Government groundwater sampling in Ouachita County, Arkansas, aquifer 124SPRT, found radon-222 detected in all five samples taken from four wells between 2012 and 2014. These results showed radon concentrations ranging from 40.0 to 108.0 pCi/L, with a median of 71.0 pCi/L. None of these values exceed any federal standard for radon in drinking water. This data reflects measurements from wells 135 to 375 feet deep and does not represent any individual well’s water quality.
Stepwise Approach to Determining Your Household’s Radon Treatment Needs
Begin by reviewing any recent radon testing reports you may have from your well water, if available. If no recent test exists, consider a certified laboratory analysis of radon-222 in your water as the definitive step. Direct measurement is necessary because regional data cannot substitute for your specific water conditions.
Before laboratory testing, evaluate any clues from your water system such as radon-related odor or discoloration, although such signs are not definitive for radon presence. Additionally, consult state or local health resources for any guidance on radon levels common in nearby households sharing the same aquifer.
How Radon Reaches Groundwater in Ouachita County’s 124SPRT Aquifer
Radon-222 naturally originates from the radioactive decay of uranium in rocks and soils. In the Ouachita County aquifer, radon enters groundwater by dissolving into water as it moves through uranium-containing materials underground. The depth and geology of wells influence radon levels, which explains variability among sampled wells.
Comparing Ouachita County to Nearby Counties: Using Caution
While neighboring counties may report different radon levels, such comparisons require careful interpretation. Differences in geology, aquifer characteristics, and sampling methods mean this area’s median result of 71.0 pCi/L should not be directly equated with results from other regions. Use neighboring data only as a general reference, not as a substitute for local testing.
Sample Size and What It Means for Interpreting Radon Data
This dataset includes five samples from four distinct wells, a modest collection to indicate regional radon presence. Though limited in number, the consistently detected radon confirms it is measurable within this aquifer. However, the small sample count means individual wells can vary significantly from the range observed.
Information You Should Gather Before Consulting on Treatment
- Well depth and construction details
- Results from any recent radon testing in your water
- Water usage patterns in your household
- Any history of water quality issues related to radioactivity
Having this information ready enables focused advice on whether a radon water treatment system is appropriate and which type matches your household needs.
Radon Versus Other Water Quality Concerns
Radon is distinct from other groundwater issues such as bacterial contamination or mineral-related aesthetic problems. It is a radioactive gas dissolved in water, not a sediment or biological contaminant. Its presence and treatment involve different considerations, so don’t confuse radon with turbidity or taste-related concerns.
In summary, government data documents detectable radon-222 in Ouachita County aquifer 124SPRT wells at levels below federal action thresholds. This regional information supplies a context but not a replacement for testing your own water. The Autotrol Radon in Water Filter system ships ready to configure and can address radon removal once testing justifies treatment.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-07-24. 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.
