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.
A PFAS impacted site will be reviewed as a case study, and PFAS impacted soil and groundwater remediation discussed. Participants will also gain an understanding of the protocols and processes undertaken in order to investigate and remediate soil and ground water contaminated sites.
DAY 1 WHAT DO YOU DO WHEN A SITE MIGHT BE CONTAMINATED?
- How to determine if the site is known or suspected of being contaminated
- Commissioning an appropriate Stage 1 – Preliminary Site Investigation (PSI)
- What are the options following a PSI?
- Explanation of stage 1 and stage 2 site investigations
- The role of Site Auditors
- Obtaining Disposal Permits
- Guidelines and investigation thresholds:
- Overview of the NEPM Amendment (2013)
- ANZECC/ARMCANZ 2000
- NHMRC/NRMMC 2004 (Drinking Water)
- Review of the proposed changes to the Queensland EHP Contaminated Land Guidelines.
- Regulatory Considerations
- Workshop 1: Contaminated Site Assessment
DAY 2 TOOLS FOR SITE INVESTIGATIONS
- Contamination in soil: Overview of soil science; Soil sampling and analysis; Interpreting results; Techniques for remediation
- Contamination in water: Overview of ground water (hydrogeology) and surface water (hydrology); Water sampling and analysis; Interpreting results; Techniques for remediation including PFAS in groundwater.
- Determining whether to implement a SMP, RAP or remediate – Potential cost, timing, risk, effect on development, interaction with government bodies
- The reporting requirements – Contamination notifications and reporting required following remediation and validation, reviews on SMP compliance
- Workshop 2: Contaminated Site Analysis
DAY 3 SITE VISIT AND SITE REMEDIATION CASE STUDIES
- Visit to a contaminated site that has been remediated and redeveloped into a modern shopping centre. Site walkover with explanation of site history, and Site Management Plan. Site briefing notes will be provided for review on the way. Lunch break included on site. Assist in an environmental site assessment.
What do you get
- Access to leading practitioners in the areas of contaminated land and hydrogeology
- An understanding of the fundamental steps required to investigate, remediate and validate contaminated sites
- A good introduction to the relevant guidelines, investigation thresholds and regulatory requirements for contaminated land
- Course notes (hardcopy and USB) and resource material
- A visit to participate in a real site assessment
Who should attend
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.
