The establishment of soil cleanup levels is a primary concern in site remediation projects. Soil cleanup levels provide targets that drive the remediation process from technology selection through closure. Several state regulatory agencies are currently in the process of developing scientifically based soil cleanup standards. The underlying premise in the derivation of such standards is to ensure that the site will not pose a threat to human health and the environment after remediation has been completed. To accomplish this, remediation project managers must consider several contaminant transport pathways. This article presents the salient features of a model named IMPACT, which was developed to assist in the derivation of soil cleanup levels. IMPACT considers the soil‐to‐groundwater pathway and predicts the cleanup levels in a contaminated soil layer in the vadose zone such that groundwater quality standards are met at any point in the aquifer.
