When managing water for an entire commercial building, especially in Pottawatomie County, Oklahoma, one common observation at dishwashing stations is the presence of spots on cleaned dishes. This can be a sign of dissolved minerals commonly found in groundwater from local aquifers, which influence rinse water quality and thus the appearance of dishes after washing.
How Commercial System Skids Address Mineral Effects in Entire Buildings
Commercial System Skids such as the 36 Steel Tanks - Triplex Unit Skid are designed to treat water on a building-wide scale rather than at a single outlet. These systems work by conditioning water to reduce the minerals that cause spotting and film buildup on dishes throughout the building’s water supply. By processing the water centrally, such a unit can maintain consistent water quality at all dishwashing and rinse points, ensuring dishes come out clear and spot-free.
Effect of Well Depth on Expectation of Water Mineral Content
The samples from wells 110 to 200 feet deep in the aquifer supplying Pottawatomie County show a range of dissolved minerals. Deeper wells often draw water from layers with varied mineral concentrations, affecting the calcium and magnesium levels contributing to spotting. Understanding that these samples come from substantial depths sets expectations for the dissolved solids impacting rinse water quality in commercial buildings.
Sample Size and Variability Considerations in Aquifer Mineral Content
The data set includes six samples from six separate wells taken between 2011 and 2013. While this number provides a useful snapshot of area water characteristics, it is a limited sample. Mineral concentrations can vary significantly across wells and over time. Thus, the figures represent a regional overview rather than a definitive value for any particular commercial building's water supply in the county.
Comparing Public System Records and Private Well Testing
Public water systems in Pottawatomie County have separate testing records and regulatory standards compared to private wells. Records for the aquifer show no federal health-based violations for calcium or magnesium. However, these public system records do not speak to every building’s supply. For a commercial building using private well water, conducting an individual water test is essential to determine the actual mineral content affecting dish quality.
Distinguishing Aesthetic Secondary Standards from Health-Based Limits
Calcium and magnesium minerals contribute to water hardness, which affects the appearance of dishes but are subject only to aesthetic secondary standards, not health-based limits. This means that even if mineral levels cause spotting or film, they do not indicate a health risk. The government’s median reading of 76.5 mg/L in the region is below any established health limit, reflecting typical mineral presence rather than danger.
Interpreting the Median and Range of Mineral Data for Commercial Settings
The median value of 76.5 mg/L represents the midpoint of six sampled wells, with a range from 25.8 to 190.0 mg/L. For a commercial operator, this means some water sources in the area may have relatively low mineral levels, while others are notably higher. Spot-free dishwashing performance will vary accordingly, and treating the entire building’s water with an appropriate commercial system skid can mitigate the effects of this range.
For commercial buildings in Pottawatomie County seeking consistent spot-free dishes, equipping the water supply with a 36 Steel Tanks - Triplex Unit Skid offers a scalable solution. This commercial system skid ships ready to configure for treating the whole building’s water, reducing mineral-related spotting and improving rinse results across all dishwashing stations.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-03-13. 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 317GBWG aquifer (Pottawatomie County): 6 results from 6 wells, median 76.5 mg/L, range 25.8-190.0 mg/L; none above any federal threshold
