Zero-tolerance limits
Most analyte limits on a certificate are numeric: a result at or above that number fails. A smaller set of analytes carry a zero-tolerance limit instead, printed on the certificate as “Any amt”. Any detected amount at all fails that analyte, however small. A blank or a dash in place of that limit would read as “no limit”, the opposite of the truth: it is the strictest limit a state imposes, and this site prints it as “Any amount (zero tolerance)” wherever it appears rather than leaving it blank.

distinct analytes carry this limit anywhere in the index
Where this appears
Every zero-tolerance row in the index appears on a California certificate issued by Infinite Chemical Analysis Labs. The other laboratory indexed for California expresses the identical rule as a numeric limit set equal to that analyte's own detection limit; both describe the same regulatory floor, printed differently. See the laboratory pages for which certificates use which format.

A zero-tolerance analyte is still reported using the same five-outcome vocabulary as any other. See what these mean.
