This week, you must decide which type of radon water treatment equipment best fits your household’s needs in Kent County, Delaware. Radon, a naturally occurring radioactive gas, can dissolve into groundwater from the surrounding geology and enter your home through your water supply. Selecting the right technology depends on understanding regional data, your household’s water use, and how radon affects household fixtures.
If You Compare Public System Records with Private Well Testing, Understand What They Show
Records from public water systems often provide broad compliance and water quality status but usually do not reflect specific private well conditions. In Kent County’s aquifer 125RCCS, the U.S. Geological Survey sampled 12 wells, each 180 to 380 feet deep, between July and August 2015. They found radon-222 concentrations ranging from 126.0 to 640.0 pCi/L, with a median of 400.0 pCi/L. Every well had a detectable radon level, but none surpassed federal thresholds that apply to public water systems.
These results represent regional groundwater conditions rather than your specific well. Only a certified laboratory test from your residence’s water can determine your exact radon level. This distinction matters because equipment decisions should be based on your own water quality, not area samples alone.
If You Review Daily Household Water Use, Consider Treatment Capacity Requirements
Radon water treatment equipment capacity should match your household’s typical daily water demand. Larger households or those using more water daily will require a system that handles higher volumes without reducing flow or effectiveness. Understanding your average water use helps to find a treatment option that ensures all consumed water receives proper radon reduction.
The documented technology addressing this need is the Autotrol Radon in Water Filter, which ships ready to configure and can be selected based on your household’s flow rate and volume. Matching equipment capacity avoids overburdening the system or unnecessary oversizing.
If You Consider Which Fixtures and Appliances Radon Affects First, Understand the Water Pathway
Radon dissolved in water primarily impacts fixtures and appliances that use untreated groundwater directly, such as kitchen taps, drinking fountains, and showers. It may be released into the air during water use, increasing indoor radon levels. Appliances that use filtered or treated water, like refrigerators or ice makers, also depend on proper radon reduction equipment to minimize exposure.
Prioritizing treatment for drinking and cooking water points typically guides equipment configuration, ensuring the highest exposure pathways are addressed first.
If You Obtain a Certified Laboratory Radon Test for Your Water, Know What the Report Shows
A certified lab test identifies radon concentration in water measured in picocuries per liter (pCi/L). The report provides your well’s specific radon level, which may differ significantly from regional data. This test is the only reliable way to inform your treatment choice. It does not label detected radon as unsafe but provides a measurement to guide technology selection in line with federal recommendations.
If You Review Seasonal or Multi-Year Variation in Radon Levels, Observe the Patterns in Kent County
The U.S. Geological Survey samples within Kent County’s aquifer 125RCCS indicate radon levels ranging from 126.0 to 640.0 pCi/L over a one-and-a-half month span in summer 2015. Radon concentrations can vary over time due to changes in groundwater flow, temperature, and local geology. Understanding these temporal variations helps gauge when retesting might be necessary, especially if your household water use or well conditions change.
If You Leave Radon Untreated in Water for Years, Be Aware of Implications Without Alarm
Leaving radon in your water untreated can result in ongoing low-level exposure when using water for drinking, cooking, or bathing. Radon in water can contribute to indoor air radon levels when released during water use. While not an immediate acute hazard, sustained radon exposure over long periods may increase health risks. Treatment reduces radon levels to minimize this exposure.
Consider What These Area Measurements Do Not Say
Do not assume your household’s water contains the same radon concentrations as those found in Kent County regional samples. Area measurements do not establish individual well conditions or health risk thresholds. They do not indicate any violation of federal limits. To make an informed decision, test your own water through a certified laboratory and evaluate treatment options accordingly. The Autotrol Radon in Water Filter offers a documented technology to reduce radon based on your home’s specific needs.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2015-08-20. 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 125RCCS aquifer (Kent County): 12 results from 12 wells, median 400.0 pCi/L, range 126.0-640.0 pCi/L; none above any federal threshold
