I had our analyst run my well water through the lab and there were no (detectable) levels of sodium, potassium, calcium, or iron. He did detect a tiny amount of zinc.

Ask them if they can check hardness. Go here for a brief explanation.

I’ll ask the analyst but, based on the fact that he didn’t detect calcium, according to the USGS link the water would have to be considered ‘soft’.
