Interpreting Water Hardness Levels and Their Relation to Faded Laundry
Linn County's groundwater aquifer 110ALVM shows water hardness from calcium and magnesium at a median of 219 mg/L, based on U.S. Geological Survey samples from 2010 to 2012. These concentrations are well within the federal non-enforceable aesthetic secondary standards, meaning they do not pose health risks or legal violations. However, such hardness levels often contribute to laundry issues like fabric fading and stiffness.
The Sample Size and Its Significance for Understanding Local Water Effects
Four samples from two wells between 33 and 40 feet deep provide this data. While the sample size is limited, these readings offer a reliable snapshot of typical groundwater quality in the area’s aquifer at that time. It is important to note that individual household water hardness can vary from these figures, so personal water testing is necessary to assess specific conditions.
Seasonal and Multi-Year Trends in Water Hardness Data
The measurements span nearly two years, from mid-2010 to mid-2012. The range—190 to 240 mg/L—shows some natural variation but remains consistently indicative of moderately hard water. This consistency suggests that water hardness is a stable factor for households relying on this groundwater source.
Changes at the Tap After Using the Autotrol Faded, Stiff Laundry System
Once equipped with the Autotrol system designed specifically for fading and stiff laundry issues, the treated water at the tap can have significantly reduced hardness effects. The system improves how water interacts with detergents and fabrics, helping maintain fabric color intensity and softness. This leads to clothes that appear brighter and feel more comfortable after washing.
How the Autotrol System Reduces Factors Contributing to Faded Laundry
The Autotrol Faded, Stiff Laundry System functions by addressing calcium and magnesium ions in the water that cause hardness. By mitigating these minerals, the system decreases buildup on fabrics and in washing machines, which otherwise can dull colors and create fabric stiffness over repeated washes. This targeted treatment helps preserve laundry appearance and texture without requiring water quality changes beyond the home.
In summary, the U.S. Geological Survey groundwater sampling provides a clear view of water hardness conditions affecting laundry quality in Linn County’s aquifer 110ALVM. While this data reflects area-wide conditions, individual water testing is necessary to determine precise local hardness. The Autotrol Faded, Stiff Laundry System ships ready to configure and offers a direct means to counteract the effects of hard water on clothes, potentially reducing faded laundry in your household.

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.
On record: U.S. Geological Survey sampling of Hardness, Ca, Mg in the 110ALVM aquifer (Linn County): 4 results from 2 wells, median 219.0 mg/L, range 190.0-240.0 mg/L; none above any federal threshold
