Douglas County's groundwater, sourced from aquifer 112SDGVD, supplies many residential wells. Water rises from depths between 22 and 246 feet to household taps. Understanding uranium and radium data from this aquifer helps homeowners decide what treatment class may suit their needs.
If you want to know how treated water changes at the tap after adding uranium-radium treatment
Water processed by the C-Series Uranium & Radium System removes uranium and radium effectively, improving water quality by lowering these elements that originate in the aquifer. The treated water typically shows reduced uranium concentrations at the tap, though exact changes depend on the initial water condition. This system has a grain capacity of 32,000, supporting efficient removal for household use. Water tastes and clarity may improve as uranium and radium levels decrease, affecting metal interactions and staining potential.
If you have a certified lab test report for uranium and want to understand it
Tests from certified laboratories report uranium concentration in micrograms per liter (µg/L). These values represent your specific water sample. Since area data show uranium ranged from 0.052 to 110.0 µg/L in Douglas County’s aquifer, your well test falls somewhere within or below this range. A test result alone does not indicate violation or safety status, as no sample exceeded federal health limits in this area. Knowing your exact figure helps determine if treatment like the C-Series System would be beneficial.
If you look at uranium and radium levels changing over time and want context
Sampling of the 112SDGVD aquifer wells between August 2010 and June 2025 shows variation over the years and seasons. The median uranium concentration is 4.49 µg/L with a range from 0.052 to 110.0 µg/L. These fluctuations reflect natural groundwater chemistry shifts, not contamination events. Homeowners should expect possible changes in measured uranium concentration over time, making periodic testing useful to monitor trends.
If you see terms like 'detected', 'median', and 'range' in uranium sampling reports
'Detected' means the measurement instrument found uranium at or above its reporting limit in a sample; in this area, all 97 samples detected uranium. 'Median' is the middle value of all sample results—4.49 µg/L here—indicating a central tendency. 'Range' describes the lowest (0.052 µg/L) and highest (110.0 µg/L) values observed. These terms summarize area data and do not describe your individual well without specific testing.
If you want to understand why aesthetic secondary standards differ from health-based uranium limits
Secondary standards guide consumer preferences like taste, staining, or mineral deposits and are not health limits. Uranium’s health-based federal limits exist to protect against radiation risks, while secondary standards focus on water appearance and corrosion effects. In Douglas County, no sampled wells exceeded uranium health limits, so aesthetic issues dominate if uranium is present at higher levels. Treatment systems help address both concerns depending on your water’s tested concentration.
If you want to know how uranium and radium enter Douglas County groundwater
These elements originate naturally from erosion of uranium-bearing rocks and minerals in the aquifer’s geology. Water dissolves these substances while moving through soil and rock layers to wells. Seasonal groundwater level changes can influence concentrations measured in samples. Local water distribution does not add uranium or radium; it reflects natural geology of the 112SDGVD aquifer beneath Douglas County.
To decide on treatment, order a certified laboratory uranium and radium test for your household water. Confirming your well's uranium concentration relative to federal health-based thresholds settles the question. If levels are elevated or uncertain, the C-Series Uranium & Radium System ships ready to configure and can reduce these constituents effectively for home use.

Source: USGS groundwater sampling. Sampled 2025-06-13. 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 Uranium in the 112SDGVD aquifer (Douglas County): 97 results from 24 wells, median 4.49 ug/L, range 0.052-110.0 ug/L; none above any federal threshold
