How do the median and range values from Clinton County's aquifer 111ALVM help me understand my water?
The U.S. Geological Survey has monitored groundwater in Clinton County's aquifer 111ALVM, where wells between 22 and 65 feet deep were tested from September to October 2017. They measured alpha particle activity, which indicates uranium and radium presence. The median value found was 1.35 picocuries per liter (pCi/L), with results ranging from 0.4 to 3.3 pCi/L across six samples from three wells. These values offer a regional perspective, not your household's specific situation. They represent typical levels found in the sampled wells, providing context if you are dealing with uranium or radium concerns after equipment failure.
What do 'detected,' 'median,' and 'range' mean in this sampling record?
'Detected' means the instrument measured alpha particle activity in every sample. None of the results fell below the reporting limit, so every sample had a quantifiable level. The 'median' is the middle value separating higher and lower measurements—in this case, 1.35 pCi/L indicates half the results measured above and half below this number. The 'range' from 0.4 to 3.3 pCi/L shows the spread between the lowest and highest detected values. These terms describe how often and at what concentration uranium and radium appeared in area wells but do not imply any single well or household water matches these figures exactly.
How is uranium-radium contamination different from other common water quality issues?
Uranium and radium are naturally occurring radioactive elements that emit alpha particles. Their presence is distinct from common problems like iron staining or hardness. Unlike aesthetic concerns that influence taste or color, uranium and radium have regulatory levels established for drinking water as part of federal standards, although no sample in this area exceeded those thresholds. This problem is unique because it involves radioactivity measured in picocuries per liter, requiring specific testing methods and treatment approaches different than for typical mineral or particulate concerns.
How does the Fleck Uranium & Radium System reduce uranium and radium in household water?
The Fleck Uranium & Radium System is designed to address uranium and radium removal efficiently. It uses a technology configured to reduce these radioactive elements by filtering and exchanging contaminants, supporting capacity up to 32,000 grains. This system ships ready to configure for home use and can restore safe and aesthetic water quality after your previous equipment no longer functions properly. Its documented method targets the alpha particle emitters associated with uranium and radium, helping homeowners regain control over their water's quality with a reliable treatment solution.
What information should I have ready before seeking treatment advice?
Before contacting any treatment provider or evaluating options, document your water source characteristics and recent test results if available. Note the following:
- Location: Clinton County, IA
- Aquifer: 111ALVM
- Depth of water source (if known)
- Details on equipment failure and previous treatment methods
- Any recent water testing results, especially for uranium, radium, or alpha particle activity
- Household water usage patterns and size
Having these details lets you communicate clearly and receive recommendations tailored to your unique situation.
What should I not assume about my well water based on this area data?
The regional data from Clinton County and aquifer 111ALVM offers useful context but cannot replace testing of your own household water. Detection of uranium and radium in area wells does not indicate a violation or unsafe condition by itself. Similarly, these results do not mean your water contains the same levels or that a health risk exists without further analysis. Only a direct test of your well or tap water can determine individual concentrations and whether treatment is necessary. It is important not to conclude any exceedance or safety issue solely from area sampling records.

Source: USGS groundwater sampling. Sampled 2017-10-25. 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 Alpha particle in the 111ALVM aquifer (Clinton County): 6 results from 3 wells, median 1.35 pCi/L, range 0.4-3.3 pCi/L; none above any federal threshold
