After a few emails to the County, I received a detailed spreadsheet of the water report for my water source (most of the time anyway). I was attempting to use the Bru'n water sheet to help me calculate any additions I need but what my county sent me doesn't always match to what the Bru'n water sheet is looking for. For example, I have a Manganese level but nothing about Magnesium. I also have Sulfide and not Sulfate. In any case, I am hoping that someone here can shed some light on things for me. Chemistry was never my thing and despite reading various articles about water, I am still struggling to make sense of it. Below is the report for my source:

Any help is greatly appreciated.

Edit: If this belongs in the Brew Science forum, could a mod please move it there?

Thanks
 
You do indeed have Sulfate - it's just below Chloride.

What might be helpful for you is to send a sample of your actual tap water to Ward Labs and have them send back a water quality report. It's only about $15.

I've entered what I could on this calculator for you: http://www.brewersfriend.com/mash-chemistry-and-brewing-water-calculator/?id=0TXLVXL

Enter your water volumes, and then you'll want to dilute your tap water with a good bit of distilled/RO water to get your total alkalinity below say 35 ppm. For me, my tap water has a hardness of about 285, so it takes a dilution of 3:1 or even 4:1 to get it to acceptable levels. Then, you add salts to the total volume to bring up the appropriate mineral levels.

Check out this post giving a great place to start with water chemistry. Plug all of the numbers into the calculator above (you can even use a "blend" of waters - i.e. account for your dilution), and enter your salts (to mash, boil, or both). Also, enter your grain bill and it will approximate the mash pH for you as well.

It's one of the best tools for water chemistry I've seen. Super easy (much more so than Bru'nWater, IMO), and incredibly thorough.
