Calculating HCO3 from "Hardness' in Water report
« on: February 21, 2021, 01:07:03 PM »
Hello guys,

I am looking for some assistance on how to calculate my bicarbonate. I have attached my water report and the only thing I see that may have to do with bicarbonate is "Hardness" which is listed in a range of 32.7- 34.2. Is there a way to know what my bicarbonate level is from this since it is not listed directly?

 Thanks,

Dan

Does it list alkalinity? Alkalinity of water in the US is determined by the soil and bedrock through which it passes. The main sources for natural alkalinity are rocks which contain carbonate, bicarbonate, and hydroxide compounds. Borates, silicates, and phosphates also may contribute to alkalinity.

Bicarbonate computed = alkalinity * 61/50.

I did find another report that has alkalinity at 28 mg/L.

So would it be safe to say I can plug in 34.16 to my bicarbonate for my water profile? 28* (61/50)?

I believe that is correct. If so, it?s a pretty low bicarbonate so that good.
