Municipal Wastewater Treatment


Book Description

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.

Hunting and Fishing in the New South


Book Description

This innovative study re-examines the dynamics of race relations in the post–Civil War South from an altogether fresh perspective: field sports. In the late nineteenth and early twentieth centuries, wealthy white men from Southern cities and the industrial North traveled to the hunting and fishing lodges of the old Confederacy—escaping from the office to socialize among like-minded peers. These sportsmen depended on local black guides who knew the land and fishing holes and could ensure a successful outing. For whites, the ability to hunt and fish freely and employ black laborers became a conspicuous display of their wealth and social standing. But hunting and fishing had been a way of life for all Southerners—blacks included—since colonial times. After the war, African Americans used their mastery of these sports to enter into market activities normally denied people of color, thereby becoming more economically independent from their white employers. Whites came to view black participation in hunting and fishing as a serious threat to the South’s labor system. Scott E. Giltner shows how African-American freedom developed in this racially tense environment—how blacks' sense of competence and authority flourished in a Jim Crow setting. Giltner’s thorough research using slave narratives, sportsmen’s recollections, records of fish and game clubs, and sporting periodicals offers a unique perspective on the African-American struggle for independence from the end of the Civil War to the 1920s.







Gene Drives on the Horizon


Book Description

Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.







The Subterranean Forest


Book Description

This work studies the historical transition from the agrarian solar energy regime to the use of fossil energy, which has fuelled the industrial transformation of the last 200 years. The author argues that the analysis of historical energy systems provides an explanation for the basic patterns of different social formations. It is the availability of free energy that defines the framework within which socio-metabolic processes can take place. This thesis explains why the industrial revolution started in Britain, where coal was readily available and firewood already depleted or difficult to transport, whereas Germany, with its huge forests next to rivers, was much longer dependent on a traditional solar energy regime."
