Uranium-Radium in Gloucester County Homes: Understanding Regional Range and Residential Impact

If Your Water Problem Isn’t Iron or Hardness, but Mineral Radioactivity

Many households in Gloucester County experience water issues they first assume are related to common elements like iron or hardness. However, uranium and radium, naturally occurring radioactive minerals, can also be present in the groundwater sourced from aquifer 121CKKD. This distinguishes them from non-radioactive minerals typically considered in water treatment. Unlike iron or hardness minerals that often cause staining or buildup, uranium and radium require specialized attention due to their distinct chemical and physical behavior.

If You Review Regional Sampling Results, How Should You Read Them?

The U.S. Geological Survey has sampled 38 groundwater wells in Gloucester County’s aquifer 121CKKD between 2010 and 2018, measuring radium-226 levels. The median concentration found was 1.595 picocuries per liter (pCi/L), with a range from 0.07 to 6.6 pCi/L. Every sample detected radium-226, but no result exceeded any federal threshold. These results describe regional water conditions, not your specific well. To understand your own water composition, testing of your household supply is necessary.

If Your Plumbing System Is Older or Uses Certain Materials, How Does That Affect Your Uranium-Radium Concern?

Plumbing materials and system age can influence how minerals and contaminants behave once water enters your home. Older pipes or certain materials can interact with water chemistry, potentially affecting mineral accumulation or corrosion rates. These factors are independent of the source water's radium concentration but may affect the overall household water quality and the efficiency of any treatment system you choose.

If Your Household Size or Usage Pattern Changes, What Are the Implications for Uranium-Radium Management?

Larger households, seasonal homes, or properties with fluctuating water usage may find that standard treatment systems struggle to keep up with demand. The documented Pentair Uranium & Radium System offers a grain capacity of 32,000, reflecting its ability to handle significant water volumes before maintenance is needed. Understanding your water demand is essential to selecting a treatment approach that remains effective over time and adapts to changes in household water consumption.

If You See Quality Changes in Specific Fixtures or Appliances, What Does That Indicate?

Fixtures and appliances using significant amounts of water, such as kitchen sinks, washing machines, or water heaters, often show symptoms of uranium and radium presence first. These minerals can contribute to mineral buildup and affect taste or odor. Early recognition of these changes can guide decisions about water testing and treatment. Addressing uranium-radium concerns at these points optimizes household water quality and appliance longevity.

What You Should Not Conclude Solely from Gloucester County Aquifer Data

Regional groundwater sampling provides useful context but should not be taken as a direct indication of your household’s water quality. Detection of radium-226 in aquifer 121CKKD wells does not mean your water is unsafe or that it exceeds any health-based limit. Only a specific test of your well or tap water can show the actual uranium and radium levels you must address. When equipment currently in use cannot keep up, the Pentair Uranium & Radium System ships ready to configure as a documented solution designed specifically for residential uranium and radium concerns in this region.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2018-09-04. 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 121CKKD aquifer (Gloucester County): 38 results from 31 wells, median 1.595 pCi/L, range 0.07-6.6 pCi/L; none above any federal threshold
