  • My interest in environmental pollution control microbiology began at MIT in 1948 when I realized that very little was known about this vital area of sanitary engineering technology. I became a serious student of environmental pollution control microbiology in 1950 when I began research on the microbiology and the biochemistry of floe-forming bacteria in activated sludge. I must admit that environmental pollution control microbiology has been my area of technical specialization since 1950. It has been a most interesting experience that I have never regretted.

  • The contents of this book are based loosely on presentations at a special symposium, “Application of Interface Science to Environmental Pollution Control,” held as part of the ACS National Meeting in Chicago, August 26–30, 2001. This symposium offered an opportunity for researchers from a range of disciplines to discuss the role of interface science in environmental remediation. The development of an archival book based on this meeting is a timely contribution to a burgeoning area of research that is now attracting the attention of a diverse research community.

  • Assessment of source of air, water, and land pollution - Part II : Approaches for consideration in formulating evironmantal control strategies.The environment is a combination of natural factors and social surrounds the outside of a certain system. They affect this system and identify trends and status of its existence. Environment can be seen as a set, in which the system is considered as a subset. Environment of a system is considered to be interactive with that system

  • Environmental Engineer’s Mathematics Handbook brings together and integrates in a single text the more practical math operations of environmental engineering for air, water, wastewater, biosolids and stormwater. Taking an unusual approach to the overall concept of environmental engineering math concepts, this offers the reader an approach that emphasizes the relationship between the principles in natural processes and those employed in engineered processes.

  • Human activities have a large and important impact on the environment. Naturally occurring elements or compounds are often concentrated and redistributed in the environment through industrial processes, power production, and consumer activity. For example, lead, which is found in naturally occurring mineral deposits, has become a major pollutant through its use in batteries, paints, and gasoline additives.

  • Because of the potential public health implications, the importance of toxic air pollutants in ambient air has been recognized to some degree for many years. Efforts to “regulate” human activities resulting in the production of ambient air pollutants probably date back many centuries, even as the combustion of fossil fuels and air pollution from other organized human activities began having a noticeable impact on the environment.

  • The most significant issues facing mankind today are related to the quality of our environment. Past decisions did not always consider environmental factors as critical elements. However, current decisions made daily should reflect the importance of the environment. All environment-related issues are multidisciplinary, ranging from science and engineering to social, economic, and regulatory issues. Further, these issues are not related to any one region or country, but are global in nature, requiring multidisciplinary, multiorganizational, and multinational educational efforts....

  • There is a new era of global environmental factors that needs to be addressed via sound Corporate Environmental Management. Environmental problems are a key area of concern for the global community in the new 21st century. A sustainable global community is emerging that is geared toward preserving limited resources and the natural ecology, but to do so requires resource conservation and the reduction of environmental pollution loads across all human activities.

  • When one is confronted with a new problem that involves the collection and analysis of data, two crucial questions are: How will using statistics help solve this problem? And, Which techniques should be used? This book is intended to help environmental engineers answer these questions in order to better understand and design systems for environmental protection. The book is not about the environmental systems, except incidentally. It is about how to extract information from data and how informative data are generated in the first place.

  • The occupational and environmental safety and health professions have been on merging paths for several years now. Corporate "down-sizing" or "right-sizing" has resulted in a more streamlined approach to these once very diverse and quite separate disciplines. Although they both may now be practiced in tandem, often by the same individuals, each has evolved and developed as a separate area of study. As such, there are literally thousands of words, terms, and phrases that have specific meanings within their respective disciplines that may not always be clear and simple....

  • Environmental forensics is the systematic examination of environmental information used in litigation. The purpose of this book is to provide a working reference for the practicing environmental attorney or environmental consultant. As a working reference, the topics and examples selected are common denominator issues encountered in environmental litigation; as such, this book is not intended to be a treatise on a particular subject but rather to present information that you will likely encounter.

  • Despite the tremendous progress that has been achieved in water pollution, almost 40% of the U.S. waters that have been assessed by states do not meet water quality goals. About 20,000 water bodies are impacted by siltation, nutrients, bacteria, oxygen depletion substances, metals, habitat alterations, pesticides, and toxic organic chemicals. With pollution from point sources being dramatically reduced, nonpoint source pollution is the major cause of most water that does not meet water quality goals.

  • Significant advances in subsurface containment technology occurred in the 1990s, both with the improvement of the technology and the broader acceptance and applications as a measure for environmental remediation. Since 1995, the U.S. Department of Energy (USDOE), U.S. Environmental Protection Agency (USEPA), and DuPont have collaborated on a series of organized efforts to advance this technology. In that year, these collaborators sponsored an international expert workshop that led to the publication of the first major book on containment technology.

  • Have students think about where they are likely to see litter in the community. Have them think of ways they could educate other students about the problems associated with litter. Divide students into groups of three or four. Have the groups create an environmental awareness poster to be displayed inside the school. If possible, allow the students to decide where the poster should be hung, so that it is likely to be seen by the most students. Next, give each group a map of the school and the...
