I have completed the manuscript with the tentative title Radioactive Clouds of Death Over Utah.. From 1950 to the 1958 moratorium on atmospheric testing, the Atomic Energy Commission detonated over 100 atomic bombs at the Nevada Test Site. The inhabitants of St. George, Utah--the so-called downwinders--were repeatedly in the fly zone of these toxic, wind-blown clouds--so much so that St. George became known nationwide as Fallout City, USA. According to the back cover of John Fuller's 1984 best seller, The Day We Bomb Utah: America's Most Lethal Secret, "Within a few years, a plague of cancer and birth defects had ripped through the area---a plague that may have caused the cancer-related deaths of John Wayne and over 100 other cast and crew members of The Conquerer which was filmed only miles from the test site." (Actually, it was filmed only five miles from St. George.) Utah Congressman Jim Matheson alleged in a recent op-ed article in the Deseret News that the horrendous legacy of radioactive fallout is still killing downwinders. "Thousands of citizens throughout the West continue to get sick and die from radiation-exposure-caused illnesses." From an editorial in the February 15, 2001 issue of the Deseret News: ..".the federal government literary sacrificed the health of thousands of unsuspecting Utahan and Nevadans." The focus of Radioactive Clouds of Death Over Utah is to retrospectively consider both the short-term and long-term health effects of radioactive fallout exposure on downwinders from the perspectives of the downwinders, the tort lawyers, the government itself, politicians, producers of five television documentaries, writers of six popular books, hundreds of magazine and newspaper articles and many scientific studies on fallout health effects on Utah residents. Recently the Utah press has featured many fallout-cancer stories giving much weight to anecdotal accounts---downwinders have been featured in the Deseret News 265 times in the last decade. On April 12, 2011 U. S. Senator Tom Udall (D-NM) led a bipartisan group of senators in introducing S-791, the Radiation Exposure Compensation Act Amendments of 2011, which would among other things expand compensation to downwinders in all counties in Idaho, Montana, Colorado, New Mexico, and to areas not now covered in Utah, Nevada, and Arizona. Today, with heightened fears about radiation leaks from damage nuclear power plants in Japan and the possibilities of nuclear terrorism, the discussion of fallout-induced cancers in this book provides valuable basic information about what is known about exposure to radiation and its health risks. A balanced perception of the health risks of ionizing radiation is of great societal importance to issues as varied as radiological terrorism, the future of nuclear power, nuclear waste storage, occupational radiation exposure, the clean-up of nuclear waste sites, medical x-rays (whole-body scanning by computed tomography results in much higher organ doses of radiation than conventional single-film x-rays), manned space exploration, and frequent-flyer risks.

Our interest in the microbial biodegradation of xenobiotics has increased many folds in recent years to find out sustainable ways for environmental cleanup. Bioremediation and biotransformation processes harness the naturally occurring ability of microbes to degrade, transform or accumulate a wide range of organic pollutants. Major methodological breakthroughs in recent years through detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms have provided us unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions. The degradation of a wide spectrum of organic pollutants and wastes discharged into the environment by anthropogenic activities is an emerging need today to promote sustainable development of our society with low environmental impact. Microbial processes play a major role in the removal of recalcitrant compounds taking advantage of the astonishing catabolic versatility of microorganisms to degrade or transform such compounds. New breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are generating vital information which opens a new era providing new insights of metabolic and regulatory networks, as well as clues to the evolution of degradation pathways and to the molecular adaptation strategies to changing environmental conditions. Functional genomic and metagenomic approaches are increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds. New approaches will certainly accelerate the development of bioremediation technologies and biotransformation processes in coming years for natural attenuation of contaminated environments

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution - air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for "zero discharge" can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems has been a major contributing factor to the success of environmental engineering and has accounted in large measure for the establishment of a "methodology of pollution control. " However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

The capability to generate potable water from polluted sources is growing in importance as pharmaceuticals, microplastics and waste permeate our soil. Nanotechnology allows for improvements in water remediation technologies by taking advantage of the unique properties of materials at this small scale.

This book will help the reader expand further into chemical engineering and become a licensed professional engineer (PE), which can offer a tremendous boost to one's career, as there are certain career opportunities available only to licensed engineers. Licensure demonstrates high standards of professionalism, knowledge, and ability. Because of the work experience requirement, PE examinees have generally been out of school for some time. This book summarizes the theoretical background of topics covered in the exam, which will help potential examinees refresh their memories on subjects they may not have been exposed to since their undergraduate classes. Another advantage of using this book to prepare for the PE exam is that two or three "logical distractors" (answers that result from common mistakes) are included among the answer choices for each problem. The solutions to the problems also explain why the logical distractors are incorrect. Research has shown that this is an efficient teaching tool. Thus, the inclusion of these logical distractors and their explanations will give individuals a better foundation in the subject matter in a shorter period of time. Although this book is intended primarily to help engineers prepare for the PE environmental engineering examination, it will also be useful in undergraduate engineering courses that cover environmental engineering topics.

Forming the 10th volume from this successful international conference series, this book features research from scientists, practitioners and other experts working across the field of water resources management. Water is essential for sustaining life on our planet and its uneven distribution is a source of permanent conflict. The growth of human population combined with the irregularity in precipitation and water availability may restrict even further the access to water in certain regions of the world. This problem is made more severe by anthropogenic activities that affect its quality. Moreover, changes in the landscape, use of the land and climate conditions lead to a continuous revaluation of river basin management objectives. This requires the development of better measuring tools as well as the use of increasingly accurate computer software. This volume provides an insight into the state of the art in the current technology, techniques and solutions in sustainable water resources management as they have been developed and applied in different countries. Themes related to water resources include: Water management and planning; Water rights and accessibility; Water markets economics and policies; Climate change; Irrigation; Water resources in arid regions; Ground water; Hydraulic engineering; Trans-boundary water management; Water, food and energy; Water and the community; Integrated water analysis; Wetlands as water sources.

Water is essential for life, a strategic resource for every country and population. Its availability and sanitary safety is highly connected with the health and economy status of population. Burden of disease due to polluted water is a major public health problem throughout the world. Many pollutants in water streams have been identified as toxic and harmful to the environment and human health, and among them arsenic, mercury and cadmium are considered as high priority ones. Providing population with safe drinking water became the priority and at the same time a big challenge for the modern society. Many funding agencies in various countries have assigned a high priority to the envir- mental security and pollution prevention. UN, being one of them, launched the "International Decade for Action: Water for life 2005-2015. " Therefore, today's political and social climate presents an important opportunity to implement principles of sustainable development and to preserve resources essential for future life. This process requires interdisciplinary approach; it is critically important to stimulate interactions between medical doctors, chemists, physicist, materials scientists, engineers and policy makers, which are already experienced in their specific areas. It is also our ethical obligation to preserve existing water resources and existing eco systems enhancing their biodiversity. The NATO Advanced Research Workshop "Water Treatment Te- nologies for the Removal of High-Toxicity Pollutants" took place on September 13-17, 2008 in Ko ice, Slovak Republic."
