Radon Risks in Pasco County Water: Understanding Area Testing vs. Household Needs

Which Household Fixtures and Water Uses Are Affected by Radon First and Why

Radon gas present in water tends to impact fixtures that expose water to air most, such as faucets, showerheads, and appliances that aerate water like humidifiers or ice makers. When radon escapes from water into indoor air through these uses, it contributes to indoor radon levels, which is a different concern from the radon dissolved in water itself. Appliances that use water warmed or sprayed typically see the earliest and greatest exposure to radon release, while toilets or irrigation systems involve less air contact and therefore less radon release into the household environment.

What the Range of Measured Radon Levels Means Against Federal Standards, and What It Does Not Mean

The U.S. Geological Survey’s sampling of four wells in Pasco County’s 120FLRD aquifer found radon-222 concentrations ranging from 1,300 to 9,000 picocuries per liter (pCi/L), with a median of 3,010 pCi/L. These results reflect area-wide measurements of groundwater at depths of 33 to 53 feet and do not represent the exact radon level of any individual household's well or water supply.

None of the recorded results exceeded federal thresholds for radon in water. This means the detected levels are within regulatory expectations for this region but does not imply that the radon levels in your own water supply are the same or safe without an actual test of your water. Area data cannot replace household water testing, which is necessary to determine your specific condition.

How Radon Enters Groundwater or the Distribution System in Pasco County

Radon-222 is a naturally occurring radioactive gas formed from the decay of uranium in soil and rock. In Pasco County, radon typically seeps into groundwater within the 120FLRD aquifer as it flows through uranium-containing geologic formations. This aquifer supplies many wells, so it is common for radon to be detected in water samples taken from it.

Municipal distribution systems in this region typically source water from this aquifer or from surface water treated according to federal and state standards. Radon concentrations in finished drinking water can vary but usually decrease after treatment and exposure to open air, where radon can dissipate.

How Sample Depth, Well Depth, or Source Type Changes What a Reader Should Expect

The sampled wells were between 33 and 53 feet deep, which means the radon concentrations reflect groundwater at these depths but may differ from shallower or deeper wells. Radon levels can vary significantly with depth due to geology and soil permeability.

If your household water comes from a private well at a different depth or from a municipal supply with different treatment processes, the radon level may not match the area sampling results. Testing your own water supply is essential for understanding your radon exposure.

What You Should Record Before Seeking Treatment Advice

• Depth and type of your water source (private well or municipal supply)
• Any previous water radon tests and their results
• Details about your household water system, such as point of entry and key usage points (e.g., kitchen faucet, shower)
• Existing water treatment or filtration equipment and its status

Having this information at hand allows for an informed conversation about appropriate radon treatment options tailored to your situation.

How the Fleck Radon in Water Filter Handles Radon in Household Water

The Fleck Radon in Water Filter is designed to reduce radon concentrations in household water by removing radon gas before water reaches taps and appliances. It works by passing water through media that adsorb or facilitate the release and venting of radon, lowering the radon levels that enter the home environment.

This system ships ready to configure with your existing water setup, requiring no specialized personnel to activate. Using this filter can help protect your household from radon exposure originating from water, supporting safer indoor air quality.

Trusting area sampling like that done by the U.S. Geological Survey offers valuable insight but cannot substitute for personalized water testing and treatment decisions. The Fleck Radon in Water Filter provides an effective step for households in Pasco County seeking to address radon in their water supply.

These radon data come from groundwater sampling in Pasco County’s 120FLRD aquifer conducted over several months in 2012, with full details available through the U.S. Geological Survey water data site.

Where this information comes from

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
