What sample was analyzed?

Ask if the document refers to a specific batch, a source water sample, or another material. Without this identification, the number cannot be correctly linked to the product in question.

In which unit is the result reported?

PPM is commonly encountered, but other reporting units may also exist. A laboratory or technical report should specify the unit so that the reader does not incorrectly compare different values.

What can and cannot say the analysis?

The analysis shows the composition of a sample. It does not test on its own effects on health, taste, or performance. For these questions, other types of evidence are needed.

Conclusion

Good questions do not complicate things. They transform an isolated number into information that can be verified.
