According to the National Resources Defense Council, stormwater runoff rivals or exceeds discharges from factories and sewage plants as a source of pollution throughout the United States. The Environmental Protection Agency identifies urban stormwaters as the second largest source of water quality damage in estuaries and a significant contributor to the damage to lakes, rivers, and bays.

The full impacts of marginal pollution, particularly that caused by uncontrolled overflows, must be recognized now and planning needs to be initiated to improve sewerage sytem efficiencies in order to bring wastewater flows under control. Time is of the essence for municipal programs because corrective action is a time consuming process. Current research and development is elucidating the most efficient and least costly methods needed to restore and maintain water resources.

Based on seminars presented by international experts for the U.S. EPA, Wet-Weather Flow in the Urban Watershed: Technology and Management covers a broad spectrum of urban wet-weather flow management and pollution abatement topics. The topics covered will assist municipal engineers, consultants, and academic researchers with design, cost, and water quality issues.

When a small company dedicated to doing things differently decided some twenty years ago to make as natural a tobacco product as possible, they turned to America's tobacco farmers and proposed an unheard of proposition: How about growing organic tobacco? Today, demand for organic tobacco leaf is doubling each year. But when it was first proposed, there were more than a few skeptics. Now, many are looking at the growing practices and sustainable farming techniques developed by this small group of pioneers. Here's the colorful history behind this new old way of farming. "Organic Tobacco Growing in America" is a quintessential American story of applying vision and values to innovation. More than just a practical guide on how and why to embrace organic growing, this is a story that stretches from its American Indian-inspired beginnings in the windswept high desert of northern New Mexico to the fabled tobacco roads of the southeast. Along the way, meet the growers who learned how organic farming of not just tobacco, but vegetables and other produce as well, is returning the principles of nature back to the family farm. This is a story about the rebirth of a lifestyle-a way of life that once was and now is meant to be again-for a world that yearns for sustainable, earth-friendly farming. Mike Little has been working with tobacco nearly his entire life. Today he is the "master blender" and senior vice president of operations for Santa Fe Natural Tobacco Company (SFNTC). Fielding Daniel also has been working in and around the golden leaf for many years. He is director of leaf for SFNTC and, like Mike, is based in Oxford, North Carolina. Mark Smith, a writer and vice president of communications for SFNTC, has been working with tobacco for the better part of three decades. He is based in Santa Fe, New Mexico. Jim Haskins, with his company, AgriBusiness Communications Group, based in Carrboro, North Carolina, has been writing about tobacco growers for more than ten years for SFNTC. He has produced numerous videos, including "How to Grow Organic Tobacco-the Santa Fe Way."

Als vor 20 Jahren ein kleines Unternehmen, das sich darauf spezialisiert hatte, die Dinge anders zu machen, entschied, das allernaturlichste Tabakprodukt auf der Welt herzustellen, wandte es sich an Amerikas Tabakanbauer und machte ihnen einen beispiellosen Vorschlag: Wie ware es damit, Tabak biologisch anzubauen? Heute verdoppelt sich die Nachfrage nach biologisch angebautem Tabak jahrlich. Aber als der Vorschlag zuerst gemacht wurde, gab es mehr als nur ein paar Skeptiker. Heutzutage zeigen viele Menschen Interesse an den Anbauverfahren und nachhaltigen Anbautechniken, die von dieser kleinen Gruppe von Pionieren entwickelt wurden. Wir bringen Ihnen die abwechslungsreiche Geschichte dieser neuen und doch alten Art der Landwirtschaft naher. Biologischer Tabakanbau in Amerika - eine uramerikanische Geschichte, in der sich Visionen und Werte mit Innovation paaren. Dies ist mehr als nur eine praktische Anleitung zum Wie und Warum des biologischen Anbaus, es ist eine Geschichte, die von den ursprunglichen Anbaumethoden der amerikanischen Ureinwohner in der windgepeitschten Hochebene des nordlichen New Mexico bis hin zu den beruhmten Tobacco Roads des amerikanischen Sudostens reicht. Begegnen Sie den Farmern, die die Erfahrung machten, dass der biologische Anbau von Tabak, Gemuse und anderen Produkten die Prinzipien der Natur wieder auf ihre Familienfarm zuruckbringt. Dies ist eine Geschichte uber die Wiedergeburt einer Lebensweise - eine Lebensweise, die es fruher gab und die nun wieder existieren soll - fur eine Welt, die sich nach nachhaltiger, umweltfreundlicher Landwirtschaft sehnt. Mike Little hat fast sein ganzes Leben lang mit Tabak gearbeitet. Heute ist er der Meistermischer" und Senior Vice President of Operations bei der Santa Fe Natural Tobacco Company (SFNTC). Fielding Daniel hat ebenfalls viele Jahre im und mit Tabak gearbeitet. Er ist Director of Leaf bei der SFNTC und arbeitet, wie Mike, in Oxford, North Carolina. Mark Smith, Schriftsteller und Vice President of Communications bei der SFNTC, arbeitet seit fast drei Jahrzehnten mit Tabak. Er lebt in Santa Fe, New Mexico. Jim Haskins, mit seinem in Carrboro, North Carolina, ansassigen Unternehmen AgriBusiness Communications Group, schreibt fur die SFNTC seit mehr als zehn Jahren Artikel uber Tabakanbauer.

Approximately 15,000 combined sewer overflow events (CSOs) occur annually. During peak storm events they can release about 1.2 trillion gallons of waste and up to 95% of a municipality's raw sewage into surface waters. Although many cities have initiated programs, the CSO problem remains largely unsolved and continues to be a major area of responsibility for environmental professionals, engineers, and public works officials.

Sponsored by the EPA, written by internationally recognized experts, and subjected to extensive peer review, Management of Combined Sewer Overflows provides the latest information on the subject from analysis of contaminants to long-term CSO control plans. Coverage includes:

" CSO analysis and characterization of contaminants
" Analysis and characterization of receiving-water impacts
" Methods of control such as storage, treatment, disinfection, and systems optimization
" Regulations and compliance
" Systems retrofits and upgrades
" Long-term CSO control plans
" Research and design needs

Abatement or prevention of pollution stormwater runoff and CSOs is one of the most challenging areas in the environmental engineering field. The facts of life - from an engineering standpoint - are difficult to face in terms of design and cost. And operational problems can be just as foreboding. A reference for anyone combating urban wet-weather-induced water pollution, Management of Combined Sewer Overflows covers the gamut of engineering requirements, from pollution problem assessment and associated tools, to management and control planning and design.
