Local Aquifer and Water Delivery to Your Home

Camden County’s water comes from groundwater sources including aquifer 211MRPAL, a significant underground water reservoir tapped by wells ranging in depth from about 125 to 741 feet. Water drawn from this aquifer travels through pipes into residential plumbing, serving as the source for drinking, cooking, bathing, and other daily uses. Understanding the quality of water from this aquifer helps households make informed decisions about any necessary treatment steps.

Interpreting Radon Levels: A Homeowner's Perspective on Area Data

Government sampling from 2012 through 2024 assessed radon-222 concentrations in water from multiple wells within the Camden County aquifer 211MRPAL. The median radon level recorded was 150.5 picocuries per liter (pCi/L), with measurements ranging from 80.0 to 230.0 pCi/L across 28 samples from nine wells. While these figures indicate radon is present throughout the sampled wells, they do not reveal the specific radon level in any individual household water supply. Only a direct water test from your home can provide that information. These area measurements, however, help set expectations about the potential presence of radon in your household water.

Maintenance Rhythm of the Documented Radon Treatment Technology

The Pentair Radon in Water Filter is designed for ongoing radon reduction in home water systems. It ships ready to configure for use and requires periodic upkeep to maintain its effectiveness. Typical upkeep involves replacing the filtration media or cartridges according to manufacturer guidelines, often yearly or based on water use volume. This schedule helps ensure consistent radon removal performance without interruption.

First Affected Fixtures and Household Processes

Radon present in water most directly impacts fixtures where water becomes aerosolized or vaporizes, such as showers, bathtubs, and kitchen faucets. These points release radon gas into indoor air, where inhalation exposure could occur. Appliances using water for humidification or those that spray water, such as dishwashers and washing machines, also contribute to minor radon release, but to a lesser extent. Addressing radon at the water source reduces overall indoor airborne radon generated by household water use.

Federal Standards and What Area Radon Levels Indicate

The Environmental Protection Agency (EPA) provides guidelines and recommendations for radon in water, but no enforceable federal maximum contaminant level specifically applies to radon in drinking water. The sampled radon concentrations in Camden County aquifer 211MRPAL wells were all below any federal limit related to health concerns. This means the measured radon levels do not constitute a violation of any federal standard. However, the presence of radon, even at these levels, can contribute to indoor air radon. Deciding to implement treatment depends on your household’s radon test results and personal health risk considerations rather than area measurements alone.

Information to Document Before Seeking Treatment Advice

Before pursuing treatment, gather key information to inform your decision. This includes the depth of your well, the radon concentration measured in your household water, typical daily water use, and whether your home has a radon-in-air test. Documenting any previous water treatment systems or filtration equipment is also helpful. This detailed information supports choosing the most suitable radon reduction approach for your household needs.

Recommended Testing to Resolve Household Radon Concerns

The definitive step to understand your household radon situation is to conduct a direct radon test on your water. A certified water laboratory can measure radon-222 levels specific to your well or water supply. Once this test result is available, it will clarify whether radon removal treatment, such as with the Pentair Radon in Water Filter, is warranted. Knowing your own water’s radon concentration is the critical factor in making the best choice between treatment technologies and achieving safer water use at home.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-08-19. 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 Radon-222 in the 211MRPAL aquifer (Camden County): 28 results from 9 wells, median 150.5 pCi/L, range 80.0-230.0 pCi/L; none above any federal threshold
