Government groundwater sampling in Linn County, Oregon, aquifer 110ALVM, found hardness consistently detected in four samples from two wells, with a median hardness of 219.0 mg/L and a range from 190.0 to 240.0 mg/L. These samples were collected between June 2010 and June 2012. None exceeded any federal thresholds.
If you consider seasonal or multi-year variation in your industrial water supply
The data spans two years, documenting a range of hardness values in the sampled wells. This indicates some natural variability over time but no extreme shifts outside the 190 to 240 mg/L range. Industrial processes should anticipate a similar range unless their water source differs significantly. Planning for the upper range value helps avoid underestimating hardness effects.
If you compare public-system water records to private well tests
The USGS data represents wells in a specific aquifer, not public water systems or your private supply. Public water reports may show different hardness profiles due to blending or treatment. Private well tests measure your exact supply and should be obtained to confirm your water’s hardness. Area data informs what to expect, but precise measurement is essential for accurate process adjustments.
If you consider the influence of sample depth and water source type
Samples were taken from wells 33 to 40 feet deep, typical for groundwater sources in this aquifer. Industrial water sourced from different depths or surface water might exhibit different hardness characteristics. Hardness usually reflects dissolved calcium and magnesium minerals, influenced by geology and water path. Testing your specific supply at the intake point is necessary for process control.
If you need to match treatment capacity to your facility’s water demand
Effective hardness treatment depends on treating the full volume your industrial process uses daily. Hardness levels in Linn County’s aquifer indicate moderate to high mineral content, which can affect equipment and product quality if untreated. Designing or selecting a treatment system requires knowledge of both water hardness and flow rates to size equipment properly and avoid over- or under-treatment.
If you want to interpret the median and range for your facility’s water use
Using the median hardness of 219.0 mg/L with the range up to 240.0 mg/L helps estimate typical and peak conditions your process water might encounter. While your well’s hardness could differ, these figures help evaluate if hardness mitigation is warranted. For industrial-scale treatment, technologies like the 30 Steel Tanks - Triplex Unit Skid commercial system skid, designed for high capacity and continuous operation, can address this hardness range effectively.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2012-06-07. 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.
