Sorry to post a follow-up so quickly but thought of this just as I hit
the 'Post' button.

You oughta be.

Did a quick search and came-up with the following "Hardness" table.
(Saw several but just closed my eyes and grabbed one.)

0 to 70 PPM (Very soft water)
70 to 140 PPM (Soft Water)
140 to 210 PPM (Medium Hard)
210 to 320 PPM (Fairly Hard)
320 to 540 PPM (Hard)
540 PPM and above (Very hard)

Why don't you tell us what industry and association publishes and uses that
chart. It certainly isn't commercial or industria type folks or the water
treatment industry. Actually it isn't anyne that needs quality water for
whatever thier intended use.

According to this, my water ranges between 'Soft Water' and 'Medium
Hard' i.e. 120-175 ppm Total Hardness as CaCO3.

Interesting that your industry, Gary, only has one definition for
'Soft Water' while everyone else uses ranges... but then everyone else
isn't trying to sell softeners. [$cha-ching$] ;-)

Name us other industries that use your chart and would agree with your
personal preferrence for hard water when they need to improve their water
quality.
