1. What a Certified Laboratory Test for Radon Reports and How to Read It

When testing your household water for radon, a certified laboratory will measure radon-222 activity expressed in picocuries per liter (pCi/L). This figure is based on a specific water sample collected from your plumbing system. The lab report presents a numeric result representing radon concentration at the time of sampling. It does not provide information about radon levels at other times or locations in your home. To know your well’s radon, testing your own water is essential.

2. What the Measured Range Means Against Federal Standards, and What It Does Not Mean

U.S. Geological Survey sampling of 7 wells in Caroline County’s aquifer 122CLVR (depth 165 to 379 feet) found radon concentrations ranged from 167 to 510 pCi/L, with a median of 270 pCi/L. None of these results exceeded federal guidance thresholds. These numbers represent area measurements and cannot define the radon level in your specific well. A detection does not indicate a violation or unsafe condition; it means radon was measurable by laboratory instruments.

3. Why Aesthetic Secondary Standards Differ from Health-Based Limits, Applied to Radon

Radon in water is primarily a health concern because of its potential to release radioactive gas into indoor air. Federal guidance focuses on health-based limits, not aesthetic secondary standards—which relate to taste, staining, or odor. Radon does not have secondary standards since it does not affect water aesthetics. Understanding this distinction helps avoid confusing radon readings with water quality complaints unrelated to health.

4. How Treated Water Differs at the Tap with the Autotrol Radon in Water Filter

Using an Autotrol Radon in Water Filter treats water by reducing radon-222 before it reaches household taps. This system is designed to operate with your plumbing and uses proven technology to lower radon levels in the water supply. After treatment, water entering the home contains less radon, reducing the risk of indoor air contamination from released radioactive gas during typical water use activities like showering and cooking.

5. How Public-System Records Differ From Private-Well Testing in What They Establish

Government data for Caroline County aquifer 122CLVR reflect area-wide sampling from multiple wells, providing a general overview of expected radon levels. These records do not reflect private-well conditions, which depend on local geology, well depth, and construction. Individual well testing is required to understand your household water radon concentration. Public data serve as a baseline reference, not a substitute for private testing.

6. How Many Samples and Wells Stand Behind the Figures, and What a Small Sample Means

The area’s radon information is based on 7 samples from 7 wells collected over two months in 2010. While offering a snapshot of radon presence in the aquifer, this modest sample size means results may not capture all variability. New drilling, seasonal changes, or well modifications could produce different radon levels in a given private well. Testing your water provides the most accurate current information.

What You Should NOT Conclude From Area Data

Area measurements do not reveal your household’s exact radon level. A detectable radon concentration in the Caroline County aquifer does not equate to a health violation. Private well testing is necessary to know your water’s condition and the effectiveness of any treatment like the Autotrol Radon in Water Filter.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2010-08-25. 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 122CLVR aquifer (Caroline County): 7 results from 7 wells, median 270.0 pCi/L, range 167.0-510.0 pCi/L; none above any federal threshold
