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

Radon concentration is reported in picocuries per liter (pCi/L)

Lab reports list radon levels measured directly from your water sample, typically indicating a numeric value such as 273 to 730 pCi/L in Centre County's aquifer 367BLFN according to government sampling.

Test results should specify sampling depth and method

Government data for this area involved wells 135 to 300 feet deep; knowing your own well’s specifics helps interpret results accurately.

Results below detection or reporting limit indicate undetectable radon

In Centre County’s recent samples, all 5 wells showed radon detected, with none below reporting limits, meaning the instruments measured radon in every tested case.

What Distinguishes Radon From the Two Problems Most Often Confused With It

Radon is a radioactive gas, invisible and odorless

Unlike many water quality issues, radon cannot be sensed through taste, smell, or appearance, which often leads to confusion with other problems such as iron staining or sulfur odors.

Radon exposure comes from inhalation and ingestion via water use

This differentiates radon from sediment or hardness problems that mainly affect plumbing and appliances.

Testing specifically for radon in water is necessary

General water tests do not detect radon; certified lab analysis focusing on radon-222 levels is required for confirmation.

What the Measured Range Means Against the Relevant Federal Standard, and What It Does Not Mean

Federal standards for radon in water guide mitigation but are not absolute safety limits

The US Environmental Protection Agency has guidelines, but none of the sampled wells in Centre County exceeded those advisory levels according to the USGS data.

Detection of radon does not indicate a legal violation or unsafe water

All five wells sampled showed radon present, yet none were above federal thresholds, meaning detection alone is not a cause for alarm under regulatory definitions.

Measured ranges help assess whether treatment capacity may need adjustment

Values from 273 to 730 pCi/L suggest variation; households whose current equipment cannot keep up may consider equipment suited to this range.

How Seasonal or Multi-Year Variation Shows in the Record

The sampling dates reflect a short mid-2017 period

All data are from July 11 to July 26, 2017, so seasonal variation over the year is not captured in this dataset.

Longer-term monitoring is advisable for accurate picture

Radon levels can fluctuate by season and over multiple years, so retesting periodically is recommended to observe any trends or sudden changes.

Why Aesthetic Secondary Standards Differ From Health-Based Limits, Applied to Radon

Radon standards focus on health-related exposure risk, not taste or appearance

This contrasts with constituents like chloride or total dissolved solids, where thresholds address taste or staining issues.

Radon’s health risks come from its radioactivity, not aesthetics

Even at levels below federal guidance, radon presence is primarily a concern for potential long-term exposure rather than water taste or clarity.

The Order in Which to Rule Things Out, from Cheapest Check to Laboratory Test

Confirm existing equipment functionality

Ensure current treatment is operating as expected, including system flow rate and maintenance status.

Conduct a certified laboratory radon test on your own water

This definitive test establishes your household’s radon concentration, as area data cannot determine your specific water quality.

Consider water source and well depth

Since government samples involved wells 135 to 300 feet deep, comparing your well depth can help relate your radon risk profile to local data.

Evaluate treatment options designed for radon reduction

If current equipment does not keep pace, treatment methods like the Pentair Radon in Water Filter system, which ships ready to configure, can address radon effectively.

What You Should NOT Conclude from Centre County Area Data

Government sampling indicates radon was detected in all nearby tested wells at levels below federal thresholds, but these results cannot define the radon concentration in your household’s water.

Detection does not signify a violation or unsafe water by itself, nor does it predict specific health risk without individual testing.

To understand your water’s radon status and appropriate treatment, arrange a certified laboratory test and assess how current equipment performance aligns with your household’s needs.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2017-07-26. 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 367BLFN aquifer (Centre County): 5 results from 5 wells, median 400.0 pCi/L, range 273.0-730.0 pCi/L; none above any federal threshold
