This 5-hour interactive online course gives an overview of Ex Situ Remediation Technologies for Cleanup of Contaminated Soils. It also describes containment technologies (such as landfill cap) and confined disposal facilities. It is designed for scientists and environmental/civil engineers who are directly or indirectly involved in the remediation of contaminated soil, sediment and/or sludge. This course describes in detail the fundamental concepts of different ex situ remediation treatments. The treatments are separated in 5 groups as follows:
- Ex situ biological treatment.
- Ex situ physical/chemical treatment.
- Ex situ thermal treatment.
- Containment
- Excavation, Retrieval, and Off-Site
The ex situ biological treatments are: biopiles, composting, land farming, and slurry phase biological treatment. The ex situ thermal treatments include: thermal desorption, hot gas decontamination, incineration, open burn/open detonation and pyrolysis. The ex situ physical/chemical treatments are: chemical extraction, chemical reduction/oxidation, dehalogenation (APEG, BCD or glycolate), separation, soil washing, and solidification/stabilization. Finally, a brief discussion on containment, excavation, retrieval, and off-site technologies is presented.
The principles of each one of the ex situ treatment technologies are explained and information on costs, term duration, limitations, advantages and disadvantages, and types of contaminant that can be targeted are also provided.
This course can be used as a source of information to evaluate candidate cleanup technologies for contaminated sites in order to assist remedial project managers and environmental/civil engineers in selecting a remedial alternative.
There will be a multiple-choice quiz at the end of this course.
This course is designed to enable the remediation specialist to make informed decisions on ex situ remediation treatment selection in terms of cost, environment and time constraints.
After completing this course, you will:
- Be familiar with ex situ remediation technologies for cleanup of contaminated soils.
- Understand the differences between ex situ biological treatment and ex situ physical/chemical treatment.
- Understand ex situ thermal treatment.
- Be able to describe in detail the basic principles of each one of the ex situ treatment groups and have information on costs, advantages and disadvantages of using certain types of cleanup technology.
- Know how to select the appropriate technology, taking into account factors such as costs, contaminant type, soil type and the time available for remediation.
