Many households in Martin County notice a distinctive earthy or musty taste or smell in their tap water, leading to concerns about radon. When existing water equipment fails to address these issues, it becomes important to understand what government sampling says about radon presence in the local aquifer, and what it truly means for residential water.
What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page
The U.S. Geological Survey sampled three wells in the Martin County aquifer between November 20 and December 2, 2019. Radon-222 was detected in all three samples, with a median concentration of 235.0 picocuries per liter (pCi/L) and a range from 215.0 to 290.0 pCi/L. These figures reflect measurements from those specific wells only, each 115 to 125 feet deep, and do not represent the water from any individual household well.
Detection simply means the instrument measured radon; it does not imply a violation or unsafe level. None of the samples were above any federal threshold, so these measurements are within recognized regulatory expectations for groundwater in the area.
How Many Samples and Wells Stand Behind the Figures, and What a Small Sample Means
The data comes from only three wells sampled during a short time window. While this offers useful insight into the regional aquifer's radon levels, the small number of samples limits the ability to capture full variability over time or across all local wells. Individual wells may differ, which is why homeowners need testing tailored to their own water supply to understand their actual radon exposure.
What Questions a Commercial or Industrial Operator Adds That a Household Does Not
Commercial and industrial water users often require more extensive radon data covering multiple depths, pumping rates, and seasonal patterns to match treatment capacity to fluctuating needs. Households typically focus on ensuring consistently treated water for drinking and daily use, requiring less complex data but still benefiting from accurate radon testing and an appropriate treatment system.
How the Treated Water Differs at the Tap Once the Documented Technology Is in Place
The C-Series Radon in Water Filter is designed specifically to reduce radon levels from a household water supply. When in use, treated water at faucets and fixtures shows significantly lowered radon concentrations, improving overall water quality. This system ships ready to configure for home use, providing a reliable way to address radon concerns when existing equipment no longer performs adequately.
What Happens When This Problem Is Left Untreated for Years, Stated Without Exaggeration
If radon in household water is not addressed, radon gas can enter indoor air through water use, such as showering and cooking. Over time, radon accumulation indoors contributes to overall radon exposure, which is a consideration for health agencies. While government sampling shows typical aquifer levels in Martin County, testing your own water supply is the only way to know your household’s condition and decide on treatment.
These radon figures come from three wells sampled in the Martin County aquifer, as reported by the U.S. Geological Survey in late 2019. For full details, visit the official government monitoring site at waterdata.usgs.gov.

Source: USGS groundwater sampling. Sampled 2019-12-02. 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.
