If You Wonder What Regional Measurements Indicate About Your Water

Government sampling of groundwater in the aquifer labeled 000OVBD in Grant County shows uranium was detected in all 30 samples collected from 14 wells between 2010 and 2025. These wells ranged in depth from 15 to 153 feet. While uranium presence is consistent, none of the samples recorded exceeded federal thresholds that guide safe drinking water standards. However, such area-wide data cannot determine the uranium-radium levels in your own household water supply. Your well conditions may vary due to depth, local geology, and well construction. To know your water’s specific status, testing your individual well water through an accredited laboratory is necessary.

If You Consider What Happens When Uranium-Radium Is Not Addressed Over Time

Uranium and radium are naturally occurring elements that can dissolve into groundwater from mineral deposits. Extended exposure to elevated levels of uranium or radium in drinking water, even below federal limits, may make some households want to reduce these constituents due to their radioactive nature. Without any treatment, traces of uranium-radium remain in tap water, which some may find concerning and wish to manage to maintain long-term water quality and peace of mind.

If You Assess the Difference After Water Treated by the Fleck Uranium & Radium System

The Fleck Uranium & Radium System, with a grain capacity of 32,000, is designed to reduce uranium and radium content from residential water sources. Once configured, water treated by this system is expected to contain significantly lower traces of these elements. This improvement often results in water that meets or is well below all relevant federal standards for uranium and radium concentrations. It addresses the concern of naturally occurring radioactive elements without altering other desirable water characteristics.

If You Are Choosing How to Identify Your Specific Water Quality Issue

Start by collecting your private well water sample for laboratory analysis focusing on uranium and radium measurements. Before this, simple visual or taste checks will not identify these elements, as they are colorless and tasteless. Compare your laboratory results to federal standards to evaluate if treatment is advisable. Avoid assumptions based on regional data alone, and do not interpret detection as a violation or hazard without test results specific to your water.

If You Wonder What Terms Like 'Detected,' 'Median,' and 'Range' Signify in the USGS Data

The term "detected" means uranium was measurable in every sampled instance in the region’s aquifer. The "median" value of 10.02 micrograms per liter represents the middle concentration among all samples—half the measurements fell below this figure and half above. The "range," spanning 0.635 to 47.9 micrograms per liter, shows the lowest and highest measured uranium concentrations in the wells tested. None of these measurements exceed federal regulatory limits, indicating the regional groundwater meets national safety criteria.

If You Seek to Understand How Uranium and Radium Enter Groundwater Here

Natural geological formations containing uranium and radium minerals release these elements into groundwater through rock and soil interactions. In Grant County’s aquifer 000OVBD, this natural leaching process explains the consistent detection across multiple wells and depths. Human activity is not the primary source; instead, it reflects the local mineral composition influencing groundwater chemistry over time.

If You Examine How Uranium Levels Change Through Time in Grant County Data

The USGS sampling from July 2010 to September 2025 indicates uranium concentrations fluctuate within the recorded range but remain under federal standards. This temporal variability is typical for groundwater systems, influenced by rainfall, aquifer recharge, and well conditions. Monitoring data over years helps establish a regional baseline but does not predict future changes at an individual well without ongoing testing.

For households concerned about uranium and radium in their water, evaluation starts with testing your own water. If treatment is desired, the Fleck Uranium & Radium System ships ready to configure and can reduce uranium and radium effectively, with a grain capacity of 32,000, matching typical residential demand for these constituents.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2025-09-30. 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 000OVBD aquifer (Grant County): 30 results from 14 wells, median 10.02 ug/L, range 0.635-47.9 ug/L; none above any federal threshold
