Default Partial Mash - Ph of City Water OK

Here is the WQ report from my water supplier (Butler County OH - BCDES) ---From the Website, not a sample at my house----

Total Chlorine---- 0.74 mg/l
pH---------------9.1 S.U.
Fluoride----------0.98 mg/l
Total Alkalinity--- 64.3 mg/l n
Total Hardness---135 mg/l (7.8 gpg)
Sodium---------- 30.5 mg/l

I plan to do a Partial Mash (AHS Karankawa Pale Ale).I understand the mash needs to be in the 5.0-5.5 range, is my Ph range OK?

Any other 'fatal flaws' in that limited data?

An aside, can you get Ph strips and any 'ole pharmacy'?

TIA
Dan

It's hard to say since you don't list Ca or Mg concentrations, but your alkalinity looks good.

Yes, I would say the "fatal flaw" is that it's chlorinated water. Chlorine can combine with malt phenol to form chlorophenol. A surprisingly small amount of this substance can give your beer a "medicinal" undesirable taste. I have never brewed with my tap water and this is why I never will. It's too bad because I hate having to buy those 2.5 gallon jugs of Ice Mountain natural spring water, but I do, and have never had a problem with this water. Take care....and my advice is stay away from chlorine.

I can boil the water before I use it, this will evaporate the Cl?
I would also precipitate the Alkalinity?

Boiling removes chlorine, but not the ever more popular chloramine. Just crush up a campden tablet and add it to your mash, sparge and boil water. 1 tablet treats 20 gallons, and the reaction is almost instant. I do this and have never had an issue with chlorophenols.
