How Fleck Radon in Water Filter Removes Radon from Household Water
Radon reduction by air stripping and filtration
The Fleck Radon in Water Filter uses a system designed to remove radon-222 gas dissolved in water by forcing water through media that promote radon release from water to air, effectively reducing radon levels before household use.
Neutralizing radon without chemicals
This approach decreases radon concentrations through physical processes rather than chemical additives, providing a consistent reduction method suitable for residential water treatment.
Understanding Aesthetic Secondary Standards Versus Health-Based Limits for Radon
Radon levels measured in Tyler County reflect gas presence, not taste or odor issues
The measured radon concentrations relate to radiological risk and are regulated under federal health-related guidelines, not aesthetic parameters like taste or staining, which differ for other water constituents.
Health-based limits govern radon, distinct from secondary standards for other water issues
Secondary standards address issues affecting appearance and taste but are not applicable to radon, which is subject to distinct federal recommendations focused on health exposure risks.
Maintenance Rhythm of the Fleck Radon in Water Filter
Regular media replacement
The radon-reducing media within the Fleck system requires periodic replacement to maintain effective radon removal, with intervals depending on household water usage and radon load.
System monitoring and periodic check-ups
Users should monitor system performance routinely to ensure radon levels remain reduced, evaluating water quality through testing as needed to inform maintenance timing.
Seasonal and Multi-Year Variation in Radon Concentrations
USGS samples in 2018 show radon concentrations over two consecutive days
Three wells sampled in Tyler County’s aquifer 317DKRD between June 18–19, 2018, showed radon concentrations ranging from 1,220 to 1,700 picoCuries per liter, indicating some short-term variation within a small sampling window.
Seasonal or longer-term trends cannot be determined from limited data
These measurements provide a snapshot rather than long-term patterns, so households should consider testing their own water for seasonal changes impacting radon levels.
Meaning of Measured Radon Range Against Federal Standards
Recorded Tyler County samples are below any federal maximum contaminant level
All three radon results from wells 80 to 150 feet deep fall beneath federal health-based thresholds, showing no exceedance in the sampled area.
Detection does not imply individual well water matches area data
While the regional data informs about the aquifer’s characteristics, only testing a household’s own well water can confirm its radon concentration and treatment needs.
These findings reflect U.S. Geological Survey groundwater sampling of the Tyler County aquifer 317DKRD area and do not substitute for a household’s own water quality testing. For details, visit the USGS monitoring location 392429080551301.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2018-06-19. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of Radon-222 in the 317DKRD aquifer (Tyler County): 3 results from 3 wells, median 1500.0 pCi/L, range 1220.0-1700.0 pCi/L; none above any federal threshold
