An understanding of the fate and behaviour of organic chemicals, such as surfactants, in the environment is a prerequisite for the sustainable development of human health and ecosystems. As surfactants are being produced in huge amounts, it is important to have a detailed knowledge about their lifetime in the environment, their biodegradability in wastewater treatment plants and in natural waters, and their ecotoxicity. Parameters relevant for the assessment of long-term behaviour, such as interactions with hormonal systems need to be understood to avoid unexpected adverse effects to future generations of people and the environment. However, the identification and quantification of commercial surfactants in the environment is made more complicated and cumbersome because they comprise of tens to hundreds of homologues, oligomers and isomers of anionic, nonionic, cationic and amphoteric compounds.The EU-funded PRISTINE project (Priority surfactants and their toxic metabolites in wastewater effluents: An integrated study; ENV4-CT97-0494) provides the basis for the content of this title. It provides policy makers and industry with detailed information on analysis and concentrations of surfactants and their degradation products in the environment.In addition to a general introduction to surfactants, this book comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment. Readers will find all the necessary information for analyzing the different groups of surfactants, with special emphasis on transformation products. Quality assurance is also reported on in detail. Chapters on toxicity and risk assessment are also included and give a complete perspective on the surfactants problem in the aquatic environment. · Presents the finding of EU-funded research into fate and behaviour of organic chemicals in the environment· Comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment· Provides relevant information to all groups working in the field of surfactants

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.

Groundwater treatment is unique. Removing the sources of contamination, as we did when we cleaned a river or lake, is only the first step. A groundwater remediation must include cleaning of the body of water itself, the aquifer. The revised and updated edition of Groundwater Treatment Technology provides a complete review of the technologies developed over the past 10 years for groundwater treatment. It also explains the design techniques that are required to apply those technologies successfully in a groundwater cleanup. Featured areas of coverage include: Specific design methods for the various technologies that are merely described in other publications Physical/chemical and treatability properties of 30 organic compounds that are most often encountered in groundwater situations Detailed strategies for remediation New biological treatment methods Specific data on treatment methods as applied in the field Practical suggestions on applications of technologies for groundwater treatment Drawing on his experience as a designer of over 100 groundwater treatment systems, Evan K. Nyer starts by showing how to develop the data necessary to define what type of treatment is necessary. He then explains how groundwater treatment is unique. Nyer follows with expert accounts of specific treatment technologies. Physical/chemical organic methods such as air stripping, carbon adsorption, and pure compound removal are explored in detail. In addition, new techniques including UV Oxidation and other emerging technologies are explained and directly related to groundwater design situations. An entire chapter is devoted to biological methods, one of the most promising areas for organic groundwater treatment. There is also comprehensive coverage of inorganic methods, that addresses everything from precipitation to solids/liquid separation and advanced ion removal methods. This definitive sourcebook also contains helpful cost factor analyses, plus representative case histories showing how the techniques of groundwater treatment have been applied in the field. Wide-ranging, authoritative, and completely updated, the Second Edition of Groundwater Treatment Technology is essential reading for wastewater engineers, industrial managers, hydrologists, soil experts, government officials, and environmental lawyers who want to keep abreast of the latest developments in this important field.

With an increased demand for wastewater reuse, groundwater recharge with treated wastewater has been practiced across the globe. As a result, groundwater quality deteriorates by emerging micropollutants from various anthropogenic origins, including untreated wastewater, seepage of landfill leachate, and runoff from agricultural lands. The fate of such emerging and geogenic contaminants in subsurface systems, especially in the groundwater, depends on several factors. Physicochemical properties of contaminants such as octanol-water partition coefficient, dissociation constant, water solubility, susceptibility to biodegradation under anaerobic conditions, and environmental persistence under diverse geological and pH conditions play a critical role during subsurface mass flow. Thus, advanced wastewater treatment techniques, followed by implementing stricter guidelines, are some of the measures that can safeguard water resources. This book, in general, gives an understanding of the fate and mitigation strategies for emerging and geogenic contaminants in the groundwater. The first and second sections provide a detailed insight into various removal techniques and mitigation approaches. Possible treatment strategies, including bioremediation and natural attenuation, are also covered in those sections. Environmental assessment, groundwater vulnerability, health effects, and regulations pertaining to various contaminants are systematically presented in the third section.

In this compilation, the authors open with an address of alternative advanced technologies that effectively meet the desired level of removal of recalcitrant contaminants from water. They discuss the advantages and disadvantages of different state of the art technologies, assess the need for further development, as well as estimate the potential for large scale applications based on technological advancement and availability. Next, the book delves into the origin of chitin, which can be traced back to 1811 when it was first discovered in mushrooms by Henri Braconnot while he was Professor of Natural History and Director of the Botanical Gardens at the Academy of Science in France. Twenty years later, chitin was isolated in insects. In 1878, Ledderhose determined that chitin was constructed of glucosamine and acetic acid. The subsequent chapter presents results of an experiment analyzing the concentration of dissolved substances as a major factor that determines the efficiency of membrane separation for wastewater treatment. The results show that selectivity of different types of semi-permeable membranes in a wide range of concentrations can be predicted with sufficient accuracy. Another paper deals with aerobic treatment, i.e. the activated sludge method and the anaerobic process. Activated sludge is the most widely used method to bring about stabilization in wastewater having organic matter constituents. The possibilities of function are analysed in this sludge system, and a short outline is given about the humans plans in the future with connection of the biological waste water treatment. The closing paper discusses the treatment of wastewater from surfactants, as its application has increased markedly both in everyday life and in many industrial branches. Water containing surfactants is fatal for the environment and has a toxic impact on the human body, causing cancerogenic, mutagenic and allergenic effects. Thus, there is a great need for reliable water treatment in chemically developed countries.
