What does composite sampling involve?

Composite sampling involves the process of collecting samples from multiple locations within a defined area and then combining them to form a single representative sample. This method allows for a more comprehensive assessment of the environmental conditions across the area in question, rather than relying on the data from one specific point. By aggregating samples, composite sampling can provide a better overall understanding of the presence and concentration of substances, particularly useful in CBRN reconnaissance operations where it is important to identify trends or variations in contaminant levels across a broader space. The combination of samples helps to mitigate the outcomes of sampling errors and can yield more reliable data for decision-making.
