The U.S. Geological Survey’s sampling of groundwater from Pasquotank County, specifically within aquifer 110QRNR, measured calcium and magnesium levels with a median total hardness of 15.25 mg/L in ten samples from one well over 2015 to 2017. While minerals that contribute to hardness were consistently detected, none of the results exceeded federal thresholds for hardness. This data provides a regional understanding, not a specific profile of any one facility’s water.
How the Documented Treatment Technology Addresses Mineral Content
The 48 Fiberglass Tanks-Single Unit Skid f commercial system skids are designed to manage minerals like calcium and magnesium found in this aquifer. By processing water to reduce or neutralize these minerals, the system helps prevent mineral deposits that can cause spotting on dishes, a common challenge in commercial dishwashing operations.
Which Commercial Fixtures and Processes Experience Mineral Impact First
Hardness minerals like calcium and magnesium tend to accumulate on dishwasher surfaces and glassware, leading to visible spotting and film. In commercial kitchens, dishwashers are among the first to show these effects because of high water volume use and short cycle times that can leave mineral residue if not addressed.
What Seasonal and Multi-Year Water Hardness Data Shows
The sampling dates span from July 2015 through March 2017 and indicate a hardness range from 13.2 to 30.3 mg/L. This variation reflects natural fluctuations in aquifer mineral levels over time but, importantly, stays below any federal hardness threshold, suggesting relatively stable mineral presence during this period.
Understanding the Sample Size and Its Impact on Data Confidence
The data set consists of 10 samples from a single well, which limits the breadth of regional hardness characterization. A small sample count means individual facilities could experience different hardness levels, making localized testing essential to determine specific water conditions.
Steps to Confirm Your Facility’s Water Profile
- Start with basic water quality checks such as hardness test strips or handheld meters for an initial assessment.
- Proceed to send water samples to a certified laboratory to precisely quantify calcium and magnesium concentrations.
- Use the results to evaluate whether a commercial system skid like the 48 Fiberglass Tanks-Single Unit Skid f addresses your spot-free dish requirements effectively.
It is important to note what these area data do not confirm: they do not guarantee the hardness level or spotting potential of your own water supply. Only direct testing of your water can establish the mineral profile affecting your dishwashing processes. The regional government data serves as a valuable guide to what might be expected but not a definitive measure of individual facility conditions.
