I was plugging my water report from the city into EZ Water Calculator and I had a few questions?

Bottom of the report says 1 ppm = 1mg/L = 1000 ug/L

My Calcium is 23 mg/L
My Magnesium is .94 mg/L
My Soduim is 1.9 mg/L
My Chloride is 3.6 250mg/L (how do I calcuate that into ppm? 250x3.6?
My sulfate is 1.4 250mg/L (how do I calculate that into ppm? 250x1.4?

The 250mg/L figures are probably allowable upper bounds.

Does the report have alkalinity or carbonate numbers?

Alkalinity mg/L is 20.2
I dont see carbonate... Organic carbon is .85 mg/L

So for Chloride and sulfate I use 3.6 and 1.4.

That seems awfully low considering EZ calc shows way higher "normal" limits

Bicarbonate is calculated from alkalinity as is carbonate. Alkalinity is not expressed as just mg/L but rather in mg/L as Calcium Carbonate and more usually ppm as Calcium Carbonate. Look to see if either of those phrases is there.

Yes - 3.6 mg/L for the chloride and 1.4 mg/L for the sulfate. The water in your part of the country comes mostly from rain and snow melt and is, this very low in minerals. You are lucky.

If you have alkalinity and ph (it would be surprising if the water report didn't have those), Bru'n water will estimate bicarbonate and carbonate. I've had to use this function with my water report and have had good results.
