Understanding the Twin Falls County Aquifer Water Supply
Water supplied to commercial buildings in Twin Falls County often originates from a deep aquifer, with wells reaching depths between 62 and 1090 feet. Government sampling by the U.S. Geological Survey of 44 separate wells in this area measured dissolved minerals over several months, providing a regional snapshot of water quality relevant to water heater scale concerns.
Essential Details to Record Before Seeking Treatment Advice
Obtain certified laboratory test results of your building’s water, focusing on calcium and magnesium concentrations
Note the locations and depths of wells supplying your building
Document any noticeable scale buildup or performance changes in water heaters and boilers
Record water usage volumes and flow rates across the building’s plumbing system
What Happens Over Time Without Addressing Scale Formation
Gradual mineral deposits reduce water heater efficiency and increase energy consumption
Scale buildup can cause premature equipment wear and elevated maintenance needs
Distributed scale accumulation throughout a building’s piping may impair hot water delivery consistency
Potential for increased downtime for repairs affecting business operations
Interpreting the USGS Mineral Data Record for Your Building
The median calcium and magnesium hardness concentration was 343 mg/L, with individual results ranging from 58.7 to 572 mg/L
Nearly all sampled wells detected hardness minerals, indicating these constituents are a consistent feature of the aquifer supply
None of the measurements exceeded federal regulatory thresholds, confirming no health-based violations in the area aquifer
This range of mineral content suggests a moderate to high potential for water heater scale formation in untreated water
Order of Steps to Confirm and Address Water Heater Scale
Start with a visual inspection of water heater surfaces and accessible plumbing for scale or sediment
Measure water hardness using field test kits to gauge calcium and magnesium levels
Obtain a certified laboratory analysis of water samples for accurate hardness and mineral content
Consider flow rate and water temperature data to assess scale formation risks
Evaluate options for water treatment systems designed for whole-building commercial applications
Maintenance Rhythm for the 48 Steel Tanks - Twin Unit Skid System
Routine system monitoring every three to six months to verify performance and detect mineral buildup
Periodic flushing or cleaning of tanks and piping components as recommended by product guidelines
Replacement of key system media or consumables on a lifecycle consistent with commercial demands
Review of operational parameters following major changes in water source or building water use
This checklist has guided you through the key aspects of assessing and managing water heater scale in a commercial building drawing from Twin Falls County’s aquifer. Reliable hardness data combined with targeted whole-building treatment, such as the 48 Steel Tanks - Twin Unit Skid, helps maintain equipment longevity and operational efficiency.

Source: USGS groundwater sampling. Sampled 2011-10-14. 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 (Twin Falls County): 45 results from 44 wells, median 343.0 mg/L, range 58.7-572.0 mg/L; none above any federal threshold
