Radon in Bradford County: What Area Aquifer Sampling Reveals for Your Household

If you notice a persistent earthy taste or an unusual odor in your Bradford County tap water, it may be tempting to suspect radon or assume your existing equipment isn’t sufficient. Residents with water treatment systems often find their devices challenged by radon levels that can vary widely in this region. Understanding what the area's groundwater testing tells us can clarify what to expect and how best to respond.

Myth: Well Depth Doesn’t Affect Radon Levels in Water

Sampling by the U.S. Geological Survey in the Bradford County aquifer, with wells ranging from 42 to 600 feet deep, shows radon-222 present in every tested well. This means radon is widespread in the aquifer feeding local wells, but individual depth can influence levels because radon naturally emanates from rock and soil.

Myth: Plumbing Material or Age Determines Radon Concentrations at the Tap

While plumbing can influence water quality through corrosion or leaching of metals, radon being a gas dissolved in water primarily originates from the aquifer itself. The data from Bradford County focus on water before it reaches plumbing, so differences in pipe material or age do not change radon content. However, plumbing may affect aeration and how radon escapes when water is drawn.

Myth: Any Detection of Radon in Water Means it Violates a Federal Limit

The 71 samples taken from Bradford County aquifer wells all detected radon, ranging from 34.0 to 8500.0 pCi/L, with a median value of 680.0 pCi/L. None exceeded the federal standard for radon in drinking water. Detection simply means the substance was measured, not that levels are unsafe or unlawful.

Myth: ‘Detected’, ‘Median’, and ‘Range’ Are Complicated Terms Without Practical Meaning

In this context, “detected” means radon was measurable in all tested wells. The “median” is the middle value when all results are ordered, showing a typical local concentration around 680.0 pCi/L. The “range” spans the lowest to highest measurements, indicating variability but not confirming the amount in your specific well. These statistics describe the broader aquifer and help gauge what household water might contain before treatment.

Myth: Radon in Water Doesn’t Cause Issues If Left Untreated

Long-term exposure to radon dissolved in water can contribute to indoor air radon levels, especially when water is aerated during showers, cooking, or laundering. Over years without effective reduction, this can elevate health risks. Customers finding their current equipment struggling to manage radon may consider additional treatment to maintain desired water quality and safety.

Myth: Radon Risk and Treatment Needs Are the Same Regardless of Household Size or Use Patterns

Larger households or secondary properties with intermittent use might notice differences in radon levels at the tap or the efficiency of their treatment systems. Increased water use or longer periods without system operation can affect radon concentrations and system performance. Adjusting treatment capacity or supplementing existing devices may be necessary to keep pace in these situations.

Water quality data referenced here come from 71 samples of Bradford County aquifer wells taken by the U.S. Geological Survey between 2016 and 2022. They provide a broad perspective on radon occurrences in the area. For testing your own water’s radon level, a certified laboratory analysis is essential.

When existing equipment cannot keep up, the Pentair Radon in Water Filter ships ready to configure and is designed to reduce radon levels effectively, helping households maintain water quality according to their needs.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2022-07-13. 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 aquifer (Bradford County): 71 results from 71 wells, median 680.0 pCi/L, range 34.0-8500.0 pCi/L; none above any federal threshold
