The course provides a comprehensive overview of technologies used in the remediation of contaminated sites with a focus on the removal of old ecological burdens and contamination of soils, rock environments, groundwater and seepage waters and soil air. Students will become familiar with biological, physical, chemical and thermal remediation technologies carried out in situ and ex situ, their principles, areas of application, technical limitations and economic aspects. Attention will also be paid to modern and innovative approaches, including phytoremediation, reactive barriers, natural and assisted attenuation, thermal methods and the use of nanotechnologies. Emphasis will be placed on the choice of an appropriate remediation technology with regard to the nature of the contamination, the properties of the rock environment, hydrogeological conditions, the required level of remediation, environmental impacts and economic efficiency.
Professional knowledge: The student characterizes the main types of contamination of the rock environment, soils, groundwater and soil air and explains the principles of biological, physical, chemical and thermal remediation technologies. He distinguishes between in situ and ex situ technologies and describes their possibilities, limitations and conditions of use. He is familiar with the technologies of remediation of unsaturated and saturated zones, purification of groundwater and seepage waters and soil air and knows the principles of modern and innovative remediation procedures. He explains the basic technical, environmental and economic criteria influencing the selection of remediation technology.
Professional skills: The student analyzes the basic characteristics of a contaminated site and, based on the type and extent of contamination, the properties of the contaminant and the conditions of the rock environment, proposes a suitable method of remediation. He is able to compare alternative remediation technologies, assess their technical feasibility, efficiency, environmental impacts and economic complexity and justify the selection of a suitable solution. He applies the acquired knowledge when solving specific cases of remediation of old ecological burdens, industrial and post-mining sites.
General competencies: The student is able to independently obtain and critically evaluate professional information on remediation technologies, work with different solution options and formulate and defend a professionally based proposal for a remediation procedure. He/she is able to connect environmental, hydrogeological, technological and economic aspects when dealing with contaminated sites and to cooperate with experts from various professions in the design of a comprehensive remediation solution.
