Laboratory Reports List Hardness Concentrations as Milligrams per Liter of Calcium and Magnesium
Water hardness is commonly reported by certified laboratories as the combined concentration of calcium (Ca) and magnesium (Mg) ions, measured in milligrams per liter (mg/L). This figure reflects the total hardness present in a water sample. In the Citrus County area, these values come from groundwater sampled in the 112NRSD aquifer.
The Number of Samples and Wells Behind Hardness Levels Is Limited—Here Are the Details
The U.S. Geological Survey collected five water hardness measurements from three separate wells in Citrus County’s 112NRSD aquifer between December 2011 and December 2012. The wells were relatively shallow, ranging from 9 to 18 feet deep. While this small sample size gives an indication of general water conditions, it does not represent every water source in the area or every commercial building’s water supply.
It Is Important to Distinguish Aesthetic Secondary Standards From Health-Based Limits for Water Hardness
Hardness measurements relate mainly to aesthetic effects such as mineral scale buildup inside pipes and on fixtures. The federal government sets secondary standards to help avoid such issues, but these are not health-based limits. In the Citrus County samples, all reported hardness results were well within federal secondary standard ranges, indicating no health risk identified from these samples.
The Sampling Depth and Well Characteristics Affect What You Can Expect From Water Hardness Readings
Sampling depth influences hardness readings. The Citrus County wells sampled were shallow, which may reflect different mineral concentrations than deeper wells or those affected by different geological conditions. Commercial operators should be aware that hardness may vary across locations and depths, so their building’s water hardness may differ from these area-wide figures.
Reading Certified Lab Test Reports for Hardness Can Clarify Your Water Profile
A certified lab test report will specifically identify the concentrations of calcium and magnesium ions, often summed as total hardness. These reports provide clear numerical results, enabling commercial operators to compare their own water against regional data like the USGS samples. Testing your building’s water supply is essential to confirm its specific hardness level before choosing treatment options.
The Range of Hardness Found in Citrus County’s 112NRSD Aquifer Falls Within Federal Secondary Standards—What This Means
The median hardness in the sampled aquifer was 61.8 mg/L, with a range from 24.3 mg/L to 174.0 mg/L. All measurements were below any federal secondary thresholds for aesthetic concerns. This means while limescale from hardness is possible, it should not be assumed that the hardness constitutes a regulatory violation or health risk based on these area-level samples alone.
Commercial operators facing limescale challenges in whole-building water systems in Citrus County should begin by obtaining a certified hardness test for their specific water source. Understanding the water hardness profile is the first step to effective treatment planning.
For managing limescale across an entire commercial property, a commercial system skid such as the 36 Steel Tanks - Triplex Unit Skid can be configured to address the scale-forming minerals documented in area groundwater. This equipment ships ready to configure as part of a commercial water treatment system designed to mitigate hardness impacts efficiently on a building-wide scale.
In summary, area-wide groundwater samples from Citrus County’s 112NRSD aquifer provide a reference for hardness levels but do not specify individual water conditions. Commercial operators should rely on direct water testing and consider appropriate treatment solutions like the 36 Steel Tanks - Triplex Unit Skid to manage limescale effectively throughout their facilities.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2012-12-12. 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 112NRSD aquifer (Citrus County): 5 results from 3 wells, median 61.8 mg/L, range 24.3-174.0 mg/L; none above any federal threshold
