Averages for Silvan reservoir, from a number of sources a few years back as I couldn’t find it all in one place. It’s good, but has low mineral content
pH: 7.3
Calcium (Ca): 3.9 ppm
Magnesium (Mg): 1.2 ppm
Sodium (Na): 4.5 ppm
Sulfate (SO4): 0.9 ppm
Chloride (Cl): 7.3 ppm
Bicarbonate (HCO3): 13.0 ppm
Melbourne water generally do updates on the mineral content, when I say regular it may be bi annually, I was worried about mine as its coming from Cardinia which comes from Sugar loaf which comes from the de-sal plant. I would take megs8888 post and just use that as a datum.Where did you get this information i cant seem to find the mineral content in our water supply anywhere.
