Questions Commercial Operators Consider That Differ From Households
Scale and Regulations
Commercial and industrial water users often face stricter regulations and must monitor radon more frequently due to higher water volumes and potential employee exposures. Households generally reference local sampling and focus on personal health and water use.
Water Volume and Contact Time
Businesses may evaluate how water treatment interacts with large volume demand and flow patterns, impacting radon removal efficiency differently than residential systems.
How Large or Seasonal Properties Affect Radon Considerations
Water Usage Patterns
Second homes or seasonal properties may have different water stagnation times, which can affect radon concentrations at the tap compared to continuously occupied houses.
System Sizing
Larger households require treatment technologies sized for higher water flows and consumption, which can influence the choice and configuration of radon treatment systems.
Why Aesthetic Secondary Standards Differ From Health-Based Limits for Radon
Radon's Unique Status
Radon is a radioactive gas, not a typical taste or odor concern targeted by secondary standards. Its limits focus on health risk, not aesthetic effects.
Range and Median From Area Samples
U.S. Geological Survey sampling in Hamilton County bedrock wells found radon-222 present in all samples with a range from 164.0 to 1470.0 pCi/L and a median of 820.0 pCi/L. None exceeded federal thresholds.
Household Water Symptoms Related to Radon Presence
What Symptoms Do Not Indicate Radon
Radon in water does not cause taste, odor, discoloration, or staining. These symptoms usually indicate other water quality issues.
Invisible Risk Factor
Because radon is a colorless, odorless gas dissolved in water, its presence is not detectable by household symptoms and requires testing to confirm.
Changes at the Tap After Using Fleck Radon in Water Filter
Reduction of Radon Gas in Water
The Fleck Radon in Water Filter system reduces radon concentrations by treating water before it exits the tap, addressing the dissolved radon-222 gas in household water supplies.
Preservation of Water Quality
This treatment maintains water taste and appearance as it focuses on radon removal without altering other water qualities.
Information to Record Before Seeking Treatment Guidance
Well Depth and Source Type
Note your well’s depth and whether the water source is bedrock, as these influence radon likelihood and treatment needs.
Previous Radon Test Results
Have any certified lab radon testing results ready, including sample dates and measured concentrations.
Household Water Usage Details
Document water consumption patterns and any water system characteristics that might affect treatment.
Next Step: Confirming Radon Levels in Your Water
The only way to determine your household’s radon concentration in water is a certified laboratory radon test on a current water sample. A test result below federal thresholds can settle the need for treatment. If your results show elevated radon, the Fleck Radon in Water Filter system is a documented solution designed to reduce radon in household water supplies.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2020-09-10. 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 BEDROCK aquifer (Hamilton County): 7 results from 6 wells, median 820.0 pCi/L, range 164.0-1470.0 pCi/L; none above any federal threshold
