How Uranium and Radium Enter Groundwater in Umatilla County
In Umatilla County, groundwater flows through aquifer N600CMBPLV, a deep geological formation from which residents draw water. Naturally occurring uranium and radium are elements found in some rock types underground. Over time, these elements can dissolve and enter the groundwater as alpha particle radiation is detectable in sampled wells. It is common for uranium and radium to be present at low levels in natural waters due to local geology rather than any pollution source.
Interpreting Certified Laboratory Test Reports for Uranium and Radium
Certified laboratory analyses for uranium and radium typically measure alpha particle activity, reported in picocuries per liter (pCi/L). For Umatilla County’s aquifer N600CMBPLV, government groundwater sampling recorded alpha activity ranging between -0.8 and 1.2 pCi/L across six sample results from three separate wells, taken during mid-2016. A median value of -0.1 pCi/L indicates most measurements were below detection thresholds or very low. None of these results exceeded any federal regulatory thresholds or safety standards. Remember, these values represent regional aquifer conditions in wells drilled 502 to 1116 feet deep, not specific household water.
What Details to Gather Before Asking for Treatment Advice
If water treatment equipment has failed, it is critical for a household to first obtain a current, certified laboratory test report of their own water supply. This report should specify the measurement of alpha particle activity or uranium/radium content. Note well depth, water source type (private well or municipal), and any recent changes in water taste, color, or texture. Document existing equipment specifications and any maintenance or failure history. Having this information on hand allows for informed discussions regarding suitable options.
Household Symptoms Linked and Not Linked to Uranium and Radium Presence
Direct symptoms from uranium or radium in water are generally not immediately apparent at fixtures. Unlike iron staining or sulfur odors, uranium and radium do not usually cause visible or sensory changes in water. Appliances and plumbing typically show no rapid effects from these constituents. However, these elements can contribute to long-term concerns related to radiation exposure if present at elevated levels over extended periods.
Consequences of Leaving Uranium and Radium Untreated Over Years
If uranium and radium levels remain elevated without treatment, potential health risks related to chronic exposure to alpha particle radiation may increase. Long-term consumption of water with significant amounts of these elements can be a concern but requires precise testing to evaluate individual risk. Treatment approaches reduce these constituents effectively. Since untreated water does not always show immediate signs, relying on testing and proper water treatment is a prudent step for households with equipment issues.
What Not to Conclude from Regional Sampling Data
The median and range of alpha particle activity reported by U.S. Geological Survey for Umatilla County’s aquifer N600CMBPLV do not define the uranium-radium content of any single household’s water. Detected values in local wells are not violations or statements of unsafe conditions. They reflect regional natural background levels and are meant to provide context, not individual water safety evaluations. Households should not assume their water matches these figures but use them as a reference point while obtaining their own water tests.
For homes faced with failed current equipment designed to remove uranium and radium, the C-Series Uranium & Radium System ships ready to configure and offers a documented capacity of 32,000 grains for reducing these constituents effectively when properly applied after evaluating household-specific water data.

Source: USGS groundwater sampling. Sampled 2016-08-10. 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.
