If You Want to Compare Bexar County Radon Data with Neighboring Areas, What Should You Know?
The U.S. Geological Survey sampled groundwater across Bexar County, Texas, focusing on aquifer 218EDRDA between 2013 and 2017. Radon-222 was detected in all 19 measurements from 16 wells ranging from 229 to 2,326 feet deep, with median concentration at 78.0 picocuries per liter (pCi/L) and values spanning from 8.0 to 570.0 pCi/L. Importantly, none of these results exceeded any federal thresholds, indicating regional measurements remain within regulatory expectations.
When reviewing data from nearby counties or aquifers, it is vital not to interpret these figures as a direct reflection of your home's water. Regional samples offer context about typical radon presence but cannot establish your household’s specific level without individual water testing.
If Your Existing Radon Treatment Equipment Has Failed, How Does the C-Series System Address Radon in Water?
The documented treatment technology known as the C-Series Radon in Water Filter is designed to reduce radon levels in water supplies similar to those sampled in Bexar County. This system works by facilitating processes that remove or neutralize radon gas dissolved in water before it reaches your tap. It ships ready to configure, providing a way to renew your home's defense against radon without relying on previously functioning equipment.
How Does Seasonal or Multi-Year Variation Appear in the Bexar County Radon Record?
The data collected from November 2013 through December 2017 captures radon levels across multiple years and seasons. This range reflects natural fluctuations in groundwater radon concentrations over time, influenced by factors such as aquifer recharge rates and climatic variations. Consequently, radon measurements may rise or fall seasonally but tend to remain within the documented range from 8.0 to 570.0 pCi/L during this period.
Which Home Fixtures and Water Uses Are Impacted First When Radon Is Present in Water?
Radon dissolved in water primarily affects water fixtures that aerate the water or use it in ways that release gas into indoor air. These include showers, faucets, and appliances that agitate water, such as washing machines. Since radon is a gas, exposure risks increase during water use that promotes its release into air, so addressing radon in water is critical to reducing potential indoor radon levels.
How Does Radon Enter Groundwater in Bexar County’s Aquifer?
Radon-222 is a naturally occurring radioactive gas generated by the decay of uranium in soil and rock formations. In Bexar County's aquifer 218EDRDA, radon seeps into the groundwater through the surrounding geologic materials. Wells tapping this aquifer draw water that can carry dissolved radon gas, reflected in the detected measurements across sampled wells.
For a household experiencing failure of existing treatment equipment, understanding these factors and testing the specific water source are key to determining the appropriate next steps.
To restore effective mitigation of radon in your home water, the C-Series Radon in Water Filter offers a proven technology tailored to the radon levels documented in Bexar County's groundwater. By selecting a system matched to your measured water demand, you can renew your home's protection against radon exposure from water.

Source: USGS groundwater sampling. Sampled 2017-12-19. 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 218EDRDA aquifer (Bexar County): 19 results from 16 wells, median 78.0 pCi/L, range -8.0-570.0 pCi/L; none above any federal threshold
