Conversion of a Reservoir Into a Landfill Site
The Writer is acting as a geotechnical consultant during the conversion of a disused water reservoir into a landfill site for domestic and industrial refuse. The site developer had no...
Bentonite Matting in Composite Lining Systems
The 1984 Hazardous and Solid Waste Amendments to RCRA mandated that double lining systems utilizing synthetic membrane liners be required for hazardous waste landfills. Recognizing the...
Environmental Monitoring and Observations Before and During Excavation of a Landfill in Owatonna, Minnesota
A Minnesota landfill inactive since 1962 was excavated in 1985 to prepare the site for construction of a new waste water treatment plant. The excavation refuse was disposed of in nearby...
EPA Municipal Waste Combustion Activities
In many areas of the country, existing municipal waste landfills are reaching capacity. Land for new landfills or expansions is scarce and expensive, and municipalities would generally...
A Burning Wasteland Reclaimed
Until recently the PJP Landfill exemplified what can happen when uncontrolled and illegal dumping goes on for many years. Now it is an example of what innovation and imagination can do...
Geosynthetics Unearthing New Applications
Geosynthetics are now a $700 million industry. Called geomembranes, geotextiles, geogrids and geocomposites, geosynthetics complement or replace geotechnical designs. Five case studies...
Permafrost: A Suitable Landfill Containment Barrier
Ice-rich permafrost is a suitable medium for the containment of wastes. The combination of frigid dry Arctic climate and the impermeability of ice-cemented permanently frozen ground can...
Overcoming Opposition
During a zone change hearing in connection with site selection for a new landfill near Coeur d'Alene, Idaho, some honest communication overcame opposition by the residents....
Emission and Control of Volatile Organics in Hazardous Waste Landfills
Landfill simulation and modeling can provide a useful tool in the management of hazardous wastes to estimate the vapor phase emissions of pollutants so that a realistic assessment can...
A Field Study of Water Movement Through Clay Liners
A monitoring system has been designed for the field verification of a numerical model of water movement through the cover clay liner of hazardous waste landfills. The most unique aspect...
Design of Final Covers for Landfills
Final covers or caps are incorporated into a completed landfill to limit the amount of moisture percolation through waste materials. A properly designed final cover system provides the...
Effects of Industrial-Municipal Co-Disposal
A study was conducted to evaluate the physical, microbiological, and chemical conditions of nineteen experimental landfills after the completion of a ten-year long municipal refuse/industrial...
Evaluation of Landfill Leachate Recirculation
The effectiveness of leachate recycle as a leachate management technique has been evaluated at a landfill in central Pennsylvania where recirculation has been practiced for seven years....
Hydrogeologic Investigation of the Chillicothe, Ohio Landfill
A hydrogeologic investigation of a municipal waste landfill determined that the local surface and ground water are being polluted. Water quality monitoring and aerial photography were...
Design Study of an Above-Grade Landfill
A design study on the feasibility of utilizing an above-grade landfill for the disposal of hazardous wastes has been completed. This design study comprised three phases of work - a literature...
Lessons Learned Implementing the Minimum Technology Guidance for Landfills
The 'Minimum Technology Guidance on Double Liner Systems for Landfills and Surface Impoundments' issued by the Environmental Protection Agency (EPA) in May 1985...
Analysis of Unsaturated Flow Beneath a Landfill
Using the linearized theory of flow in unsaturated porous media, a mathematical model was developed to study the distribution and extent of unsaturated flow from a source of infiltration...
Allowable Metal Contaminant Levels in Landfilled Sludge
Disposal of municipal sludges in dedicated sanitary landfills can be environmentally acceptable. Contaminants within the sludge present the potential for public health risks but these...
Codisposal of Low-Level Radioactive Cobalt Within Sanitary Landfills
The potential of resolubilization of radioactive cobalt from cobalt sulfide by humic substances present in landfill leachate was investigated. Equilibrium and kinetic studies on the potential...
Variable Leachate Treatment System: A Cast Study
This paper explores the experience of the authors in collecting data and designing leachate collection and treatment facilities at municipal sanitary landfills over the last several years....
