This book was released on 2010-09-10 with total page 807 pages. 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 Envir- mental Response, Compensation, and Liability Act (CERCLA), commonly known as Sup- fund, 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 techn- ogies for cleaning up contaminated sites were wildly optimistic. Original estimates, in 1980, projected an average Superfund cleanup cost of a mere $3.

Download or read book Permeable Barriers for Groundwater Remediation written by Arun R. Gavaskar and published by . This book was released on 1998 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the limitations of conventional pump-and-treat systems in treating groundwater contaminants, permeable barriers are potentially more cost-effective than pump-and-treat systems for treating dissolved chlorinated solvent plumes, which may persist in the saturated zone for several decades. Other contaminants, such as chromium or other soluble heavy metals, can also be treated with this technology. Permeable Barriers for Groundwater Remediation discusses the types of permeable barriers, their design and construction, and how they can be monitored to evaluate compliance. It provides practical guidance on reactive media selection, treatability testing, hydrogeologic and geochemical modeling, and innovative installation techniques for the evaluation and application of this promising new technology. The types of permeable barriers discussed include: trench-type and caisson-based reactive cells; innovative emplacements, such as horizontal trenching and jetting; and continuous reactive barriers versus funnel-and-gate systems.
Download or read book Geochemical Modeling for Mine Site Characterization and Remediation written by D. Kirk Nordstrom and published by Society for Mining, Metallurgy & Exploration. This book was released on 2017-10-01 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The single most important factor for the successful application of a geochemical model is the knowledge and experience of the individual(s) conducting the modeling. Geochemical Modeling for Mine Site Characterization and Remediation is the fourth of six volumes in the Management Technologies for Metal Mining Influenced Water series about technologies for management of metal mine and metallurgical process drainage. This handbook describes the important components of hydrogeochemical modeling for mine environments, primarily those mines where sulfide minerals are present—metal mines and coal mines. It provides general guidelines on the strengths and limitations of geochemical modeling and an overview of its application to the hydrogeochemistry of both unmined mineralized sites and those contaminated from mineral extraction and mineral processing. The handbook includes an overview of the models behind the codes, explains vital geochemical computations, describes several modeling processes, provides a compilation of codes, and gives examples of their application, including both successes and failures. Hydrologic modeling is also included because mining contaminants most often migrate by surface water and groundwater transport, and contaminant concentrations are a function of water residence time as well as pathways. This is an indispensable resource for mine planners and engineers, environmental managers, land managers, consultants, researchers, government regulators, nongovernmental organizations, students, stakeholders, and anyone with an interest in mining influenced water. The other handbooks in the series are Basics of Metal Mining Influenced Water; Mitigation of Metal Mining Influenced Water; Mine Pit Lakes: Characteristics, Predictive Modeling, and Sustainability; Techniques for Predicting Metal Mining Influenced Water; and Sampling and Monitoring for the Mine Life Cycle.

Download or read book Natural Attenuation for Groundwater Remediation written by Commission on Geosciences, Environment, and Resources and published by National Academies Press. This book was released on 2000-07-31 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, officials responsible for clean-up of contaminated groundwater have increasingly turned to natural attenuation-essentially allowing naturally occurring processes to reduce the toxic potential of contaminants-versus engineered solutions. This saves both money and headaches. To the people in surrounding communities, though, it can appear that clean-up officials are simply walking away from contaminated sites. When is natural attenuation the appropriate approach to a clean-up? This book presents the consensus of a diverse committee, informed by the views of researchers, regulators, and community activists. The committee reviews the likely effectiveness of natural attenuation with different classes of contaminants-and describes how to evaluate the "footprints" of natural attenuation at a site to determine whether natural processes will provide adequate clean-up. Included are recommendations for regulatory change. The committee emphasizes the importance of the public's belief and attitudes toward remediation and provides guidance on involving community stakeholders throughout the clean-up process. The book explores how contamination occurs, explaining concepts and terms, and includes case studies from the Hanford nuclear site, military bases, as well as other sites. It provides historical background and important data on clean-up processes and goes on to offer critical reviews of 14 published protocols for evaluating natural attenuation.

Download or read book A Geochemical Evaluation of Enhanced In situ Bioremediation of Chlorinated Ethenes in Groundwater written by and published by . This book was released on 2013 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sites impacted with chlorinated solvents present unique technical challenges when compared to most other groundwater contaminants. Chlorinated volatile organic compounds (CVOCs) such as such as tetrachloroethene (PCE), trichloroethene (TCE), or 1,1,1- trichloroethane (1,1,1-TCA) generally do not degrade naturally in the environment. Therefore, more aggressive source depletion methods such as enhanced in-situ bioremediation (EISB) may be implemented to treat the groundwater plume. EISB involves injection of an electron donor to promote reducing conditions followed by inoculation of groundwater with dechlorinating bacteria. When conditions are favorable, the dechlorinating bacteria sequentially remove chlorine ions from the chlorinated solvent compound until an innocuous end product is produced. This process creates unique and dramatic changes in the natural geochemistry of the aquifer system. A CVOC-impacted site located at Naval Air Station North Island (NASNI) was used as a test case for this study. NASNI is an active military base located adjacent to the City of Coronado in San Diego County, California. The site, or Operable Unit 24 (OU 24), is a chlorinated solvent groundwater plume which may have originated from an acid waste pump station associated with a historic industrial waste pipeline. The purpose of this study was to evaluate the geochemical changes that occur during EISB and how they relate to the effectiveness of remediation. An evaluation of the redox conditions present in groundwater and the observed reduction in CVOC concentrations was used to evaluate the effectiveness of EISB. In addition, geochemical modeling was performed to develop an understanding of the effect of redox conditions on observed dissolved inorganic constituent concentrations due to precipitation or dissolution of minerals present in the aquifer. Based on the results of the geochemical evaluation, groundwater generally became more reducing and VOC concentrations decreased following implementation of EISB. In addition, minerals containing Fe, Mn, and SO4 were sensitive to redox transformations. Conversely, Ca, Mg, Na, and some Mn-containing minerals were not sensitive to redox conditions. Reduced minerals FeS, FeS2, and H2S have the potential to precipitate and oxidized Fe and Mn minerals have the potential to dissolve as groundwater becomes more reducing. This can create problems with groundwater treatment systems that expose groundwater to oxygen. When reduced groundwater containing high concentrations of dissolved Fe and Mn is exposed to oxygen, the Fe and Mn hydroxide minerals will precipitate and may foul remediation equipment. Additionally, redox transformations can potentially mobilize toxic metals such as arsenic, chromium, lead, and mercury through oxidation and reduction processes.
Download or read book Groundwater Remediation written by Nicholas P. Cheremisinoff and published by John Wiley & Sons. This book was released on 2017-06-19 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by one of the world's foremost authorities on the subject, this is the most comprehensive and in-depth treatment available to environmental engineers and scientists for the remediation of groundwater, one of the earth's most precious resources. Groundwater is one of the Earth's most precious resources. We use it for drinking, bathing, and many other purposes. Without clean water, humans would cease to exist. Unfortunately, because of ignorance or lack of caring, groundwater is often contaminated through industrialization, construction or any number of other ways. It is the job of the environmental engineer to remediate the contaminated groundwater and make what has been tainted safe again.Selecting the proper remediation strategy and process is the key to moving forward, and, once this process has been selected, it must be executed properly, taking into consideration the costs, the type of contaminants that are involved, time frames, and many other factors. This volume provides a broad overview of the current and most widely applied remedial strategies. Instead of discussing these strategies in a generic way, the volume is organized by focusing on major contaminants that are of prime focus to industry and municipal water suppliers. The specific technologies that are applicable to the chemical contaminants discussed in different chapters are presented, but then cross-referenced to other chemical classes or contaminants that are also candidates for the technologies. The reader will also find extensive cost guidance in this volume to assist in developing preliminary cost estimates for capital equipment and operations & maintenance costs, which should be useful in screening strategies. The eight chapters cover all of the major various types of contaminants and their industrial applications, providing a valuable context to each scenario of contamination. This is the most thorough and up-to-date volume available on this important subject, and it is a must-have for any environmental engineer or scientist working in groundwater remediation.
