Radon in Navajo County Water: Understanding Aquifer Levels and Treatment Options
The Navajo County Aquifer and How Water Arrives at Your Home
Navajo County's water supply often comes from the N300COPLTS aquifer, a deep underground source that varies in depth from 150 to 700 feet at sampled wells. Groundwater drawn from this aquifer travels through natural geological layers before reaching residential taps, carrying with it constituents measured in the area including radon-222, a naturally occurring radioactive gas. Understanding local water composition is vital when considering treatment solutions for radon because it influences your water quality and informs appropriate countermeasures.
Distinguishing Radon From Commonly Confused Water Problems
Radon in water can sometimes be confused with other water quality issues like iron or sediment, but it is chemically and behaviorally distinct. Unlike particulate matter or dissolved minerals causing taste or staining issues, radon is a radioactive gas that dissolves in water and can be released into the air during household water use. Recognizing radon’s gaseous nature and its source being natural radioactive decay separates it from chemical contaminants or aesthetic concerns often addressed by standard water filtration.
What Information to Note Before Seeking Treatment Advice
Prior to choosing a treatment method, it helps to record specific details about your water source and radon presence. Note the depth of your well and the results of any radon testing performed on your household water. Government data from Navajo County’s N300COPLTS aquifer show radon-222 was detected in three wells with a median of 400 picoCuries per liter (pCi/L), ranging from 380 to 430 pCi/L. While none of these values exceed federal thresholds, individual well results can differ and should be verified by a certified test.
Interpreting the Area’s Radon Values: A Navajo County Homeowner’s View
Consider the median and range from the official sampling as a general guide. A median value of 400 pCi/L indicates that half of the sampled wells recorded radon levels above this point, with variations between 380 and 430 pCi/L in the sample set. This range reflects natural variability in groundwater radon concentrations depending on factors like well depth and geology. For a homeowner, these figures highlight the possibility of radon presence at moderate levels but do not establish specific conditions for any single well.
How Fleck Radon in Water Filter Treats Radon
The Fleck System addresses radon in water by effectively removing this gas through a specialized filtration process designed for residential use. Unlike general filtration systems, it targets radon specifically, reducing its concentration before water reaches household taps. This direct purchase product ships ready to configure and can be adapted to suit household demand factors. Using such a system can mitigate radon release indoors, complementing other safety measures like air ventilation.
Comparing Navajo County’s Radon Levels With Neighboring Areas
When looking at radon data from nearby counties, it's important to avoid assuming uniformity. Geological differences mean radon presence can vary significantly. The median of 400 pCi/L in Navajo County’s N300COPLTS aquifer is specific to that aquifer and sampling period. While neighboring counties may report higher or lower values, these should not be directly applied to a specific home's water but rather used for regional context. Localized testing is necessary to determine household conditions accurately.
Final Step: Getting Your Household Water Tested
The definitive way to understand radon levels in your home's water is to order a certified laboratory radon test specific to your well. This test isolates your water quality and provides the data needed to justify or rule out treatment. A result showing radon concentration above your personal or regulatory threshold would confirm the need for targeted treatment options such as the Fleck Radon in Water Filter. Without this test, decisions about radon treatment remain based on regional estimates rather than your household’s actual water condition.

On record: U.S. Geological Survey sampling of Radon-222 in the N300COPLTS aquifer (Navajo County): 3 results from 3 wells, median 400.0 pCi/L, range 380.0-430.0 pCi/L; none above any federal threshold
