This week you need to decide whether your household should consider salt-free water softening to manage water hardness issues.
What Happens When Hard Water Is Left Untreated for Years
Mineral Build-Up in Appliances and Pipes
Hardness minerals like calcium and magnesium can gradually accumulate inside water-using appliances and plumbing, potentially reducing efficiency over time.
Scaling on Fixtures and Surfaces
Deposits may appear as white or cloudy films on faucets, showerheads, and sinks, which can be inconvenient to clean and affect appearance.
Possible Impact on Soap and Detergent Performance
Hard water minerals can interfere with the effectiveness of soaps and detergents, leading to the need for more product or extra rinsing.
How to Compare Thurston County's Hardness Data Without Overreading It
Recognize Variation Within Regional Averages
USGS groundwater sampling in Thurston County’s aquifer 112GLCV shows median hardness of 48.0 mg/L, within a range of 44.3 to 77.0 mg/L. These figures reflect several wells sampled between 2010 and 2016, not any individual household’s water.
Consider Neighboring Counties’ Data for Context
Comparing to a nearby county’s hardness values can provide perspective but should not lead to assumptions about your own water's specific hardness, which only testing can confirm.
Understanding the Sampling Basis Behind These Figures
Number of Wells and Samples Behind the Data
The USGS dataset includes five hardness results from three different wells, each sampled multiple times between 2010 and 2016, from depths of 51 to 72 feet.
Implications of a Small Sample Size
With limited samples, the figures provide a general overview of the regional aquifer water quality but cannot precisely characterize any single well’s hardness.
Distinguishing Hardness from Other Common Water Characteristics
Hardness Versus Iron or Manganese Stains
Hardness is related to calcium and magnesium minerals causing scale, whereas iron and manganese cause discoloration or reddish stains, which are different issues.
Hardness Versus Total Dissolved Solids (TDS)
TDS measures all dissolved substances, not just hardness minerals, and influences taste and corrosivity but is not a direct measure of hardness.
How Treated Water Differs When Using a Salt-Free Scale Control System at the Tap
Reduction of Scale Buildup Without Adding Salt
The C-Series Salt-Free Scale Control System conditions water to help prevent scale formation by altering how hardness minerals behave, without using salt or exchanging ions.
Maintenance of Mineral Content
Unlike traditional softeners, the system does not remove calcium or magnesium, preserving water’s natural mineral content and supporting a salt-free lifestyle.
Convenience and Compatibility
The system ships ready to configure for household use, fitting into existing water lines without requiring salt replenishment.
The USGS groundwater data referenced applies to samples from three wells in Thurston County’s aquifer 112GLCV collected from 2010 through 2016. For direct access to detailed figures and sampling methods, visit the USGS website at waterdata.usgs.gov.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-13. 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 112GLCV aquifer (Thurston County): 5 results from 3 wells, median 48.0 mg/L, range 44.3-77.0 mg/L; none above any federal threshold
