For a Level 3 Soil Matrix, what is the maximum permissible concentration?

The maximum permissible concentration for a Level 3 Soil Matrix is significant because it helps ensure that contaminated soil does not pose a risk to human health or the environment. A Level 3 Soil Matrix typically reflects a higher level of contamination and a more complex environmental setting where additional assessment and remediation actions may be required.

In this context, 1000 ppm is the correct concentration level because it serves as an industry standard threshold. Levels above this can indicate severe contamination and may necessitate further investigation or remedial measures to mitigate potential risks. Monitoring this level helps protect public health and the surrounding ecosystem.

The other concentration options – 500 ppm, 1500 ppm, and 2000 ppm – do not align with established guidelines for Level 3, as they either indicate a lower threshold that may not reflect the severity of the contamination or suggest a higher threshold that could overlook necessary safety precautions. Thus, 1000 ppm acts as a critical benchmark for evaluating potential soil contamination in scenarios classified as Level 3.
