Ward Labs
« on: March 26, 2013, 12:13:14 AM »
I received the results from Ward Labs the same week the water company sent me their published results AND they are really different.  The water company was kind enough to give me the readings from every month last year.

Ward has the sulfates really low at 37 Has anyone else thought that Ward is off on sulfates?

Calcium 41
Magnesium 17
Sodium 67
Potassium 4
Bicarbonate 116
Sulfate 37
Chloride 78
Hardness 173
Alkalinity 111
 pH 8.2

Any tips ?

You need to multiply the ward labs reading by 3 to get the right number.  This is because they report it as the ppm of sulfur, not sulfate.  Sulfur has atomic number 16, oxygen is 8, so SO4 (sulfate) is 48.

So in your case ppm of sulfate (as sulfur) is 37, ppm of sulfate (as sulfate) is 111.

This is something I learned from mabrungard here on the forum by the way :)
