Book Description
A range of diverse sites globally have been affected by past activities and events resulting in their contamination with residual radioactive material. As a result, there is a need to evaluate the site-specific radiological hazards and doses to people and the environment to determine whether remediation is justified and, if so, to develop and implement plans to address the situation. The IAEA has published a Generic Safety Guide (GSG-15) - Remediation Strategy and Process for Areas Affected by Past Activities or Events, which establishes a stepwise approach for the planning and implementation of remediation applying the principles of radiation protection. This publication presents the results generated from the modelling of case studies of sites contaminated with residual radioactive material from past activities and events within the Environmental Modelling for Radiation Safety (EMRAS II) programme to demonstrate the practical application of the stepwise remediation process presented in GSG-15.

Book Description
A variety of past activities and events have resulted in contamination of sites and areas by residual radioactive material. In cases where relevant criteria are exceeded, remediation should be implemented to reduce radiation exposure due to contamination, taking into account other non-radiological hazards as appropriate. Remediation includes any actions applied to the contamination itself (the source) or to the exposure pathways to people. This Safety Guide provides recommendations on the planning and implementation of remediation of sites and areas affected by past activities and events based on a systematic, stepwise approach, taking account of the specific characteristics of a given situation and the prevailing circumstances. The Safety Guide is targeted at regulatory bodies, responsible parties, operating organizations and other parties involved in the remediation of sites or areas and contributing to the recovery process to ensure the protection of people and the environment.

Book Description
For more than 100 years, the Coeur d' Alene River Basin has been known as "The Silver Valley" for being one of the most productive silver, lead, and zinc mining areas in the United States. Over time, high levels of metals (including lead, arsenic, cadmium, and zinc) were discovered in the local environment and elevated blood lead levels were found in children in communities near the metal-refining and smelter complex. In 1983, the U.S. Environmental Protection Agency (EPA) listed a 21-square mile mining area in northern Idaho as a Superfund site. EPA extended those boundaries in 1998 to include areas throughout the 1500-square mile area Coeur d'Alene River Basin project area. Under Superfund, EPA has developed a plan to clean up the contaminated area that will cost an estimated $359 million over 3 decades-and this effort is only the first step in the cleanup process. Superfund and Mining Megasites: Lessons from Coeur d'Alene River Basin evaluates the issues and concerns that have been raised regarding EPA's decisions about cleaning up the area. The scientific and technical practices used by EPA to make decisions about human health risks at the Coeur d'Alene River Basin Superfund site are generally sound; however, there are substantial concerns regarding environmental protection decisions, particularly dealing with the effectiveness of long-term plans.

Book Description
This book explores state-of-art techniques based on methodological and modeling aspects of solid and hazardous waste management, specifically focusing on the recent trends in data acquisition and robust modeling of the results obtained. In addition to an in-depth description of the recent regulatory paradigm for solid waste disposal and revealing insights into solid waste management models, the book also addresses significant case history and remediation methodologies for sustainable development in emerging economies like India, China and Brazil. The main emphasis is on a suitable regulatory framework with site-specific baseline calibration and aimed at the robust modeling of contaminant transport and its remediation. This is based on instructive case history in various locations/regions worldwide. The focus on recent modeling and quantification methods is the backbone of the book. One of the major aspects discussed is the application of non-invasive methods for studies related to the Earth's interior, which are increasingly preferred over invasive techniques thanks to their economic utility, as well as robust techniques for the interpretation of geophysical data. The increasing demand for groundwater and energy resources, especially for rapidly emerging countries with large populations like India and China, has made it vital to derive safe utilization approaches for our resources, including suitable waste disposal and remediation methodologies that can be adopted for 'contaminated sites.'

Book Description
The Department of Energy's Office of Environmental Management's (EM) mission is the safe cleanup of sites associated with the government-led development of nuclear weapons and nuclear energy. While many of these legacy sites have completed cleanup, the largest and most complex sites have not been fully remediated. The cleanup of these sites is proceeding under legally enforceable agreements with timelines for hundreds of milestones. EM is reviewing alternative approaches to increase effectiveness and improve cost efficiencies of its cleanup activities, especially for sites that will have residual contamination when active cleanup is complete. This report is the summary of two workshops convened in October 2013 and January 2014 on best practices for risk-informed remedy selection, closure, and post-closure control of radioactive and chemically contaminated sites that present significant difficulty for remediation to unrestricted release. The workshop series aimed to explore best practices that promote effective, risk-informed decision making and future opportunities to improve remediation approaches and practices.In the Workshop #1 section of Best Practices for Risk-Informed Decision Making Regarding Contaminated Sites, the report examines holistic approaches for remediating sites with multiple contaminant sources and post-closure uses, and approaches for incorporating a sustainability framework into decision making regarding site remediation, closure, and post-closure control. In Workshop #2, the report focuses on post-closure controls, assessment of long-term performance of site remedies, and best practices for risk-based remediation decisions.
