What you posted was "non-carbonate" hardness - that is not the total hardness.
I measured the hardness at 12 gpg (205 ppm) via a titration test. This classifies our water as very hard.
Measurement of water hardness
According to the Water Quality Association...
soft: 0-3.5 grains per gallon (gpg),
moderate: 3.5-7.0 gpg,
hard: 7.0-10.5 gpg, and
very hard: over 10.5 gpg
