Step 1.1 Identifying Exposure Pathway Categories
ATSDR categorizes exposure pathways as completed, potential, or eliminated.
To view a description of each category, see below.
Completed Pathway: All Five elements of the pathway are present.
Potential pathway: One element ( or more) of the pathway cannot be identified, but it is possible that the element might be present or might have been present.
Eliminated pathway: At least one element of the pathway is not present and either will never be present or is extremely unlikely to ever be present.
