DOWNLOAD EBOOKThe book includes six chapters that cover Virginia history from initial settlement through the 20th century plus one that deals with the important role of underwater archaeology. Written by prominent archaeologists with research experience in their respective topic areas, the chapters consider important issues of Virginia history and consider how the discipline of historic archaeology has addressed them and needs to address them . Changes in research strategy over time are discussed , and recommendations are made concerning the need to recognize the diverse and often differing roles and impacts that characterized the different regions of Virginia over the course of its historic past. Significant issues in Virginia history needing greater study are identified.

DOWNLOAD EBOOKThe rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

DOWNLOAD EBOOKAs Metro stretches to Tysons Corner and beyond, this paperback edition features a new preface from the author. Drivers in the nation's capital face a host of hazards: high-speed traffic circles, presidential motorcades, jaywalking tourists, and bewildering signs that send unsuspecting motorists from the Lincoln Memorial into suburban Virginia in less than two minutes. And parking? Don't bet on it unless you're in the fast lane of the Capital Beltway during rush hour. Little wonder, then, that so many residents and visitors rely on the Washington Metro, the 106-mile rapid transit system that serves the District of Columbia and its inner suburbs. In the first comprehensive history of the Metro, Zachary M. Schrag tells the story of the Great Society Subway from its earliest rumblings to the present day, from Arlington to College Park, Eisenhower to Marion Barry. Unlike the pre–World War II rail systems of New York, Chicago, and Philadelphia, the Metro was built at a time when most American families already owned cars, and when most American cities had dedicated themselves to freeways, not subways. Why did the nation's capital take a different path? What were the consequences of that decision? Using extensive archival research as well as oral history, Schrag argues that the Metro can be understood only in the political context from which it was born: the Great Society liberalism of the Kennedy, Johnson, and Nixon administrations. The Metro emerged from a period when Americans believed in public investments suited to the grandeur and dignity of the world's richest nation. The Metro was built not merely to move commuters, but in the words of Lyndon Johnson, to create "a place where the city of man serves not only the needs of the body and the demands of commerce but the desire for beauty and the hunger for community." Schrag scrutinizes the project from its earliest days, including general planning, routes, station architecture, funding decisions, land-use impacts, and the behavior of Metro riders. The story of the Great Society Subway sheds light on the development of metropolitan Washington, postwar urban policy, and the promises and limits of rail transit in American cities.

DOWNLOAD EBOOKProtecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.
