What is the typical range of radon in water in Box Elder County, UT? USGS groundwater samples of aquifer 100VLFL in Box Elder County taken in August 2013 show radon-222 detected in all three wells sampled. Concentrations ranged from 290 to 1090 pCi/L, with a median of 750 pCi/L. These samples come from wells 422 to 515 feet deep. This provides an area-level picture, not a direct measurement of your household water, especially if your equipment has failed and you want reliable data.
Radon levels in Box Elder County show variation across sample dates and wells
Though all samples were collected in a narrow date range of August 2013, differences between wells highlight natural variability within the aquifer. This variability may come from differences in well depth, geology, or water flow characteristics. The range of 290 to 1090 pCi/L over these three samples indicates radon concentration in groundwater here can fluctuate, even within a short timeframe and localized area.
Certified lab tests for radon in water provide a precise concentration reading to guide your response
If you want to understand radon levels in your household water, submitting your well water for certified laboratory analysis is essential. Such tests report the radon concentration in picoCuries per liter (pCi/L), a standard measure of radioactivity. This exact figure is necessary because local area data cannot determine your specific water’s radon content. These test results will guide any necessary treatment decisions.
Well depth and source type affect what radon levels might be expected
The USGS sample wells in Box Elder County were 422 to 515 feet deep, typical for large-scale aquifer testing. Radon concentrations can vary with well depth since radon is produced in rocks and soils and dissolves into groundwater. Shallow wells or surface water sources may have different radon profiles than deep wells, so understanding your own well’s characteristics helps interpret lab results and treatment needs.
Public system water records and private well testing serve different purposes in radon assessment
Public water systems often monitor radon to comply with federal regulations, but Box Elder County aquifer sample data do not indicate any exceedance of federal radon thresholds. Private well owners, however, must rely on direct testing of their water because the local system records reflect general aquifer conditions, not individual well levels. Failed household equipment makes this testing especially important to know your water’s specific radon content.
Leaving radon untreated in household water over time should be carefully evaluated
Radon in water can contribute to indoor air radon when water is used for showering, cooking, and cleaning. Although the federal standards aim to manage radon exposure, consistent levels in the range observed in Box Elder County samples suggest that unresolved radon may contribute to cumulative exposure. Without functional radon reduction equipment, evaluating options for treatment is prudent.
After equipment failure, a Pentair Radon in Water Filter system ships ready to configure and is a documented method to reduce radon levels in household water. It is designed to address radon presence by filtering water effectively, supporting safer indoor air quality.
What you should NOT conclude from Box Elder County’s area data alone
Do not assume that the radon concentration in your household water matches the USGS area sample data. These figures represent three deep wells sampled in 2013 and serve only as a regional indication. Area radon detection does not establish any water as unsafe or in violation of federal standards. Precise knowledge requires testing your household water directly, especially when previous treatment equipment is no longer functioning.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-08-20. 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 100VLFL aquifer (Box Elder County): 3 results from 3 wells, median 750.0 pCi/L, range 290.0-1090.0 pCi/L; none above any federal threshold
