Starting with Simple Checks Before Laboratory Confirmation
When you first consider radon as a potential water issue, begin with straightforward observations and general information about your water source. Since radon is a naturally occurring gas that can dissolve into groundwater, understanding if your water comes from a deep well tapping into aquifer 124CSLH in Beaufort County is a helpful starting point. If your water system is municipal, reviewing local water quality reports can provide initial insight. However, these sources do not replace specific lab testing of your own water, which is necessary to understand your household’s radon levels accurately.
What a Certified Laboratory Test Reports and How to Interpret It
A certified laboratory measuring radon-222 in water typically provides results expressed in picocuries per liter (pCi/L). The report lists the measured radon concentration, the detection limits of their instruments, and sometimes reference levels for comparison. In Beaufort County's aquifer 124CSLH, U.S. Geological Survey sampling in 2013 recorded radon concentrations from 38.0 to 253.0 pCi/L, with a median of 164.5 pCi/L in four wells sampled between 202 and 323 feet deep. None of these results exceeded federal action levels, which means the measurements are within regulatory allowances rather than indicating a health violation. Your lab report would give your specific value, which you can compare thoughtfully to these area data but cannot assume identical conditions.
Assessing Treatment Capacity Relative to Household Water Use
Radon treatment in water depends on the volume of water your household uses daily. Radon in water can be reduced effectively by appropriate point-of-entry systems designed to handle typical residential demand. To determine if a treatment system suits your home, consider your average daily water use in gallons or liters. Treatment devices like the C-Series Radon in Water Filter ship ready to configure for residential flow rates. Selecting a system that matches your water consumption ensures efficient radon reduction without overburdening the equipment or undertreating your supply.
Understanding 'Detected', 'Median', and 'Range' in Regional Sampling Records
In the context of Beaufort County's aquifer measurements, 'detected' means radon was measured above the laboratory's reporting limit in every sample taken, confirming its presence in groundwater at these depths. The 'median' value of 164.5 pCi/L represents the middle point of the four samples, showing a typical regional concentration, while the 'range' between 38.0 and 253.0 pCi/L shows variability in radon levels from well to well. These figures describe what radon concentrations have been found in this aquifer section and do not directly indicate your water’s specific radon content without individual testing.
Differences Between Public-System Records and Private-Well Testing
Public water system records usually provide averaged or monitored radon levels for their distribution but do not replace a private well test, which reflects the unique conditions of your water source. Municipal supplies in Beaufort County generally must meet federal standards and report testing results publicly; these records often show no health-based violations for radon in water. Private wells drawing from aquifer 124CSLH can vary in radon levels even within short distances due to geological differences. Consequently, a private well owner should obtain a certified lab analysis specific to their well to determine precise radon content and decide on treatment accordingly.
In summary, the U.S. Geological Survey’s 2013 groundwater sampling in Beaufort County aquifer 124CSLH found radon present at variable but federally acceptable levels in four deep wells. To know your household’s radon level, test your water with a certified lab. If treatment is needed, systems like the C-Series Radon in Water Filter are designed for residential capacities and provide a documented solution.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-09-24. 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 124CSLH aquifer (Beaufort County): 4 results from 4 wells, median 164.5 pCi/L, range 38.0-253.0 pCi/L; none above any federal threshold
