Which factor is NOT considered in determining the Soil Matrix Score?

The factor that is not considered in determining the Soil Matrix Score is soil temperature. The Soil Matrix Score primarily evaluates the characteristics of the soil and its ability to contain or transmit contaminants.

In assessing the Soil Matrix Score, depth to groundwater is critical because it determines how quickly contaminants can reach the water source. The sensitivity of the uppermost aquifer is also essential, as it indicates the potential risk to this water supply from contaminants present in the soil. Additionally, potential receptors are important to identify, as they represent the entities (human, wildlife, or ecological) that could be adversely affected by contamination.

Soil temperature, while it can influence biological and chemical reactions within the soil, does not specifically provide relevant data for assessing the potential impact of contaminants within the context of the Soil Matrix Score. Understanding which factors are relevant aids in evaluating environmental risks associated with heating oil spills and other related incidents.
