Objectives

The general aim of the course is to make students capable of handling the chain of actions pertaining to remediation of contaminated land, ranging from investigation and risk assessment to design of soil remediation and control programmes; they should also acquire a good understanding of the underlying theories and assumptions of computing models used to estimate contaminant transport and risk assessment.

On completion of the course, the student should be able to: • carry out a preliminary investigation as well as design a sampling protocol for contaminated land, • carry out both a simplified and detailed risk assessments for areas contaminated with metals and/or organic substances, • understand mechanisms of transport, turnover and effects in the environment of different organic pollutants and metals, • use some common computer-based models for transport of contaminants in soil and groundwater, • carry out an investigation and risk evaluation for different types of contaminated areas, • account for preconditions and methods for remediation of contaminated soil, • search and evaluate scientific information critically.

Content

The course is part of the ‘Soil and Environment’ semester within the programme. It consists of a 10-ECTS project and a 10-ECTS theoretical part intimately connected to the project. The project part is carried out as case assignments performed by student groups and dealing with, for instance, land set aside for building and previously exposed to contamination from a petrol station, surface treatment of metals or wood impregnation etc. Although the project is introduced in the beginning of the course, its major part is performed during the second half of the course. The project is divided into parts that that reflect the phases of realistic treatment of contaminated land.

The course content follows the different parts of the project: site investigation, risk assessment, remediation design and monitoring programs. The site-investigation part treats data collection from existing sources, sampling techniques (soil, sediment, surface water and ground water), as well as design of a sampling protocol. Central concepts in the risk assessment part are soil- and water chemistry of contaminants, transport of contaminants in soil- and groundwater as well as toxicology. Strong emphasis is placed on The Swedish Environmental Protection Agency’s risk assessment protocol, which is used and critically examined during the course. The remediation-design part treats different methods for soil remediation, including the preconditions for soil remediation. New, ‘green’ methods, such as bio- and phytoremediation, are described as well as conventional methods like soil washing. The remediation-design part also includes general costing estimates for remediation, risk evaluation and design of control programs.

The teaching is given as lectures, case studies, study visits, computer exercises and seminars. The project work is carried out in collaboration with companies and/or public authorities and is followed by oral and/or written presentation. Also guest lectures by representatives from companies and public authorities occur. Active participation in exercises as well as implementation and presentation of project work are compulsory.

Examination Formats and Requirements for Passing the Course

The following is required for a pass mark on course: • passed written examination, • passed presentations of exercises and literature assignments, • passed written and/or oral presentations of the project, • approved participation in compulsory components.
