What Does a Certified Laboratory Test for Uranium-Radium Report and How Should You Read It?
A certified laboratory test measuring alpha particles—used as an indirect indicator of uranium and radium—reports concentrations in picoCuries per liter (pCi/L). The report details the measured values in your water sample, including detection levels, which simply indicate the presence of alpha-emitting radionuclides. Importantly, detection does not mean the water is unsafe or violates any health standard. Federal regulations set maximum contaminant levels for uranium and radium, but these must be confirmed by specific lab tests on your household water source to determine if your water exceeds them.
A Worked Example: Interpreting Hampden County's Median and Range as a Homeowner
Government sampling in Hampden County's aquifer 112SRFD collected 16 alpha particle measurements from eight separate wells between April and August 2017. The median concentration was 1.05 pCi/L, ranging from 0.0 to 3.2 pCi/L. None of these samples exceeded federal health-based limits for uranium or radium. As a homeowner, this means the regional groundwater shows measurable alpha activity but remains within accepted safety margins. However, your household water's actual uranium or radium level requires a dedicated test of your specific well water.
Plumbing Material and Age: Separate Factors from Source Water Concentrations
The levels of uranium and radium measured in the aquifer relate to natural geology and aquifer conditions, not to plumbing materials or the age of household pipes. While plumbing can influence taste or cause other water quality issues, it does not alter concentrations of radioactive elements originating from the groundwater source. Understanding this separation is important when considering treatment options for uranium and radium.
What Happens When Uranium-Radium is Left Untreated for Years?
Long-term consumption of water with elevated uranium or radium can potentially increase health risks as defined by federal health standards. Without treatment, these constituents remain present in your water supply at the levels found in your source water. Since Hampden County’s sampled wells remained below regulatory limits, the risk is regionally low, but individual well testing is critical. Untreated water continues to deliver the naturally occurring levels in the source, and no natural reduction occurs without intervention.
How the Pentair Uranium & Radium System Addresses These Constituents
The Pentair Uranium & Radium System is designed to remove alpha-emitting radionuclides from household water. It uses filtration and treatment technology that targets uranium and radium specifically, effectively reducing their concentrations to below detectable levels in many cases. The system’s grain capacity of 32,000 ensures sufficient treatment longevity for typical residential water usage. It ships ready to configure for connection with your existing water setup.
Sample Size and Representativeness: What the Government Data Means
The government’s data for Hampden County's aquifer 112SRFD is based on 16 alpha particle results from eight wells sampled over a four-month period in 2017. This sample size provides a regional snapshot showing that uranium and radium levels fall within federal safety standards. However, the relatively small number of samples means conditions can vary at individual wells. To know your household water status, a specific lab test of your water source is necessary.
In summary, the U.S. Geological Survey data for Hampden County's aquifer 112SRFD shows detected alpha particle activity in all measured samples but none exceeding federal limits. This record is based on multiple wells across the area sampled between April and August 2017.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-08-10. 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.
On record: U.S. Geological Survey sampling of Alpha particle in the 112SRFD aquifer (Hampden County): 16 results from 8 wells, median 1.05 pCi/L, range 0.0-3.2 pCi/L; none above any federal threshold
