Exposure pathway
The route by which a contaminant can move from a source to a person or other receptor.
Why it matters
Presence of a substance and an actual exposure pathway are different questions. Site use, building conditions, and environmental transport determine what needs further evaluation.
In practice
A project example
Contaminated soil below a paved area presents different exposure considerations if the site is later excavated.
