Government sampling in Chambers County, Texas, has measured radon-222 levels in groundwater wells drawing from aquifer 112CHCTU. These results provide context for households concerned about radon in their water but cannot specify the radon concentration in your personal well. Water quality varies from well to well, so individual testing is essential for informed decisions.
If you operate commercial or industrial water systems
Commercial or industrial water users face different demands and potential exposure risks than residential users. They may require more detailed exposure assessments and greater treatment capacity, as well as compliance with specific regulations not applicable to single residences. This page focuses on household water use and treatment considerations.
If you are gathering information before seeking treatment options
Before exploring water treatment technologies, note the following about your own water situation:
- Have you tested radon concentration in your well water, preferably through certified laboratory analysis?
- What is your household’s daily water use volume?
- Do you have any current water treatment equipment related to radon? If so, what is its capacity and condition?
- Are other potential sources of radon exposure, such as soil gas infiltration, being addressed in your home?
Gathering this information helps assess whether additional water treatment capacity may be needed.
If you want to rule out other causes of water quality or health concerns before testing for radon
Because radon in water is odorless and tasteless, symptoms or indicators of radon exposure from water are often non-specific. It is practical to check for more common water quality problems first, such as sediment, iron staining, or microbial contamination. Only after ruling out these more frequent issues should radon testing be prioritized. Starting with a certified water test for radon is the definitive way to know your water’s radon level.
If you have heard radon is common in Chambers County and want to compare with nearby areas
U.S. Geological Survey sampling of wells in Chambers County’s aquifer 112CHCTU found radon-222 at median concentrations near 268 pCi/L across three wells sampled at depths between 42 and 166 feet in August 2014. Neighboring counties may show different radon levels due to geology and source variations, but this does not predict individual well conditions. Use area data only as a reference point and not as a substitute for individual testing.
If you need to assess whether your household’s water treatment equipment can keep pace with daily radon reduction needs
Effective radon removal from water depends on matching treatment capacity to the household’s daily water consumption. If your current equipment seems unable to maintain radon at desired levels, it may be undersized or require upgrading. The Fleck Radon in Water Filter system is designed to handle typical residential demands and can be considered as an option that ships ready to configure. Determining the appropriate system size requires knowledge of your water usage and radon concentration.
To summarize, government sampling in Chambers County’s aquifer 112CHCTU in 2014 established radon-222 presence ranging from 136.0 to 290.0 pCi/L in three wells. These values do not indicate any federal limit exceedance, nor do they describe any individual well’s water. Testing your own well water and matching treatment capacity to your household’s demand are key steps.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-08-19. 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 112CHCTU aquifer (Chambers County): 3 results from 3 wells, median 268.0 pCi/L, range 136.0-290.0 pCi/L; none above any federal threshold
