Question: How is water hardness measured?

Answer: Water hardness is typically measured in grains per gallon (gpg). In the water treatment industry, hardness levels are generally classified as:

  • 0–1 gpg: Soft

  • 1–3 gpg: Slightly hard

  • 3–7 gpg: Moderately hard

  • 7–10 gpg: Hard

  • 10+ gpg: Very hard

Many homes in our region fall into the hard or very hard range.


Question: Is hard water harmful to my health?

Answer: Hard water is not considered a health concern. However, it can create problems throughout your home by causing mineral buildup on fixtures, reducing soap effectiveness, and shortening the lifespan of appliances.


Question: How does a water softener help?

Answer: A water softener reduces calcium and magnesium levels, helping:

  • Protect plumbing and appliances

  • Improve soap and detergent performance

  • Reduce scale buildup

  • Improve water feel for bathing and cleaning

Water softening can help reduce maintenance costs and improve overall water usability in the home.


Question: How can I find out my home’s exact water hardness?

Answer: General water reports provide averages, but actual hardness can vary from home to home. Tri County Water offers a free in-home water test to measure your specific hardness level and identify other common water concerns.
