How Uranium and Radium Enter Groundwater in Suffolk City Aquifer 217PTMC
In Suffolk City, groundwater from aquifer 217PTMC may contain naturally occurring uranium and radium, which originate from mineral deposits in the earth’s crust. These radioactive elements can dissolve into the water as it moves through rocks and soil layers, especially in deep wells ranging from about 500 to 1775 feet. This process is natural and varies based on localized geology.
Differences Between Public-System Records and Private-Well Testing
The public water system records for Suffolk City’s aquifer 217PTMC come from testing multiple wells across the area, providing median and range values for radium-226. These results offer a regional overview but do not describe an individual household’s water quality. Private well owners must conduct their own water tests to determine uranium and radium levels since local conditions and well depth can cause significant variation.
The Number of Samples and Wells Behind Available Data and What Small Samples Mean
The U.S. Geological Survey collected 10 radium-226 results from 3 wells sampled between March 2019 and March 2022. While this sampling gives a useful snapshot of groundwater quality in the aquifer, the small number of wells and samples means some locations may differ. A limited dataset underscores the importance of testing each private well for accurate information.
Potential Effects of Leaving Uranium-Radium Untreated Over Time
If uranium or radium is present in private well water and left untreated, it may contribute to long-term exposure to low-level radioactivity. This scenario does not mean an immediate violation of health-based limits; in Suffolk City, none of the samples exceeded any federal thresholds. Still, chronic exposure may warrant consideration of water treatment to reduce these constituents.
Maintenance Rhythm of the Pentair Uranium & Radium System in Plain Terms
The Pentair Uranium & Radium System ships ready to configure and requires routine maintenance based on water usage and contaminant levels. Typically, resin media capacity is rated at 32,000 grains. Over time, the system’s filtering components will need timely media replacement or regeneration to maintain effectiveness in reducing uranium and radium concentrations.
How Treated Water Differs at the Tap with the Pentair Uranium & Radium System
When working within its design parameters, the Pentair System reduces uranium and radium levels in household water, improving overall water quality at the tap. Treated water will have significantly lowered concentrations of these naturally occurring radioactive elements compared to untreated water, helping households manage exposure while retaining water clarity and taste.
This overview is based on U.S. Geological Survey groundwater sampling in Suffolk City, VA, for aquifer 217PTMC. The study involved 10 radium-226 results from 3 wells sampled over three years, showing all levels below federal thresholds.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2022-03-16. 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 Radium-226 in the 217PTMC aquifer (Suffolk city County): 10 results from 3 wells, median 0.23 pCi/L, range 0.04-16.5 pCi/L; none above any federal threshold
