If your household is large, a second home, or seasonal: what changes for radon treatment?

In Doña Ana County, New Mexico, the groundwater radon levels measured in aquifer 110ALVM show a median of 229.0 pCi/L from area sampling, with individual wells ranging between 186.0 and 430.0 pCi/L. These figures represent typical concentrations found across sampled wells 23 to 110 feet deep, not a single household’s water. When your household is larger, uses more water daily, or if your property is a second or seasonal home, the volume of water treated and frequency of use become important factors. Treatment devices need to handle higher flow rates and periods of inactivity without compromising radon reduction efficiency.

Considering these aspects helps determine which class of radon treatment system best suits your needs. Larger households or multiple users may require higher capacity systems that can maintain performance over increased water demand and potential downtime.

If you are a commercial or industrial operator, what additional questions come into play?

For commercial or industrial users, concerns extend beyond household-scale radon removal. These include compliance with workplace safety standards, potential radon exposure through water use in production, and continuous monitoring requirements. Since this page addresses household context, these additional considerations help determine the scale and sophistication of treatment equipment but are not the focus here.

If you are deciding on treatment, what should you document first?

Before selecting a radon treatment solution, note the following details:

• Your household water source type (private well, municipal supply)
• Results of any lab testing for radon-222 specific to your water
• Daily water usage estimates and number of occupants
• Depth and construction details of your well, if applicable

Because government data reports radon in the area but not your specific well, testing your own water for radon-222 concentration is essential to inform treatment needs.

If you are deciding when to test or filter, what is the order to rule things out?

Start with a water test from a certified laboratory to measure radon-222 levels in your water supply. This confirms whether radon is present at levels warranting treatment beyond typical background. Next, assess whether your household characteristics—like size and seasonality—necessitate higher-capacity treatment. Only after establishing these conditions should you select a radon water filter system.

If you are comparing radon to other water concerns, what distinguishes radon here?

Radon is a naturally occurring radioactive gas that can dissolve into groundwater. Unlike taste or odor issues, radon is odorless, colorless, and only detectable through measurement. It differs from minerals or chemical contaminants that affect water aesthetics or safety in different ways. The USGS sampling in Doña Ana County confirms radon is measurable but below federal safety thresholds in sampled wells, emphasizing that detection alone is not a violation or unsafe condition.

If you are reading median and range values in this record, how to interpret them?

The USGS record for Doña Ana County’s aquifer 110ALVM shows radon-222 concentrations from three wells sampled between 2010 and 2014. The median value is 229.0 pCi/L, meaning half the samples measured below and half above this concentration. The range spans from 186.0 to 430.0 pCi/L, reflecting variability across sampled wells. No sample exceeded federal thresholds for radon in water.

As a homeowner, you should not assume your water falls within this range or at the median. Instead, use this data to understand regional radon occurrence and confirm your home's specific levels by laboratory analysis.

Summary and next steps

The US Geological Survey’s sampling in Doña Ana County aquifer 110ALVM establishes that radon-222 is present in groundwater at detectable levels with a median of 229.0 pCi/L and a range of 186.0 to 430.0 pCi/L across sampled wells. These figures represent area-wide measurements, not specific household water. Homeowners considering radon treatment should obtain their own water testing to determine actual concentrations and decide on suitable treatment capacity, especially for larger or seasonal households. The Pentair Radon in Water Filter system ships ready to configure and offers a documented technology for reducing radon gas from household water supplies.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2014-06-03. 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 110ALVM aquifer (Doña Ana County): 3 results from 3 wells, median 229.0 pCi/L, range 186.0-430.0 pCi/L; none above any federal threshold
