Water in Doña Ana County commonly draws from aquifer 112SNTF, a deep underground source spanning multiple wells. Water flows to households through pumps and pipes, carrying with it natural elements including radon, a radioactive gas that dissolves from surrounding rocks and soil.
What You Should Record Before Requesting Radon Treatment Advice
Before considering additional water treatment options, gather information about your household water use and any existing equipment managing radon. Knowing how much water you consume daily and the capacity of your current system helps determine if new treatment will keep pace. Documenting water source depth can also inform expectations since deeper wells might have different radon exposures.
How Water Quality Changes When Using the Pentair Radon in Water Filter
When configured with this system, radon concentrations at your tap can be significantly lowered, reducing associated risks. This treatment works continuously, maintaining radon at reduced levels under typical household demand. Your water's taste, appearance, and odor remain unaffected, while radon gas levels decrease as the filter traps or removes it before water reaches the faucet.
How Radon Naturally Enters Groundwater in This Region
Radon originates from uranium decay found in the earth's crust, especially abundant in geological formations of southern New Mexico. It moves into groundwater through soil pore spaces and fractures, dissolving as water passes through rock layers. This process leads to natural radon presence in wells tapping aquifer 112SNTF.
How Well Depth Influences Radon Levels in Household Water
Data from 34 samples taken between 2010 and 2015 across wells ranging from 147 to 1322 feet deep show radon concentrations vary widely. Median levels were 325.0 pCi/L with a range extending up to 2180.0 pCi/L. Although these figures reflect area conditions, individual well radon will differ. Deeper wells might encounter higher or lower radon due to geological variations.
How the Pentair System Reduces Radon Effectively
This filter uses specialized media designed to remove radon from water before it reaches your taps. It operates by adsorbing radon gas and preventing it from dissolving into treated water. This technology ships ready to configure, providing an immediate solution without complex setup. Its design suits residential needs for radon mitigation in water.
To truly determine radon levels in your home water supply, ordering a specific radon-in-water test is essential. Testing your well water directly provides the only accurate measure of radon concentration for your household. Results from this analysis will clarify whether current treatment suffices or if upgrading with a Pentair Radon in Water Filter is warranted.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2015-07-08. 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.
On record: U.S. Geological Survey sampling of Radon-222 in the 112SNTF aquifer (Doña Ana County): 34 results from 31 wells, median 325.0 pCi/L, range 91.0-2180.0 pCi/L; none above any federal threshold
