Start by Eliminating Obvious Causes Before Lab Testing
Check your water’s effects on plumbing and fixtures
Visible staining, scale buildup, or water taste can indicate iron and hardness presence but cannot establish exact levels.
Review area data as a general guide
The U.S. Geological Survey sampled groundwater from seven wells in Shawano County’s 100SDGV aquifer from 2011 to 2024, finding hardness measurements (from calcium and magnesium) ranging from 48.9 to 289.0 mg/L with a median of 204.5 mg/L.
Understand depth variation
Sampled wells ranged from 10 to 240 feet deep; water quality can vary with well depth, so local conditions may differ.
Order a detailed laboratory test for your water
This is the only way to accurately determine your household water's iron and hardness concentrations.
Interpret Aesthetic Secondary Standards Versus Health-Based Guidelines
Hardness thresholds primarily address taste and scale formation
The measured hardness values fall below any federal health-based limits but may exceed aesthetic secondary standards affecting household use.
Iron presence is common and not inherently unsafe
Iron detected in water affects color and taste but is regulated mainly for nuisance rather than health risk.
Differentiating Iron and Hardness from Commonly Confused Water Issues
Iron causes reddish staining unlike other minerals
Unlike manganese or sulfur odors, iron typically leaves rust-colored stains.
Hardness relates to mineral concentration, separate from water acidity
Hard water results from calcium and magnesium, distinct from pH or corrosivity issues.
Consequences of Neglecting Iron and Hardness Over Time
Scale buildup can reduce plumbing efficiency and lifespan
Hardness minerals accumulate inside pipes and appliances, potentially increasing energy use and maintenance.
Iron deposits may discolor laundry and fixtures
Rust-colored stains on clothes and surfaces may become more persistent without treatment.
How to Read Shawano County Aquifer Data as a Homeowner
Recognize the median as the typical regional hardness level
The median of 204.5 mg/L suggests generally hard water across sampled wells in the area.
Consider the range to understand possible variations
Values from 48.9 to 289.0 mg/L show that some locations experience much softer or harder water than the median.
Note that all samples were below health-based limits
These numbers do not indicate health concerns but inform about potential household aesthetic impacts.
Additional Questions for Commercial or Industrial Water Users
Require higher capacity and flow considerations
Operations may need treatment equipment with grain capacity beyond typical residential levels like the 32,000-grain C-Series System.
Test for iron concentrations affecting processes or equipment
Iron levels could impact manufacturing or cooling systems beyond household concerns.
Final Step: Order a Comprehensive Iron and Hardness Water Test
Only a detailed laboratory analysis from your household supply can confirm your water’s exact iron and hardness concentrations. A result within or above the Shawano County aquifer range helps determine if the C-Series Iron + Hard Water System, which ships ready to configure and has a 32,000-grain capacity, is an appropriate solution for your home water treatment needs.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2024-08-07. 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 100SDGV aquifer (Shawano County): 10 results from 7 wells, median 204.5 mg/L, range 48.9-289.0 mg/L; none above any federal threshold
