Risk Based Contaminated Land Investigation And Assessment

Environmental Consultancy Recognition of contaminated land as a potential environment risk problem has come relatively late. However, in the 1990s there is an international agreement that dealing with such problems benefits from a risk management approach. This book provides a unique, practical guide to the effective conduct of risk assessments for contaminated sites. The risk-based approach requires recognition of site investigation as a component of (not merely an adjunct to) risk assessment and a systematic gathering of quality data relevant to making judgements about risks. This is an integrated and multidisciplinary subject. The book provides an understanding of the regulatory and social context in which contaminated land risks are managed; the interdisciplinary requirements, as well as the methodologies and their limitations for investigation and assessment. The opening chapters provide risk assessment and management background, stressing pragmatic approaches to the former. The central chapters address the means of optimising the gathering of systematic information relevant to the source-pathway-target chain of concern, including the value of multi-stage investigations. The final chapters discuss the assessment of information and data, considering qualitative, semi-quantified and quantified risk assessment approaches and the use of the findings in decision making. The book has been written to complement developing guidance and requirements in the United Kingdom, but with international comparisons. The issues which underpin effective contaminated land risk assessment are universal. The book is presented so as to be understood by readers from a variety of disciplines and with different responsibilities. It will also be of value to final year undergraduates and postgraduates in civil engineering, environmental science, environmental technology, environmental chemistry and geography. It will be of relevance to environmental and engineering consultants, companies and organisations owning or purchasing potentially contaminated land and to officers in the regulatory authorities.

This guide addresses the topics of investigation, assessment and remediation of contamination in the context of current thinking on how best to deal with the issues surrounding contaminated land, both in terms of redevelopment and from considerations of human health and environmental impacts.

Contaminated land and the methods and legal controls governing its reclamation for subsequent development and use are of great current interest and concern. This volume covers aspects of this subject, ranging from the origins and extent of contaminated land problems, including effects on human health, through investigative measures, to specific techniques of remediation. It is written in the context of the new UK contaminated land regime and includes human and ecological risk assessment methodology, and the legal liabilities and insurance aspects of contaminated land. This authoritative review will be welcomed by those involved in the areas of land use planning and development, consultants and engineers in contaminated site investigation and remediation, and environmental regulators. Students of land management and environmental science will also find it essential reading.

Land contamination is of global concern with many of the world’s industries potentially harming the environment and human health. Along with rapidly changing policy and technological developments, this is an interdisciplinary area in which successful contaminated land management depends on the expertise of and interaction between a number of scientific and engineering disciplines. Reclamation of Contaminated Land takes into account the different groups involved in contaminated land management and offers a flexible learning approach based on practical experience and research. It presents an overview of the general skills and knowledge required, encompassing both general management and regulatory practice and specific land contamination issues. Divided into two parts, Part I discusses site characterisation and the design of site investigations, and the central role of conceptual models and risk assessment in decision making. Part II discusses how risks from contaminated land are managed and the role of different remediation approaches to achieving this. This book is of great value for 2nd/3rd/4th year undergraduates and MSc students in Environmental Science, Environmental Technology, Environmental Management, Geography, Geology, Estate and Land Management. It is also key reading for undergraduates and MSc students in Chemical Engineering, Civil & Environmental Engineering and Environmental Chemistry, as well as professional planners and developers, and local authorities.

This book will outline the strategies used in the investigation, characterization, management, and restoration and remediation for various contaminated sites. It will draw on real-world examples from across the globe to illustrate remediation techniques and discuss their applicability. It will provide guidance for the successful corrective action assessment and response programs for any type of contaminated land problem, and at any location. The systematic protocols presented will aid environmental professionals in managing contaminated land and associated problems more efficiently. This new edition will add twelve new chapters, and be fully updated and expanded throughout.

Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

This standard work on contaminated site management covers the whole chain of steps involved in dealing with contaminated sites, from site investigation to remediation. An important focus throughout the book is on Risk Assessment. In addition, the book includes chapters on characterisation of natural and urban soils, bioavailability, natural attenuation, policy and stakeholder viewpoints and Brownfields. Typically, the book includes in-depth theories on soil contamination, along with offering possibilities for practical applications. More than sixty of the world’s top experts from Europe, the USA, Australia and Canada have contributed to this book. The twenty-five chapters in this book offer relevant information for experienced scientists, students, consultants and regulators, as well as for ‘new players’ in contaminated site management
