Well, I got my results back and it seems that they used a synchrometer and gave +/- results. I guess I shouldn't be too surprised, since they only charge $15 a pop. It would have been hundreds for analysis using more conventional lab methods. I have half a mind to go to my lab and run a pad myself but I don't think I can justify the expense.
Doctor V, have you (or your affiliated lab) correlated the synchrometer results to an ICP for the metals and maybe a GC of some variety for the organics? Just curious - I can't turn off my chemist's brain all of the way when it comes to this stuff! Maybe the intention is to get just a slate full of negatives and the change over time is proof enough??
BTW, here are the actual results, in case anyone is curious:
