Contaminated Soil and Groundwater Chemistry, Assessment and Remediation

The detailed three-day program provides information on contaminated soil and groundwater chemistry, assessment and remediation technologies.

Course Outline

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

• Evaluate and select appropriate assessment and remediation technologies for contaminated soil and groundwater.
• Identify key data requirements and design criteria for remediation technologies.
• Understand the phased approach to site assessment and remediation with the appropriate analytical data.
• Discuss case studies that enforce the concepts, methodologies and technologies presented during the program.
• Apply the knowledge of environmental chemistry to you projects
• Benefit from the soil and groundwater sampling technologies

Description

The environmental condition of property is an important issue in real estate transactions.  Buyers and sellers must be aware of potential environmental liabilities for contaminated soil and groundwater, regulatory noncompliance, and buried wastes.  The detailed three-day program provides information on contaminated soil and groundwater chemistry, assessment and remediation technologies.  The chemistry section focuses on environmental chemistry parameters that affect contaminant distribution in the subsurface and the physical chemical parameters that determine contaminant remediation strategies. The assessment section focuses on best practices to conduct Phase I and Phase II ESAs, sampling methodologies, and data interpretation and analyses. The remediation technologies section focuses on cost effective approaches and methodologies. The remediation technologies include Soil Vapor Extraction (SVE) and Enhanced SVE, Pump and Treat Systems, free product delineation and recovery, multiphase extraction systems (MPE), natural attenuation, and bioremediation.

Objective

To provide participants with key information on contaminants, groundwater and soil chemistry, assessment and remediation

Who Should Attend

Environmental engineers, scientists, technologists, project managers, and regulatory personnel (Federal, Provincial, and Municipal).
