Ok, email's went through today, heres the report from the chemist, he mentions nothing about brewing, im not sure what happened there...
The water at your location is from 5 different sources in a constantly varying ratio. Typically, we analyze the water at the source and not in the distribution system, so this is my best estimate of your water quality at the monastery.
Sodium: 10-20 ppm
Total Hardness (CaCO3): 60-100 ppm
Nitrate: 0-0.5 ppm
Sulfate (SO4-S): 0 ppm
Chloride: 20-40 ppm
We do not have information on the other components, and unfortunately we cannot offer analytical services for sale. If you are interested in further analysis of your water, I would recommend that you contact one of the Oahu environmental labs, such as AECOS. The other tests would be fairly inexpensive. If you have any more questions, please feel free to contact me by email or at the number below.
