This week, your household needs to decide which radon water treatment equipment class best meets your daily water demand.
How do public-system radon water records differ from private well testing?
Government records, such as the U.S. Geological Survey (USGS) groundwater sampling in Box Elder County’s 100VLFL aquifer, provide area-wide data from specific wells but do not reveal the radon levels of your individual well or tap water. The USGS sampled three wells between August 13 and 20, 2013, detecting radon-222 in all three with a median concentration of 750.0 pCi/L and a range from 290.0 to 1090.0 pCi/L. Each well was between 422 and 515 feet deep.
These figures reflect conditions in the sampled aquifer area and cannot substitute for testing of your own water supply. To know your household’s radon concentration precisely, testing your well or tap water directly is necessary.
What distinguishes radon in water from other, commonly confused concerns?
Radon-222 is a naturally occurring radioactive gas that can dissolve into groundwater. Unlike contaminants that affect taste or stain fixtures, radon is a radioactive element whose presence in water primarily poses an inhalation risk when released into air during water use. This contrasts with minerals or chemicals that cause discoloration or taste issues. Radon’s detection in water does not mean the water is unsafe to drink per federal standards; none of the USGS results exceeded federal thresholds for radon in water in this area.
How should I judge treatment capacity against my household’s water demand?
Choosing the right radon removal equipment depends on your typical daily water use. Treatment capacity should meet or exceed this demand to ensure effective radon reduction without interrupting supply. Calculate your household’s average water consumption from all sources—kitchen, bath, laundry, and other uses—and look for a system designed to handle that volume efficiently.
What can seasonal or multi-year variation tell me about radon levels here?
The USGS sampling dates in mid-August 2013 provide a snapshot rather than continuous monitoring. While radon levels can vary seasonally and over multiple years due to factors like groundwater flow and temperature changes, these three well results set a baseline for Box Elder County’s 100VLFL aquifer. Without additional data points, caution is warranted in assuming stable or fluctuating radon concentrations over time.
What does the measured radon range mean compared to federal standards?
The USGS recorded radon levels from 290.0 to 1090.0 pCi/L, with no results exceeding federal standards for radon in water. Detection here means radon was measurable, not that levels are unsafe or in violation. These figures inform you of the potential presence and concentration range you might expect but do not diagnose your water. Testing your household supply remains the only way to confirm radon levels in your water.
For households seeking to address radon based on their measured demand, the Pentair Radon in Water Filter ships ready to configure and offers a proven technology to reduce radon in water effectively. Selecting a system sized appropriately to your daily water use will ensure optimal performance and peace of mind.
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
