Radon In Water Reduction - Spruce Environmental Technologies

Radon In Water Reduction

Radon in water, when released as a gas into the air from faucets, showers and other sources, can contribute to the amount of radon you breathe. According to the U.S. Environmental Protection Agency (EPA), "Some people who are exposed to radon in drinking water may have increased risk of getting cancer over the course of their lifetime, especially lung cancer." There are two most commonly used types of waterborne radon reduction systems: aeration and granular activated carbon (GAC). A primary factor in choosing between these systems is the radon level. The EPA, for example, does not recommend GAC for radon levels above 5,000 pCi/L. However, a GAC system uses one, two or three carbon beds or tanks onto which the radon is adsorbed. When properly installed and serviced, it can be effective. If used improperly or if the tanks are left in place too long, the carbon may become ineffective and/or may become a source of radioactivity. Spruce AIRaider™ Systems use the aeration method for reducing radon in water, which is considered by the EPA to be the "best available technology (BAT)." Aeration does not pose the threat of waste buildup that other methods, such as GAC, might pose. Aeration separates the radon gas from the well water, and then vents the contaminants safely above the roofline. To select and install the correct AIRaider™ System, generally a certified radon mitigator who is experienced in waterborne radon reduction will: assess the waterborne radon level; recommend full
