Contaminated Site Assessment and Remediation

IWES, University of Queensland, WaterAid Contaminated Soil and Groundwater

Target Audience

The course is specifically designed for anyone who is dealing with issues related to contaminated land or ground water. The course will provide insight and understanding to assist people to work with environmental consultants or local councils, and will be invaluable for environmental scientists, engineers, consultants, town planners or developers wishing to enhance their knowledge of contamination issues and processes.


The aim of this course is to provide an overview of the required processes for managing contaminated or potentially contaminated sites. The course explains what steps need to be taken when you encounter soil or water contamination, what options are available, and the regulatory requirements that need to be satisfied.

Participants will also gain an understanding of the protocols and processes undertaken in order to investigate and remediate soil and ground water contaminated sites.
