A thorough analysis of public policy and the Clean Water Act'seffect on water quality in the U.S. Using water quality data and historical records from the past 60years, this book presents the measured impact of the 1972 CleanWater Act on domestic waterways-ecologically, politically, andeconomically. Municipal Wastewater Treatment supports thehypothesis that the Act's regulation of wastewater treatmentprocesses at publicly owned treatment works (POTW) and industrialfacilities has achieved significant success. The authors' case ispresented in: * Background information on the history of water pollution controland water quality management * Chapters addressing long-term trends in biochemical oxygen demandloadings from municipal wastewater plants and the "worst-case"dissolved oxygen levels in waterways downstream of point sourcesbefore and after the Clean Water Act * Nine case study assessments of long-term trends of pollutantloading water quality and environmental resources associated withPOTW discharges Using long-term trends in dissolved oxygen as the key indicator ofwater quality improvements, this book provides a detailedretrospective analysis of the effectiveness of the water pollutioncontrol policies and regulations of the 1972 Clean Water Act. Thesuccesses of the Act that have been achieved over the past 30 yearsare placed in the historical context of the "Great SanitaryAwakening" of the 19th century and changes in public policies forwater supply and water pollution control that have evolved duringthe 20th century to protect public health and the intrinsic valueof aquatic resources. Case study sites include the ConnecticutRiver, Hudson-Raritan Estuary, Delaware Estuary, Potomac Estuary,Upper Chattahoochee River, Ohio River, Upper Mississippi River, andWillamette River. Complete with end-of-chapter summaries and conclusions, MunicipalWastewater Treatment: Evaluating Improvements in National WaterQuality is an essential book for engineers, scientists, regulators,and consultants involved in water quality management and wastewatertreatment, as well as students of environmental engineering,environmental science, and public policy.
Sex Estimation of the Human Skeleton is a comprehensive work on the theory, methods, and current issues for sexing human skeletal remains. This work provides practitioners a starting point for research and practice on sex estimation to assist with the identification and analysis of human remains. It contains a collection of the latest scientific research, using metric and morphological methods, and contains case studies, where relevant, to highlight methodological application to real cases. This volume presents a truly comprehensive representation of the current state of sex estimation while also detailing the history and how we got to this point. Divided into three main sections, this reference text first provides an introduction to the book and to sex estimation overall, including a history, practitioner preferences, and a deeper understanding of biological sex. The second section addresses the main methodological areas used to estimate sex, including metric and morphological methods, statistical applications, and software. Each chapter topic provides a review of older techniques and emphasizes the latest research and methodological improvements. Chapters are written by practicing physical anthropologists and also include their latest research on the topics, as well as relevant case studies. The third section addresses current considerations and future directions for sex estimation in forensic and bioarchaeological contexts, including DNA, secular change, and medical imaging Sex Estimation of the Human Skeleton is a one-of-a-kind resource for those involved in estimating the sex of human skeletal remains. - Provides the first comprehensive text reference on sex estimation, with historical perspectives and current best practices - Contains real case studies to underscore key estimation concepts - Demonstrates the changing role of technology in sex estimation
The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool? The Polygraph and Lie Detection puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence. The book looks at: The theory of how the polygraph works and evidence about how deceptivenessâ€"and other psychological conditionsâ€"affect the physiological responses that the polygraph measures. Empirical evidence on the performance of the polygraph and the success of subjects' countermeasures. The actual use of the polygraph in the arena of national security, including its role in deterring threats to security. The book addresses the difficulties of measuring polygraph accuracy, the usefulness of the technique for aiding interrogation and for deterrence, and includes potential alternativesâ€"such as voice-stress analysis and brain measurement techniques.
