If You Have Not Yet Tested Your Water for Radon
Data from U.S. Geological Survey samples in the Umatilla County aquifer N600CMBPLV provide a picture of radon-222 presence in the region’s groundwater. However, these area results cannot reveal the specific radon level in your household’s water supply. Since radon concentrations can vary significantly even between nearby wells, testing your water through a certified laboratory is the most cost-effective and reliable first step. This test will establish your actual radon level, allowing you to determine if treatment is advisable.
If You Have Considered the Regional Sample Size and Data Range
The radon-222 figures that characterize this area come from three separate groundwater wells sampled over a two-week period in 2016. The median radon concentration was 203.0 pCi/L, with individual results ranging from 110.0 to 450.0 pCi/L. While useful for understanding regional trends, this small sample size means the data represents a limited snapshot rather than a comprehensive survey. Consequently, the range indicates radon variability, but does not predict your household’s precise exposure.
If You Operate a Commercial or Industrial Facility
Businesses face additional considerations beyond those of households, such as regulatory compliance, larger volumes of water use, and potential radon release during processes. Although the radon data for Umatilla County are limited to a few residential wells, commercial operators should consult specific testing protocols and possibly conduct more frequent or specialized radon assessments to ensure operational safety and meet any regulatory guidelines.
If You Want to Interpret Median and Range Radon Data for Your Home
As a homeowner, you can view the median value as the middle ground among sampled wells in your aquifer, while the range shows the highest and lowest recorded radon levels. If your own water test shows radon near or above this range, treatment may be more urgent. Levels below 110.0 pCi/L, based on these samples, suggest a lower regional presence, but only a direct test of your water confirms your home's status.
If Your Household Experiences Symptoms or Signs Possibly Linked to Waterborne Radon
Radon in water is radioactive but does not cause immediate taste, odor, or visible effects in water. It also does not produce skin or respiratory symptoms directly from water use. Instead, radon gas released during household water use can increase indoor air radon levels, a separate concern better addressed through air testing. Therefore, no common household symptoms indicate radon presence in water.
If You Wonder Which Household Fixtures or Uses Are Most Affected by Radon
Radon enters indoor air primarily from water used in showers, washing machines, and faucets where agitation promotes gas release. The quantity of radon entering air depends on water radon concentration and the volume of water exposed to air. Thus, fixtures with high water agitation release more radon gas. Household drinking water and cooking are less significant sources of indoor radon exposure.
Testing Your Water: The Essential Step Before Deciding Treatment
Because U.S. Geological Survey results reflect area-level data only, the single most important action is obtaining a laboratory test of your home’s water for radon-222. This test clarifies your water’s condition and guides treatment decisions. Should your test reveal radon levels warranting mitigation, the C-Series Radon in Water Filter ships ready to configure and is designed specifically to reduce radon concentrations in household water. This technology offers a documented solution that you can compare against other technical approaches based on effectiveness and fit for your water conditions.

Source: USGS groundwater sampling. Sampled 2016-08-10. 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 N600CMBPLV aquifer (Umatilla County): 3 results from 3 wells, median 203.0 pCi/L, range 110.0-450.0 pCi/L; none above any federal threshold
