Reading Radon Test Results from Sullivan County’s Groundwater Sampling
Laboratory reports for Radon-222 in water typically list concentrations measured in picocuries per liter (pCi/L). The U.S. Geological Survey conducted groundwater sampling in Sullivan County within aquifer 327MCCK, testing four wells 145 to 245 feet deep from August to November 2012. Across ten samples from these wells, Radon-222 was detected in every result, with a median of 690 pCi/L and a range from 280 to 15,300 pCi/L. Although these measurements show variability characterizing the local aquifer, none of the samples exceeded any federal thresholds established for radon in water. These findings represent regional conditions and are not specific to any individual household’s well.
Which Household Water Uses Are Most Affected by Radon Presence?
Radon gas dissolved in water primarily impacts indoor air quality when the water releases radon upon use. Activities like showering, cooking, and using hot water appliances release dissolved radon into the air. Fixtures such as showers and faucets are key points where radon escapes from water and becomes airborne. Since radon is a gas that volatilizes easily, the air in home spaces where water is agitated or heated will first experience elevated radon levels related to water use, rather than the water itself posing a direct ingestion risk under typical regional measurements.
What Additional Concerns Are There for Commercial or Industrial Water Users?
Commercial and industrial water users often require more extensive evaluation due to larger water volumes and increased potential for airborne radon exposure. Questions arise about the effects of radon on workplace air quality, compliance with occupational safety standards, and potential impacts on sensitive manufacturing processes. They may also consider treatment scalability and continuous monitoring needs. In contrast, residential concerns focus mainly on household air quality and mitigating exposure through water treatment options appropriate for smaller volumes and home use.
How Do Public Water System Records Differ from Private Well Testing for Radon?
Public water systems in Sullivan County maintain radon monitoring records based on routine sampling across their distribution networks. These records reflect average local conditions and regulatory compliance but do not account for private well variations. Private groundwaters can show different radon levels because of local geology and depth variations. Only a certified laboratory test of a household’s own water sample can determine the exact radon concentration in that specific well. Thus, public records are useful for general regional understanding but not a substitute for individual household testing.
How Is Radon Different from Other Common Water Concerns Often Confused with It?
Radon is a radioactive gas naturally released from bedrock that dissolves into groundwater. It is unlike chemical contaminants such as iron or sulfur compounds, which cause taste or odor issues but are not gases nor radioactive. Radon differs from microbial contamination that involves bacteria or viruses, as radon is a physical radioactive constituent without microbial origin. Understanding these differences clarifies that radon-related concerns focus on airborne release from water and its radioactivity rather than typical water quality issues like staining or odor.
What Happens If Radon in Water Is Left Untreated Over Years?
When radon from water is not addressed, it can contribute to indoor air radon levels, especially in enclosed spaces with poor ventilation. Over extended periods, this increases the potential for inhalation exposure. While the federal guidelines provide thresholds aiding decisions on mitigation, untreated elevated radon in water does not necessarily mean immediate or severe health effects but justifies consideration based on test results and household circumstances. Continuous assessment and informed decisions help manage long-term exposure realistically.
In summary, this page has clarified what Sullivan County’s regional radon water data indicate, how the household experiences radon during water use, and why personal water testing matters.

Source: USGS groundwater sampling. Sampled 2012-11-08. 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.
