Common Misinterpretation of Uranium Data in Benton County Water
It is easy to assume that if uranium has been found in groundwater samples taken in Benton County, your household water must have the same uranium levels or pose a safety concern. However, government sampling data only represent measurements from specific wells in the area and do not specifically reflect your well water's condition. Detections show that uranium was measured in a sample, not necessarily that it exceeds any health or safety standard.
Reading the Median and Range of Uranium Concentrations
The U.S. Geological Survey conducted groundwater sampling in Benton County’s 111ALVM aquifer, collecting data from three separate wells between 2011 and 2017. Their measurements showed uranium detected in all four sample results, ranging from 0.037 to 0.973 micrograms per liter (ug/L), with a median concentration of 0.3355 ug/L. These figures represent what was found in that area's sampled wells, not any specific household’s water. The sample depths varied from 18 to 80 feet underground.
What the Measured Uranium Range Means in Relation to Federal Standards
While uranium was detected in all samples, none of the recorded values exceeded federal thresholds for uranium in drinking water. This means the uranium levels found in the Benton County aquifer samples do not violate any safety regulations. However, the presence of uranium—even below limits—can influence decisions on whether treatment is desired for aesthetic or precautionary reasons.
Understanding Key Terms: 'Detected,' 'Median,' and 'Range'
In this context 'detected' means a measurable amount was found using laboratory instruments. It does not indicate a regulatory violation or health hazard by itself. The 'median' is the middle value in the set of results, providing a central tendency that might be typical for this area’s sampled wells. The 'range' shows the lowest and highest measured uranium concentrations among the sampled wells during the specified period.
Information to Note Before Seeking Treatment Guidance
Before considering treatment options, document the results of your own water tests since area data cannot substitute for well-specific analysis. Relevant information includes:
- Exact uranium concentration from your water test results
- Depth and type of your water source (well depth, aquifer, or surface)
- Any other water quality tests completed
- Flow rates and household water usage patterns
Having this detailed information enables precise recommendations for water treatment needs.
How Sampling Depth and Well Characteristics Affect Uranium Expectations
The sampled Benton County wells ranged between 18 and 80 feet deep, which affects uranium concentration measurements. Deeper wells might encounter different mineral interactions and water chemistry, potentially leading to varied uranium levels. Sampling from public systems or shallow wells may show differing results. Knowing your well’s depth and aquifer source helps set realistic expectations for your water quality.
Routine Maintenance for the Documented Treatment Technology
The Fleck Uranium & Radium System, designed for residential use, addresses uranium and radium by reducing their concentrations through a filtration process. Built with a 32,000-grain capacity, the system is engineered to operate over extended periods before maintenance is needed. Routine attention involves following the manufacturer’s recommendations for system regeneration and monitoring of water quality at intervals suited to your water usage and uranium detection levels. The system ships ready to configure for your household.
When deciding which class of treatment you need, base your choice on your own water’s uranium concentration relative to local measurements and federal standards. Testing your well water and comparing the results with the Benton County aquifer data can guide you toward the appropriate treatment level. The Fleck Uranium & Radium System offers a proven solution aligned with these needs.

Source: USGS groundwater sampling. Sampled 2017-09-25. 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 Uranium in the 111ALVM aquifer (Benton County): 4 results from 3 wells, median 0.3355 ug/L, range 0.037-0.973 ug/L; none above any federal threshold
