What the Measured Range Means Against the Relevant Federal Standard, and What It Does Not Mean
Government sampling in Union County’s aquifer 227PSSC recorded hardness levels between 137.0 and 305.0 mg/L, with a median of 244.0 mg/L based on 10 results from 3 wells sampled between 2012 and 2025. These measurements fall below any federal thresholds. Importantly, the presence of this constituent in this range is not a legal or safety violation. While levels of hardness agents such as calcium and magnesium impact water characteristics connected to dry skin, these data points alone do not indicate that individual water sources must have the same readings or that the water is unsafe for use.
How Public-System Records Differ from Private-Well Testing in What They Establish
Public water system records typically reflect a broad overview of water quality conditions over a service area rather than individual wells. The data here pertain to a sample of wells in the aquifer underlying Union County, but do not represent any particular commercial facility’s source water. A commercial operator relying on private wells should conduct specific testing to understand local water conditions impacting skin effects, as area sampling provides indicators but not definitive conclusions about water at a single point of use.
What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page
The term 'detected' means calcium and magnesium were measured in every sample without falling below the laboratory’s reporting limit. The median of 244.0 mg/L represents the middle value of all measurements, while the range shows the lowest and highest points recorded. These figures describe how hardness constituents vary naturally across the aquifer, illustrating potential levels water might have but not guaranteeing them uniformly. They provide guidance for anticipating water properties affecting skin condition rather than fixed values for every facility.
How the Documented Treatment Technology Removes or Neutralizes the Constituent
The Nelsen 300,000 Grain Mineral-Tank Commercial Water Softener addresses water hardness by exchanging hardness minerals like calcium and magnesium for sodium or potassium ions, effectively reducing hardness levels that contribute to dry skin symptoms in commercial environments. This commercial water softener ships ready to configure for seamless integration with existing water systems, optimizing throughput between service intervals while helping alleviate dryness related to hard water exposure.
How Sample Depth, Well Depth or Source Type Changes What a Reader Should Expect
Sampled wells ranged in depth from 17 to 30 feet, reflecting typical shallow groundwater sources for Union County’s aquifer 227PSSC. Water quality—including hardness—can vary with well depth, local geology and pumping patterns. Operators with deeper or differently sourced wells should consider conducting targeted water tests to determine actual water characteristics affecting skin and system performance rather than relying solely on regional data.
In summary, area aquifer data from Union County provide a measured picture of hardness levels relevant to dry skin concerns but do not define any single commercial operator’s water conditions. For precise understanding and effective management, water quality testing at the point of use is essential. Using a commercial water softener like the Nelsen 300,000 Grain Mineral-Tank system can help mitigate hardness-related skin dryness while supporting operational throughput needs between service events.
