Which of the following is true regarding soil matrix levels for Level 2?

In the context of soil matrix levels for Level 2, the correct details align with the established thresholds for contaminants in soil to classify specific risk levels associated with heating oil tanks.

The specified levels of 80 ppm for Gx (which refers to a generic contaminant) and 500 ppm for Dx (which indicates a more specific contaminant concentration) reflect established benchmarks in risk assessment protocols. These concentrations are critical because they help determine the necessary remediation actions if the levels exceed these thresholds.

Accurate assessment of Gx and Dx levels is essential in evaluating potential environmental impacts and ensuring compliance with state guidelines. Understanding and adhering to these levels aids in the effective management of heating oil tank systems, helping to prevent further contamination of soil and groundwater.

This information is pertinent for those actively involved in the supervision and remediation processes surrounding heating oil tanks, as it directly informs their decision-making and regulatory responsibilities.
