Union Parish's groundwater from aquifer 124SPRT feeds many residential wells, extending hundreds of feet below the surface. Water reaching household taps passes through deep wells that tap into this aquifer, drawing water that may contain naturally occurring radon-222, a radioactive gas dissolved from underground rock formations.
If you are a commercial or industrial water user in Union Parish
Bigger operations, such as businesses or industrial sites, must consider radon not only in their water supply but also in potential occupational air exposures from water use. They often require more frequent and detailed radon testing at multiple points and may face stricter regulatory limits for continuous emissions or discharge. Household assessments and treatment approaches generally do not cover these additional commercial risk factors.
If your well taps to different depths in aquifer 124SPRT
The USGS gathered radon-222 results in Union Parish from wells ranging 350 to 725 feet deep. Radon concentrations can vary by depth because radon enters water from rock decay in the surrounding geology and can accumulate more at some levels. Median radon levels in area wells were 96.0 pCi/L, with a range from 69.0 to 300.0 pCi/L. These samples were not from your well. To know your water, a specific laboratory test on your well water is essential. Testing your exact source water is the only way to confirm your home's radon level and help tailor treatment if needed.
If your existing radon water treatment equipment has failed
WaterSoftenerPlus offers the C-Series Radon in Water Filter, a system designed to reduce radon concentration in household water supplies. This system uses filtration technology configured to address radon dissolved in water by providing an effective barrier that prevents radon release into the home's water lines. The C-Series ships ready to configure and is intended to restore your home's water treatment capacity reliably after a failure. Using a properly configured system can help maintain water quality and reduce potential radon exposure linked to water use.
If you consider radon aesthetic secondary standards versus health-based limits
Radon-222 is measured with federal guidelines to manage health-based cancer risk from waterborne radon exposure, but there are also secondary aesthetic standards in some regions addressing taste, odor, or staining. It is important to recognize that exceeding an aesthetic guideline does not imply a health risk or violation. In Union Parish's aquifer 124SPRT sampling, no results exceeded federal health-based thresholds. Radon detections indicate presence, not necessarily a health concern, and treatment decisions should focus on confirmed test results from your water, not area-wide ranges.
If you plan to seek advice for radon treatment solutions
Before contacting any water treatment professional or vendor, record your well depth, the date and source of any recent laboratory radon test results on your water, and any history of water treatment system performance issues or failures. Having this information allows for specific inquiry and recommendations tailored to your household's water profile rather than broad regional data alone.
What the USGS data for Union Parish's aquifer 124SPRT does not tell you
The radon-222 values reported by USGS come from a small set of deep wells sampled between June and September 2012. These figures reflect conditions within the local aquifer but do not represent your home's specific well water. No detection is a violation or proves unsafety, and no median or range value applies directly to your water without testing. Area data should guide awareness rather than conclusions about your individual water quality or treatment needs.

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
