How Treated Water Differs at the Tap Once the Documented Technology Is in Place

Radon Concentrations Reduce through Specialized Filtration

When a Pentair Radon in Water Filter is used, radon-222 levels in water are significantly lowered before reaching home fixtures. This reduction can lessen potential radon exposure from water usage, including inhalation during showering or other household water activities.

Treated Water Does Not Introduce Additional Radon

The filtration technology specifically targets radon, so treated water will not reintroduce radon or increase its concentration beyond what was originally present in the source water.

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

Area Sampling Shows Radon Levels Range from 4.0 to 41.0 pCi/L

United States Geological Survey groundwater samples from Franklin County’s aquifer 361MRBG, taken in 2019 from wells 198 to 225 feet deep, found radon-222 concentrations ranging from 4.0 to 41.0 picocuries per liter (pCi/L).

No Sampled Wells Exceeded Federal Radon Thresholds

None of the three sampled results surpassed the federal guideline for radon in water, indicating that radon levels at this depth and aquifer meet current regulatory expectations based on this dataset.

Detected Radon Does Not Equate to a Violation or Unsafe Water

Detection means the instruments measured radon presence; it does not indicate the water is unsafe or in violation of health standards.

The Role of Plumbing Material and Age, Separate from the Source Water

Plumbing Materials Do Not Create Radon

Radon originates from decay of uranium in the earth’s crust and is not produced or increased by plumbing materials or the household plumbing system.

Older Plumbing Does Not Affect Radon Levels

The age or condition of pipes and fixtures does not influence radon concentration in the water but can affect other water quality characteristics unrelated to radon.

What Questions a Commercial or Industrial Operator Adds That a Household Does Not

Volume and Water Usage Are Critical for Commercial Treatment

Commercial and industrial operators usually assess radon removal capacity based on larger-scale water use, requiring different system sizing and filtration rates compared to residential needs.

Regulatory Compliance May Require More Frequent Testing

Businesses might need to monitor radon levels more often and adhere to additional reporting requirements beyond those relevant for home use.

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

Initial Visual and Odor Assessments Are Insufficient for Radon

Radon is odorless and colorless; common household checks do not detect it.

Professional Laboratory Testing Is Required to Determine Radon Levels

Testing water at a certified laboratory is necessary to know actual radon concentration in a specific household's supply. Local area data provide context but do not substitute for personal water testing.

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

Deeper Wells Tend to Reflect Aquifer Radon Levels More Accurately

The USGS samples were from wells between 198 and 225 feet deep; shallower or surface water sources may have different radon profiles.

Different Source Types May Vary Radon Concentrations

Groundwater typically presents measurable radon, whereas surface water usually has lower levels; knowing your source helps anticipate potential radon presence.

These government-sampled results reflect radon measurements from Franklin County’s aquifer 361MRBG based on three wells tested in mid-2019. For specific household water radon levels, individual testing is required. The full dataset and additional information are available from the US Geological Survey monitoring location for this aquifer.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-07-09. 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 361MRBG aquifer (Franklin County): 3 results from 3 wells, median 20.0 pCi/L, range 4.0-41.0 pCi/L; none above any federal threshold
