Vertical Barriers in Soil for Pollution Containment
Vertical barriers have evolved over the past fifteen years into a technique that is widely applied to restrict the underground movement of liquid wastes and polluted groundwater. Most...
Impact of Current Regulations on Geotechnical Practice
Enactment of the Resource Conservation and Recovery Act (RCRA), which was intended to provide 'cradle to grave' management of hazardous waste, has caused a greater...
Assessment of Pore Fluid Effects Using Flexible Wall and Consolidation Permeameters
Hydraulic conductivity tests were conducted on compacted soil specimens prepared at activities of 0. 36, 0. 60, 1. 00 and 1. 39 at a fine fraction of 25 percent. Na-montmorillonite, Georgia...
Containment of Low-Level Radioactive Material
The U. S. Department of Energy has completed a short term storage site for the containment of low-level radioactive residues and contaminated soil near Lewiston, New York. The site, known...
Slurry Trench Construction?Collier Road Landfill
The owner of an existing solid waste landfill has undertaken several measures to contain and recover near-surface groundwater at the site, including capping of the site with cohesive soil,...
Landfill Stabilization for Structural Purposes
The insitu stabilization of landfills and waste disposal sites for structural and environmental purposes has recently been accomplished through the application of existing soil stabilization...
Erosion of the Slopes of Gold Tailings Dams
A study has been made of rates of erosion from the slopes of gold-residue dams in the South African Highveld region. Data is available for two years at this time and conclusions must therefore...
Waste Concentration Effects of Grout Barriers
Great concern has developed over hazardous waste sites, particularly in the leaching of the hazardous wastes into groundwater supplies. Many sites that are considered contaminated and...
Use of Geomembranes in Deep Valley Landfills
The installation of geomembranes (synthetic liners) under deep valley landfills of utility and mine waste presents unique problems. Limited data are available concerning geomembranes beneath...
Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...
Reclamation of Athabasca Oil Sand Sludge
The bulk of oil sand tailings (80 to 90%) consists of quartz sand, which is defined to be everything coarser than 44 microns. The other 10 to 20%, termed 'sludge',...
Flow and Mass Transport for Hazardous Waste Liners
Certain aspects of flow and contaminant migration of hazardous liquids through soils are addressed. A fine-grained soil and fluids commonly encountered in hazardous sites, were considered....
Field Measurements of Landfill Surface Settlements
The Collier Road Landfill, located in southeast Michigan, has been accepting industrial and muncipal solid waste since the late 1960's. This existing landfill encompasses...
Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...
Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...
Fly Ash as a Potential Waste Liner
Earthen liners have been widely used to contain toxic and hazardous materials in ponds and landfills. There is close scrutiny over the durability of liners in contact with various wastes...
Plastic Concrete Cutoff Walls
The studies revealed that plastic concrete can be prepared having a coefficient of hydraulic conductivity that is less than 1 multiplied by 10** minus **7 cm/sec. The shear strength of...
Test Fill for a Double Liner System
A double liner system is required in hazardous waste disposal facilities to satisfy the current Resource Conservation and Recovery Act and State of Michigan Act 64 Requirements. To meet...
Design and Performance Monitoring of Clay-Lined Landfills
The use of thick clay liners has been applied to Wisconsin landfills for over a decade. Currently, there are over 35 solid waste disposal facilities in Wisconsin which have been constructed...
Acceptance Sampling for Clay Liner Design
The assurance of the quality of constructed clay liners has been a problem for geotechnical engineers. Compliance with minimum standards is necessary to ensure the liner performance capability....
