This book was released on 2010 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents, for the first time in one place, the results of the latest research regarding water balance covers for solid waste sites, along with case studies drawn from current field testing. Water Balance Covers for Waste Containment: Principles and Practice introduces water balance covers and compares them with conventional approaches to waste containment. The authors give detailed analysis of the fundamentals of soil physics and design issues, introduce applicable ecological concepts and revegetation practices, and then move on to construction, modeling, and maintenance. A viable alternative to conventional landfill cover systems, water balance covers (also known as store-and-release and evapotranspiration covers) cycle water from the soil to the atmosphere during growing season, minimizing the percolation of rainwater through the soil, and thus the production of leachate from land fill contents. This book will be valuable to practicing engineers, as well as regulatory analysts.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to determine the effects of climate, soil, and vegetation on the design of water balance (WB) covers for solid waste landfills in Texas. This study was conducted using water balance software (UNSAT-H model) that considers unsaturated soil hydraulics and plant water uptake. To date, limited research has been conducted for WB covers in Texas. Texas is located in the central region of the United States and encounters approximately nine distinct 5 inch precipitation increments or ranges, unlike any other state in the United States. Texas includes various climate regions and is a favorable choice among other states to determine the effects of climate on the design of WB covers. Approximately 190 solid waste landfills in Texas accepted waste in Fiscal Year 2010 based on information from the Texas Commission on Environmental Quality (TCEQ). This study of the landfills in Texas. The regions were selected based on different climatic conditions: arid, semi-arid, sub-humid, or humid climate. The soils analyzed in this study include clay, silt, clayey sand, and sand, which are usually found during landfill excavation and can potentially be used for WB covers. The clay, silt, and clayey sand soils contain fine-grained particles that provide water storage capacity for WB covers; WB covers rely on: 1) water storage during periods of increased precipitation, and 2) evaporation from surface soils and transpiration through vegetation from deeper soils during drier periods. The design of capillary barriers (sandy soil placed under fine-grained soils to provide capillary break and maximize storage in overlying fine-grained soil) is also analyzed in this study. The vegetation properties analyzed in this study include non-vegetated conditions and vegetated conditions with root depths up to 36 inches. The maximum allowable percolation rate is 4 mm/year in Texas (TCEQ) at the base of the WB cover for determining equivalency to the conventional cover and preventing additional leachate generation, as discussed in this study. An iterative process was used to determine the required design thickness that met the 4 mm/year percolation design standard for all conditions analyzed. The required design thickness is determined from three factors: climate, soil type, and vegetation. The results of this study indicate that more humid climates with greater precipitation require a larger design thickness. Also, the hydraulic conductivity of soil is the most important factor in WB cover design; the CL soil cover required the least design thickness because of its lowest hydraulic conductivity. Vegetated conditions provide for a decrease in required thickness compared to non-vegetated conditions, and the required thickness decreases as deeper roots are modeled.

Download or read book Hard Rock Mine Reclamation written by Bruno Bussière and published by CRC Press. This book was released on 2020-12-09 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hard rock mines have significant effects on the territories where they operate, through both infrastructure construction as well as resource use. Due to their extractive activities, these mines store large quantities of wastes at the surface, which can be both physically and chemically unstable. Reclamation aims to return a mine site to a satisfactory state, meaning that the site should not threaten human health or security, should not generate in the long term any contaminant that could significantly affect the surrounding environment, and should be aesthetically acceptable to communities. This book focuses on the reclamation of waste storage areas, which constitute the main source of pollution during and after mine operations, and especially issues with acid mine drainage and neutral contaminated drainage. Features: Provides fundamental information and describes practical methods to reclaim mine-waste facilities Compares the different methods and illustrates their application at sites through case studies Identifies new reclamation issues and proposes solutions to address them Presents existing and new technologies to reclaim mine waste disposal areas from hard rock mines in different climatic conditions Integrates reclamation into mine operations and long term performance of techniques used through an interdisciplinary approach With mine site reclamation a young and still emerging science, the training needs for professionals and students working in this field are huge. This book is written from an engineering point of view and in it the authors identify new reclamation issues and propose well-tested as well as innovative approaches to addressing them. Students in graduate programs focused on mines and the environment as well as professionals already working in departments related to mine site reclamation will find this book to be a valuable and essential resource.

Download or read book Assessment of the Performance of Engineered Waste Containment Barriers written by National Research Council and published by National Academies Press. This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.

This book was released on 2023-12-15 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containment barrier systems are among the most widely used technologies for remediating contaminated sites. Various structures have been engineered to address site-specific needs, while barrier selection depends largely on whether regulatory requirements are prescriptive, or performance based. This publication provides an introduction to the design and construction of different containment barriers for low-level radioactive waste generated from remediation activities: basal (bottom) liners, final covers, in situ vertical barriers and in situ permeable reactive barriers. Practical aspects of each structure are discussed in theoretical case studies, which allow remediation project designers, implementers and regulators to make more informed decisions about the use of these barriers.
