Water Sources in Calhoun County and the 124SPRT Aquifer
Water reaching homes in Calhoun County often comes from deep wells that draw from the 124SPRT aquifer. This groundwater passes through layers of soil and rock before arriving at private or community water supplies, bringing with it minerals and naturally occurring substances including radon gas. Understanding what government measurements have recorded about radon in this aquifer helps households assess their own water quality concerns.
Interpreting Radon Levels Relative to Federal Guidelines
Government sampling from two separate wells within Calhoun County's 124SPRT aquifer showed radon-222 measurements ranging from 51.0 to 216.0 picocuries per liter (pCi/L), with a median of 68.0 pCi/L. These results, collected from depths between 320 and 613 feet during 2012 to 2014, did not exceed any federal thresholds. It is important to recognize that detection of radon does not automatically imply a violation or unsafe condition. Determining the relevance of these numbers to an individual household requires testing the specific well or water source involved.
Additional Considerations for Commercial and Industrial Operators
While households focus primarily on water used for drinking and cooking, commercial or industrial water users often consider larger volumes and different exposure routes. These operators may need to assess daily water demand and radon levels with respect to process requirements and worker safety. Their questions often involve ongoing monitoring and capacity planning that differ from a residential perspective.
Observing Seasonal and Multi-Year Variation in Radon Levels
The available data from Calhoun County span nearly two years and indicate some variation in radon concentrations, from 51.0 to 216.0 pCi/L. Such fluctuations may reflect natural seasonal changes or variations in groundwater dynamics. Understanding these patterns provides context, emphasizing that radon levels can vary over time rather than remain constant.
Matching Treatment Capacity to Household Water Use
For households considering radon removal from water, gauging the daily water consumption is essential to selecting appropriate treatment solutions. Treatment systems designed for residential use, such as the C-Series Radon in Water Filter, ship ready to configure to match household water flow rates. Proper capacity alignment helps ensure effective radon reduction without unnecessary oversizing or inefficiency.
Health-Based Limits vs. Aesthetic Secondary Standards for Radon
Radon is a radioactive gas that occurs naturally in groundwater. Unlike some constituents where aesthetic secondary standards govern taste or staining, radon is regulated based on health-based limits set by federal agencies. The Calhoun County measurements, while showing radon present, remained below these health-based limits. Households should understand that exceeding an aesthetic threshold does not apply to radon, which is assessed through health benchmarks.
Meaning of 'Detected', 'Median', and 'Range' in Radon Sampling
The term 'detected' indicates that instruments measured radon in all sampled wells in the area. 'Median' refers to the middle value in the data set—in this case, 68.0 pCi/L—showing the central tendency of radon levels observed. The 'range' from 51.0 to 216.0 pCi/L expresses the spectrum of values measured, illustrating that radon levels can vary. These descriptors collectively offer insight into regional groundwater radon characteristics but do not specify the condition of any individual well or household water.
In summary, the radon data presented here reflect measurements from 2012 through 2014 collected in two wells within Calhoun County’s 124SPRT aquifer, sampled at depths between 320 and 613 feet. None of these measurements exceeded federal health-based limits. For households concerned about radon in their water, testing their own source is essential to understand their specific situation. When treatment is desired to reduce radon, the C-Series Radon in Water Filter provides a documented solution that ships ready to configure, tailored to household water usage.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-08-06. 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.
