Ice, technically. But what you’re really referring to is household water that contains dissolved minerals (usually calcium and magnesium) above 1 GPG (grams per gallon).
Water is classified as follows:
- Soft Water – less than 1 GPG
- Slightly Hard – 1 to 3.5 GPG
- Moderately Hard – 3.5 to 7 GPG
- Hard – 7 to 10.5 GPG
- Very Hard – 10.5 and higher GPG
To determine your water’s hardness, you can call your local water department if you have municipal service. For wells, contact a local water lab to arrange for an analysis. Hard water is typically addressed by installing a water softener.
Remember, these tips are only general guidelines. Since each situation is different, contact a professional if you have questions about a specific issue.
