What distinguishes radon in water from other common water quality issues?

Radon is a naturally occurring radioactive gas that can dissolve into groundwater, unlike typical contaminants such as sediments or microbial pathogens. It is odorless, colorless, and tasteless, making it different from water quality issues that affect taste, smell, or visible clarity. Radon in water primarily relates to its radioactive decay and potential airborne release when water is used in household activities.

How do sample depth, well depth, or source type change what a homeowner should expect about radon levels?

The government sampling in Hillsborough County focused on wells ranging 29 to 299 feet deep within aquifer 120FLRD. Radon levels can vary with depth as deeper wells may encounter different geological formations contributing to radon presence. Your household water source's depth and type (private well vs. public system) influence the radon range you might find, so local area data is a reference but not a direct measurement of your water.

How do public-system records differ from private-well testing in what they establish about radon?

Public water system records in Hillsborough County show no radon results above any federal threshold, based on multiple wells tested over a two-year period. These records provide a broad view of the aquifer's characteristics but do not substitute for individual household water testing. Only a certified laboratory test on your water will determine your own radon concentration accurately.

Which household fixtures, appliances, or processes are affected first and why?

Radon gas can enter your indoor air primarily during water use activities that aerate water such as showering, dishwashing, and laundry. Fixtures that release water into air, like showerheads and faucets, are the first points where radon moves from water to air. Addressing radon in water helps reduce airborne exposure within your home environment.

What do 'detected,' 'median,' and 'range' mean in the government radon sampling records for Hillsborough County?

• Detected: Radon was found in all 26 samples from 20 wells, meaning instruments measured it at some level.
• Median 890.0 pCi/L: Half of the samples had radon levels below this value, half above, reflecting a typical concentration in the sampled wells.
• Range 42.0 to 4900.0 pCi/L: The lowest and highest radon levels measured indicate variability in the aquifer but do not imply your water falls within this entire range.

What does a certified laboratory test for radon in water report and how should I read it?

A certified lab test provides a specific radon concentration level in picocuries per liter (pCi/L) for your household water sample. This number is your only reliable measure for evaluating your home's water radon risk. Understanding your result in relation to local data and federal or state guidelines helps determine if treatment steps are advisable.

What should you NOT conclude from the area's radon data?

Area-wide government sampling in Hillsborough County reveals radon presence but does not establish your household water's exact radon level or imply it is unsafe. Detection in local wells is common, but only your own water test can confirm your home's situation. If radon is a concern, you can equip your household water system with a Fleck Radon in Water Filter, which ships ready to configure to reduce radon levels effectively and help protect your indoor air quality.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-11-07. 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 (Hillsborough County): 26 results from 20 wells, median 890.0 pCi/L, range 42.0-4900.0 pCi/L; none above any federal threshold
