This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid mine drainage (AMD) is a common byproduct of mining that has severely degraded many streams world-wide. In coal mining, AMD occurs when pyrite contained in coal is exposed to water and air during mining activities and oxidized to release high concentrations of sulfate, metals, and acid into water bodies. Controls on concentration-discharge (CQ) relationships of solutes in AMD-impacted streams remain unclear due to the complicated nature of acid mine drainage systems. For example, streams may receive inputs from multiple sources including runoff, outflow from constructed treatment systems, and abandoned mines that bypass these systems to continue to contaminate the streams. It is important to understand the CQ relationships of contaminants in AMD-impacted streams in order to elucidate contaminant sources and to predict effects on aquatic ecosystems under different flow regimes. Here, we study the CQ behaviors of acid, metals, and sulfate in an AMD-contaminated watershed in northeastern Ohio where a treatment system has been installed to remediate water draining from a mine pool into the stream. The treatment system includes a series of limestone channels and settling ponds designed to increase drainage pH and promote precipitation of Fe- and Mn-oxides. Stream chemistry was measured in samples collected approximately once per day from March through November and hourly during select storm events. Stream flow was measured continuously at the watershed outlet. Contaminant concentrations in the stream generally decreased with increasing stream discharge due to inputs from the treatment system that only occurred at high flow. A decrease in pH from March (~6) through November (~3) was concurrent with a decrease in stream discharge and declining inputs from the treatment system. Correspondingly, AMD-derived contaminants (Fe, Mn, Al) increased in concentration from March through November. These trends reflect mixing of contaminated baseflow and intermittent inputs from the treatment system, indicating that the treatment system is only effective at neutralizing stream acidity and removing metals when flow is present. We determine that constructed treatment systems can act as ephemeral tributaries to the stream and control CQ behavior at the stream outlet.

Download or read book Trace Elements in Soils written by Peter Hooda and published by John Wiley & Sons. This book was released on 2010-04-13 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

Download or read book Investigative Strategies for Lead Source Attribution at Superfund Sites Associated with Mining Activities written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-12-01 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Superfund program of the US Environmental Protection Agency (EPA) was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. Identification of Superfund sites and their remediation is an expensive multistep process. As part of this process, EPA attempts to identify parties that are responsible for the contamination and thus financially responsible for remediation. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.
Download or read book Mine Water written by Paul L. Younger and published by Springer Science & Business Media. This book was released on 2002-02-28 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries. The latter half of the 20th century saw major advances in the reclamation technologies. However, mine water pollution problems have not been addressed. In many cases, polluted mine water long outlives the life of the mining operation. As the true cost of long-term water treatment responsibilities has become apparent, interest has grown in the technologies that would decrease the production of contaminated water and make its treatment less costly. This is the first book to address the mine water issue head-on. The authors explain the complexities of mine water pollution by reviewing the hydrogeological context of its formation, and provide an up-to-date presentation of prevention and treatment technologies. The book will be a valuable reference for all professionals who encounter polluted mine water on a regular or occasional basis.

Download or read book Trace Elements in the Terrestrial Environment written by Domy C. Adriano and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: I intend to fill, with this book, a need that has long been felt by students and professionals in many areas of agricultural, biological, natural, and environmental sciences-the need for a comprehensive reference book on many important aspects of trace elements in the "land" environment. This book is different from other books on trace elements (also commonly referred to as heavy metals) in that each chapter focuses on a particular element, which in tum is discussed in terms of its importance in our economy, its natural occurrence, its fate and behavior in the soil-plant system, its requirement by and detriment to plants, its health limits in drinking water and food, and its origin in the environment. Because of long distance transport to pristine areas of cadmium, lead, copper, and zinc in relatively large quantities, these elements have an extra section on natural ecosystems. A blend of pictorial and tabular data are provided to enhance understanding of the relevant information being conveyed. Since individual chapters are independent of one another, they are arranged alphabetically. However, readers with weak backgrounds in soil science are advised to start with the chapter on zinc, since soil terminology is discussed in more detail here. Sections on sorption, forms and speciation, complexation, and transformations become more technical as soil physical-(bio )chemical phenomena are discussed. The less important "environmental" trace elements are discussed together in the "Other Trace Elements" chapter.

Download or read book The Extractive Metallurgy of Gold written by John C. Yannopoulos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of gold begins in antiquity. Bits of gold were found in Spanish caves that were used by Paleolithic people around 40,000 B.C. Gold is the "child of Zeus," wrote the Greek poet Pindar. The Romans called the yellow metal aurum ("shining dawn"). Gold is the first element and first metal mentioned in the Bible, where it appears in more than 400 references. This book provides the most thorough and up-to-date information available on the extraction of gold from its ores, starting with the miner alogy of gold ores and ending with details of refining. Each chapter con cludes with a list of references including full publication information for all works cited. Sources preceded by an asterisk (*) are especially recom mended for more in-depth study. Nine appendices, helpful to both students and operators, complement the text. I have made every attempt to keep abreast of recent technical literature on the extraction of gold. Original publications through the spring of 1989 have been reviewed and cited where appropriate. This book is intended as a reference for operators, managers, and designers of gold mills and for professional prospectors. It is also designed as a textbook for extractive metallurgy courses. I am indebted to the Library of Engineering Societies in New York, which was the main source of the references in the book. The assistance of my son, Panos, in typing the manuscript is gratefully acknowledged.
