Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

The carbon dioxide absorption and gas exchange at the sea surface, marine aerosols and their photochemistry, the oceanic carbon cycle as well as biomarkers in marine ecosystems, and related topics are of primary importance for understanding our global ecosystem. The topics addressed in this volume are all stemming from areas which have developed only in the last ten years of research or which have gone into decidedly new directions in that time. In most cases, the recent research has been driven by advances in instrumentation or by large-scale international cooperations. Thus this volume is also aiming at interdisciplinary and international cooperations in the future.

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.

Hydraulic fracturing, commonly referred to as“fracking,” is a technique used by the oil and gasindustry to mine hydrocarbons trapped deep beneath theEarth’s surface. The principles underlying the technology arenot new. Fracking was first applied at the commercial level in theUnited States as early as 1947, and over the decades it has beenapplied in various countries including Canada, the UK, and Russia.The author worked with engineering teams as early as the mid-1970sin evaluating ways to improve oil recovery from this practice. By and large fracking was not an economically competitiveprocess and had limited applications until the early 2000s. Several factors altered the importance of this technology, amongthem being significant technological innovations in drillingpractices with impressive high tech tools for exploration, wellconstruction and integrity, and recovery along with discoveries ofmassive natural gas reserves in the United States and other partsof the world. These factors have catapulted the application of thetechnology to what is best described as the gold rush of the 21stcentury, with exploration and natural gas plays proceeding at apace that seemingly is unrivaled by any historical industrialendeavor. But this level of activity has invoked widespreadcriticism from concerned citizens and environmental groups inalmost every nation across the Globe. This outstanding new volume offers the industry a handbook ofenvironmental management practices that can mitigate risks to theenvironment and, through best practices and current technologies,to conform to the current standards and regulations that are inplace to provide the world with the energy it needs while avoidingenvironmental damage. For the new hire, veteran engineer, andstudent alike, this is a one-of-a-kind volume, a must-have foranyone working in hydraulic fracturing.

The discipline of surface and colloid chemistIy has experienced a considerable resurgence since the early sixties. This perhaps reflects a growing realisation of the wide applicability of modern colloid and surface theory to many important industrial, medical and environmental problems. This increased activity has resulted in a very complex and at times even confusing area of science being consolidated within a firm theoretical framework. The clearer insights gained into the underlying principles have no doubt acted in an autocatalytic manner to stimulate further interest in an expanding range of applications. A good example in the area of environmental chemistry has been the realization of the important role played by colloidal material and surface interactions in natural biogeochemical processes that has been the subject of increasing attention over the last few decades. This is well illustrated by the numerous studies carried out to elucidate the speciation, toxicity, transport and fate of pollutants in aquatic systems. In the vast majority cases these have clearly implicated some involvement of an aSSOciation between the of pollutant (e. g. trace metal, toxic organic compound or nutrient) and a colloidal component (e. g. particle, humic substance, foam). In order to understand these interactions fully and their effect on pollutant mobility it is important to develop a full appreciation of the surface chemistry of these complex systems. Australian SCientists have long been prominent in the area of colloid and surface chemistry particularly dUring the latter half of this century.
