By the end of this training course, participants will be able to:

• Develop a conceptual site model (CSM) for any contaminated site
• Use your CSM to guide the investigation and remediation process
• Evaluate and select appropriate investigation techniques and remediation strategies for your contaminated site
• Identify key data requirements and design criteria for remediation technologies
• Apply your gained knowledge on soil, soil vapour and groundwater environmental chemistry to projects
