Default Richmond, VA Water Report - Can't find the Ca or Mg in water report

Can someone identify the calcium and magnesium in this water report for Richmond, VA?. I have been trying to fill out water chemistry calculators and can't complete them without the calcium and magnesium. Maybe I am totally missing the information.

Anything else I should be aware of based on this report?

Thanks in advance!!

You are given hardness as 70 ppm as CaCO3, which is the sum of calcium and magnesium hardness. You can't know the ratio for sure, but I would SWAG 3:1 calcium hardness as CaCO3. Let's just call it 50/20.

50 ppm CaCO3 calcium hardness ~ 20 ppm calcium.
20 ppm CaCO3 magnesium hardness ~ 5 ppm magnesium.

Other than that it's pretty unremarkable and decent brewing water.

Your chloramine is on the high side (3.6 ppm), definitely refer to the new sticky about campden tablets to remove that.

Also your sulfate (49 ppm) is just high enough that I'd dilute with RO water for more delicate styles. But I'm one of those guys that doesn't like the sulfate sharpness to my hops.
