Sampling Details: How Extensive Is the Data Behind Radon Levels in Grant County?

Three Wells Sampled

The US Geological Survey collected groundwater samples from three separate wells in Grant County's aquifer N600CMBPLV during July 2016. These samples provide the basis for available Radon-222 measurements in this area.

Well Depth Variation

The wells ranged significantly in depth, from 335 to 1240 feet. This range reflects different groundwater sources within the aquifer but is limited in scope given only three samples.

Implications of Limited Sample Size

While these three results offer some insight into regional Radon levels, the small sample size means that local variation at individual household wells can occur and is not captured here.

Symptom Checklist: When to Consider Radon in Household Water

Unlikely to Cause Immediate Physical Symptoms

Radon in water does not cause taste, odor, or color changes detectable in the home. It also does not produce acute physical symptoms in residents.

Potential Indoor Air Impact

Radon gas released from water during showering or cooking can contribute to indoor radon levels. Testing both air and water sources is advisable if radon presence is suspected.

Water Staining or Corrosion Not Linked

Unlike other water issues, radon does not cause staining or affect plumbing materials visibly.

Understanding Standards: Aesthetic Secondary Limits Versus Health-Based Guidelines

Federal Radon Limits Apply to Water

The federal government sets health-based guidelines for Radon-222 in drinking water. None of the Grant County samples exceeded these thresholds.

Aesthetic Secondary Standards Not Relevant

Radon does not have aesthetic secondary standards since it does not affect taste, odor, or appearance, distinguishing it from other water quality concerns.

Detected Radon Is Not a Violation

Detection means the measurement instruments found Radon-222 present. This does not imply a violation of any standard or unsafe condition by itself.

Interpreting the Data: What 'Detected', 'Median', and 'Range' Indicate for Homeowners

Detected in All Samples

All three Grant County samples showed measurable Radon-222 concentrations, with none below reporting limits.

Median Value

The median concentration was 370.0 picocuries per liter (pCi/L), representing the middle value of the samples, not an average or a prediction for any specific well.

Range of Concentrations

The values ranged from 242.0 to 550.0 pCi/L, indicating variability within the few sampled wells, which may differ from individual household water.

Example for Homeowners: Reading Radon Levels in Your Context

Median as a Reference Point

The median figure of 370.0 pCi/L represents a midpoint within these three well readings, not a direct indication of your water's Radon level.

Range Shows Possible Variation

Your well water could have Radon levels at the lower, median, or upper end of the range—or outside it altogether—because individual well conditions vary.

Test Your Own Water to Know for Sure

The only way to confirm your home's water Radon concentration is through a certified laboratory analysis specific to your water source.

Final Step: Confirming Radon Levels with a Laboratory Test

To address uncertainties about your household's Radon concentration, order a Radon-222 water test performed by an accredited lab. The results will clarify whether treatment is appropriate.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2016-07-28. 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 N600CMBPLV aquifer (Grant County): 3 results from 3 wells, median 370.0 pCi/L, range 242.0-550.0 pCi/L; none above any federal threshold
