What must be present to determine a site qualifies for a Level 3 cleanup according to soil matrix parameters?

To qualify a site for a Level 3 cleanup according to soil matrix parameters, it is essential to identify the correct numerical value that indicates the level of contamination or the threshold for remediation actions. A numerical value below 25 signifies that the contaminant concentration in the soil is relatively low, which aligns with the criteria for a Level 3 cleanup, suggesting that the site may pose a lower risk and require less intensive remediation measures.

This level typically indicates that further investigations and layers of assessment may be warranted, yet the contamination does not exceed thresholds that necessitate immediate or more aggressive cleanup interventions. Therefore, identifying a numerical value below 25 confirms that the site meets the parameters for a Level 3 classification, supporting targeted and appropriate responses based on the contamination level present.
