What a Uranium Laboratory Test Report Shows
When testing for uranium in water, laboratory reports typically list the concentration in micrograms per liter (µg/L). For Nemaha County’s aquifer 112DRFT, uranium measurements from government sampling range from 0.567 to 36.9 µg/L with a median of 7.18 µg/L. These figures represent values detected in 15 samples taken from 14 different wells between August 3 and August 25, 2011. Importantly, none of these reported results exceed any federal regulatory thresholds.
How Uranium Enters Groundwater in Nemaha County
In Nemaha County, uranium naturally occurs in the subsurface geology and enters groundwater primarily through leaching from minerals in soil and rock formations. Aquifer 112DRFT, the source for local well water, draws from depths between 18 and 69 feet where uranium can dissolve into groundwater. This process is influenced by regional geochemical conditions including natural mineral content and groundwater movement.
What the Measured Range Means Against Federal Standards—and What It Does Not Mean
The uranium concentrations detected in Nemaha County wells all fall below any federal limits, which are set to protect public health. Detecting uranium at these levels does not indicate a violation or necessarily a safety concern. The concentration range simply documents the presence and variability of uranium within the aquifer sampled. It does not predict the concentration in any individual water source without specific testing of that water.
Sample Size, Depth, and Interpretation Considerations
The dataset includes 15 uranium measurements from 14 wells. This sampling size provides useful insights into the general range and median concentration of uranium in the aquifer but cannot represent every well’s condition precisely. Wells sampled were relatively shallow (18 to 69 feet deep), which is typical for residential water use in the area. More samples would increase confidence in the data’s representativeness, but the current scope is sufficient to understand the aquifer's uranium levels broadly.
The Role of Plumbing Material and Age on Uranium Levels
Uranium concentration in tap water primarily reflects its source—the groundwater drawn from the aquifer. Plumbing materials and the age of pipes do not generate or increase uranium levels. However, plumbing can influence other water quality aspects such as corrosion or secondary contaminants but does not affect uranium content. Thus, uranium test results should be linked to source water, not household plumbing.
Household Symptoms Commonly Attributed to Uranium Do Not Indicate Water Quality Alone
Symptoms sometimes linked to uranium exposure are not visibly detectable in water quality or by senses. There are no taste, color, or odor changes indicating uranium levels. Therefore, household symptoms alone cannot diagnose uranium presence or concentration. Confirming uranium contamination requires certified laboratory analysis of the well water.
Judging Treatment Capacity Based on Daily Household Water Use
Treatment systems for uranium must match daily water demand to be effective. Evaluating household daily consumption against system capacity ensures continuous treatment without performance loss. For a residential setting requiring uranium removal, a system with a grain capacity of 32,000, such as the Fleck Uranium & Radium System, is designed to handle uranium levels within documented regional ranges while providing sufficient service for typical household volumes.
Choosing the appropriate water treatment equipment involves verifying your own water’s uranium level through professional testing and comparing that demand to system specifications. The Fleck Uranium & Radium System ships ready to configure and offers a documented solution for uranium and radium reduction suitable for Nemaha County’s groundwater conditions.

Source: USGS groundwater sampling. Sampled 2011-08-25. 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.
