International Technologies for Hazardous Waste Site Cleanup


Book Description

"From the Introduction: " The purpose of this program is to identify and assess international technologies that could be utilized for hazardous waste site remediation within the United States. This report summarizes the results of Phase I of this program, which identified international alternative technologies potentially applicable to Superfund site remediation. All remedial technologies identified as a result of the Phase I activities are described in this report. Recommendations are also provided for further study in Phase II which will focus on the most promising international technologies. General Approach The technical approach for Phase I focused on the location, acquisition, and interpretation of existing data, studies, and related documentation for remedial technologies. Data were obtained through a comprehensive literature survey and telephone contracts / interviews with agencies, industries, vendors, research groups, and others involved in the development and marketing of technologies. Emphasis was placed on technologies that have been developed and / or applied in Europe, Japan and Canada, because of the promise that these areas have more advanced hazardous waste programs in place. An important part of the Phase I activity was the assembly and review of information that EPA scientific personnel have obtained in their foreign travel assignments or through contact with foreign consultants or academics. A list of EPA personnel that were contact for input to the Phase I technology identification activity is provided in Section 4, along with non-EPA contacts . . . .




Unit Operations in Environmental Engineering


Book Description

This book discusses the practical aspects of environmental technology organized into eight chapters relating to unit operations as follows: 1. Biological Technology 2. Chemical Technology 3. Containment and Barrier Technology 4. Immobilization Technology 5. Membrane Technology 6. Physical Technology 7. Radiation and Electrical Technology 8. Thermal Destruction Technology Traditional technologies have been included, as well as those that can be considered innovative and emerging. The traditional approaches have been the most successful, as contractors are careful about bidding on some of the newer technologies. However, as regulatory requirements increase, markets will open for the innovative and emerging processes. There will be increasing pressure to break down complex waste streams, with each subsequent stream demanding separate treatment. In addition, a number of technologies have been developed by combining processes directly, or in a treatment train, and these developments are expected to assume increasing importance. However, such concerns as uncertainties due to liability, regulatory approval, price competition, and client approval have limited the application of some of these newer technologies.




Review of International Technologies for Destruction of Recovered Chemical Warfare Materiel


Book Description

The Chemical Weapons Convention requires, among other things, that the signatories to the conventionâ€"which includes the United Statesâ€"destroy by April 29, 2007, or as soon possible thereafter, any chemical warfare materiel that has been recovered from sites where it has been buried once discovered. For several years the United States and several other countries have been developing and using technologies to dispose of this non-stockpile materiel. To determine whether international efforts have resulted in technologies that would benefit the U.S. program, the U.S. Army asked the NRC to evaluate and compare such technologies to those now used by the United States. This book presents a discussion of factors used in the evaluations, summaries of evaluations of several promising international technologies for processing munitions and for agent-only processing, and summaries of other technologies that are less likely to be of benefit to the U.S. program at this time.







Fundamentals of Hazardous Waste Site Remediation


Book Description

Every practicing environmental engineer should already have a firm grasp on the basics of hazardous waste site remediation-the key to confronting a site problem, and devising an effective solution. Since their original introduction to remediation, technology has kept moving ahead with new ideas and procedures. Fundamentals of Hazardous Waste Site Remediation gives environmental professionals immediate access to the basics of the trade, along with information about recent advancements. This comprehensive overview examines the basics of such areas as hazardous materials chemistry, hydrogeology, reaction engineering, and clean-up level development. A chapter on Cost Estimating will be of particular interest to specialists, in light of recent concerns about the increased costs of remediation. After reading each chapter, test your new knowledge with the review problems. As a refresher guide for career environmental engineers, or a helpful tool to newcomers in the field, Fundamentals of Hazardous Waste Site Remediation is a valuable resource for longtime professionals and newcomers alike.













Hazardous Waste Remediation


Book Description
