Central Coast Water Report

[Gingerpete]

Hey everyone,
Just in case you're interested I have posted the Wyong/Central coast water report listing average ion concentrations relevant to brewing. Its all there (except SO4)- Ca, Mg, Cl, Na, Total Hardness in HCO3 and H2CO3. Should be all you need for calculating your water additions.
One thing to note - Low Calcium!
As it didn't come with sulphate levels, does anyone have access to this level?

Damn, I cant attach it. Ill just try and paste below

Water Suppy Authority − Wyong Shire Council (WY)
Supply System − Wyong (01)
Date Range −
From − 11 April 2011
To − 11 April 2012
Sample Type/s − All
Laboratory/s − All
Parameter/s −
Calcium - 16.35 mg/L
Chloride - 58 mg/L
Mg - 4.8 mg/L
pH - 7.44
Na - 180 mg/L
Total Hardness as CaCO3 - 60
Treated Carbonate Alkalinity - 0 mg/l expressed as calcium carbonate
Treated Bicarbonate Alkalinity - 30 mg/l expressed as calcium carbonate

I use gosfords one from 2009-2010
Ca 14
Chloride 72
S04 39
Total hardness as CaC03 58

They are similar numbers when I compare the printed one I have to the numbers you've posted...one glaring difference is that sodium in 2009 was 55 compared to 180

We like it salty up here.
Do you do any mineral additions or pH testing Sama?

Yeh i all ways add calcium,usually calcium sulphate and calcium chloride.When I get a new recipe I work out how much calcium to add to get me in an acceptable mash ph and calcium levels above 50ppm.add calciumm mix to mash and test with a digital probe I got from jay car.I don't bother with additions to sparge water so probably not getting calcium up very high in final product but I do add yeast nutrient prior to end of boil.for example,kolsch I make gets 3gms each of cs04 and calchloride.
P.s also us either more or less of each calcium to get me a calcium/sulphate ratio that's apparently optimal for style...you know what imeen,,I think

Thanks for that Pete,
I think that may come in handy!

just from a sensory point of view, i have noticed that my water smells of chlorine.
would be interesting to know if the numbers have gone up from a few years ago

Thanks for posting this. I've been searching for this info for a while and even called council with no luck.

So based on the results, what is the best way to calculate what & how much additions to use?

So what additions would you want in tank water ?
I guess we would have a bit of dust from the roof.
