East Austin, regular city water straight out of tap.
The report is somewhat in line with what the city reports from the two main treatment plants. Both show PH in the 9.5 range. I haven't had too many problems, as the total alkalinity or bicarbonates are not too high. Typically I end up having to add some gypsum to the mash or boil for any hoppy beer, since the sulfates are so low. I always treat my water with campden tabs as well, to remove any chloramines.
