Sampling of groundwater, soil, soil vapor, or indoor air can be part of forensic source sampling. Passive soil vapor surveys using U.S. EPA Method TO-17 provide a laboratory analysis of volatile organic compounds (VOCs). The sample modules can be placed on a grid for a rapid property-wide assessment.
Forensic subsurface contaminant maps (one for each target chemical) provide an up-to-date view of conditions. The source of contamination can frequently be interpreted from the maps. Outdoor air can be affected by a variety of factors and the process of identifying the source of contaminants, particulates or odors is complex.
