Water quality data collected for Oktibbeha County, Mississippi, specifically from wells drawing on aquifer 211GORD, offers insights into radon presence in local groundwater. However, these measurements do not reveal the radon concentration in any individual household water supply.
Radon-222 is a radioactive gas naturally present in soil and rock that can dissolve into groundwater. It is odorless and invisible but can enter your home's water, potentially raising indoor air radon levels when water is used for showering, cooking, or cleaning.
If you want to understand how Oktibbeha County compares with neighboring regions
Three groundwater samples from deep wells (ranging 1368 to 2280 feet) in Oktibbeha County in 2013 showed radon levels from 103 to 140 pCi/L, with a median of 129 pCi/L. These results were consistently below any federal thresholds established for radon in water. When compared with surrounding counties, variations may occur due to geology and well depth, but each county’s data comes from distinct sampling and should not be directly applied to individual household water without testing.
If your residence is larger than average, a second home, or used seasonally
Household size and water use frequency influence exposure to radon in water. Larger homes with more occupants or higher water consumption may have greater indoor air contributions from waterborne radon. Conversely, seasonal or occasional water use can mean less overall radon exposure if the water source is the same. Regardless, only a specific test of your water will reveal the radon level affecting your household.
If you want to distinguish radon issues from related water concerns
Radon is often confused with other water contaminants like iron or sulfur compounds that cause odor or staining. Unlike these, radon is a radioactive gas without taste or odor and cannot be detected through sensory inspection. Its presence is determined only by laboratory testing. Understanding this distinction helps focus testing and treatment decisions correctly.
If you are considering how treated water will differ using the Autotrol Radon in Water Filter
The Autotrol system specifically targets radon in water supplies, reducing the concentration before it reaches taps. After treatment, the water’s radon level is lowered, which can reduce indoor air radon contributions originating from water use. The treated water remains clear, taste-neutral, and unchanged in physical quality aside from the radon reduction.
If you want to know which parts of your household water system are affected first
When radon is present in water, the highest exposure occurs at fixtures releasing water as vapor or aerosols, such as showers, faucets, and humidifiers. These points are where radon gas transfers from water to indoor air most readily. Appliances using water without aerosolizing it, like toilets or washer machines, are less influential on radon air levels.
To confirm your household’s radon water levels and guide treatment needs, the single essential action is to have your well water tested by a certified laboratory for radon concentration. Knowing your specific radon level allows informed decisions about whether to use a treatment such as the Autotrol Radon in Water Filter, which ships ready to configure for your home water system.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-08-29. 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 211GORD aquifer (Oktibbeha County): 3 results from 3 wells, median 129.0 pCi/L, range 103.0-140.0 pCi/L; none above any federal threshold
