The New Tramex

[CC Solutions]

While a drop of water being absorbed is a pretty decent field test, it is not qualitative and I sure wouldn't bet my reputation on it.... please don't take this as an all inclusive test for contaminants!

Unless an owner or GC can certify (or is willing to certify) the slab as contaminant free I will pull cores and conduct Ion Chromatography, Infrared Spectroscopy and often X-Ray Diffraction analysis on the samples.

Even then, lack of contaminants on those small 12 square inch core areas does not guarantee that the entire slab is contaminant free. It is a good start though, and with careful review of the slab and proper preparation, we can be reasonably assured of correct diagnosis and remedial action.
