Interpreting Detection, Median, and Range in Your Area's Water Quality Data
Detected means measured but not a safety violation
In Moore County's aquifer 121OGLL, calcium and magnesium were consistently detected in all sampled wells between 2012 and 2021 with no results below reporting limits. Detection indicates these minerals are present but does not imply any health risk or violation.
Median indicates the middle value of measurements
The median hardness concentration measured was 221.0 mg/L, showing a typical mineral level in groundwater for this aquifer.
Range shows variation across sample points
Measured levels ranged from 203.0 to 244.0 mg/L, reflecting natural variation in underground water sources within Moore County.
How Source Depth and Well Conditions Affect Expected Water Characteristics
Sampled wells are deep, influencing mineral content
The sampled wells range from 450 to 635 feet deep, which generally means water quality is stable but mineral-rich as it passes through underground rock formations.
Well depth can lead to higher calcium and magnesium presence
Deeper wells often draw from older groundwater that has had more time to dissolve minerals like calcium and magnesium, contributing to hardness.
Source type (aquifer vs surface) guides expectations for mineral content
Water from aquifers like 121OGLL typically contains dissolved minerals affecting hardness but not necessarily safety.
Distinguishing Aesthetic Secondary Standards from Health-Based Limits
Secondary standards address taste, appearance, and texture, not health
Calcium and magnesium contribute to water hardness and may affect skin feel but are regulated for aesthetic reasons, not for health risks.
No federal threshold exceeded in Moore County sampling
The USGS data confirms no measurements surpassed federal limits, confirming water quality meets safety standards.
Understanding these standards helps target dry skin causes correctly
Knowing the difference prevents misinterpreting hardness as harmful while acknowledging its role in skin irritation.
Fixtures and Uses Most Impacted by Water Hardness in Households
Bathing fixtures experience first noticeable effects
Showers and baths often reveal dryness or itching caused by minerals affecting skin moisture retention.
Skin contact with hard water can increase dryness symptoms
Calcium and magnesium present can reduce skin softness and cause discomfort during and after washing.
Appliances and other water uses feel effects later
Though dishwashers and washing machines see hardness impact, skin symptoms manifest primarily at points of direct contact with water.
Federal Limits Compared with Measured Mineral Ranges in Moore County
Measured calcium and magnesium levels are well within safe limits
All samples were below thresholds set by federal secondary standards, indicating no regulatory concern.
Range variation signals natural groundwater differences, not problems
Variability between 203.0 and 244.0 mg/L is normal for the aquifer and does not indicate drinking water safety issues.
Data supports focusing on managing hardness to relieve skin dryness
While safe, these mineral levels can contribute to dry skin symptoms, prompting consideration of treatment options for comfort.
Household Symptoms Related to Hard Water and Dry Skin
Itchy or flaky skin after bathing
Skin dryness and itchiness following water exposure often signal mineral effects from hardness.
Symptoms that do not indicate water hardness
Persistent skin conditions unrelated to water contact or involving rash or inflammation should seek medical advice beyond water treatment.
Testing is required to confirm your household water mineral content
Because regional data cannot specify your home’s water hardness exactly, individual testing is the only way to determine your water’s specific mineral makeup.
For households in Moore County experiencing dry skin when their current system cannot keep up, the Autotrol Dry, Itchy Skin System ships ready to configure and offers a direct approach to managing mineral effects that contribute to this condition.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2021-05-25. 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 121OGLL aquifer (Moore County): 11 results from 7 wells, median 221.0 mg/L, range 203.0-244.0 mg/L; none above any federal threshold
