Course objectives

Training students for independent and team work in identifying the specific locations of contamination in the environment, and the selection and application of methods of remediation.

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

It is expected that the outcome of learning to provide knowledge about:
- methods of identifying contaminated sites in the environment
- determining the type of contaminants and contamination intensity
- the selection procedures for remediation of environmental
- application of methods of remediation.

Course content broken down in detail by weekly class schedule (syllabus)

1st week: Assessing the state of the environment. Methods for identification and testing of contaminated sites in the environment.
2nd week: Types of pollutants. Qualitative and quantitative identification of contaminant in the contaminated site.
3rd week: Factors influencing migration (spreading) of contaminants in the environment. The role of soil and sediment in retaining and slowing ground water contamination.
4th week: Models of migration of contaminants in the environment.
5th week: Environmental remediation techniques: in situ, on site, ex situ. Selection criteria for remediation technologies.
6th week: Technologies for remediation of soil. Physical remediation: soil encapsulation. Excavation of the soil. Mixing of soil.
7th week: Chemical soil remediation: electrochemical remediation, flooding, flushing, solidification / stabilization, natural cleaning.
8th week: Thermal soil remediation: incineration, vitrification, solar / photochemical degradation of the soil.
9th week: Biological soil remediation: bioremediation, bioventilation, phytoremediation, phytoextraction / phytoaccumulation.
10th week: Remediation of sediment
11th week: Remediation of groundwater. Ex situ physical / chemical processes: stripping, adsorption, oxidation, separation.
12th week: Remediation of groundwater. In situ physical / chemical processes: ventilation, stripping, permeable reactive barriers, oxidation.
13th week: Bioremediation of groundwater. Passive bioremediation. Biostimulation / Bioaugmentation.
14th week: Phytoremediation. Rhizosphere biodegradation. Fitodegradation.
15th week: Phytostabilization. Rhizofiltration. Phytovolatilization.
Seminar: Analysis of examples of remediation of contaminated sites in our country and in the world.
Exercises: Identification of contaminated environment and selection of the appropriate remediation techniques. Remediation of contaminated groundwater by using permeable reactive barriers. Calculation of distribution coefficient. Prediction of migration distribution of harmful substances in the environment. The use of flotation in the remediation of contaminated sediment. The application of dewatering in the remediation of the environment. Efficiency of dewatering of contaminated sediment and purity of the filtrate. Electroremediation of sediment polluted with heavy metals. Phytoremediation.

Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
