Response from city water department. I hope this will be helpful to someone out there.

Yes. I can help with your request.
I did a year worth of data. Below are the averages of the 7 analytes you needed.

Ca = 77.25 ppm
SO4 = 172 ppm
Mg = 10.72 ppm
Cl = 62.5 ppm
Na = 93.5 ppm
Bicarb. Alk. = 191 ppm
pH = 7.6 S. U.

Let me know if you have further questions.
Thanks

Just FYI, that looks like an average for the whole Tucson city water system, and the numbers here vary greatly from zone to zone. The total hardness may only average 55ppm in some zones, and as much as 300 in others. I'm pretty sure I have the details for zones 1 and 3 around here somewhere if anybody needs them. I also have the numbers for the Magee/La Cholla zone of the metro water system.

Thanks Juan, I am at the north end of Continental Ranch, near Avra Valley rd.
I would be interested in the details of zone 1, so post up.

The average that the city gives a good baseline, but Chimone brings up a good point in the post above... If we have a monsoon this year!

Thanks for the replies. Water is a quarter part of our beer and I have always found it to be difficult to understand.

I don't brew with Tucson water because of how wildly it varies and a lot of times it has chlorine/chloramines in it. Sup Tucson people!

Run it through a charcoal filter. Or even easier....fill up a container and let it sit overnight. The chlorine will gas off all by itself by the next day

I just buy distilled water that comes with a chemistry sheet, makes it easy!

Do you rebuild the distilled water? If so, what profile/beer are you shooting for?

I build it up per beer to best meet each beers water chemistry needs.
