This book was released on 2012-12-06 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technology transfer has played an increasingly important role in historic preservation during the latter half of the twentieth century, a situation attested to by the undertaking of an important congressional study in 1986 that assessed the role of federal agencies in the field. In this book leading researchers update the earlier findings and contribute state-of-the-art reviews and evaluations of technological progress in their areas of expertise.

Available in PDF, EPUB and Kindle. Book excerpt: This book, the result of a congressionally mandated study, examines the adequacy of the regulatory framework for mining of hardrock mineralsâ€"such as gold, silver, copper, and uraniumâ€"on over 350 million acres of federal lands in the western United States. These lands are managed by two agenciesâ€"the Bureau of Land Management in the Department of the Interior, and the Forest Service in the Department of Agriculture. The committee concludes that the complex network of state and federal laws that regulate hardrock mining on federal lands is generally effective in providing environmental protection, but improvements are needed in the way the laws are implemented and some regulatory gaps need to be addressed. The book makes specific recommendations for improvement, including: The development of an enhanced information management system and a more efficient process to review new mining proposals and issue permits. Changes to regulations that would require all mining operations, other than "casual use" activities that negligibly disturb the environment, to provide financial assurances for eventual site cleanup. Changes to regulations that would require all mining and milling operations (other than casual use) to submit operating plans in advance.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the results of a study commissioned by Congress estimating the future costs of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, commonly known as the Superfund program. The study projects the cost of activities such as cleaning up sites on the EPA's National Priorities List, conducting emergency response and removal actions, performing five-year reviews, and administering the program. c.

Download or read book Spanish Colonial Tucson written by Henry F. Dobyns and published by Century Collection. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "[Dobyns] has written a fascinating account of the ethnic development of early Tucson. Using a variety of methods and sources, he reveals how Spaniards, mestizos from New Spain, and Native Americans from many tribes laid the ethnic foundations for the modern city. The book also provides much insight into the general history of Spanish colonial society as it evolved in the Tucson area to 1821. . . . Dobyns, utilizing previously unpublished primary sources, allows the early inhabitants of the Tucson area to speak for themselves, and their comments add much to a very colorful and exciting but often grim story. . . . And his penetrating look at the ethnic development of early Tucson should attract attention from anyone interested in a better understanding of how the nation as a whole achieved its multi-cultural character." --The Journal of American History

Download or read book A Numerical Investigation of Metabolic Reductive Dechlorination in DNAPL Source Zones written by John Anthony Christ and published by . This book was released on 2005 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most intractable environmental remediation problems are those involving the release of dense non-aqueous phase liquids (DNAPLs), such as chlorinated solvents, to the subsurface. Research efforts have focused on the use of numerical models to investigate reductions in contaminant concentrations due to partial mass removal and improvements in the performance of complementary source zone remediation technologies. Previous numerical investigations, however, have been limited to two-dimensional systems. Furthermore, a lack of models capable of simulating the most promising complementary technology, metabolic reductive dechlorination, has limited its application. This work developed and applied compositional multiphase numerical simulators to examine the influence of dimensionality (two-dimensions versus three-dimensions) on DNAPL source zone simulations and to investigate the benefits of stimulating metabolic reductive dechlorination at a chlorinated ethene-DNAPL contaminated site. Results from the dimensionality investigation showed that the simulation of DNAPL migration, entrapment, and dissolution in two dimensions provided reasonable approximations to the behavior simulated in three dimensions. Commonly employed saturation distribution and mass recovery metrics were approximately equivalent. Flux- averaged concentrations simulated in two dimensions, however, tended to be three to four times higher than those simulated in three dimensions. This difference was attributed to dilution at the down gradient boundary. An alternative metric, mass flux reduction, however, yielded better agreement.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cultural Resource Management (CRM) refers to the discovery, evaluation, and preservation of culturally significant sites, focusing on but not limited to the archaeological and historical. CRM stems from the National Historic Preservation Act, passed in 1966. In 1986, archaeologists reviewed the practice of CRM in the Great Basin. They concluded that it mainly was a system of finding, flagging, and avoiding -- a means of keeping sites and artifacts safe. Success was measured by counting the number of sites recorded and acres surveyed"--Provided by publisher.
