Many households assume that dry skin from tap water directly reflects a specific mineral level, but that’s an oversimplification. Understanding Hillsborough County's water profile can help clarify which water conditions might contribute to dryness and how to approach treatment.

If you observe dry skin and want a clear starting point

The U.S. Geological Survey tested groundwater from 11 wells in the Hillsborough County aquifer 112NRSD between 2010 and 2012. These samples showed calcium and magnesium concentrations—the minerals that determine water hardness—ranged from 7.39 mg/L to 231.0 mg/L, with a median of 34.95 mg/L. While this indicates varying hardness levels in local wells, none of these results exceeded any federal regulatory limits.

For a homeowner assessing dry skin causes, this means your well or municipal supply likely falls somewhere within this broad range. However, the precise hardness of your water depends on your specific source and requires testing to confirm.

If you begin by ruling out common factors before seeking treatment

• Check household water use and temperature, as hot water tends to dry skin more quickly.
• Try moisturizing routines independent of water adjustments to see if dryness improves.
• Conduct a water hardness test for your own source to know actual calcium and magnesium levels.
• Consider professional water analysis for a full profile if basic testing is inconclusive.

If you plan to seek informed advice for water treatment

Record your water test results, including calcium and magnesium concentrations, water source type (well or public supply), and any skin observations over time. This data helps in evaluating which technical water conditioning methods might be appropriate for your household.

If you want to understand what the federal standards imply about these results

The samples from Hillsborough County showed no federal limit exceedances for calcium or magnesium, indicating these levels are within regulatory expectations. Importantly, detecting hardness minerals is common and not a safety concern, though higher concentrations can influence water feel and potentially contribute to skin dryness.

This federal context helps distinguish aesthetic water quality from health-based water quality concerns.

If you compare public system water data with private well testing

Public system records provide broad regional data but might not reflect the variability of private wells. The median and range described come from wells 14 to 64 feet deep sampled around the county, offering a useful reference but not a substitute for personal well analysis.

If you want to grasp the meaning of ‘detected,’ ‘median,’ and ‘range’ in these tests

• Detected means the mineral was measured by instruments in all samples.
• Median is the middle value when all results are ordered, here 34.95 mg/L calcium plus magnesium.
• Range shows the lowest and highest results found, from 7.39 mg/L to 231.0 mg/L.

These statistics do not indicate safety or health conditions but provide a descriptive snapshot of water hardness variation in the aquifer.

For households seeking relief from dry skin linked to these water conditions, the Fleck Dry, Itchy Skin System offers a direct-purchase solution that ships ready to configure for your needs. It targets factors associated with water hardness that can affect skin comfort.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-11-14. 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 Hardness, Ca, Mg in the 112NRSD aquifer (Hillsborough County): 12 results from 11 wells, median 34.95 mg/L, range 7.39-231.0 mg/L; none above any federal threshold
