- Environmental Engineering Training
- 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 do the following:
• evaluate and select appropriate assessment and remediation technologies for contaminated soil
• identify key data requirements and design criteria for remediation technologies
• understand the phased approach to site assessment and remediation
• apply the environmental chemistry methodologies and technologies to your projects
• use soil and groundwater sampling technologies
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 non-compliance, and buried wastes. This seminar provides information on contaminated site assessment and remediation, focusing on cost-effective approaches, methodologies, and technologies. Case studies, which are included and distributed as part of the seminar, are based on real projects that will reinforce your understanding of the concepts and methodologies.
The chemistry component of this course focuses on parameters that affect contaminant distribution in the subsurface and determine contaminant remediation strategies. Best practices for conducting Phase I and Phase II ESAs, sampling methodologies, and data interpretation and analyses will all be covered as well. The course will also examine cost-effective remediation technologies such as soil vapour extraction (SVE) and enhanced SVE, pump and treat systems, free product delineation and recovery, multiphase extraction systems (MPE), natural attenuation, and bioremediation.
To provide participants with an understanding of groundwater and soil chemistry, possible contaminants, and appropriate assessment and remediation strategies.
Who Should Attend
Environmental engineers; scientists; technologists; project managers; and, federal, provincial, and municipal regulatory personnel.
