radioactive radon gas. When you take showers, wash dishes, or run laundry, dissolved radon is aerosolized into the air you breathe inside your home. We install whole-house diffused bubble water aeration systems at the point of entry that eliminate up to 99 percent of waterborne radon safely.
We install specialized non-pressurized aeration holding tanks (such as Air-Zone or RadonAway AIRaider systems) where water enters the home. A high-output air blower vigorously bubbles filtered outdoor air through the incoming water, stripping dissolved radon gas out of solution instantly.
The stripped radon gas is not released into your home. A dedicated sealed vent line carries the radioactive gas out of the aeration chamber and exhausts it safely above the roofline using an auxiliary blower fan, preventing indoor air re-contamination.
Because aeration tanks operate at atmospheric pressure, water must be repressurized for household distribution. Our systems incorporate an integrated stainless steel jet pump and pressure tank that restores full 50–60 PSI domestic water pressure to all fixtures.
Fine mountain well grit and dissolved minerals can foul aeration nozzles. We install multi-stage sediment pre-filters and iron filters ahead of the aerator, protecting aeration orifices and ensuring uninterrupted water treatment reliability.
For every 10,000 pCi/L of radon in your well water, approximately 1.0 pCi/L is transferred directly into your indoor air during normal household water use, primarily from hot showers and dishwashers.
While carbon filters trap radon, the decaying radon accumulates inside the carbon bed, turning the tank into a radioactive waste hazard. Aeration vents radon safely outdoors without dangerous radioactive buildup.
The EPA recommends mitigation for private well water testing above 4,000 pCi/L, although many mortgage lenders mandate treatment at levels above 2,000 to 5,000 pCi/L.
