What Changes for a Large Household, a Second Home, or a Seasonal Property
Larger households or those with fluctuating occupancy, such as second homes or seasonal residences, can notice that existing equipment to manage Radon in drinking water struggles to keep up with water demands. Increased water use means the volume of Radon entering the household's water system can be higher, and treatment capacity may be strained or less effective over time. Seasonal properties might experience variations in Radon concentration due to differences in groundwater levels during unoccupied periods, impacting water quality upon return.
How the Treated Water Differs at the Tap Once the Documented Technology Is in Place
Once the Fleck Radon in Water Filter system is configured, treated water at the tap will have Radon levels reduced through specialized filtration technology designed to address this gas. The system works continuously to lower the Radon concentration, helping to mitigate the presence of Radon gas dissolved in water before it enters household plumbing. While the treated water maintains the same essential qualities for household use, the Radon reduction contributes to peace of mind regarding this naturally occurring radioactive gas.
How Seasonal or Multi-Year Variation Shows in the Record (Dates and Ranges Given)
The U.S. Geological Survey recorded Radon-222 levels in Richmond County's aquifer 125DBLNL from June 28, 2021, through July 7, 2025. Three samples taken from one well at depths around 120 feet showed Radon concentrations ranging from 162.0 to 184.0 picoCuries per liter (pCi/L), with a median of 170.0 pCi/L. These values demonstrate limited but measurable variation within the sampling period. Seasonal groundwater fluctuations and local geological factors contribute to these changes, but they remain within the sampled range without exceeding federal thresholds.
A Worked Example: Reading the Record's Median and Range as a Homeowner Would
Imagine you see the Radon level of 170.0 pCi/L listed as the median in government data for Richmond County aquifer 125DBLNL. This means half the readings fall below this and half above it. The range from 162.0 to 184.0 pCi/L shows the spread of measured values over four years. Your own home's water might differ, possibly higher or lower, because these figures describe the aquifer generally, not a specific well. To understand your water’s Radon concentration precisely, a certified laboratory test of your well or tap water is necessary.
What the Measured Range Means Against the Relevant Federal Standard, and What It Does Not Mean
The federal standard for Radon in water currently provides guidance but no enforceable maximum contaminant level specifically for Radon. The U.S. Geological Survey's measurements for Richmond County did not exceed any federal threshold. Detection of Radon in these samples is expected given the local geology and does not indicate a violation or unsafe condition by itself. Homeowners should view these numbers as helpful area context rather than direct measures of their water’s safety or compliance.
What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page
'Detected' means the testing equipment measured Radon-222 at levels above the reporting limit in all three samples. 'Median' specifies the middle value in the set of samples collected, reflecting a central tendency rather than a fixed value for any one well. 'Range' represents the lowest and highest Radon figures found in the sample set. These terms help clarify what the government data report but do not reveal the Radon content of an individual's water supply without specific testing.
In summary, the U.S. Geological Survey sampling in Richmond County's aquifer 125DBLNL from 2021 to 2025 found Radon-222 consistently present but below federal thresholds in three samples from one well. This provides valuable regional context but not a direct statement about any home’s water. For households finding their existing equipment challenged by increasing Radon, Fleck Radon in Water Filter ships ready to configure and offers a documented means to reduce Radon levels in water supply.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-07-07. 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 125DBLNL aquifer (Richmond County): 3 results from 1 wells, median 170.0 pCi/L, range 162.0-184.0 pCi/L; none above any federal threshold
