Short description: Applicability of the ECS Process-This practice covers a process for expedited site characterization (ESC) of hazardous waste contaminated sites to identify vadose zone, ground water 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. Generally, the process is applicable to larger-scale projects, such as CERCLA (Superfund) remedial investigations and RCRA facility investigations. The ESC process is also applicable to other contaminated sites where the ESC process can be reasonably expected to reduce the time and cost of site characterization compared to alternative approaches.
