Government monitoring of groundwater in Charles County's aquifer 217PTXN shows that alpha particle activity, associated with uranium and radium in water, was detected in all samples from four wells over several years, with values ranging from negative to 8.5 pCi/L and a median of 0.35 pCi/L. None of these measurements exceeded federal thresholds. This data, gathered from wells 1400 to 2073 feet deep, provides a regional overview but does not determine the quality of any one household's water.
What to Note Before Seeking Treatment Advice
Before deciding on how to address uranium and radium in your household water, document specific information about your water source and quality. This includes the depth and type of your well, any recent water tests measuring alpha particle or radionuclide levels, and any existing water treatment systems. Knowing your household's water usage patterns and whether anyone is more sensitive to water quality changes can also help tailor treatment recommendations.
Additional Questions for Commercial or Industrial Water Users
Commercial or industrial operations must consider factors beyond those for residences, including compliance with stricter discharge permits, potential process water impacts, large volume treatment capacities, and the economic implications of treatment downtime. They may also require detailed records of water quality variations over time and must assess the impact of radionuclide levels on product quality and worker safety.
Household Symptoms Related to Uranium and Radium and Those That Are Not
Presence of uranium and radium in water contributes to measurable alpha particle activity but usually causes no immediate taste, odor, or visible water quality changes. Symptoms such as unusual staining, metallic tastes, or odors generally arise from other water constituents. Uranium and radium concerns focus on long-term consumption and potential radiological exposure rather than acute symptoms. Therefore, symptoms like discoloration or sediment in water are not directly linked to these radionuclides.
Understanding 'Detected,' 'Median,' and 'Range' in This Sampling Record
The term 'detected' indicates that instruments measured alpha particle activity in all sampled wells, but it does not imply any violation or unsafe condition. The 'median' value represents the middle of the measured concentrations, providing an estimate of typical regional levels. The 'range' shows the lowest and highest measurements observed, reflecting natural variability within the aquifer and sampling period. Since no results exceeded federal thresholds, these figures serve as indicators of presence rather than a basis for regulatory action.
How Treated Water Is Different Using the C-Series Uranium & Radium System
The C-Series Uranium & Radium System is designed to reduce alpha particle activity by targeting uranium and radium removal from household water. Once water passes through this system, levels of these radionuclides decrease, resulting in water that meets or surpasses federal benchmarks for radiological safety. This system offers a high grain capacity of 32,000, enabling extended use before maintenance is needed. The treated water presents no change in taste or appearance related to uranium or radium reduction, but it provides peace of mind regarding radiological content.

Source: USGS groundwater sampling. Sampled 2019-05-29. 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 217PTXN aquifer (Charles County): 12 results from 4 wells, median 0.35 pCi/L, range -3.2-8.5 pCi/L; none above any federal threshold
