When should BTEX/PAH be run during Risk-Based Cleanup?

In the context of Risk-Based Cleanup, it is essential to identify the most contaminated areas to determine the extent of potential harm and to establish appropriate remediation strategies. Running BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) and PAH (Polycyclic Aromatic Hydrocarbons) analyses on the highest sample result is critical because these compounds are often associated with serious environmental and health risks. By focusing on the highest concentration, cleanup efforts can be guided to address the areas with the most significant contamination first, thus prioritizing risk management.

This approach helps ensure that any immediate threats to human health and the environment are dealt with as a priority. It allows for more effective resource allocation during the cleanup process. Moreover, identifying the maximum levels of contaminants can lead to a better understanding of the potential for exposure and the effectiveness of cleanup measures, informing future sampling and remediation efforts.
