Treatment Wetland Processes, Design, and Implementation presents a state-of-the-art coverage of wetlands applied to the treatment of municipal wastewater, industrial wastewater, combined sewer overflows, sludge and other sources. It builds upon the highly acclaimed previous editions of Treatment Wetlands, but includes a wealth of new information, data, concepts and approaches that are in syntony with the new developments in the field.Focusing on subsurface flow wetlands, the text has been thoroughly revised, fully updated and expanded, including a new and detailed coverage of important treatment wetland variants, such as horizontal flow, vertical flow, French vertical flow, aerated, fill-and-drain, combined sewer overflow and sludge treatment wetlands.Treatment Wetland Processes, Design, and Implementation contains a carefully planned balance between theory and practice, with a clear and didactic presentation of the main concepts, working principles, expected performance, design criteria, construction aspects, and operational guidelines of treatment wetlands with a worldwide perspective on application. The book is an essential source for novice and experienced professionals, researchers, teachers, and students across the globe.KEY FEATURESThe most comprehensive and updated book on subsurface flow treatment wetlandsAvailable in print version and as open-access e-bookWastewater treatment fundamentals applied to treatment wetland process designOver 1,000 pages with information at basic, intermediate, and advanced levelsClear and didactic color artwork, photographs, charts, and summary tablesFully executed practical design examples supported by downloadable spreadsheets

Completely revised and updated, Treatment Wetlands, Second Edition is still the most comprehensive resource available for the planning, design, and operation of wetland treatment systems. The book addresses the design, construction, and operation of wetlands for water pollution control. It presents the best current procedures for sizing these systems, and describing the intrinsic processes that combine to quantify performance. The Second Edition covers:New methods based on the latest researchWastewater characterization and regulatory framework analyses leading to detailed design and economicsState-of-the-art procedures for analyzing hydraulics, hydrology, substrates and wetlands biogeochemistryDefinition of performance expectations for traditional pollutants such as solids, oxygen demand, nutrients and pathogens, as well as for metals and a wide variety of individual organic and inorganic chemicalsDiscussion of methods of configuration, construction, and vegetation establishment and startup considerationsAncillary benefits of human use and wildlife habitatSpecific examples of numerous applicationsExtensive reference base of current information The book provides a complete reference that includes: detailed information on wetland ecology, design for consistent performance, construction guidance and operational control through effective monitoring. Case histories of operational wetland treatment systems illustrate the variety of design approaches presented allowing you to tailor them to the needs of your wetlands treatment projects. The sheer amount of information found in Treatment Wetlands, Second Edition makes it the resource you will turn to again and again.

During the 1980s, the Reagan Administration financed and directed wars against popular movements in El Salvador and Nicaragua that left more than 300,000 dead and countless more wounded. Vowing to block “Soviet expansion,” the U.S. waged a Vietnam-style counterinsurgency against leftist rebels in El Salvador while orchestrating an illegal and covert war to overthrow the Sandinista government in Nicaragua. Some 75,000 died in El Salvador, mostly at the hands of U.S.-backed military and security forces, and more than 30,000 were killed in Nicaragua. Meanwhile, with tacit American support, the Guatemalan military razed hundreds of communities and killed an estimated 200,000 people during a 36-year civil war, including 100,000 Indigenous Mayan villagers.Scott Wallace arrived in Central America in 1983 to cover the conflicts as a freelance “stringer” for CBS News and the Atlanta Journal and Constitution, and he would also later report for Newsweek, The Nation, The Independent, The Guardian, and other news organizations. Seeking to discern the truth in a region riddled with death and deception, Wallace evolved a distinctive style of field reporting that included photography, writing, and broadcast recordings. He stayed in the region throughout the decade, moving back and forth across national boundaries and battlelines to produce a unique body of work that includes the perspectives of opposing sides of the interwoven conflicts as well as their impacts on the noncombatants tragically caught in the middle. He later reported from Afghanistan and Iraq.Situating the exercise of U.S. power on a continuum running from Vietnam through Central America to Iraq and the Middle East, Central America in the Crosshairs of War provides a rare look into the shocking real-life consequences of morally dubious policies while offering a gripping primer for aspiring foreign correspondents and field reporters. As Wallace reminds us, the multiple “troubles” associated today with America’s southern border—among them immigration, drugs, and crime—are in significant measure the result of misadventures undertaken by the U.S. during the administrations of Ronald Reagan and George H. W. Bush. He also shows a continuum in U.S. military affairs, from Vietnam to Central America and the Middle East.
