Reading and extrapolating from the 2009 Water report, I get the following:

Sodium, Na 33
Potassium, Not reported by city
Calcium, Ca 116
Magnesium, Mg 71
Total Hardness, CaCO3 292
Nitrate, NO3 19
Sulfate, SO4 48
Chloride, Cl 48
Carbonate, CO3 not reproted
Bicarbonate, HCO3 356
Total Alkalinity, CaCO3 not reported

Which makes me think that this water sucks for brewing day to day!

If anyone wants to chime in with a better interpretation, that would be great. I do get ground water in my area, and will be sending some water to wards for detailed analysis.

Cheers

Ca 123
SO4 36
Mg 14
Na 30
Cl 38
Alkalinity as CaCo3 181
Hardness as CaCo3 157

My current home of Waukegan, IL posts their water quality report on-line, but it doesn't include any of the mineral content information. So I called the Waukegan Water Plant this morning and they were more than happy to give me the following information:

Alkalinity: 96 mg/L
Hardness: 110 mg/L
SO4: 30 mg/L
Na: 10 mg/L
Cl: 15 mg/L

They didn't give me exact numbers for Ca, Mg, or HCO3, but said that those numbers could be derived from alkalinity and hardness. After some digging, I've estimated (although realize I could be totally wrong) those numbers to be:

Ca: 38 mg/L
Mg: 11 mg/L
HCO3: 66 mg/L

For anyone in Chicago or in Chicago suburbs that draw their water from Lake Michigan, these numbers seem to be pretty consistent (Chicago, Evanston, and Kenosha all have water reports on-line with numbers very close to Waukegan's).

Mg - 16.3
Na - 23.2
SO4 - 40.6
Cl - 12.4
HCO3 - 52.1
Ave PH = 7.7

From Ward Labs:
CA - 28
Mg - 7
Na - 37
SO4 - 27
Cl - 24

Data from North Texas Municipal Water District (serves suburbs north and east of Dallas.

For more info on sources and areas served:
http://www.ntmwd.com/watersystem.html

There is no good info online from my city (Richardson) water department, other than the normal "quality" report, but one member city (Wylie) of the NTMWD has good info in monthly reports going back several years. I assume that Richardson water would have the same mineral profile as Wylie, since they come from the same sources, and confirmed this by talking to someone at the Richardson water dept. (though I'm not sure how knowledgeable he was). I have no idea how much the treated water from different treatment plants would vary, even if they start with the same water.

The original reports are here:
http://www.ntmwd.com/water_quality.html

and I have made a spreadsheet from all reports back through 2007, just so you can see how much variation there is over time.

Spreadsheet is here:
http://www.mediafire.com/?vnq41ene3z1ek5m

One thing I don't understand is that up through August of last year, the values for HCO3 and "Total alkalinity (as CaCO3) were always different numbers and seemed to correspond to the values in Palmer's nomograph, but from Sept. 2009 to the present, these two numbers are equal. How can that be?

EDIT 9/18: Added graphs below the tables to make it clearer (don't know what happened to the x-axis labels when I converted from Open Office to .xls)

I think the total alkalinity values from Sept. 2009 to the present are actually ppm, even though they are listed "as CaCO3" in the reports. Someone forgot to multiply the HCO3 values by 50/61 ?

So now my question is: With this much variation in mineral content, should I even try to use this water, or would I be better off using RO water and building the profile from scratch?

Bump so maybe someone will see my question at the bottom of the last post.
