If You Want to Compare Pottawatomie County Radon Measurements with Neighboring Counties

Pottawatomie County's radon data come from thirteen wells sampled in the local aquifer (310WLNG). The median radon-222 level recorded was 270.0 pCi/L, with a range from 95.0 to 3600.0 pCi/L. When comparing to nearby regions, focus on similarly scoped data sets that represent a comparable number of wells and sampling depths. Avoid interpreting a single reading as typical or assuming all local water sources match these values since geographic and geologic factors can vary markedly even within adjacent counties.

If You Want to Understand How Radon Enters Groundwater Here

Radon forms naturally underground from radioactive decay of uranium in soil and rock. In Pottawatomie County, radon migrates through fractures and porous materials and dissolves into groundwater held within the aquifer. Its presence in water depends on the surrounding geology and depth; sampled wells ranged from 102 to 320 feet. Radon does not enter the water from surface contamination but is a naturally occurring gas emanating from the earth’s crust in this area.

If You Wonder How Many Wells and Samples Inform These Results

The radon data referenced are from thirteen separate wells within the aquifer, each sampled once between August 31 and October 12, 2011. While thirteen wells provide a snapshot of this geographic area’s groundwater, this is a limited sample size that cannot capture all local variability. Homeowners should understand that individual wells may have readings above or below this area-wide range. Testing the specific household water source is necessary to determine exact radon levels on site.

If You Want to Know How Seasonal or Multi-Year Changes Appear in Local Radon Levels

This data collection occurred over a six-week period in late summer to early fall 2011. No additional long-term or seasonal data are available from this source for this aquifer. Radon levels in groundwater can fluctuate with changing water tables and temperature over longer periods, but these samples represent a single time frame. A broader testing program over multiple years and seasons would be required to observe such variation here.

If You Wonder Why Aesthetic Secondary Standards Differ from Health-Based Limits for Radon

Radon measurements have federal guidance limits intended to address health risks, but no federal threshold was exceeded in any of these area samples. Secondary standards focus on water taste, staining, or plumbing corrosion and do not apply to radon, which is a radioactive gas. Understanding the difference between aesthetic concerns and health-based criteria helps clarify the significance of detected radon levels. Detection alone does not indicate an unsafe water supply.

If You Want to Know What Terms Like Detected, Median, and Range Mean in This Context

“Detected” means radon was measured in all thirteen wells sampled; none were below the reporting limit. The median value of 270.0 pCi/L represents the middle value when all results are ordered, indicating a typical level in this dataset. The range from 95.0 to 3600.0 pCi/L shows variability among the sampled wells, reflecting differences in local geology and well depth. These statistics describe the area-wide conditions and do not predict an individual household’s water quality.

Making a decision about radon in your household water requires sampling your own well to establish actual levels. The radon measurements for Pottawatomie County aquifer 310WLNG provide useful context but are not a substitute for direct testing. If treatment is desired, the Autotrol Radon in Water Filter system ships ready to configure and provides a documented method to reduce radon content in drinking water.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2011-10-12. 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 310WLNG aquifer (Pottawatomie County): 13 results from 13 wells, median 270.0 pCi/L, range 95.0-3600.0 pCi/L; none above any federal threshold
