Radon in Union County Water: Key Factors for Households in Aquifer 124SPRT
Questions Unique to Commercial or Industrial Operators
Regulatory Reporting Needs Differ
Commercial or industrial users often must meet specific regulatory thresholds and conduct frequent radon monitoring due to larger water volumes and business risk factors.
Process Impact Considerations
Industries may require detailed analyses on radon’s interaction with equipment and product quality, beyond what is a concern for household use.
Water Treatment Complexity
Commercial operations might integrate radon treatment into comprehensive water management systems, unlike simpler residential approaches.
Long-Term Effects of Untreated Radon in Household Water
Potential Indoor Air Contribution
Radon released from water during showering or cooking can add to indoor airborne radon, which is a recognized health consideration over years of exposure.
Water Taste and Odor
Radon itself does not cause taste or odor issues; however, its presence signals the need for assessment when correlated with other water characteristics.
Corrosion and Staining Are Not Typical
Radon in water does not cause staining or corrosion, unlike some other minerals.
Changes in Tap Water After Using Fleck Radon in Water Filter
Reduced Radon Activity
The Fleck Radon in Water Filter is designed to lower radon levels in household water, improving overall water quality where radon is detected.
Water Quality Maintained
The filter operates without negatively impacting other water qualities such as hardness or mineral content.
Ready to Configure for Household Use
The system ships ready to configure, allowing households to address radon without complex adjustments.
Scope and Limitations of Area Radon Sampling Data
Sample Size and Distribution
Eleven samples from nine wells, ranging 260 to 771 feet deep, were collected between 2012 and 2014 within Union County’s aquifer 124SPRT area.
Radon Range and Median
Measured radon ranged from 54.0 to 320.0 pCi/L with a median of 77.0 pCi/L, all values below federal action levels for drinking water.
Data Does Not Reflect Individual Wells
These results are from tested wells in the area but may not represent radon levels in any specific household water supply.
Household Fixtures and Processes Most Affected by Radon in Water
Water Aeration Points
Fixtures like showers, faucets, and dishwashers release radon to air more than others, potentially increasing household airborne radon.
Hot Water Usage
Hot water systems may accelerate radon release from water, influencing indoor air levels.
Water Storage Tanks
Tanks may allow radon to dissipate before use but do not eliminate radon content in water itself.
What You Should Not Conclude from Area Radon Data
The radon levels measured by the U.S. Geological Survey in Union County’s aquifer 124SPRT indicate detectable radon but do not reflect your household’s water radon concentration. Only a test of your own well or water source can determine your specific radon level. If radon is a concern for your water, using the Fleck Radon in Water Filter provides a documented solution to reduce radon effectively at home.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-08-12. 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 124SPRT aquifer (Union County): 11 results from 9 wells, median 77.0 pCi/L, range 54.0-320.0 pCi/L; none above any federal threshold
