This 4-hour interactive online course gives an overview of in situ remediation technologies for cleanup of contaminated soils. 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. The course describes in detail the fundamental concepts of different in situ remediation treatments. The treatments are separated in 3 groups as follows:
- In situ biological treatment
- In situ physical/chemical treatment
- In situ thermal treatment
The in situ biological treatments covered are: bioventing; enhanced bioremediation and phytoremediation. The in situ physical/chemical treatments are: electrokinetic separation; fracturing; soil flushing; soil vapor extraction (SVE) and solidification/stabilization. Finally, the in situ thermal treatments include: radio frequency/electromagnetic heating; electrical resistance and steam injection.
The principles of each one of the in situ treatment technologies above are explained and information on costs, term duration, limitations, advantages and disadvantages, and type 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.
After completion of this course, you will be familiar with:
- in situ remediation technologies for cleanup of contaminated soil.
- the differences among in situ biological treatment, in situ physical/chemical treatment and in situ thermal treatment.
- the basic principles of each one of the in situ treatment groups and will have information on costs, advantages and disadvantages of using certain type of cleanup technology
- how to select the appropriated clean up technology taking into account diverse factors such as: costs, contaminant type, soil type and time available for remediation.
The material presented in this course can be used as a reference guide and supporting material to screening and evaluating remedial technologies for contaminated soils, sludge and sediments.
