TRAINING.

Overview

After participating in the course, you will be able to:

• apply relevant regulatory tiered structure for environmental site assessment and remediation
• devise soil and groundwater sampling and analysis plans as part of site assessment
• build conceptual Site Models for site assessment and for environmental risk assessment and management
• understand the concept of modeling source-exposure-pathway concept and how to deal with uncertainties
• gain practical knowledge on conventional and innovative soil and groundwater remediation technologies and cleanup levels

Description
The current trend of land development requires a careful examination of contaminant levels in soil and groundwater along with remedial actions in form of soil and groundwater remediation or risk management. Regulations require a phased assessment of the sites under development or land use change upon which remediation and/or risk management may be found necessary. This requires both knowledge of the regulatory system, processes and procedures and the scientific and technical aspects of developing an efficient remediation or risk management strategy including but not limited to conceptual site models, soil and groundwater sampling, remediation technologies and environmental risk assessment approach.

Accordingly, remedial actions can be designed to meet regulatory cleanup levels.

This course will provide the participants with the essential knowledge on the phased structure of Environmental Site Assessment, followed by characterization of contamination and associated environmental risks aimed at achieving appropriate remediation design.

Course Outline

• Regulatory framework and phased approach for environmental site assessment
