System-wide figures describe finished water leaving the plant. A test at your own tap is what tells you the hardness, iron and pH your plumbing actually sees.
Hardness is a nuisance parameter, not a regulated health contaminant. See the Learn hub for treatment comparisons, or how these figures are sourced.
