For site cleanups with conditions linked to TPH-Dx concentrations, what is crucial to determine?

Determining pollutant mobility is crucial in site cleanups linked to TPH-Dx (Total Petroleum Hydrocarbons-Diesel range) concentrations because it affects the spread and concentration of contaminants within the soil and groundwater. Understanding how pollutants move through the environment helps in assessing the potential impact on human health and the surrounding ecosystem. Factors that influence pollutant mobility include the physical and chemical properties of the contaminants, the soil’s characteristics, and environmental conditions.

By knowing how easily TPH-Dx can migrate or degrade in the environment, remediation strategies can be tailored effectively, ensuring that cleanup efforts are both efficient and protective of public health and the environment. It guides decisions on the methods of remediation required and helps prioritize areas within the site that need urgent attention based on pollutant behavior.
