Book excerpt: In Situ Bioreclamation: Applications and Investigations for Hydrocarbon and Contaminated Site Remediation is a collection of selected papers submitted by participants to the international symposium ""In Situ and On-Site Bioreclamation"", held in San Diego, California in March 1991. The book consists of articles, which represent a substantial technical contribution, and technical notes, and brief technology descriptions or reports of preliminary or less substantial studies that proposes and exposes various solutions for the biological treatment of contaminated soil, water, and gas. This volume is one of two that represent the most complete and up-to-date set of papers at the time. The book covers the most comprehensive collection of treatises that presents practices in the reversal of damages to the environment. Solutions vary from proven commercially available technologies for some applications, such as reactor treatment of petroleum hydrocarbons in aqueous steams, to fundamental research in others, such as genetic engineering to develop strains of biodegradable xenobiotics. Environmentalists, scientists, students of natural sciences, civil engineers, and those concerned with the preservation and restoration of nature will find this book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: In the late 1970s and early 1980s, our nation began to grapple with the legacy of past disposal practices for toxic chemicals. With the passage in 1980 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, it became the law of the land to remediate these sites. The U. S. Department of Defense (DoD), the nation’s largest industrial organization, also recognized that it too had a legacy of contaminated sites. Historic operations at Army, Navy, Air Force, and Marine Corps facilities, ranges, manufacturing sites, shipyards, and depots had resulted in widespread contamination of soil, groundwater, and sediment. While Superfund began in 1980 to focus on remediation of heavily contaminated sites largely abandoned or neglected by the private sector, the DoD had already initiated its Installation Restoration Program in the mid 1970s. In 1984, the DoD began the Defense Environmental Restoration Program (DERP) for contaminated site assessment and remediation. Two years later, the U. S. Congress codified the DERP and directed the Secretary of Defense to carry out a concurrent program of research, development, and demonstration of innovative remediation technologies. As chronicled in the 1994 National Research Council report, “Ranking Hazardous-Waste Sites for Remedial Action”, our early estimates on the cost and suitability of existing technologies for cleaning up contaminated sites were wildly optimistic. Original estimates, in 1980, projected an average Superfund cleanup cost of a mere $3.

This book was released on 1994-02-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: There may be nearly 300,000 waste sites in the United States where ground water and soil are contaminated. Yet recent studies question whether existing technologies can restore contaminated ground water to drinking water standards, which is the goal for most sites and the result expected by the public. How can the nation balance public health, technological realities, and cost when addressing ground water cleanup? This new volume offers specific conclusions, outlines research needs, and recommends policies that are technologically sound while still protecting health and the environment. Authored by the top experts from industry and academia, this volume: Examines how the physical, chemical, and biological characteristics of the subsurface environment, as well as the properties of contaminants, complicate the cleanup task. Reviews the limitations of widely used conventional pump-and-treat cleanup systems, including detailed case studies. Evaluates a range of innovative cleanup technologies and the barriers to their full implementation. Presents specific recommendations for policies and practices in evaluating contamination sites, in choosing remediation technologies, and in setting appropriate cleanup goals.
Download or read book Principles of Bioreclamation of Contaminated Ground Water and Leachates written by CR. Calabria and published by . This book was released on 1986 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improper disposal of hazardous wastes has resulted in contamination of saturated and unsaturated subsurface materials (the soil/rock/ground-water system) and production of leachates. One of the least appreciated and least applied remedial treatment techniques for these contaminated materials is biological treatment. Such treatment can result in the destruction of hazardous contaminants and may be cheaper than other alternatives. Efficient bioreclamation can occur when a proper, uniform environment for the bacteria, adequate contact between the contaminated materials and the bacteria, and sufficient time to effect the degradation are provided. Maintaining the proper environment (aerobic, anaerobic, or both) includes making sure biodegradable organics are present in sufficient quantity, paying attention to microbial nutrition, keeping the pH in a suitable range, and ensuring that the bacteria can adapt to the presence of toxic substances. Selection of the bioreclamation technique to be used depends on the nature and concentration of the contaminants. The choices for above-ground treatment are suspended-growth and attached/entrapped-growth reactors. Attached/entrapped-growth systems have significant advantages for treating hazardous wastes. The three basic options for in-situ treatment are (1) enhancement of indigenous bacteria, (2) extraction-injection-recycle, and (3) creation of a biologically active barrier. Patience and an appreciation for the keys to efficient biological treatment are required to make these options work.

This book was released on 1997-12-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The limitations of conventional groundwater remediation technologies have led to the development of innovative technologies which may achieve national hazardous waste site remediation goals. Before an innovative technology can be implemented in the field, remedial project managers, regulators and other stakeholders require adequate modeling tools to help assess the applicability of the technology at a particular site. This modeling study investigates how an innovative technology, in situ cometabolic bioremediation, might be implemented to remediate a TCE-contaminated site, under different site conditions. A steady- state model is developed which couples an analytical expression to simulate the effect of flow between multiple pumping and injection wells, with an expression to calculate TCE removal as groundwater circulates through in situ bioreactors established around the injection wells. Varying site conditions and well configurations are investigated to determine their effect on the overall treatment efficiency of a system. A dual screen well design is found to be an effective method for contaminant capture and treatment given typical values of anisotropy. Investigation of a multiple row implementation concept proves it to be an effective configuration for site cleanup. The model is integrated into interactive software which serves as a technology screening tool.
