1.1 Applicability of the ESC Process-This practice covers a process for expedited site characterization (ESC) of hazardous waste contaminated sites2 to identify vadose zone, groundwater and other relevant contaminant migration pathways and determine the distribution, concentration, and fate of contaminants for the purpose of providing an ESC client, regulatory authority, and stakeholders with the necessary information to choose a course of action.3 Generally, the process is applicable to larger-scale projects or contaminated sites where the ESC process can be reasonably expected to reduce the time and cost of site characterization compared to alternative approaches. The ESC process has been applied successfully at a variety of sites (see Table X1.1). It typically achieves significant cost and schedule savings compared to traditional site characterization (see X1.2 and X1.3),4 although it should be recognized that in-depth site characterization of hazardous waste contaminated sites may require a more elaborate process than ESC.
