If you're wondering about uranium and radium in your water in Oakland County, MI, the first step is understanding what regional data shows and what it means for your household. Sampling by the U.S. Geological Survey in this area’s aquifer (112OTSH) reveals alpha particle activity levels that do not exceed federal health-based thresholds, but your own water’s condition depends on specific testing.
If You Rely on Public-System Water Records Versus Private-Well Testing
The U.S. Geological Survey performed groundwater sampling in Oakland County across 15 wells between 11 and 49 feet deep during 2016. They measured alpha particle activity, which indicates the presence of uranium and radium decay products. The median value was 2.45 pCi/L with results ranging from -0.6 to 7.0 pCi/L, and all samples were below federal action levels.
Public-system records describe broader area conditions but do not substitute for testing your home’s well or water source. Private wells can vary locally due to geology, depth, and water pathway. Only a dedicated alpha particle or uranium-radium test on your water confirms your household’s actual exposure.
If You Manage Water for a Large Household, Second Home, or Seasonal Residence
Household size and usage patterns influence water treatment needs. Larger families or homes with higher daily water demand may require treatment systems with a greater capacity to handle uranium and radium effectively over time. Seasonal properties might experience different groundwater chemistry due to changes in water table or usage patterns between seasons.
Such variations mean treatment decisions also depend on how frequently water is used and stored. The Pentair Uranium & Radium System, rated for 32,000 grain capacity, ships ready to configure for homes with these specific demands.
If You Want to Understand How Uranium and Radium Enter Groundwater Here
In Oakland County’s aquifer 112OTSH, uranium and radium naturally occur in underground rock formations. Alpha particle activity detected in the sampled wells originates from radioactive decay of these elements. Groundwater flows through mineral-rich layers, dissolving small amounts over time. This natural process results in measurable alpha radiation but without necessarily implying unsafe levels.
Human activities have limited impact on uranium-radium levels here compared to this natural geologic influence.
If You Confuse Aesthetic Water Quality Measures with Health-Based Limits for Uranium-Radium
Secondary standards for water aesthetics relate to taste, odor, color, or staining and do not apply directly to uranium or radium. The federal limits for uranium and radium are health-based and focus on the potential radiological effect of alpha particles. The sampled wells in Oakland County showed no exceedances of these federal health benchmarks.
Understanding this distinction helps prevent misinterpretation of measurements that detect uranium or radium below action levels as a safety concern.
If You Are Unsure Whether Uranium-Radium Is the Actual Issue Compared to Other Water Constituents
Other water quality problems can cause staining, taste, or corrosion but do not involve radioactive decay products. Uranium-radium specifically relates to alpha particle emissions in water from natural deposits. Testing focused on these alpha emitters differentiates this concern from more common but unrelated issues.
The single most definitive step is to order a laboratory test for alpha particles or uranium-radium on your household water source. A result indicating alpha activity below federal thresholds would confirm that uranium and radium levels fall within recognized safety margins. If treatment is desired, the Pentair Uranium & Radium System provides a documented solution designed for typical residential needs in this region.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-27. 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 112OTSH aquifer (Oakland County): 30 results from 15 wells, median 2.45 pCi/L, range -0.6-7.0 pCi/L; none above any federal threshold
