If a contaminant of potential concern is detected at a site, how is it classified?

When a contaminant of potential concern is detected at a site, it is classified as a contaminant of concern. This terminology is important in environmental assessments and remediation because it signifies that the detected substance poses a potential risk to human health or the environment, and further investigation or action may be warranted. The classification helps prioritize contaminants that need closer scrutiny or remediation efforts.

The term "contaminant of concern" reflects a recognized status in regulatory frameworks and risk assessments, aligning with procedures and guidelines for managing environmental impacts. This classification is essential for directing resources and attention to the most pressing issues regarding pollution and ensuring compliance with health and safety regulations.

Other classifications, while they may sound relevant, do not carry the same regulatory significance or implication for action when a contaminant is detected. For instance, a contaminant of interest may be a broader term that includes various substances, but does not necessarily indicate immediate concern. Similarly, a verified contaminant could imply that there is certainty about its presence but does not specify the level of concern it represents. A source of pollution refers to the origin of contaminants but does not classify the contaminant itself.
