Radon in Miller County Water: Understanding Local Radon Levels from Aquifer 124SPRT
Understanding Radon Sampling Data in Miller County
Detected Radon in All Sampled Wells
The U.S. Geological Survey sampled three wells accessing aquifer 124SPRT in Miller County, finding radon-222 present in each one during the 2012 collection period.
Median Concentration Indicates Typical Range
The median radon value was 55.0 picocuries per liter (pCi/L), with individual samples ranging from 49.0 up to 370.0 pCi/L across wells 85 to 150 feet deep.
Sampling Reflects Regional Conditions, Not Individual Wells
These numbers describe the area aquifer overall, not any specific household’s water. Testing your own well is necessary to determine your water’s radon level.
Changes in Water Quality After Using a Radon Filter
Removal of Radon Gas from Water Supply
Once water passes through the Pentair Radon in Water Filter, radon concentrations can be significantly reduced, helping lower radon-related concerns at the tap.
Preserving Water’s Usability and Taste
This filtration method targets radon specifically without substantially altering other water qualities important for household use.
Operation Ready to Use Without Additional Setup
The system ships ready to configure, designed for integration with residential water lines without complex modifications.
Comparing Miller County’s Radon Levels to Neighbouring Areas
Similar Testing Approaches in Nearby Counties
Sampling in adjacent counties follows comparable methods and depths, allowing for contextual comparisons but not direct conclusions about differences at your home.
Variation in Radon Concentrations Across Regions
Radon levels may vary widely due to geology and well depth; Miller County’s median and range provide a regional overview rather than a benchmark for individual wells.
Potential Outcomes if Radon Is Left Unaddressed in Water
Long-Term Exposure Considerations
Radon dissolved in water can release into indoor air during household use, contributing to overall radon exposure over time.
Importance of Monitoring and Addressing Elevated Levels
Without testing and treatment where needed, radon presence in water may add to indoor radon burdens, influencing air quality and potential health considerations.
How Radon Enters Groundwater in Miller County
Geological Origins of Radon
Radon forms naturally from the decay of uranium in soil and rock, migrating into groundwater through fractures and porous layers in the aquifer.
Influence of Well Depth and Construction
Wells accessing the 124SPRT aquifer between 85 and 150 feet tap water that has traveled through radon-bearing formations typical in this region.
Surface Water and Distribution Systems Are Separate Concerns
Radon levels in groundwater differ from surface or treated municipal water sources, so local water source type affects radon presence.
Final Checklist Item
After measuring your household water’s demand, consider the Pentair Radon in Water Filter as a targeted solution to reduce radon levels reflective of local ranges documented in Miller County's aquifer 124SPRT.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2012-10-29. 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 124SPRT aquifer (Miller County): 3 results from 3 wells, median 55.0 pCi/L, range 49.0-370.0 pCi/L; none above any federal threshold
