How is the Soil Matrix Tier/Level determined?

The determination of the Soil Matrix Tier/Level relies on the Soil Matrix Score, which is a calculated value based on specific criteria related to the soil's characteristics and contamination levels. This scoring system provides a standardized measure that allows professionals to classify the soil's condition in a systematic way. By evaluating factors such as the presence of contaminants, the soil type, and its capacity to attenuate pollutants, the Soil Matrix Score helps identify the risk associated with the site.

While other methods like conducting soil tests, assessing historical site usage, or visual inspections can offer valuable information about the soil, they do not provide the structured framework that the Soil Matrix Score does. This score consolidates various data points into a single numeric value that clearly indicates the soil's status, thus making it the preferred method for determining the Soil Matrix Tier/Level.
