Abstract

This paper serves as the written guideline for contaminated site remediation projects, and Provides a framework for the key issues such as contaminated sites management process and decision framework for technology selection that need to be considered throughout remediation programs, to ensure that reports prepared by consultants, Contractors, or and any responsible party on the investigation and remediation of contaminated sites project contain sufficient and appropriate information. And to enable efficient review by regulators, the Site Auditor and other interested parties. In this paper, we eliminate the fact that the soil characteristics is a very important element in the remediation technologies selection process as site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. This concludes the fact that we have to evaluate the technologies on the base of the contaminants and soil characterization. The effectiveness of the remediation technologies depends on three groups (Contaminant and site Characteristics, Regulatory Requirements, and Cost limitations); the Effectiveness of Technologies Dependency (ETD). Contaminate prospective, and RI/FS a very important element in our decision framework on the Contaminated Site Management and Technology Selection Process (CSM&TSP). Up on site characterization and the site investigation data requirement, technology group could be identified either In Situ or ex situ. The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics, and because the efficacy of the process is more difficult to verify. The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. Ex situ treatment, however, requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and material handling/worker exposure conditions. In this paper Contaminated Site Management and Technology Selection Process (CSMTSP) has been introduced as a guideline for Remediation Project Managers RPM to support their technology selection decision. Information in this paper is intended to give project managers a comprehensive understanding of the process to screen and select treatment technologies for specific contaminated sites, and guidance for further consideration of treatment technology and its applicability.
