Is Dry Skin Always Related to Minerals in My Water Supply Here?

Many people assume that dry skin they experience is directly caused by the water’s mineral content, but this is not always the case. Dry skin can result from a variety of factors including climate, personal skin care, and indoor heating. While minerals like calcium and magnesium can influence skin feel, their presence in local groundwater does not automatically mean your water is the sole or primary cause of dry skin.

How Do Calcium and Magnesium Get Into Groundwater in St. Clair County's N500VLYRDG Aquifer?

In St. Clair County, the local N500VLYRDG aquifer supplies most groundwater. Calcium and magnesium naturally dissolve from surrounding rocks over time, gradually enriching the water as it moves through underground layers. Sampling of wells ranging around 210 feet deep shows consistent presence of these minerals, reflecting the natural geology rather than contamination or sudden influx.

What Would a Certified Lab Test Report About These Minerals?

A certified lab test measuring calcium and magnesium reports concentrations typically in milligrams per liter (mg/L). This numeric result represents the combined hardness level or separately measured concentrations of these minerals in your specific water sample. Understanding this number requires comparing it to regional ranges and knowing that detection of these minerals is normal and expected. The lab result alone cannot indicate whether your water causes skin dryness.

What Household Symptoms Suggest a Mineral-Related Dry Skin Issue?

Dry, itchy skin common during winter months is not necessarily linked to minerals in water. However, if skin dryness coincides with using water known to have higher mineral content and improves with modifying water exposure, there might be a connection. Other symptoms potentially related to mineral-rich water include feeling of soap residue or skin tightness after bathing. Conversely, symptoms like redness or rashes more often indicate other causes unrelated to water minerals.

How Should a St. Clair County Homeowner Interpret the Area's Mineral Data?

The U.S. Geological Survey has sampled wells in this area, recording calcium and magnesium concentrations from 115 to 140 mg/L, with a median of 129 mg/L. This range is typical for the region’s aquifer and falls well below federal thresholds for any health concern. This data provides a context for understanding what your own water test results might mean: variation within this range is common and does not indicate unsafe conditions.

Do These Mineral Levels Change Much Over Time?

The area data, collected over nearly a decade from 2013 to 2022, shows relatively stable levels of calcium and magnesium with limited fluctuation. This suggests that seasonal or multi-year variation in these minerals is minor. Therefore, unless unusual environmental events occur, water mineral concentrations in your well are likely consistent from year to year.

Understanding the relationship between local groundwater mineral levels and dry skin involves careful interpretation of laboratory data and awareness of other contributing factors. If dry skin persists despite knowing your water’s mineral context, testing your own water sample is necessary. For those looking to address mineral-linked skin irritation, the Fleck Dry, Itchy Skin System ships ready to configure for residential use and offers a documented approach to improving skin feel by addressing water mineral effects.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2022-06-29. 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 N500VLYRDG aquifer (St. Clair County): 4 results from 2 wells, median 129.0 mg/L, range 115.0-140.0 mg/L; none above any federal threshold
