A conceptual site model includes which of the following elements?

A conceptual site model (CSM) is a critical tool in understanding and communicating the conditions and potential risks at a site with contamination issues. It incorporates various elements that help depict the relationships between contamination sources, the pathways through which contaminants may move, and the potential receptors that could be affected.

The correct response emphasizes the importance of identifying those affected and the sources of contamination. This identification is essential for assessing risks associated with the contamination and planning appropriate remediation actions. Understanding both the sources of contamination and the individuals or ecosystems that could be impacted allows for a comprehensive risk assessment and management strategy.

In contrast, while descriptions of economic impacts, market values, and even known sources of contamination can be relevant in context, they do not encompass the primary goal of a conceptual site model, which focuses on how contamination flows and who or what may be exposed, rather than solely presenting economic variables or isolated aspects of contamination.
