If your water test report lists Radon-222 in picocuries per liter (pCi/L)
A laboratory test measuring radon in your household water will show a concentration in picocuries per liter (pCi/L), a unit that quantifies the radioactivity of radon gas dissolved in water. The US Geological Survey sampled groundwater from four wells in Union Parish’s 124SPRT aquifer, finding radon concentrations ranging from 69.0 to 300.0 pCi/L with a median of 96.0 pCi/L. All samples detected radon; none was below the reporting limit, and none exceeded federal radon limits for water sources. These results reflect regional conditions but do not reveal the specific concentration in your household's water. Only a direct water test from your own supply can determine your home’s radon level.
If you notice that radon affects water fixtures like showers and taps first
Radon gas can escape from water when it is agitated or heated, which happens most noticeably at fixtures such as showers, faucets, and other appliances using water. When water containing radon flows through these points, some radon transfers into the air, potentially increasing indoor air radon levels. This is why showers and hot water use typically affect occupants first. However, the extent depends on your water’s radon concentration and ventilation conditions in your home.
If you want to understand how the Pentair Radon in Water Filter removes radon
The Pentair Radon in Water Filter uses a technology designed specifically to reduce radon dissolved in water. It passes water through a treatment medium that encourages radon to separate from the water, lowering radon levels before water reaches household fixtures. This process helps reduce radon both in water and the resulting radon released into indoor air through water use. The system ships ready to configure, so it can be connected to your water line with your preferred plumbing approach.
If you are wondering about additional questions for commercial or industrial water users compared to households
Commercial and industrial operations face higher water volumes and different usage patterns than residences. They often ask about the system’s capacity to handle peak water demand, compliance with workplace safety standards, and integration with larger-scale water treatment setups. Households typically focus on daily water use and indoor air quality effects, while commercial queries include operational throughput and regulatory reporting, which do not apply directly to residential users.
If you want to know how water quality changes at the tap after treatment with the Pentair system
Water treated by the Pentair Radon in Water Filter typically shows significantly reduced radon levels at household faucets and appliances. This means less radon gas is released into indoor air during water use, lowering potential radon exposure from water sources. Treated water remains clear and unchanged in taste and odor, addressing radon without altering other water quality aspects.
If radon in water is left untreated for years, what are the effects?
Long-term exposure to radon in water can contribute to increased radon levels in the home’s air, as radon gas escapes from water during normal use. This can marginally raise indoor radon exposure, which is a recognized inhalation health concern. While radon dissolved in water is just one source of radon exposure, untreated water may add to the cumulative radon concentration inside your home over time. Regular testing of both water and indoor air can help monitor this.
If plumbing material or age affects radon levels independent of source water
Plumbing materials and age do not generate radon, as radon originates underground from natural decay of uranium in soil and rock. However, plumbing configurations and materials may influence how radon gas is released or trapped during water use. Older or deteriorated plumbing might affect gas exchange or water flow, but they do not increase radon concentration in source water. Understanding your home’s plumbing can inform how radon from water behaves once inside your household system.
Given the median radon levels found in Union Parish’s 124SPRT aquifer wells, many households may want to measure radon in their own water supply to understand their specific exposure. The Pentair Radon in Water Filter provides a direct solution by reducing radon levels in water based on household demand, helping manage radon release during everyday water use.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2012-09-27. 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 124SPRT aquifer (Union Parish): 4 results from 4 wells, median 96.0 pCi/L, range 69.0-300.0 pCi/L; none above any federal threshold
