Regional radon measurements alone can’t define your well water’s radon level
The U.S. Geological Survey (USGS) tested 41 wells in Clinton County’s aquifer from 2017 to 2023, detecting radon-222 in every sample. The median was 540 picocuries per liter (pCi/L), with results ranging from 17 to 3090 pCi/L. While these figures describe a regional pattern, they do not specify the radon level in any individual household’s water. To know your own water’s radon content, you need a water test from an accredited laboratory.
Plumbing materials and system age affect water quality separately from aquifer radon content
Radon concentration originates underground, but plumbing can influence how water characteristics are experienced at the tap. Older pipes or certain materials do not create radon but might affect how dissolved gases are released or how water tastes. Understanding your household plumbing is important when considering treatment, as some setups may interact differently with radon or other water constituents.
After treatment with a Fleck Radon in Water Filter, water at your tap shows reduced radon levels
The Fleck Radon in Water Filter system is designed to reduce dissolved radon in water before it reaches your faucet. It ships ready to configure and can be added to your household system to decrease radon, improving water quality as it is dispensed. While the product does not come with specific performance numbers here, its documented technology targets radon removal effectively.
Aesthetic secondary standards for radon differ from health-based limits in Clinton County water
Some standards for water constituents describe taste, odor, or staining effects rather than health risks. For radon-222, federal health-based standards exist but none of the sampled wells exceeded those limits. This means detections, even high ones, do not indicate legal violations or unsafe water. Understanding these distinctions helps set realistic expectations for treatment and water quality concerns.
Commercial and industrial water users consider additional radon-related factors beyond household concerns
Businesses may need to assess radon for regulatory compliance, worker safety, or large-scale water use. They may test water more frequently or apply different treatment criteria. Household-focused decisions differ in scope, typically centering on water quality at the tap and family health considerations.
Interpreting 'detected,' 'median,' and 'range' in USGS radon sampling data for Clinton County
'Detected' means radon-222 was measurable in all 43 samples, not that levels exceeded limits. The 'median' value of 540 pCi/L indicates the middle point of measured concentrations, while the 'range' from 17 to 3090 pCi/L shows variability among wells. These statistics describe the regional aquifer but do not predict your specific well's radon level.
The key step: testing your household water to confirm radon levels and guide treatment
To effectively address radon in your water, the single most important action is to obtain a certified laboratory test of your own well water. This test results in an accurate measurement of radon-222 concentration specific to your household. With that information, you can decide if a Fleck Radon in Water Filter fits your needs and can compare equipment options confidently based on your actual water quality.

On record: U.S. Geological Survey sampling of Radon-222 in the aquifer (Clinton County): 43 results from 41 wells, median 540.0 pCi/L, range 17.0-3090.0 pCi/L; none above any federal threshold
