Sample Data and Scope Behind Reported Water Quality Figures

Number of Samples and Wells Represent the Data

The U.S. Geological Survey collected 129 groundwater samples from 16 wells in the Washington County aquifer area between March 2010 and April 2025. These wells range in depth from 75 to 1000 feet, providing a broad data set for the region's water quality. However, this sample, while extensive, represents regional conditions and may not reflect the specifics of any one well.

Implications of a Regional Sample Size

Although 129 samples form a solid basis for understanding area-wide groundwater characteristics, the variation within the data—from as low as 134 mg/L up to 2440 mg/L—indicates substantial variability. Smaller or fewer samples would increase uncertainty, but this collection allows for identifying common conditions that impact commercial laundry operations.

Differences Between Public Records and Private Testing Results

Public Sampling Reflects Regional Trends, Not Individual Wells

The government’s groundwater data derives from testing multiple wells across the county but does not establish the condition of any specific well or tap water source. Private well owners or commercial operators need individual water testing to know their exact water characteristics.

Records Show No Federal Threshold Exceedances

This regional dataset from Washington County aquifer wells shows that none of the hardness levels measured exceeded federal safety thresholds. It is important to note that detection at any level does not indicate a violation or unsafe condition—hardness is more commonly tied to aesthetic and operational concerns like laundry fading rather than health risks.

Comparing Washington County Aquifer Data with Neighboring Areas

Avoid Overinterpreting Regional Differences

While neighboring counties may show differing median or range values in similar constituents, such differences arise from natural geological and hydrological variation rather than changes in safety or basic suitability of water for commercial use. Use careful comparison to inform treatment class decisions, avoiding assumptions about individual water sources based on nearby data.

Understanding Key Terms in the Sampling Record

'Detected' Indicates Measurement, Not a Problem

All 129 samples showed measurable levels of calcium and magnesium hardness; none fell below reporting limits. This means the instruments detected these constituents consistently in the aquifer samples.

Median and Range Explain Data Distribution

The median hardness concentration across the wells was 312 mg/L, the midpoint of the dataset showing typical conditions. The range extended from 134 mg/L to 2440 mg/L, illustrating significant variability—important when considering commercial treatment needs for faded laundry outcomes.

Information to Gather Before Selecting Treatment Solutions

Obtain Specific Water Tests for Your Facility

To make an informed choice about treatment classes that address faded laundry, collect laboratory water test reports listing hardness components from your own operational supply. This information ensures treatment matches actual water conditions rather than relying solely on area data.

Document Usage Patterns and Commercial Laundry Scale

Record the volume of water used daily and any seasonal or operational fluctuations. This data supports selecting a treatment system appropriately sized for your facility’s needs.

Note Any Other Water Quality Factors Impacting Laundry

List observations or test results for factors such as iron or manganese (if present), which can affect laundry appearance and treatment strategy.

Summary: This page outlined the scope and meaning of Washington County aquifer groundwater sampling related to water hardness, clarifying what regional data can and cannot establish for commercial laundry operations facing faded laundry problems. Before deciding on treatment classes, individual facility water testing and operational details are essential. The 42 Steel Tanks - Twin Unit Skid commercial system skid ships ready to configure and can address hardness conditions identified through precise assessment.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2025-04-23. 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 aquifer (Washington County): 129 results from 16 wells, median 312.0 mg/L, range 134.0-2440.0 mg/L; none above any federal threshold
