Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Located in Antrim County, Michigan between the coasts of Torch Lake and Lake Michigan is a hydrocarbon plume that has impacted surrounding residential wells. The plume is comprised of benzene, toluene, ethylbenzene, and xylenes (BTEX) and primarily resides in the shallowest groundwater aquifer. The plume is suspected of having originated from an underground storage container that was removed in 1979. A conceptual model was developed for the site, comprising of a simplified hydrogeological model. Groundwater modeling was performed using Aquaveo's groundwater modeling software (GMS). PEST parameter calibration was performed on the hydraulic conductivity and recharge values using data from surrounding wells. These values were then used to create a reasonable steady-state regional flow model. The groundwater flow code MODFLOW was used to simulate the steady-state flow model. The use of MT3DMS simulated the fate and transport of the BTEX to inform remediation design. The model simulated natural attenuation, air injection, and enhanced microbial bioremediation (EMB) to project aquifer behavior and contaminant degradation for each remediation technique. Results showed that EMB degraded the plume the lowest, to 2 mg/L after 91 days. While modeling can be a time-efficient and cost-saving technique, it should be coupled with value engineering and site investigation when designing a remediation system.

Download or read book Diffuse Pollution written by N. Campbell and published by IWA Publishing. This book was released on 2005-02-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffuse (non-point source) pollution is increasingly being recognised as a major source of water quality problems in both surface and ground water. Indeed, as pollution resulting from point sources is reduced by the efforts of regulators, diffuse sources frequently remain as the dominant source of pollution. The book is an introductory text covering the nature, causes and the significance of diffuse pollution of both urban and rural origin. Best management practices to tackle the problems are examined as are the ways in which the adoption of such practices may be brought about. Use is made of case studies from several countries to examine the strengths and weaknesses of various approaches. Diffuse Pollution covers both urban and rural sources. Urban sources include run-off from impermeable surfaces of roads, industrial areas and housing which may be contaminated by hydrocarbons, heavy metals, organic chemicals and other undesirable substances. Rural sources include water containing pollutants arising from agriculture and forestry such as plant nutrients, pesticides, microbes and soil itself. This concise book will prove useful to practitioners in the field of pollution control both in an urban and a rural environment, to regulators, to researchers new to the field, and to academics and students. An extensive reference section aids the reader in exploring the subject further.

Download or read book Groundwater Resources of the World and Their Use written by Igorʹ Semenovich Zekt︠s︡er and published by . This book was released on 2004 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph represents many years of groundwater data accumulation by a large number of noted hydrogeologists located throughout the world. It represents a multicultural approach to groundwater resources and their use. As a result, many of the fundamental concepts in hydrogeology are interpreted slightly differently in other countries. In fact, there are a number of hydrogeologic phenomena introduced that for the most part have not been presented internationally. Since various cultures review the science of hydrogeology with their own nuances, a substantial effort was made to provide classic references in the science of hydrogeology. The focus of the monograph was to present data and scientific principals, which are relevant to groundwater use in each of the countries. This monograph represents a major undertaking by hydrologists and hydrogeologists around the world. Although the fundamental groundwater resource data may change slowly over time, the groundwater use data is rapidly changing. Consulting hydrogeologists, engineers, chemists, geologists, biologists, health officials, and government environmental administrators will find this baseline document of substantial value. It is fully anticipated that this book will serve as the first addition of a series on groundwater resources of the world and their use.

This book was released on 2019-08-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book international experts discuss the state-of-the-art in the biological degradation of hydrocarbons to meet remedial or disposal goals. The work focuses on practical applications, often on globally important scales including the remediation of some of the world’s largest crude oil spills. Other related chapters discuss important implications of microbial transformation of hydrocarbons, including treatment of high fat processing wastes, impacts of microbial biodegradation activity on industrial processes, and the implications of microbial oil degradation in relation to modern oil extraction processes like hydraulic fracturing of shales and extraction of oil sands.
Download or read book Alternatives for Ground Water Cleanup written by National Research Council and published by National Academies Press. This book was released on 1994-02-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: There may be nearly 300,000 waste sites in the United States where ground water and soil are contaminated. Yet recent studies question whether existing technologies can restore contaminated ground water to drinking water standards, which is the goal for most sites and the result expected by the public. How can the nation balance public health, technological realities, and cost when addressing ground water cleanup? This new volume offers specific conclusions, outlines research needs, and recommends policies that are technologically sound while still protecting health and the environment. Authored by the top experts from industry and academia, this volume: Examines how the physical, chemical, and biological characteristics of the subsurface environment, as well as the properties of contaminants, complicate the cleanup task. Reviews the limitations of widely used conventional pump-and-treat cleanup systems, including detailed case studies. Evaluates a range of innovative cleanup technologies and the barriers to their full implementation. Presents specific recommendations for policies and practices in evaluating contamination sites, in choosing remediation technologies, and in setting appropriate cleanup goals.

Download or read book Natural Zeolites written by David L. Bish and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 45 of Reviews in Mineralogy and Geochemistry is a new and expanded update of Volume 4 from 1977. Most of the material in this volume is entirely new, and Natural Zeolites: Occurrence, Properties, Applications presents a fresh and expanded look at many of the subjects contained in Volume 4. There has been an explosion in our knowledge of the crystal chemistry and structures of natural zeolites (Chapters 1 and 2), due in part to the now-common Rietveld method that allows treatment of powder diffraction data. Studies on the geochemistry of natural zeolites have also greatly increased, partly as a result of the interests related to the disposal of radioactive wastes, and Chapters 3, 4, 5, 13, and 14 detail the latest results in this important area. Until the latter part of the 20th century, zeolites were often looked upon as a geological curiosity, but they are now known to be widespread throughout the world in sedimentary and igneous deposits and in soils (Chapters 6-12). The application of natural zeolites has greatly expanded since the first zeolite volume. Chapter 15 details the use of natural zeolites for removal of ammonium ions, heavy metals, radioactive cations, and organic molecules from natural waters, wastewaters, and soils. Similarly, Chapter 16 describes the use of natural zeolites as building blocks and cements in the building industry, Chapter 17 outlines their use in solar energy storage, heating, and cooling applications, and Chapter 18 describes their use in a variety of agricultural applications, including as soil conditioners, slow-release fertilizers, soil-less substrates, carriers for insecticides and pesticides, and remediation agents in contaminated soils.
