Understanding Detected, Median, and Range in Lee County Aquifer 230SDMR Sampling

Detected Means Measured Presence, Not a Violation or Unsafe Level

The USGS sampled 53 wells in Lee County's aquifer 230SDMR, detecting calcium and magnesium in every well. Detection simply confirms these minerals are present. According to the data, none of these results exceeded federal health thresholds, so detection should not be confused with a safety concern.

Median Indicates Middle Value Among Samples

The median hardness from these 53 wells was 107.0 mg/L, meaning half the samples measured above this value and half below. This provides a useful benchmark for understanding typical mineral levels in the area diluted across different wells.

Range Shows Extent of Variation Observed

The recorded hardness values ranged from a low of 6.14 to a high of 481.0 mg/L, reflecting variability likely influenced by well depth, location, and geology. Such a range suggests some homes may have water with very low mineral content while others have much higher levels.

How Sample Depth and Well Characteristics Affect Household Water Quality Expectations

Wells Sampled Were Between 60 and 370 Feet Deep

Depth influences mineral concentrations. Deeper wells may access different water strata with distinct composition. Homeowners with shallower or deeper wells should consider that their water might vary from the median accordingly.

Aquifer Variation Means Household Results Can Differ

Because aquifer 230SDMR covers a broad area, each household’s water hardness depends on groundwater path and rock contact. The sampled wells provide area context but cannot precisely predict one home’s water.

Differences Between Public System Water Records and Private Well Testing

Public Water Systems Regularly Test and Report Water Quality

Lee County’s municipal water suppliers test hardness among other parameters. Their reports reflect distributed water but may differ from private well water due to source and treatment differences.

Private Wells Require Individual Laboratory Testing

For spot-free dishes decisions, a household well test measuring calcium and magnesium concentrations is essential. Area data informs general expectations but does not replace specific analysis.

Additional Considerations for Commercial or Industrial Water Users

Higher Volume Use and Equipment Sensitivity Demand Precise Measurements

Businesses must often meet stricter operational standards. They should obtain comprehensive water profiles beyond household needs to assess impact on glassware and appliances.

Commercial Operators Should Also Monitor Water Quality Changes Over Time

Industrial water sources might fluctuate seasonally, requiring ongoing assessment for spot prevention tailored to equipment and use level.

Origin of Calcium and Magnesium in Lee County Groundwater

Minerals Enter Water Through Contact With Aquifer Rock Materials

Calcium and magnesium naturally dissolve from minerals in rock strata as groundwater flows. Variations in geology and water residence time create the wide hardness range observed.

System Water May Also Contain These Elements From Surface Sources

Though primarily groundwater-derived, some surface contributions can influence overall mineral content in distribution systems.

Stepwise Approach to Diagnosing Spot Formation Before Laboratory Testing

Check Household Dishwasher Settings and Detergent

Spotting can originate from detergent type and rinse settings independent of water quality.

Observe Spot Patterns and Frequency

Consistent spot formation across cycles suggests mineral-related causes, prompting water testing.

Order a Laboratory Test for Calcium and Magnesium Concentrations

This single test will determine if water hardness levels correspond with spot formation tendencies in Lee County. Results near or above the area median of 107.0 mg/L indicate potential for spots caused by dissolved minerals.

Should hardness be identified as the cause, the Fleck Spotty Dishes & Glassware System ships ready to configure to address spot formation effectively, providing targeted treatment to improve dish and glassware appearance.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-08-09. 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.
