ABSTRACT

Selection of the most appropriate remediation technology must coincide with the environmental characteristics of the site and the ongoing fate and transport processes. To be sustainable, the risk at the site must be reduced, and the risk should not be transferred to another site. The treatment must reduce the risk to human health and the environment. Cost-effectiveness and permanent solutions are signicant factors in determining the treatment, as is done for Superfund remedies (USEPA, 2005). Development of multiple lines of evidence (LOE) to reach decisions is becoming more frequent and should be utilized by regulatory agencies.
