Is radon in your home's water a serious concern? Government sampling in Maricopa County's aquifer N100BSNRGB found radon-222 present in three wells at depths between 1100 and 1200 feet, with concentrations ranging widely from 350 to 1070 pCi/L, and a median value around 770 pCi/L. None of these results exceeded federal radon thresholds. What does this mean for your water and what can you do about it?

How a Specialized Water Filter Reduces Radon in Household Water

Radon is a naturally occurring radioactive gas that can dissolve into groundwater. When water containing radon is used in the home, the gas can be released into indoor air, adding to radon exposure. A documented technology solution, the Autotrol Radon in Water Filter, treats water by reducing radon levels before water reaches household faucets. This system ships ready to configure and uses media specifically designed to trap radon, decreasing its concentration effectively as water passes through.

Why Aesthetic Standards Differ from Health-Based Radon Limits in Water

It's common to confuse taste or odor limits with health-related radon standards, but they are separate concerns. Aesthetic secondary standards regulate things like water appearance or unpleasant smells—none of which directly relate to radon. Federal radon thresholds focus strictly on potential health impacts. The government sampling data referenced here did not find radon levels that exceed any health-based federal standards in Maricopa County, highlighting the difference between detection and regulatory concern.

Questions Unique to Commercial or Industrial Operators Compared to Households

While household water treatment aims at reducing radon exposure indoors, commercial or industrial users may require additional information. They often must assess water's impact on equipment and large-scale processes, which might involve continuous monitoring or compliance with workplace safety regulations. These operators might also consider broader testing to understand radon's behavior under varying water volumes or treatment conditions beyond typical residential use.

What the Radon Range in Maricopa County Groundwater Indicates About Federal Standards

The range of radon concentrations measured in sampled wells—from 350 to 1070 pCi/L—shows variation across locations within Maricopa County's aquifer. Although these are detections and not violations, the consistency of results below federal standards indicates radon presence without legally defined hazard. This area-wide median provides context but does not specify individual household levels, which can only be known by testing your own water.

What Distinguishes Radon Concerns from Other Common Water Issues

Radon is a radioactive gas, differing fundamentally from other water concerns like mineral staining or microbial contamination. Its volatility means it can move from water into indoor air, whereas many other water problems remain within the liquid. Unlike issues that affect taste or appearance, radon requires specific testing and filtration approaches, making it a distinct category in water treatment considerations.

To determine your water's radon concentration accurately, the single necessary step is to have a certified laboratory test your household water sample. This test result will clarify whether your water requires treatment. If radon levels exceed health-based guidelines, the Autotrol Radon in Water Filter offers a proven way to reduce radon before it reaches your tap.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2013-08-05. 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 N100BSNRGB aquifer (Maricopa County): 3 results from 3 wells, median 770.0 pCi/L, range 350.0-1070.0 pCi/L; none above any federal threshold
