Wednesday I was in a meeting with EPA and state people and the term surrogate was used both ways in the same discussion, depending on whether they were chemists or microbiologists.
CLP still uses "system monitoring compounds".
As far as how little you can reliably see in a sample, good luck with that.
The closest I would get to that would be to spike every sample at the reporting limit. Certainly not practical for current technology unless your number of samples is very limited.
