Book Description
... Identifies and discusses the major factors affecting well yields with tables of median yields; includes a description and evaluation of well-test methods that can be used to evaluate the yields of bedrock wells; the source and occurrence of water in bedrock and the principal methods of drilling and well construction in MA are also described; nearly 400,000 people in MA, or almost seven percent of the population, obtain drinking water from domestic wells; information in this report will be useful to health officials, homeowners, businesses and well drillers ...

Book Description
Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments; they are commonly encountered in the continental crust. Until now, many geologists have been deterred from working with migmatites because of their complex appearance and an unhelpful non-genetic nomenclature. In his Atlas of Migmatites, Dr. Edward Sawyer provides genetically based definitions and a system of nomenclature with which it will be possible to describe and map migmatites effectively and to understand how combinations of factors and processes produce a bewildering morphological diversity. Migmatites are produced by partial melting; to aid the reader in the identification of migmatites, the author describes and illustrates microstructures that can be used to infer the presence of melt or a melt-producing reaction. He also describes how geochemical data can be used to infer petrological processes involved in migmatite development. This book includes the results from two decades of research in whole-rock geochemistry, partial melting, microstructural analysis and experimental deformation of partially molten rocks. It contains information from an outcrop through to a grain scale. Exceptionally well illustrated, with 272 colour plates and accompanying detailed captions, the Atlas provides descriptions and analyses of migmatites not previously available.

Book Description
The U.S. Ocean Commission Report identified the need for regional ecosystem assessments to support coastal and ocean management. These assessments must provide greater understanding of physical and biological dynamics than assessments at global and national scales can provide but transcend state and local interests. This need and timeliness is apparent for Long Island Sound, where a multi-state regional restoration program is underway for America’s most urbanized estuary. Synthesis of the Long Island Sound ecosystem is needed to integrate knowledge across disciplines and provide insight into understanding and managing pressing issues, such as non-point sources of pollution, coastal development, global climatic change, and invasive species. Currently, there is a need for a comprehensive volume that summarizes the ecological and environmental dynamics and status of Long Island Sound and its myriad ecosystems. It has been 30 years since a comprehensive summary of Long Island Sound was prepared and 50 years since the pioneering work of Gordon Riley. Major advances in estuarine science are providing new insights into these systems, and yet, the condition of many estuaries is in decline in the face of continuing coastal development. There is an opportunity to lay a foundation for integrative coastal observing systems that truly provide the foundation for improved decision-making. This book will provide a key reference of our scientific understanding for work performed over the past three decades and guide future research and monitoring in a dynamic urbanized estuary.

Book Description
In 1957--long before colleges awarded degrees in creative nonfiction and back when newspaper writing's reputation was tainted by the fish it wrapped--Princeton began honoring talented literary journalists. Since then, fifty-nine of the finest, most dedicated, and most decorated nonfiction writers have held the Ferris and McGraw professorships. This monumental volume harbors their favorite and often most influential works. Each contribution is rewarding reading, and collectively the selections validate journalism's ascent into the esteem of the academy and the reading public. Necessarily eclectic and delightfully idiosyncratic, the fifty-nine pieces are long and short, political and personal, comic and deadly serious. Students will be provoked by William Greider's pointed critique of the democracy industry, eerily entertained by Leslie Cockburn's fraternization with the Cali cartel, inspired by David K. Shipler's thoughts on race, unsettled by Haynes Johnson's account of Bay of Pigs survivors, and moved by Lucinda Frank's essay on a mother fighting to save a child born with birth defects. Many of the essays are finely crafted portraits: Charlotte Grimes's biography of her grandmother, Blair Clark's obituary for Robert Lowell, and Jane Kramer's affecting story of a woman hero of the French Resistance. Other contributions to savor include Harrison Salisbury on the siege of Leningrad, Landon Jones on the 1950s, Christopher Wren on Soviet mountaineering, James Gleick on technology, Gloria Emerson on Vietnam, Gina Kolata on Fermat's last theorem, and Roger Mudd on the media. Whether approached chronologically, thematically, randomly, or, as the editors order them, more intuitively, each suggests a perfect evening reading. Designed for students as well as general readers, The Princeton Anthology of Writing splendidly attests to the elegance, eloquence, and endurance of fine nonfiction.

Book Description
Understanding of groundwater flow and solute transport in fractured rocks is vital for analysis of water resources, water quality and environmental protection, geotechnical and engineering projects, and geothermal energy production. This book includes theoretical and practical analyses using numerical modelling, geochemistry, isotopes, aquifer tests, laboratory tests, field mapping, geophysics, geological analyses, and some unique combinations of these types of investigation. Current water resource and geotechnical problems and the techniques now used are also discussed. Aimed at practicing hydrogeologists, engineers, ecologists, resource managers, students and earth scientists.
