Government sampling in Garland County, Arkansas, covering aquifer 364BGFK, reports groundwater hardness values measured from six wells sampled ten times between 2012 and 2023. These results provide a reliable regional context for commercial operators considering water treatment solutions for hard water concerns.
How Sample Depth, Well Depth, or Source Type Changes What to Expect
The sampled wells in Garland County ranged from 50 to 228 feet deep, reflecting typical commercial groundwater sources in the aquifer. Generally, greater well depth can influence mineral concentrations, including calcium and magnesium, which contribute to hardness. Operators should note that shallower wells might show different hardness profiles, so depth-related variation is a key factor when anticipating hardness levels for treatment planning.
How Hardness Constituent Enters Groundwater or Distribution in Garland County
Hardness in Garland County's aquifer arises naturally from the dissolution of minerals like calcium and magnesium in subterranean rock formations. This process is consistent in the region, with measured hardness attributable solely to these natural geochemical conditions rather than surface contamination. Hard water minerals enter commercial water supplies when groundwater is extracted and distributed for use.
How to Compare Garland County's Hardness Record with a Neighboring County's Record Without Overreading It
While neighboring counties may exhibit varying hardness levels due to differing geology or aquifer properties, it is important not to apply one area's data directly to another. Garland County’s median hardness in aquifer 364BGFK is 7.97 mg/L with a range from 1.12 to 160.0 mg/L. Neighboring records can inform expectations but cannot replace a dedicated hardness test of your specific water source.
A Worked Example: Interpreting Median and Range for Practical Use
For a commercial operator, the median hardness of 7.97 mg/L indicates a mid-point level of hardness across samples, while the range (1.12 to 160.0 mg/L) shows variability across wells and sampling events. This variability means some sources or times may have significantly higher hardness than others. Understanding this spread helps define the scope of treatment needed, from moderate softening to systems designed for higher hardness extremes.
What 'Detected,' 'Median,' and 'Range' Mean in This Sampling Record
- Detected: All ten samples showed measurable hardness levels; none were below detection limits.
- Median: The middle value of sample results, providing a typical hardness concentration one might expect in the area.
- Range: The spectrum from lowest to highest detected hardness, illustrating maximum variability within the tested wells.
It is important to stress that none of these samples exceeded any federal thresholds, confirming the measurements are within normal regulatory limits.
Commercial operators assessing hard water treatment requirements can advance confidently by quantifying their own source hardness on site and matching that data against Garland County’s documented range. The 30 Fiberglass Tanks - Twin Unit Skid commercial system skid ships ready to configure and delivers scalable treatment capacity suitable for varied hardness demands, providing a practical solution aligned with the documented conditions.
