This book was released on 2014-07-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is one of the most important resources in the world. In many areas, water supplies for industrial, domestic, and agricultural uses are de pendent on groundwater. As an "open" system, groundwater may exchange mass and energy with its neighboring systems (soil, air, and surface water) through adsorption, ion-exchange, infiltration, evaporation, inflow, outflow, and other exchange forms. Consequently, both the quantity and quality of groundwater may vary with environmental changes and human activities. Due to population growth, and industrial and agricultural development, more and more groundwater is extracted, especially in arid areas. If the groundwater management problem is not seriously considered, over extraction may lead to groundwater mining, salt water intrusion, and land subsidence. In fact, the quality of groundwater is gradually deteriorating throughout the world. The problem of groundwater pollution has appeared, not only in developed countries, but also in developing countries. Ground water pollution is a serious environmental problem that may damage human health, destroy the ecosystem, and cause water shortage.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater constitutes an important component of many water resource systems, supplying water for domestic use, for industry, and for agriculture. Management of a groundwater system, an aquifer, or a system of aquifers, means making such decisions as to the total quantity of water to be withdrawn annually, the location of wells for pumping and for artificial recharge and their rates, and control conditions at aquifer boundaries. Not less important are decisions related to groundwater qUality. In fact, the quantity and quality problems cannot be separated. In many parts of the world, with the increased withdrawal of ground water, often beyond permissible limits, the quality of groundwater has been continuously deteriorating, causing much concern to both suppliers and users. In recent years, in addition to general groundwater quality aspects, public attention has been focused on groundwater contamination by hazardous industrial wastes, by leachate from landfills, by oil spills, and by agricultural activities such as the use of fertilizers, pesticides, and herbicides, and by radioactive waste in repositories located in deep geological formations, to mention some of the most acute contamination sources. In all these cases, management means making decisions to achieve goals without violating specified constraints. In order to enable the planner, or the decision maker, to compare alternative modes of action and to ensure that the constraints are not violated, a tool is needed that will provide information about the response of the system (the aquifer) to various alternatives.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater and Surface Water Pollution contains almost all the technical know-how required to clean up our water supply. It provides a survey of up-to-date technologies for remediation, as well as a step-by-step guide to pollution assessment for both ground and surface waters. The book defines groundwater, aquifers and surface water and discusses the physical properties of soils, liquids, vadose zones and aquifers. It emphasizes controlling nonpoint source pollution, best management practices, and an integrated management approach. The editors cover not only engineering but also legal, medical, agricultural, meteorological, biological and other fields of study. They reach beyond the simplistic hydrological cycles usually addressed to the complexities encountered by rapidly-changing land-use patterns. In addition to focusing on causes, effects, and remedies, Groundwater and Surface Water Pollution stresses reuse, recycling, and recovery of resources. Nature does not cause pollution. Through total recycling, we can, like nature, make resources out of wastes. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.

Download or read book Contaminated Water Supplies at Camp Lejeune written by National Research Council and published by National Academies Press. This book was released on 2009-09-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s, two water-supply systems on the Marine Corps Base Camp Lejeune in North Carolina were found to be contaminated with the industrial solvents trichloroethylene (TCE) and perchloroethylene (PCE). The water systems were supplied by the Tarawa Terrace and Hadnot Point watertreatment plants, which served enlisted-family housing, barracks for unmarried service personnel, base administrative offices, schools, and recreational areas. The Hadnot Point water system also served the base hospital and an industrial area and supplied water to housing on the Holcomb Boulevard water system (full-time until 1972 and periodically thereafter). This book examines what is known about the contamination of the water supplies at Camp Lejeune and whether the contamination can be linked to any adverse health outcomes in former residents and workers at the base.

Download or read book Soils and Groundwater Pollution and Remediation written by P. M. Huang and published by CRC Press. This book was released on 1999-07-29 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing population densities of Asia, Africa and Oceania are in conflict with the ecosystem. A growing demand for food and fiber causes agriculture to rely heavily upon chemical fertilization, herbicides and pesticides. Rising industrial output creates higher contamination from cadmium, lead, selenium, and other metals. Soils and Groundwater Remediation explores the toxic levels of metals, radionuclides, inorganics, and anthropogenic organic compounds found in the soils and groundwater of Asia, Africa and Oceania. This 14 chapter book reviews the distribution, transformation, and dynamics of the pollutants. The authors also reflect on the impact of Acid-rain. The contributors to this book are well-known scientists from Japan, China, Korea, Malaysia, New Zealand, Australia, and Kenya. The authors address their findings to researchers, educators, government regulators, and students. As the title suggests, the book is ultimately concerned with remediation. Huang and Iskandar feel "the potential for restoring ecosystem health ... in these areas is enormous." The contributions of Soils and Groundwater Remediation will bring science closer to achieving that possibility.
Download or read book Groundwater Pollution Aquifer Recharge and Vulnerability written by N. S. Robins and published by Geological Society of London. This book was released on 1998 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary groundwater management issue in many countries today is pollution. This may derive from a point source, perhaps a leaking solvent store at a factory, or it may be diffuse, such as the threat posed by the use of agricultural fertilisers and pesticides. The key to understanding the transport of a pollutant from the ground surface or near surface into an aquifer is an understanding of recharge. In turn, this allows the vulnerability of aquifers to pollution to be classified and appropriate land zones to be defined. Land zonation of different classes of aquifer vulnerability is a valuable tool for management and planning. In this volume the recent developments within the interlinked areas of groundwater pollution, aquifer recharge and vulnerability are set against the current groundwater protection policies of the UK amd Republic Ireland.
