Book excerpt: This report was written for multiple audiences. Each reader will likely approach the subject from a different perspective, seeking different information. The team that developed the document consisted of several technical experts on monitored natural attenuation (MNA) and included participants who were integral in the development of US EPA's chlorinated solvent MNA protocol and the subsequent US EPA and Office of Solid Waste and emergency Response (OSWER) policy directive. The primary assignment to the interdisciplinary team was to generate a summary of the state-of-the-art, particularly for chlorinated solvent applications and to identify high-priority opportunities for advancement. A diverse jury of peers reviewed the draft report; the report was edited in response to their comments.

Book excerpt: The purpose of this book is to help engineers and scientists better understand dense nonaqueous phase liquid (DNAPL) contamination of groundwater and the methods and technology used for characterization and remediation. Remediation of DNAPL source zones is very difficult and controversial and must be based on state-of-the-art knowledge of the behavior (transport and fate) of nonaqueous phase liquids in the subsurface and site specific geology, chemistry and hydrology. This volume is focused on the characterization and remediation of nonaqueous phase chlorinated solvents and it is hoped that mid-level engineers and scientists will find this book helpful in understanding the current state-of-practice of DNAPL source zone management and remediation.

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.

Book excerpt: The overall Monitored Natural Attenuation and Enhanced Passive Remediation (MNA/EPR) Technology Alternative Project is narrowly focused, providing the scientific and policy support to facilitate implementing appropriate passive cleanup and cost effective monitoring strategies leading to responsible completion of active remediation activities at high risk DOE waste sites. MNA/EPR describe natural processes that mitigate exposure and risk and that are self-sustaining once implemented or require minimal adjustments to maintain functionality. The overall MNA/EPR project effort will be performed as a collaboration between DOE science and operations organizations at the target sites along with regulatory agencies, stakeholders, industry, and universities, as identified in the approved Alternative Project Plan. This plan describes the project initiation activities, individual roles and responsibilities, milestones, and budget for the project. A primary product of this project will be a collaboratively developed MNA/EPR protocol that will facilitate widespread use and acceptance. This technical protocol will be developed in collaboration with regulator agencies as input for regulation updates and guidance documents, as appropriate. This plan describes the project initiation activities, individual roles and responsibilities, milestones, and budget for the project.

Book excerpt: The Department of Energy (DOE) is sponsoring an initiative to facilitate efficient, effective and responsible use of Monitored Natural Attenuation (MNA) and Enhanced Passive Remediation (EPR) for chlorinated solvents. This Office of Environmental Management (EM) ''Alternative Project, '' focuses on providing scientific and policy support for MNA/EPR. A broadly representative working group of scientists supports the project along with partnerships with regulatory organizations such as the Interstate Technology and Regulatory Council and the U.S. Environmental Protection Agency (EPA). The initial product of the technical working group was a summary report that articulated the conceptual approach and central scientific tenants of the project, and that identified a prioritized listing of technical targets for field research. This report documented the process in which: (1) scientific ground rules were developed, (2) lines of inquiry were identified and then critically evaluated, (3) promising applied research topics were highlighted in the various lines of inquiry, and (4) these were discussed and prioritized. The summary report will serve as a resource to guide management and decision-making throughout the period of the subject MNA/EPR Alternative Project. To support and more fully document the information presented in the summary report, we are publishing a series of supplemental documents that present the full texts from the technical analyses within the various lines of inquiry (see listing). The following report - documenting our evaluation of the state of the science of the characterization and monitoring process and tools-- is one of those supplemental documents.

Available in PDF, EPUB and Kindle. Book excerpt: Soil and groundwater contamination stemming from the release of various chlorinated compounds into the environment is a significant and difficult site remediation challenge. The articles in this collection discuss the use of aerobic and anaerobic biological degradation to dehalogenate sites contaminated with pesticides and chlorinated solvents such as trichloroethylene, tetrachloroethene, tetrachloromethene, perchloroethylene, carbon tetrachloride, pentachlorophenol, and chlorinated benzene. Bench- and field-scale studies of the biological processes associated with in situ dechlorination of soil and aquifers are described. Discussed are the uses of microcosm studies and numerical simulation of dechlorination to manage system operation. Site characteristics (e.g., hydraulic properties, temperature, nitrogen availability) and their effect on the stability of the methanotrophic community are examined. Methods discussed include the use of air venting, alternative electron donors, biofilm reactors, surfactants, municipal digester sludge, iron enhancement, and sulfate reduction to improve conditions for the microbial consortia that effect dechlorination.

This book was released on 1997 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work implementation plan (WIP), which was prepared by Parsons Engineering Science, Inc. (Parsons ES) under contract with McClellan Air Force Base (AFB), describes the scope of work required for the collection and analysis of data to evaluate intrinsic remediation (sometimes referred to as natural attenuation, intrinsic bioremediation, or passive bioremediation) of groundwater containing chlorinated solvents beneath Investigation Clusters 17, 19, and 21 (ICs 17/19/21). An important component of the intrinsic remediation evaluation will be to assess the potential for natural biodegradation to reduce the toxicity and mobility of site-related contamination. The term "natural biodegradation" as used in this WIP refers to the biodegradation of chlorinated solvents by indigenous microorganisms without an engineered system. The conditions that allow for the biodegradation processes to occur have been largely determined by the manmade conditions specific to groundwater beneath ICs 17/19/21, namely the co-disposal of fuels with the chlorinated solvents.

This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most powerful and promising strategies for optimizing environmental restoration is the use of combinations of technologies rather than a single technology to reach the target cleanup goals. The U.S. Department of Energy (DOE) is actively working to clean up legacy contamination from its operations. Notably, DOE is responsible for the cleanup of many sites where the contamination includes chlorinated solvents (or chlorinated volatile organic contaminants (CVOCs)). At some sites, groundwater plumes containing CVOCs tend to become relatively large. Estimates for times to remediate sites often ranges up to 100s of years for these large plumes. As a result, the CVOC plumes are a concern to DOE, regulators and stakeholders. In response to this challenge, DOE initiated a project to ''provide the technical and policy support to facilitate implementing appropriate passive cleanup ... leading to responsible completion of active remediation activities at high risk DOE waste sites.'' A combined approach benefits from the ability to match the invasiveness and aggressiveness of the remedial action to the amount of contamination and level of risk. This matching process is particularly important for recalcitrant contaminants such as chlorinated solvents. Highly contaminated areas justify more intense remediation action(s) while minimally contaminated areas are suited to natural or even passive methods. A logical extension of this concept is the need to transition technologies through time as sites become cleaner. The extended approach, sometimes described as a ''technology train, '' responds to changing conditions with the goal of optimizing cleanup.

This book was released on 1996 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several years remediation by natural attenuation has become increasingly accepted as a remedial alternative for organic compounds dissolved in groundwater. The United States Environmental Protection Agency (USEPA) defines natural attenuation as (OSWER, 1996): The term 'Natural Attenuation' refers to naturally-occurring processes in soil and groundwater environments that act without human intervention to reduce the mass, toxicity, mobility, volume, or concentration of contaminants in those media. These in-situ processes include biodegradation, dispersion, dilution, adsorption, volatilization, and chemical or biological stabilization or destruction of contaminants. In practice, natural attenuation also is referred to by several other names, such as intrinsic remediation, intrinsic bioremediation, natural restoration, or passive bioremediation. The goal of any site characterization effort is to understand the fate and transport of the contaminants of concern over time in order to assess any current or potential threat to human health or the environment. Natural attenuation processes, such as biodegradation, can often be dominant factors in the fate and transport of contaminants. Thus, consideration and quantification of natural attenuation is essential to a more thorough understanding of contaminant fate and transport.
