What this means at home
Hard water can leave scale on fixtures and appliances and can reduce soap lather. It is not listed as a health contaminant on EPA’s secondary standards list. A softener or whole-house filter is a purchase decision based on your fixtures, taste preferences, and a test of your own tap, not on a city average alone.
