As a result of diverse industrial activities, pollution from numerous contaminant affects both groundwater and soils. Many contaminated sites have been discovered in industrialized countries and their remediation is a priority in environmental legislations. The aim of this paper is to provide the evolution of remediation from consolidated invasive technologies to environmental friendly green strategies. Many clean-up technologies have been used. Nowadays the technologies selection is no longer exclusively based on eliminating the source of pollution, but the aim of remediation includes also the recovery of soil quality. "Green remediation", a strategy based on "soft technologies", appears the key to tackle the issue of remediation of contaminated sites with the greatest attention to environmental quality, including the preservation of soil functionality.

In situ remediation techniques have experienced a boom over the last few years, thereby producing a wide range of valuable experiences. Their results have demonstrated that in situ techniques are a mature alternative to conventional remediation techniques. Irrespective of future policy developments, it is impossible to imagine future remediation practice without the use of in situ techniques. The book presents an overview of recent developments in the field of in situ soil remediation. The book is unique in that it is not a compilation of unrelated case studies. A conceptual approach has been chosen; remediation models described in this book are illustrated from a practical point of view. The authors present the Dutch way of treating contaminated land; The Netherlands is renowned for being at the forefront of remediation techniques as a result of the country's progressiveness and experience in this area

Following nuclear weapon tests, radiation accidents, functioning of mining, milling and processing industries related to fissile and fossil materials productions environments across the globe are contaminated by radionuclides representing a potential radiation exposure to humans. The book will comprise a wide spectrum of issues such as site characterization of contaminated sites before and after remediation, safety requirements, remediation planning, effectiveness of individual measures in different environments, social, ethical and economic considerations etc. It will describe modern decision aiding technologies and environmental decision support systems that can be effectively used for remediation planning and optimizing. A review of potentially effective remediation measures will be given applicable to different categories of contaminated environments and contaminants. Associated side effects (environmental and social) will also be considered. Special emphasis will be given to decommissioning of enterprises and waste management. Several case studies, demonstrating successful applications in remediation of contaminated locations of different origins: radiation accidents and incidents, areas of uranium, sand and tin mining, nuclear test sites etc., will be presented and discussed. Human based remediation measures, comprising perception of this activity by the population; to stakeholders and population involvement to making decisions on environmental safety and remediation of contaminated sites will be considered

Following the discovery of gold in the Yellowknife, Northwest Territories, Canada, area in the 1930s, Giant Mine officially opened in 1948. Gold at Giant Mine was found locked in minerals, which needed to be roasted at extremely high temperatures. Unfortunately, this roasting process also released gases with a highly toxic by-product, arsenic trioxide. Throughout the 1950s, controls were put in place that minimised emissions to the air; however, this also resulted in the collection of 237,000 tonnes of highly toxic arsenic trioxide dust. At the time, scientists and government agencies agreed that storing the waste in underground stopes and chambers was an appropriate long-term management alternative. When ore processing ceased in 1999, the care and control of the mine fell to the Department of Aboriginal Affairs and Northern Development Canada, and attention was focused on the environmental issues left behind, including the arsenic trioxide stored in underground chambers. The Giant Mine remediation project was created in 2005 with the overall goal to protect human health and safety, and the environment. To do so requires the long-term containment and management of the arsenic trioxide waste, ongoing water treatment and clean-up of the surface elements of the site. The main objectives of the Giant Mine remediation project are to minimise risks to public and worker health and safety, minimise the release of contaminants from the site to the surrounding environment, remediate the site in a manner that encourages public confidence, and implement an approach that is cost-effective and robust over the long term. The project has recently completed an environmental assessment process under the Mackenzie Valley Resource Management Act, the governing legislation in the Northwest Territories for projects with the potential to have an impact on land or water. The project team is now proceeding with a clearly defined list of requirements established through the process of the project, but faces many challenges going forward, including technical considerations, regulatory and jurisdictional constraints, consultation and engagement requirements and resource pressures. It will require a great deal of ingenuity, planning and collaboration to address these challenges and deliver a successful project for the remediation of the Giant Mine site. ; Non UBC ; Unreviewed ; Other

The chapter reflects on the impact of video and video art from the 1960s on contemporary art forms a cultural paradigm of dynamic reality. Originally, the video format was remediating the reality of TV and film production and initiating a democratization of the medium, till the 1990s and further, when video, we argue, started a revolution that emancipated digital devices after which they themselves became a part of a digital world in which we live in. From then on remediations happen not only within the media, but also on a deeper, interconnected levels of digital reality. If one cannot talk about mediations without remediations, then every mediation is always already remediating the mediated world.
