Book Description
This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Description
Water quality of pit lakes is one of the most critical environmental issues facing the global mining industry. As ore grades decrease and operators strive to improve efficiency, the number of active pit mines will continue to outpace their underground counterparts in the years ahead. How will these water resources be protected for future generations while the mining industry continues to meet society's growing demands for raw materials? The key to solving this dilemma is accurately predicting the water quality in advance of open pit mining. That's the purpose of Mine Pit Lakes. The third in a series of six handbooks by the Acid Drainage Technology Initiative--Metal Mining Sector (ADTI-MMS), this volume includes the latest thinking from dozens of internationally respected experts from Canada, Germany, Australia, and the United States. You'll learn both the theory and science of predicting pit lake water quality and get insights into the best practices of pit lake management. This book is an indispensable resource for mining professionals and environmental regulators who are considering new open pit mines or are developing monitoring programs or closure strategies for existing ones.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
This edition of "The Canadian Encyclopedia is the largest, most comprehensive book ever published in Canada for the general reader. It is COMPLETE: every aspect of Canada, from its rock formations to its rock bands, is represented here. It is UNABRIDGED: all of the information in the four red volumes of the famous 1988 edition is contained here in this single volume. It has been EXPANDED: since 1988 teams of researchers have been diligently fleshing out old entries and recording new ones; as a result, the text from 1988 has grown by 50% to over 4,000,000 words. It has been UPDATED: the researchers and contributors worked hard to make the information as current as possible. Other words apply to this extraordinary work of scholarship: AUTHORITATIVE, RELIABLE and READABLE. Every entry is compiled by an expert. Equally important, every entry is written for a Canadian reader, from the Canadian point of view. The finished work - many years in the making, and the equivalent of forty average-sized books - is an extraordinary storehouse of information about our country. This book deserves pride of place on the bookshelf in every Canadian Home. It is no accident that the cover of this book is based on the Canadian flag. For the proud truth is that this volume represents a great national achievement. From its formal inception in 1979, this encyclopedia has always represented a vote of faith in Canada; in Canada as a separate place whose natural worlds and whose peoples and their achievements deserve to be recorded and celebrated. At the start of a new century and a new millennium, in an increasingly borderless corporate world that seems ever more hostile to nationaldistinctions and aspirations, this "Canadian Encyclopedia is offered in a spirit of defiance and of faith in our future. The statistics behind this volume are staggering. The opening sixty pages list the 250 Consultants, the roughly 4,000 Contributors (all experts in the field they describe) and the scores of researchers, editors, typesetters, proofreaders and others who contributed their skills to this massive project. The 2,640 pages incorporate over 10,000 articles and over 4,000,000 words, making it the largest - some might say the greatest - Canadian book ever published. There are, of course, many special features. These include a map of Canada, a special page comparing the key statistics of the 23 major Canadian cities, maps of our cities, a variety of tables and photographs, and finely detailed illustrations of our wildlife, not to mention the colourful, informative endpapers. But above all the book is "encyclopedic" - which the "Canadian Oxford Dictionary describes as "embracing all branches of learning." This means that (with rare exceptions) there is satisfaction for the reader who seeks information on any Canadian subject. From the first entry "A mari usque ad mare - "from sea to sea" (which is Canada's motto, and a good description of this volume's range) to the "Zouaves (who mustered in Quebec to fight for the beleaguered Papacy) there is the required summary of information, clearly and accurately presented. For the browser the constant variety of entries and the lure of regular cross-references will provide hours of fasination. The word "encyclopedia" derives from Greek expressions alluding to a grand "circle of knowledge." Our knowledge has expandedimmeasurably since the time that one mnd could encompass all that was known.Yet now Canada's finest scientists, academics and specialists have distilled their knowledge of our country between the covers of one volume. The result is a book for every Canadian who values learning, and values Canada.
