Ward water report help

[nudarkshadowl]

Hey guys! I just got my Ward Labs report back and I can't seem to get it to balance even after converting the Sulfate (converted figure: 219ppm) and Nitrate (converted figure: 0.9ppm) figures. My cation/anion difference is reporting .84, and I guess it could be due to round errors, but I figured I would ask anyway. Any ideas?

Here are my figures directly from Ward (not converted):

pH 7.9
Total Dissolved Solids (TDS) Est, ppm 546
Electrical Conductivity, mmho/cm 0.91
Cations / Anions, me/L 9.2 / 10.0

ppm
Sodium, Na - 88
Potassium, K - 5
Calcium, Ca - 65
Magnesium, Mg - 24
Total Hardness, CaCO3 - 263
Nitrate, NO3-N - 0.2 (SAFE)
Sulfate, SO4-S - 73
Chloride, Cl - 84
Carbonate, CO3 - < 1.0
Bicarbonate, HCO3 - 187
Total Alkalinity, CaCO3 - 154
Total Phosphorus, P - 0.02
Total Iron, Fe - < 0.01
"<" - Not Detected / Below Detection Limit

Thanks in advance for the help!

Their report is - by their own measure - unbalanced. I would ask them to redo it - and point out the cation/anion difference is greater than 0.5 meq/L

Cations / Anions, me/L 9.2 / 10.0
