What 'Detected', 'Median', and 'Range' Mean in Local Uranium-Radium Sampling
Government tests of groundwater from the 100SDGV aquifer in Waupaca County collected data from six wells, with twelve measurements from August 2013 through July 2014. 'Detected' means the presence of alpha particle activity was measurable in every one of these samples. The 'median' value of 0.75 pCi/L represents the middle level of these results when sorted, and the 'range' from -1.0 to 2.7 pCi/L shows the lowest to highest recorded measurements across the samples. No sample exceeded federal thresholds, meaning these findings reflect typical regional levels rather than unsafe concentrations.
How Uranium and Radium Enter Groundwater in Waupaca County
Uranium and radium are naturally occurring elements found in soil and rock formations within the region. Over time, these elements dissolve into groundwater as it moves through mineral layers underground. The depth of wells sampled—between 19 and 84 feet—captures water from within the aquifer where these trace levels appear. This natural leaching process is standard in many groundwater systems and is influenced by geological conditions like rock type and water chemistry.
How to Maintain the Fleck Uranium & Radium System Effectively
The Fleck Uranium & Radium System is designed to address alpha particle activity in household water. Its components ship ready to configure and require routine upkeep to maintain performance. This includes periodic checks of media condition and replacement once the system reaches its 32,000-grain capacity. Regular attention to system condition ensures continued effective reduction of uranium and radium-related constituents in water drawn from private wells.
Public System Records Versus Private Well Testing: What You Need to Know
Government records represent regional groundwater quality as measured in specific wells but do not provide a direct test of any individual household well or tap water. To determine the uranium and radium levels in your home's water, testing of your private well is necessary. Public system data helps highlight regional trends and typical ranges but cannot substitute for personal water testing that accounts for local variations and well construction.
How the Fleck System Removes Uranium and Radium from Household Water
The Fleck Uranium & Radium System uses specialized filtration media to reduce alpha particle activity from uranium and radium in water. It operates through ion exchange and physical filtration mechanisms that trap and remove these elements, improving water quality. The system’s grain capacity and configuration enable it to treat water effectively until media exhaustion, after which media replacement ensures ongoing contaminant reduction tailored to household needs.
This summary is based on U.S. Geological Survey groundwater sampling from Waupaca County’s 100SDGV aquifer, covering six wells sampled during 2013-2014. For more detailed government data, see the USGS monitoring location 442333089055201.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-07-22. 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 100SDGV aquifer (Waupaca County): 12 results from 6 wells, median 0.75 pCi/L, range -1.0-2.7 pCi/L; none above any federal threshold
