My town utility board has posted it's water quality report online, and it appears to contain a lot of useful information but I'm having a tough time deciphering what it means for brew water. These two pages contain most of the hard numbers:
I've been trying to use John Palmer's nomograph
to figure out my beer my water is best suited for.
The report states my Alkalinity is 55ppm, but should I consider that the Alkalinity (2nd scale) or the Residual Alkalinity (top scale)?
It also states the water Hardness is 125ppm. Should I use that as my effective hardness? If I plug that into the graph and use the 55ppm on the second scale, I end up with a fairly low starting PH around 5.6. If I just use it as the Residual Alkalinity, it a much more average 5.8!
If anyone could help me learn more about my reading this report I'd certainly appreciate it.
