Contaminant distribution can be easily and accurately determined. A hole is drilled in the ground with the boring rod, and the contaminants present in the gas in the hole are measured; by taking measurements at multiple points on a site the exact distribution of contaminants can be assessed.

Alternative kits that contain the GASTEC GV-100 sampling pump instead of the plastic sampling syringe are also available: [WPT-132/WPT-133/WPT-135]
