efflorescence. is the vapor barrier compromised?

many of the inspection I perform where efflorescence is an issue I get asked where are the salts coming from. Well the answer is from moisture carrying the salts to the surface. The next question is the vapor barrier compromised? I have developed a simple test that can show this. If the vapor barrier is compromised soil will be exposed. It just so happens that soil contains Nitrates. Concrete does not. Go to a pet shop and buy a nitrate test kit. If the salts test positive than you have a vapor barrier puncture.
