Government sampling in Taos County's S100RIOGRD aquifer found radon-222 in all tested wells, with levels ranging from 2200 to 6600 pCi/L and a median of 4400 pCi/L. These results come from five separate wells sampled between July 2014 and July 2015, each drilled between 100 and 500 feet deep. None of these measurements exceed federal thresholds.
Household Size, Second Homes, and Seasonal Properties: What Changes?
For larger households, water usage is generally higher, which can influence the volume of water requiring radon treatment. Similarly, second homes or seasonal properties may have periods of low or no water use, affecting how radon concentration might manifest in the plumbing system. While the radon levels in the source water remain consistent with area measurements, fluctuations in water turnover and usage patterns can affect radon presence in tap water. Choosing equipment that can accommodate these usage patterns ensures that radon reduction is maintained reliably over the times water is used.
Seasonal and Multi-Year Variation in Radon Levels Found in the Record
The government sampling span—from mid-2014 to mid-2015—reveals radon concentrations consistently detected across the year with levels ranging between 2200 and 6600 pCi/L. This shows some variability but no sample fell below detection limits or above federal thresholds. Such variation indicates that radon levels may shift somewhat due to environmental or groundwater changes but remain present year-round in the aquifer system.
Distinguishing Radon Concerns from Other Water Issues
Radon in water is often confused with other common water concerns such as bacterial contamination or mineral hardness. Unlike these, radon is a radioactive gas originating naturally from uranium decay in underground rock and soil. It dissolves into groundwater and then enters homes through water use. Radon presence does not cause typical water taste, odor, or appearance changes. This makes it different from issues like iron or sulfur, which have clear sensory signs.
Sampling Scope and the Meaning of Limited Well Data
The radon data discussed is based on five wells sampled once each across a year in the S100RIOGRD aquifer. While this provides a snapshot of the regional aquifer conditions, it does not specify radon levels in any individual household's water. A small sample size means local or well-specific variations may exist. To know the exact radon concentration for your water supply, a dedicated test of your own well or water system is necessary.
How Radon Enters the Groundwater System in Taos County
In Taos County, radon originates from natural uranium decay in surrounding geological formations. As groundwater moves through rock and soil that contain uranium, radon gas dissolves into the water. The depth range of the sampled wells (100 to 500 feet) corresponds to typical aquifer zones where radon can accumulate. Unlike surface water contamination, this process is natural and depends on local geology rather than human activity.
Overall, the government record for Taos County's S100RIOGRD aquifer shows consistent radon presence in groundwater but within federal limits. Households seeking treatment can consider the C-Series Radon in Water Filter, a system designed to reduce radon levels effectively. It ships ready to configure for home water systems and can help manage radon concerns regardless of household size or water use patterns.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2015-07-13. 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 S100RIOGRD aquifer (Taos County): 5 results from 5 wells, median 4400.0 pCi/L, range 2200.0-6600.0 pCi/L; none above any federal threshold
