Crap, I used the wrong numbers too. I got them switched around.

For MAWC districts South and Meramec:

Total Hardness avg 99.8
NON C Hardness avg 31.4 (Ca 18.3 + Mg 13.1)
-------------------------------------------------------
C Hardness Avg 68.4 ppm

Milliequivelents of hardness avg is 99.88 using Palmers formula.

JJJ, how does that translate in Promash? What are the units? I've downloaded ProMash and haven't figured out the water numbers yet.

With 68.4 ppm carbonate, Palmers formula gives CaCO3 hardness as 171 (confirmed with promash). Then using Promash, CaCO3 hardness at PH of 10.03 translates to HCO3 of 104.19

These tools are available in the water entry window. On the bottom of the Promash screen click water, you can then add a water profile. In this screen you can access the calculator I used for this.

Just moved to STL and trying to get a feel for the water profile. After reading this thread I am thoroughly confused. Can someone post the final water profile for south STL?

City or County? They are quite a bit different depending. There are actually 2 different water treatment entities.

If you get you're bill from Missouri American Water the posting I made regarding my water supply should work for you. It's for the South and Meramec regions of distribution.

It's fairly alkaline....
