What is essential for the evaluation of how contaminants are likely to move?

The evaluation of how contaminants are likely to move is fundamentally supported by a conceptual site model (CSM). A CSM provides a comprehensive framework to understand the relationship between contamination sources, pathways, and receptors by integrating various data layers, including geologic, hydrologic, and chemical information. It visually represents how contaminants can migrate and spread within the environment given specific site conditions.

In practice, a well-constructed CSM enables environmental professionals to predict the behavior of contaminants, identify potential risks to human health and the environment, and develop effective remediation strategies. Without a CSM, understanding the dynamics of contaminant transport would be significantly hindered, making it challenging to assess the site’s potential impact accurately.
