Written exam. In case of unclear answers, an oral test is followed to clarify them.

1) Introduction to the problematics of old ecological burdens. Definition of remediation and decontamination, general principles of decontamination procedures.
2) Legal aspects of old ecological burdens, risk analysis and survey of contaminated territory, risk assessment in connection with decontamination work.
3) Terminology connected with problematic of decontamination. Main groups of contaminants and their properties from the perspective of decontamination technologies.
4) Basic classification of decontamination methods.
5) Methods for decontamination of the rock environment - overview. Contaminated soil - definition and basic characteristics.
6) Natural methods of decontamination with a focus on biological methods in situ - basic classification and principles of biological methods. Bioventing and phytosanation.
7) Physical and mechanical methods of decontamination and remediation in situ; vitrification, stabilization, solidification, encapsulation – description, principles.
8) Chemical methods of decontamination in situ; classification and basic characteristics. Oxidation reduction methods.
9) Overview of decontamination methods used for contaminated soil ex situ; biological, chemical, physical methods – principles, description.
10) Decontamination methods of main pollutants of the rock environment - of PCBs, PAHs, oil products etc.

12) Groundwater decontamination – methods used in situ. Treatment walls.
13) New directions in decontamination technologies; nanoparticles, membranes etc.

The aim of the subject is to acquaint students with the legislative framework of soil protection. Provide comprehensive information concerning the problematics of contaminated areas. Explain the process of risk analysis of contaminated territory and reasons of survey that precedes the decontamination process. Provide basic information of principles of conventional and modern decontamination methods focused on rock environment with the emphasis on polluted soils.
