Book Description
This document describes the rationale behind the development of generic soil, groundwater, and sediment quality criteria to be used in the clean-up of contaminated sites in Ontario. The document provides an overview of the environmental approach, components, and application of the revised OMEE contaminated sites clean-up criteria; describes in detail the process used in the development of the soil and groundwater clean-up criteria and the philosophical basis used in their development; and a series of summary tables that outline the specific rationales for each chemical parameter criterion.

Book Description
A critical but vexing problem with contaminated land has always been assessing the significance of contamination and the degree of cleanup required for contaminated soils and sediments. Various approaches have evolved to address this difficult issue and debate continues over which is the most appropriate. With the growing number of contaminated sites, the majority of which are non-catastrophic, interest in criteria-based approaches has grown. While there are difficulties associated with the development and implementation of generic criteria, they serve a definite purpose in an overall program for contaminated land management their usage is gaining favor in a growing number of jurisdictions around the world. 29 refs., 3 tabs.

Book Description
Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Book Description
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.

Book Description
Two documents dealing with clean-up standards for contaminated sites were issued for comment. a) A generic protocol for deriving soil quality criteria, issued by the Subcommittee on Environmental Quality Criteria for Contaminated Sites, Canadian Council of Ministers of the Environment (CCME). b) A proposed quality criterion for lead in Ontario soils, issued by the Advisory Committee on Environmental Standards, Ontario Ministry of the Environment an d Energy (MOEE). This review critiques each of the consultation documents from the perspective of the housing sector, with a special emphasis on soils in urban centres. For each document, the review summarizes the rationale in layperson's terms, identifies the relative strengths of the arguments of which it is comprised and identifies the limitations for appropriateness from the viewpoint of the housing sector. Finally, the report compares derivation methods contained in the documents. The major difference between the two documents in terms of derivation methodology, is that the CCME protocol uses an approach based on risks to human health and ecology, while the lead rationale is based solely on health concerns. In terms of the application of the criteria, it appears that the Ontario lead rationale will be more restrictive vis-à-vis housing development.

Book Description
This document reviews two publications dealing with cleanup standards (quality criteria) for contaminated sites, one a generic protocol for deriving soil quality criteria and the other a proposed quality criterion for lead in Ontario soils. The review critiques each publication from the housing sector perspective, with a special emphasis on soils in urban centers. For each document, the review summarizes the rationale for the criteria, identifies the relative strengths of the arguments involved, and identifies limitations of the criteria such as scope, errors of omission, and simplifying assumptions. The review then assesses the criteria from the soil cleanup perspective, including their flexibility to deal with different building forms and systems and the predictability of costs and work required for compliance. Finally, the review compares derivation methods contained in the two publications.

Book Description
Cleanup criteria for contaminated soil and groundwater have taken many different forms since the passage of the Resource Conservation and Recovery Act (RCRA) in 1976 and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) in 1980, also referred to as the Superfund Act. These forms have included: (1) cleanup to background levels; (2) cleanup to levels established by the limits of detection; (3) cleanup to non-detect levels; (4) cleanup to levels established by the capability of the best demonstrated available remediation technologies; (5) cleanup to levels established by precedent, for example, Records of Decisions at Superfund Sites, decisions by regulatory authorities at similar sites, et cetera; (6) cleanup to existing standards or guidelines, for example, Maximum Contaminant Levels (MCLs) established in the Safe Drinking Water Act, Action Levels in the proposed RCRA Corrective Action Rule, et cetera; (7) cleanup to levels protective of potentially exposed individuals as established by a health risk assessment; and (8) combinations of the above.
