Sampling for Chemical Agents and Explosives

As noted previously, the state regulator or local oversight team must have an expert in sampling methodology. It may not be enough to take a surface or subsurface soil sample the particular toxic or explosive substance must be considered. For example, arsenic may migrate little over 70 years but other volatile substances may have disappeared altogether. 

samples taken every two feet could miss an inordinate concentration if the arsenic was deposited in a narrow band by open air testing or surface/subsurface dumping of arsenical agents. For arsenical air-deposited 

BM (Berger Mixture) 35.4% zinc, 41.6% carbon tetrachloride, 9.3% sodium chlorate, 5.4% ammonium chloride, 8.3% magnesium carbonate 

KJ Starmic chloride (a toxic World War 1 grenade filler, not recommended to fit-test masks) 

Anthracene Coal tar Polarine oil Selenium mustard Bromine compounds Experimental in World War 1
