Book Description
Americans drink many gallons of tap water every day, but many of them question the safety of tap water every day as well. In fact, devices have been created to filter tap water directly before reaching cups. It's true; however, that the provision and management of safe drinking water throughout the United States have seen triumphs in public health since the beginning of the 20th century. Although, advances in water treatment, source water protection efforts, and the presence of local, state, and federal regulatory protection have developed over the years, water in the United States still contain chemical, microbiological, and other types of contaminants at detectable and at times harmful levels. This in addition to the growth of microbial pathogens that can resist traditional water treatment practices have led to the question: Where and how should the U.S. government focus its attention and limited resources to ensure safe drinking water supplies for the future? To deal with these issues the Safe Drinking Water Act (SDWA) Amendments of 1996 Safe included a request that the U.S. Environmental Protection Agency (EPA) publish a list of unregulated chemical and microbial contaminants and contaminant groups every five years that are or could pose risks in the drinking water of public water systems. The first list, called the Drinking Water Contaminant Candidate List (CCL), was published in March 1998. The main function of the CCL is to provide the basis for deciding whether to regulate at least five new contaminants from the CCL every five years. However, since additional research and monitoring need to be conducted for most of the contaminants on the 1998 CCL, the list is also used to prioritize these related activities. Classifying Drinking Water Contaminants for Regulatory Consideration is the third report by the Committee on Dinking Water Contaminants with the purpose of providing advice regarding the setting of priorities among drinking water contaminants in order to identify those contaminants that pose the greatest threats to public health. The committee is comprised of 14 volunteer experts in water treatment engineering, toxicology, public health, epidemiology, water and analytical chemistry, risk assessment, risk communication, public water system operations, and microbiology and is jointly overseen by the National Research Council's (NRC'S) Water Science and Technology Board and Board on Environmental Studies and Toxicology. In this report the committee needed to readdress its second report as well as explore the feasibility of developing and using mechanisms for identifying emerging microbial pathogens for research and regulatory activities. The promotion of public health remains the guiding principle of the committee's recommendations and conclusions in this report.

Book Description
This volume presents a unique and comprehensive glimpse of current and emerging issues of concern related to potable water. The themes discussed include: (1) historical perspective of the evolution of drinking water science and technology and drinking water standards and regulations; (2) emerging contaminants, water distribution problems and energy demand for water treatment and transportation; and (3) using alternative water sources and methods of water treatment and distribution that could resolve current and emerging global potable problems. This volume will serve as a valuable resource for researchers and environmental engineering students interested in global potable water sustainability and a guide to experts affiliated with international agencies working toward providing safe water to global communities.

Book Description
Microbiology of Drinking Water Production and Distribution addresses the public health aspects of drinking water treatment and distribution. It explains the different water treatment processes, such as pretreatment, coagulation, flocculation, sedimentation, filtration, disinfection, and their impacts on waterborne microbial pathogens and parasites. Drinking water quality may be degraded in water distribution systems—microorganisms form biofilms within distribution systems that allow them to flourish. Various methodologies have been proposed to assess the bacterial growth potential in water distribution systems. Microbiology of Drinking Water Production and Distribution also places drinking water quality and public health issues in context; it addresses the effect of bioterrorism on drinking water safety, particularly safeguards that are in place to protect consumers against the microbial agents involved. In addition, the text delves into research on drinking water quality in developing countries and the low-cost treatment technologies that could save lives. The text also examines the microbiological water quality of bottled water, often misunderstood by the public at large.

Book Description
Under 1996 amendments to the SDWA, every 5 years the EPA is to determine for at least five contaminants, such as chemicals, whether regulation is warranted, considering those that present the greatest public health concern. Since 1996, EPA had not recommended any new contaminants for regulation until Feb. 2011, when it reversed its controversial 2008 preliminary decision to not regulate perchlorate, an ingredient in rocket fuel and other products. This report: (1) evaluates the extent to which EPA's implementation of the 1996 amendments has helped assure the public of safe drinking water; and (2) reviews the process and scientific analyses used to develop the 2008 regulatory determination on perchlorate. Illus. A print on demand report.

Book Description
Endocrine Disruptors in the Environment A concise and engaging overview of endocrine disruption phenomena that brings complex concepts within the reach of non-specialists For most of the last decade, the science of endocrine disruption has evolved with more definitive evidence of its damaging potential to health and environment. This book lists the major environmental chemicals of concern and their mechanism of endocrine disruption including remedial measures for them. Divided into three parts, Endocrine Disruptors in the Environment begins with an overview of the endocrine system and endocrine disruptors, discussing their salient features and presenting a historical perspective of endocrine disruption phenomena. It then goes on to cover hormone- signaling mechanisms, followed by various broad classes of putative endocrine disruptors, before introducing readers to environmental epigenetic modifications. Part two of the book focuses on removal processes of various EDCs by biotic and abiotic transformation/degradation. The last section consists of four chapters embracing themes on finding solutions to environmental EDCs—including their detection, regulation, replacement, and remediation. Endocrine Disruptors in the Environment is the first book to detail the endocrine effects of several known environmental contaminants and their mechanism of endocrine disruption. Additionally, it: Covers both the chemistry and biology of endocrine disruption and compiles almost all the known endocrine disrupting environmental chemicals and their mechanisms of toxicity Addresses policy and regulatory issues relevant to EDCs including scientific uncertainty and precautionary policy Brings forth the use of Green Chemistry principles in avoiding endocrine disruption in the designing and screening for safer chemicals and remediation of the EDCs in aquatic environment Includes a useful glossary of technical terms, a list of acronyms, topical references, and a subject index Endocrine Disruptors in the Environment is an ideal book for environmental chemists and endocrine toxicologists, developmental biologists, endocrinologists, epidemiologists, environmental health scientists and advocates, and regulatory officials tasked with risk assessment in environment and health areas.
