Understanding Radon in Kanawha County Water: What Area Data Tells Households
This week, your household faces an important decision: determining the next step after your current radon water treatment equipment has failed. Understanding what regional data indicates and what your own water test shows is essential to making a confident choice.
How to Interpret the Median and Range of Radon Levels Reported for Kanawha County
The U.S. Geological Survey sampled six wells in Kanawha County's aquifer 327KNWH between 2010 and 2017. These wells, ranging from 58 to 160 feet deep, showed radon-222 present in all samples. The median radon concentration was 42.5 picocuries per liter (pCi/L), with values spanning from 8.0 to 320.0 pCi/L. This range reflects variations among the sampled wells and should not be applied to your own well without testing. Importantly, none of these samples exceeded federal action levels for radon in water.
What a Certified Laboratory Radon Water Test Report Shows and How to Understand It
A certified laboratory report on radon in water typically provides a measured concentration in pCi/L, along with method details and detection limits. Such a report reflects your specific water source content, which can differ from regional figures. It is the only way to know your household's radon level accurately. Terms like “detected” indicate the presence of radon, not that it exceeds health or regulatory thresholds. If your report shows radon below reporting limits, it means the laboratory did not detect measurable radon under its testing conditions.
Changes in Tap Water After Using a Fleck Radon in Water Filter
The Fleck Radon in Water Filter ships ready to configure and is designed to reduce radon concentrations in household water. After using this system, many users notice a decrease in radon-related concerns at the tap. The treated water typically shows radon levels lowered enough to reduce inhalation and ingestion exposure risks associated with waterborne radon. However, changes such as taste or odor modification are generally minimal because radon itself is a radioactive gas without strong flavor or smell.
The Influence of Plumbing Materials and Age on Radon Presence Separate from Source Water
Radon in water primarily originates from the groundwater source and not from household plumbing. The materials and age of pipes do not generate radon. However, plumbing can influence how radon gas escapes into the air within the home, especially during water use activities like showering or dishwashing. Older or more porous plumbing materials may slightly affect radon off-gassing, but they do not add radon to the water supply itself.
How Radon Enters Groundwater in Kanawha County's Aquifer 327KNWH and the Distribution System
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. In the Kanawha County area, radon dissolves into groundwater as it moves through uranium-bearing formations that feed aquifer 327KNWH. Public water distribution systems might also carry radon if sourced from groundwater, although radon tends to dissipate when water is exposed to air in treatment plants or storage tanks. Thus, radon presence in household water depends largely on the raw source rather than subsequent distribution system processes.
Sample Size and What the Six Well Results Mean for Interpreting Radon Levels
The six-sample dataset represents radon measurements from separate wells within Kanawha County's aquifer and offers a snapshot rather than a comprehensive survey. While this small number helps establish a regional baseline, it cannot capture all local variations or predict the radon concentration in any single well. Homeowners should obtain certified laboratory testing for their own water to understand actual radon levels. This approach accounts for factors like depth, geology, and water table changes unique to their property.
In summary, the U.S. Geological Survey's record covers six wells in Kanawha County's aquifer 327KNWH sampled from 2010 through 2017, showing radon-222 detected in all samples but below federal action levels. These data illustrate regional radon presence without specifying individual household conditions. For water treatment, the Fleck Radon in Water Filter provides a documented method to reduce radon exposure at the tap.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-07-18. 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 327KNWH aquifer (Kanawha County): 6 results from 6 wells, median 42.5 pCi/L, range 8.0-320.0 pCi/L; none above any federal threshold
