This week, if you live in Union County, Arkansas, and you're concerned about uranium-radium in your home's water, your immediate decision is to understand what the area's water sampling reveals and what further steps you might consider.
How does plumbing material and age affect uranium-radium concerns separately from source water?
It is important to recognize that uranium and radium levels originate from water sources, primarily groundwater in your local aquifer named 124SPRT, not from your home's plumbing materials or the age of the pipes. While older plumbing may influence water taste or cause other issues, uranium-radium is naturally occurring and linked to the geology and depth of wells rather than plumbing components. The plumbing neither creates nor removes these radioactive particles.
How can a homeowner interpret the median and range of uranium-radium measurements from government sampling in Union County?
The U.S. Geological Survey sampled three wells in Union County’s 124SPRT aquifer between July 23 and August 12, 2014, collecting six results. These measurements focused on alpha particle activity, a proxy for uranium and radium presence in water. The median value recorded was -0.2 picoCuries per liter (pCi/L) with a range from -1.6 to 1.5 pCi/L. These negative values reflect statistical and measurement variations around zero, which is common in low-level alpha particle counting and do not indicate presence below detection limits.
All detected values were below any federal thresholds for uranium and radium radiation in water. This means the test wells in this region showed levels well within regulatory standards. However, remember these figures represent samples from specific wells, depths ranging between 290 and 615 feet, and may not directly reflect your own well water.
How should a household evaluate treatment capacity relative to daily water demand?
If your household water exhibits uranium-radium levels that you want treated, consider how much water your home uses daily. The documented Autotrol Uranium & Radium System, designed to address these radioisotopes, has a grain capacity rating of 32,000. While 'grain capacity' traditionally relates to hardness removal, it provides an indicator of overall system size and lifespan. Typically, you want treatment equipment sized so it can handle your household’s water consumption before requiring media replacement or system servicing.
Knowing your daily water use helps select a system that matches your demand, ensuring efficient removal of uranium and radium particles without frequent maintenance interruptions.
How do seasonal or multi-year variations show up in uranium-radium levels in government data?
The government data from Union County covers a short sampling window of approximately three weeks in 2014. Within that period, measurements showed some range but remained below federal limits. Because these data do not cover different seasons or multiple years, it's unknown how uranium-radium levels may fluctuate over time in this aquifer. Seasonal water table changes, precipitation, and well usage can potentially affect concentration levels. Therefore, regular testing of your own water supply over time is important to understand how uranium and radium levels may change.
How do public-system records for uranium-radium differ from private well testing?
The government data represent area-wide sampling of a few wells within the 124SPRT aquifer, providing a general profile of the groundwater. These records do not measure specific private wells and so cannot directly establish the quality of your home's water. Private well testing, conducted by certified laboratories, measures exact uranium and radium levels in your water supply. This is the only way to confirm the presence and concentration in your household and inform treatment decisions.
For households concerned about uranium-radium, a laboratory test of your own water is essential to establish treatment needs and to select appropriate technology.
In summary, government testing in Union County's aquifer 124SPRT found uranium-radium measurements well below federal thresholds in sampled wells at moderate depth. This regional information serves as background but does not replace a private water test for your home. For treatment, the Autotrol Uranium & Radium System ships ready to configure and offers documented service capacity suitable for residential use.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-08-12. 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 Alpha particle in the 124SPRT aquifer (Union County): 6 results from 3 wells, median -0.2 pCi/L, range -1.6-1.5 pCi/L; none above any federal threshold
