Radon levels are stable year-round in Pasco County water

A frequent belief is that radon concentrations in groundwater fluctuate wildly from season to season or year to year. However, U.S. Geological Survey sampling in Pasco County’s 120FLRD aquifer between July and November 2012 shows radon was consistently detected in all four separate wells tested. Results ranged from 1,300 to 9,000 pCi/L, demonstrating some natural variation, but the data do not indicate abrupt seasonal spikes or drops during this period. This suggests radon presence in this aquifer is a persistent condition rather than a sporadic one.

Record your own water characteristics before considering treatment

Before selecting water treatment options for radon, households should note details such as their daily water usage, well depth, any prior radon measurements, and the types of water fixtures or appliances they prioritize for treatment. Since radon levels can differ between wells even in the same area, collecting current test results from your own water supply is important. These data help match equipment capacity to household demand and ensure appropriate treatment.

Public aquifer sampling differs from private well analysis

The USGS data represent samples from Pasco County’s aquifer, not individual private wells. While these area-wide data suggest general radon presence, private wells may show different concentrations depending on depth, geology, and other factors. Thus, private well testing carried out by certified laboratories provides the definitive information necessary for household treatment decisions, as public-system records are not specific to a single residence.

Radon exposure affects specific household water uses first

Radon dissolved in water becomes a concern mainly when water is used in ways that release radon gas into home air, such as showering, washing dishes, or laundering. Fixtures that aerosolize water or generate steam can increase indoor radon levels. Therefore, priority for treatment often focuses on whole-house water contact points rather than outdoor water uses or irrigation.

Detected, median, and range values clarify radon data for Pasco County

In the USGS samples, 'detected' means radon was measurable in all four wells tested; it is not an indication of a health violation. The median value of 3,010 pCi/L represents the midpoint concentration among these samples, with individual wells showing radon from 1,300 up to 9,000 pCi/L. Understanding these terms is essential since they describe the sampling results but do not define conditions in any single well.

Radon is distinct from other water contaminants often confused with it

Radon is a radioactive gas naturally occurring in groundwater, differing fundamentally from chemical contaminants or bacteria. Unlike sediment or metallic tastes sometimes mistaken for radon effects, radon does not affect water color, odor, or taste. Recognizing this distinction helps in targeting appropriate water treatment solutions.

For households in Pasco County concerned about radon levels compatible with their measured water demand, the Pentair Radon in Water Filter system ships ready to configure. This system uses proven technology to reduce radon concentration in household water supplies, addressing the specific challenge identified by public area sampling and private well testing.

Source: USGS groundwater sampling. Sampled 2012-11-19. 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 120FLRD aquifer (Pasco County): 4 results from 4 wells, median 3010.0 pCi/L, range 1300.0-9000.0 pCi/L; none above any federal threshold
