Are you managing a commercial building in Pima County and noticing dry skin issues among occupants? Dry skin can sometimes be linked to water quality characteristics, especially when treating water at the building level rather than at individual taps. Understanding local water data can help you decide on the right approach to address this concern.
If you need to maintain a large-scale water treatment system regularly
Commercial System Skids, such as the 20 Steel Tanks - Twin Unit Skid, ship ready to configure for whole-building water treatment. Their maintenance rhythm typically involves periodically checking tank levels, replenishing treatment media as needed, and routine cleaning cycles, which for commercial scale units, usually occurs every few months depending on water usage and quality. Scheduling maintenance consistently ensures optimal performance and long-term reliability for your water system.
If you are wondering what the range of measured water hardness means against federal standards
Government sampling in the Pima County aquifer found hardness levels—measured by calcium and magnesium content—in 15 samples from 13 wells ranging from 12.9 to 1170.0 mg/L, with a median of 143.0 mg/L. None of these results exceeded any federal threshold. This means the detected hardness does not represent a violation or a health safety concern. Instead, hardness at these levels can contribute to dry skin sensations for some people, particularly in commercial or multi-outlet water uses. However, the presence of hardness minerals detected here does not automatically imply harmful water for your building’s occupants.
If you operate a large commercial building versus a smaller or seasonal property
When treating an entire commercial building rather than a single outlet, system capacity and durability are critical factors. Larger water volumes demand equipment that can handle sustained flow rates and regeneration cycles appropriate for the facility's water use. Seasonal properties or smaller buildings may not require the same scale or maintenance intensity. Commercial System Skids, like the 20 Steel Tanks - Twin Unit Skid, are designed to meet larger flow and treatment demands efficiently for whole-building applications.
If you want to understand what terms like 'detected,' 'median,' and 'range' indicate in the sampling record
'Detected' means the measurement instruments registered the presence of hardness minerals in every sample from this aquifer area; none fell below the reporting limit. The 'median' value is the middle figure of all results (143.0 mg/L), representing a typical hardness concentration. The 'range' (12.9 to 1170.0 mg/L) shows the variability found among sampled wells. This variability is normal in groundwater systems due to depth and geological factors. These terms do not identify your building’s specific water quality, which requires on-site testing.
If you consider how many samples and wells support this data and what a limited sample means
The data derives from 15 hardness measurements collected between January 2016 and February 2024 across 13 wells ranging in depth from 37 to 687 feet. While this sampling provides a meaningful overview of the Pima County aquifer’s range, a limited number of wells also means local variations can exist. Therefore, understanding your building’s precise water characteristics calls for direct testing of your supply. This broader sampling helps inform decisions but does not replace site-specific analysis.
This water quality record focuses on aquifer data for Pima County and is sourced from U.S. Geological Survey groundwater sampling data available online. For tailored treatment addressing dry skin concerns throughout your commercial building, equipment such as the 20 Steel Tanks - Twin Unit Skid offers a scalable, maintainable solution designed for commercial water systems.
