What Happens When Radon in Water Is Left Untreated for Years

Radon is a naturally occurring radioactive gas found in groundwater

When radon dissolves into household water from wells, it can release into indoor air and contribute to exposure. Long-term exposure to elevated radon levels is associated with health risks, especially lung cancer from inhalation. However, radon in water is generally less of a direct exposure source than air radon.

Untreated radon in water may affect indoor air radon levels

Radon released during showering, cooking, and laundry can increase indoor air concentrations. This is a consideration over years of continuous exposure, although the actual risk depends on the radon content in your well water.

The radon concentrations found in Gloucester County groundwater are below federal health thresholds

Sampling in the Gloucester County aquifer 211MRPAM between December 2021 and November 2022 found radon-222 levels ranging from 46.0 to 102.0 pCi/L with a median of 72.0 pCi/L. None of these results exceed federal action levels, suggesting water in this area commonly remains below regulatory concern.

How Seasonal or Multi-Year Variation Shows in the Radon Record

Sampling dates span nearly one year

Three radon measurements from separate wells were collected between December 7, 2021, and November 22, 2022. This period covers seasonal changes that can affect groundwater conditions.

Radon levels in this area show some range but no large fluctuations

The detected values between 46.0 and 102.0 pCi/L indicate moderate variation across wells and over this timeframe. This suggests radon concentrations may shift slightly but stay within a certain range in this aquifer.

Individual well radon may vary differently

The samples represent different locations and depths (138 to 210 feet), so your own well could have a radon concentration outside this range. The data do not substitute for testing your household water.

Household Symptoms That Do and Do Not Point to Radon in Water

Radon in water does not cause taste, odor, or visual changes

Unlike some water contaminants, radon is colorless, odorless, and tasteless. If you notice unusual water taste or smell, radon is an unlikely source.

Symptoms from radon are related to long-term inhalation, not immediate water effects

Health effects linked to radon arise mostly from breathing radon gas released indoors during water use, not from drinking the water directly. There are no immediate symptoms from radon exposure in water.

Indoor air radon testing is important to understand overall exposure

Even if water radon is present, monitoring radon in indoor air provides better insight into risk. Water can be a contributing source, especially with private wells.

What Additional Questions Commercial or Industrial Operators Consider

Volume and continuous use affect radon treatment needs

Operators managing larger water volumes may need to assess treatment system capacity differently than households, considering flow rates and peak demands.

Regulatory compliance and reporting requirements are more complex

Commercial users often have to follow specific testing schedules, maintain records, and meet occupational safety standards beyond household guidelines.

Engineering controls and system integration are evaluated

Businesses may analyze how radon reduction fits with other water treatment or process systems, requiring detailed planning not typical for residential users.

Which Household Fixtures, Appliances, or Processes Are Affected First and Why

Showers and baths release radon gas directly into indoor air

Activities that agitate water, such as showering or filling bathtubs, facilitate radon release, influencing indoor air concentrations more quickly.

Water heaters and laundry machines also contribute to radon degassing

Heated water releases radon gas, so appliances using hot water can increase indoor air radon levels.

Faucets and cold water use have less impact on indoor air radon

Cold water use without agitation releases less radon gas into the home environment.

Addressing Radon in Gloucester County Household Water

To determine your water’s radon concentration, laboratory testing of a water sample from your own well is necessary, as area data cannot define individual results. For reducing radon in household water supplies in Gloucester County, the Fleck Radon in Water Filter ships ready to configure and offers a documented approach to lowering radon levels based on the amount measured in your water.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2022-11-22. 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 211MRPAM aquifer (Gloucester County): 3 results from 3 wells, median 72.0 pCi/L, range 46.0-102.0 pCi/L; none above any federal threshold
