I've run a dozen or so ICP over the years and never recall seeing Copper in any of them. This is my first ATI test, and my RO/DI came back with copper at 3.61. The reference level for this is 0.0, but the report did not "Flag" it as out of range. My tank water came back with 1.95.
I gather from other RHF posts that anything under 10 is nothing to worry about. Can I get a confirmation on that?
I run a 7 stage with 2 carbon and cation, anion, and mixed as my final. I show 0 TDS, but where could it be getting through? What should I be more aggressive about replacing even before I touch >0 TDS? Or do I just need to chill out and have a few beers?
