Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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 or read book The Nature and Pace of Change in American Indian Cultures written by R. Michael Stewart and published by Penn State Press. This book was released on 2016-03-31 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three thousand to four thousand years ago, the Native Americans of the mid-Atlantic region experienced a groundswell of cultural innovation. This remarkable era, known as the Transitional period, saw the advent of broad-bladed bifaces, cache blades, ceramics, steatite bowls, and sustained trade, among other ingenious and novel objects and behaviors. In The Nature and Pace of Change in American Indian Cultures, eight expert contributors examine the Transitional period in Pennsylvania and posit potential explanations of the significant changes in social and cultural life at that time. Building upon sixty years of accumulated data, corrected radiocarbon dating, and fresh research, scholars are reimagining the ancient environment in which native people lived. The Nature and Pace of Change in American Indian Cultures will give readers new insights into a singular moment in the prehistory of the mid-Atlantic region and the daily lives of the people who lived there. The contributors are Joseph R. Blondino, Kurt W. Carr, Patricia E. Miller, Roger Moeller, Paul A. Raber, R. Michael Stewart, Frank J. Vento, Robert D. Wall, and Heather A. Wholey.

Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.
