Environmental · Defined
Conceptual site model (CSM)
An organized description of how contamination may originate, move through a site, and reach people or environmental receptors.
Why it matters
The model links available evidence and unresolved questions. It should evolve as sampling or site history changes the understanding of sources, pathways, and exposure.
In practice
A project example
A former solvent-use area is evaluated in relation to groundwater movement and nearby occupied buildings.
