Yes, these are PPM as follows:Are all these listed as ppm? My suspicion is that you are looking at their limits for detection. That is, for a particular constituent, they may not be able to accurately say that none of it is present in the sample submitted, but, they can state that it is less than the limit of detection for the particular assay they performed.
I am using your water spreadsheet so I appreciate your input on this. The converted SO4-S would have a value of 3ppm or leave it at 1ppm?For the purposes of brewing, considering any of those reported values as zero will produce no appreciable difference in your brewing outcome. But I do suggest you enter the actual non-zero results.
1 ppm SO4-S (i.e. SO4 "as" S) is 3 ppm SO4. Your report says < 1. You can't multiply "< 1" by anything. The answer could be anything that's < 3. Enter 0,1, 2, or 3. Maybe enter something like 1.5 if you want to minimize the potential maximum error. But it really won't matter.I am using your water spreadsheet so I appreciate your input on this.
