Since that time,substantial research efforts have been focused on developing new and
3、innovative technolo-gies and management approaches to clean up organic-contaminated sites. With the develop-ment of new and effective technologies, current research efforts are now more focused onrisk assessment and management at contaminated sites, and remediation in complex geolog-ical environment
4、s. Although research, technology transfer, and public education have beenactive links of the overall effort, still there is limited technology transfer and understandingof common remediation technologies and corresponding analysis among practitioners andmanagers. The goal of this monograph is to pro
5、vide some insight into the remediation tech-nologies associated with the saturated subsurface and corresponding analysis. It is intendedto improve the understanding of both existing practitioners and beginning engineers, geolo-gists, water chemists, and biologists.Library of Congress Cataloging-in-P

The de
40、tection of large-scalegroundwater contamination in the United States in the early to mid-1970sbrought about the implementation of two important federal acts: theResources Conservation and Recovery Act of 1976 (RCRA) and the Com-prehensive Environmental Response, Compensation, and Liability Act of198
41、0 (CERCLA, or Superfund). With the initiation of these acts, researchrelated to soil and groundwater remediation accelerated and opened thepublic debate on health hazards caused by contaminated drinking water.The detailed investigation of early contaminated groundwater sitesrevealed that hazardous o
42、rganic contaminants ranging from gasoline tochlorinated solvents were responsible for these widespread environmentalproblems. It was also found that these contaminants entered the valuabledrinking water aquifers due to leaks and spills of underground storagetanks and pipelines as well as unauthorize
43、d disposal of hazardous wastes.When large-scale groundwater contamination was first detected, reme-diation technologies were almost nonexistent, except pump-and-treattechnology. Therefore, great emphasis was placed by federal, state, andprivate agencies on developing innovative technologies to treat
44、 contami-nated groundwater so that health risks would be minimized and drinkingwater sources preserved. However, early progress in remediation technol-ogies was slow because of the lack of understanding of the physical,chemical, and biological processes that control the fate and transport oforganic
45、contaminants in the subsurface as well as the complexity of thechemicals themselves. The processes controlling the environmental fate oforganic chemicals in the vadose zone are different from those in the satu-rated zone. Similarly, different organic chemicalsranging from hydro-carbons to dense solv
46、entsreact differently to subsurface conditions.Even in the presence of these difficulties and other limitations, such assubsurface heterogeneity, researchers have developed many innovativetechnologies to remediate aquifers contaminated with hazardous waste.ixx GROUNDWATER CONTAMINATION BY ORGANIC PO
47、LLUTANTSThis monograph highlights some of the important remediation technol-ogies used in the remediation of contaminated aquifers and their associ-ated analysis. Chapter 1 presents models of multiphase flow systems thatare commonly observed in organic-contaminated aquifers. It discusses pre-vious m
48、odeling work to predict flow and transport in multiphase systemsand currently available modeling software for remediation purposes.Chapter 2 deals with a simple screening model available for the flow andtransport of fuel hydrocarbons in aquifers that can be readily used withminimal data. It also dis
49、cusses a field application to describe the applicabil-ity of the model in actual scenarios. Chapter 3 discusses the most popularand oldest remediation technology: pump-and-treat. Although the tech-nology has been known for decades, the limitations of this approach com-pared with more innovative technologies became known only in recentyears. The focus is on these limitations and how they should be consideredin implementing the technology. Chapter 4 deals with one of the mostpromising and cost-effective techno
