Government sampling of groundwater wells in Marshall County, Mississippi, specifically from aquifer 124TLLT, shows Uranium detected in four of six samples, with concentrations ranging from 0.007 to 0.041 micrograms per liter (µg/L) over sampling dates spanning March 2011 to June 2022. No measurement exceeded federal standards. These results derive from wells 33 to 38 feet deep and represent general aquifer conditions, not any individual household well.
If you want to compare Marshall County’s Uranium levels with a neighboring county
Comparisons with nearby counties should respect that each aquifer system has unique geologic and hydrologic characteristics influencing Uranium presence. Differences in sampling years and well depths affect observed ranges. Using Marshall County’s median of 0.0215 µg/L and maximum of 0.041 µg/L as a reference, neighboring records might be higher or lower but are not automatically predictors for your water quality. Avoid assuming uniform conditions beyond the sampled wells.
If you consider aesthetic secondary standards versus federal health-based limits for Uranium
Aesthetic secondary standards focus on factors like taste or staining, but Uranium regulation is health-based, reflecting long-term exposure risks. The federal maximum contaminant level (MCL) for Uranium is 30 µg/L, far above the area’s highest detected concentration. Thus, the detected values in Marshall County do not raise aesthetic or health concerns by themselves. Treatment decisions should prioritize health-based thresholds and personal risk tolerance.
If you seek to understand seasonal or multi-year variation shown in the area’s Uranium data
The samples collected over more than a decade reveal some variation but consistently remain well below regulatory limits. This suggests natural fluctuations possibly due to rainfall, groundwater recharge, or geochemical changes within the aquifer. However, no clear trend toward increase or decrease is evident. Such data encourages periodic water testing rather than reliance on a single historical result when making treatment choices.
If you want to differentiate public system records from private well water testing results
The USGS data covers private wells sampled for research, not public water systems serving neighborhoods or municipalities. Public systems are regularly monitored and must meet regulatory standards, often with treatment in place. Private well owners bear responsibility for their water quality, and localized testing of your own well water is essential to determine actual Uranium levels before selecting treatment equipment.
If you are curious how Uranium enters groundwater or distribution systems in Marshall County
Uranium in this region’s groundwater typically derives from natural erosion of Uranium-containing minerals in soil and bedrock. Its mobility depends on geochemical conditions such as pH and oxidation-reduction potential. Unlike surface contamination, this natural presence is stable but can vary with aquifer depth and flow paths. When water is drawn from these aquifers, Uranium may be present at low concentrations as shown by the area data.
If you want to understand what the measured Uranium range means against federal standards and what it does not mean
The highest Uranium concentration measured in Marshall County wells—0.041 µg/L—is well below the federal MCL of 30 µg/L. This indicates no regulatory exceedance in the sampled area but does not guarantee your household well water matches these low levels. Detection alone does not imply health risk or mandatory treatment. Confirming your specific water quality through testing is necessary before choosing a treatment approach.
In summary, the Marshall County, MS Uranium data provides a low-level regional background profile from aquifer 124TLLT, without any federal threshold exceedance. Do not conclude your household water matches these figures without direct testing. If Uranium is confirmed in your water at levels of concern, the Pentair Uranium & Radium System is documented to reduce Uranium and Radium effectively. This system ships ready to configure, with a capacity of 32,000 grains, and offers a solution for households needing treatment following confirmed water quality results.
