Objectives
Training outcomes
- Plan the stages of a contaminated site assessment and build the conceptual site model.
- Assess risk on the basis of source, pathway and receptor, and set remediation objectives.
- Understand the principles of in situ and ex situ remediation technologies and the limits of each.
- Compare options and select the technology suited to the contaminant and site conditions.
- Prepare the monitoring plan, verify that remediation objectives are met, and close the site.
Content
What the programme covers
Day 1: contaminants and site assessment
- Common industrial contaminants: petroleum hydrocarbons and BTEX, chlorinated solvents, heavy metals, and light and dense non-aqueous phase liquids (LNAPL and DNAPL).
- Stages of site assessment: records review and the initial visit, then intrusive investigation with soil, groundwater and soil gas sampling.
- The conceptual site model, the implementing regulations of the Environmental Law on soil and contaminated sites, and the role of the National Center for Environmental Compliance.
Day 2: risk assessment and remediation objectives
- Human health and environmental risk assessment: source, pathway and receptor, and exposure pathways.
- Setting risk-based or guideline-based remediation objectives, and the technical feasibility of options.
Day 3: soil remediation
- Ex situ remediation: excavation and transport to a licensed facility, soil washing, thermal desorption, and bioremediation in biopiles and by landfarming.
- In situ remediation: soil vapour extraction (SVE), bioventing, stabilisation and solidification of metals, and phytoremediation.
Day 4: groundwater remediation
- Pump and treat, air sparging, and free-phase product recovery.
- In situ chemical oxidation with persulfate, permanganate and Fenton’s reagent, reduction with zero-valent iron, permeable reactive barriers, and enhanced bioremediation.
- Monitored natural attenuation and the conditions for relying on it.
Day 5: plan, monitoring and closure
- The remediation plan: outline design, pilot tests, site safety and management of the wastes generated.
- The monitoring programme, verifying that objectives are met, and the closure report.
- A case study of a contaminated industrial site in which participants select a technology and justify their choice, followed by the assessment.
Who it is for
Target audience
Engineers and environmental specialists in industrial facilities and environmental consultancies, and staff of regulatory bodies responsible for contaminated sites.
Method
Delivery method
Lectures and case studies of industrial sites, and a group exercise in selecting a remediation technology and preparing its plan. The case study can be built on data from one of the organisation’s sites if it is shared with the centre before the programme. In Arabic or English.
Questions
FAQ
Does the programme cover how contaminants behave and move underground?
It covers what is needed to select a technology and focuses on assessment and remediation. Contaminant behaviour and transport modelling in detail are the subject of Nature and Behaviour of Contaminants in Subsurface Environments.
Can we work on one of our own sites?
Yes. If the organisation shares the site data and available investigation results before the programme, the Day 5 case study is built on them.
A programme tailored to your organisation
The duration and topics of the programme are adjusted to the organisation's needs, and it is delivered at its site, in a training hall arranged by the Center, or virtually.
