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...
Stabilized Fly Ash for Use as Low-Permeability Barriers
Two class F fly ashes from power stations located in West Virginia were stabilized by adding various percentages (by weight) of either lime or cement. Test specimens were subjected to...
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...
Evaluation of Compacted Inert Paper Solids as a Cover Material
The following paper presents the results of a laboratory test program which focused on compacted sludges or inert paper solids (IPS) as recommended cover (cap) material over existing IPS...
The Use of Cone Penetration Testing for Evaluation of Waste Disposal Alternatives
Geotechnical information derived from cone penetration testing (CPT) has been found to give increased accuracy in the siting of waste disposal facilities and in the design of remedial...
The Typical Engineering Properties of Fly Ash
Knowledge of key physical and engineering properties of coal fly ash is needed in the planning, design, and construction of both disposal and utilization projects. While considerable data...
Evaluation of Waste Disposal Sites Using Geotox
GEOTOX is a knowledge-based expert system designed to assist in the identification and classification of waste disposal sites. Existing methodologies such as formal or qualitative risk...
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...
Dioxins and Human Health
Few environmental issues have attracted as much attention and controversy as the dioxins. Considerable expense has been incurred investigating effects in human populations and laboratory...
On-Farm Management Alternatives to Reduce Subsurface Drainage in the San Joaquin Valley, California?Constraints to Implementation
The most cost effective approach for mitigating the drainage problem is incorporating on-farm management practices that reduce percolation and seepage losses to the shallow groundwater...
An Overview of Factors Affecting Land Application of Food Processing Wastes
The food processing industry can use slow rate, rapid infiltration or overland flow systems. Slow rate systems are the most common method used for land application. The limiting design...
Garbage: Cogeneration's Third Dimension
Burning garbage or refuse derived fuels (RDF) is becoming more common in cogeneration plants being constructed in the U.S. The three-for-one concept turns one fuel into two products (steam...
Geotechnical Practice for Waste Disposal '87
This volume contains 55 papers covering many aspects of geotechnical issues associated with waste disposal. The papers represent advances during the intervening decade since the first...
Dioxin and Resource Recovery
The 1987 ASCE Dioxin and Resource Recovery Symposium was held at the New York Hilton Hotel, New York on February 10, 1987. The conference served as an opportunity to assess the issue of...
Cleaning Up Toxics
Case histories show how several different types of contamination cleanup were handled. In Attleboro, Mass., washwater, used to decontaminate equipment and tools after cyanide was removed...
Recyclying of Dust from Electric Arc Funances�An Experimental Evaluation
Each year the electric arc steelmaking industry generates approximately 650,000 tons of dusts containing valuable metallic resources such as iron, zinc, lead, and chromium. EAF dust is...
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...
Detoxifying Metal-Contaminated Solid Wastes by Induced Ion Exchange?A Theoretical Evaluation
The presence of minor amounts of insoluble heavy metal precipitates may render a large body of innocuous solids (say fly ash, soil, calcium carbonate or even biological sludge) potentially...
Initial Operations Report
In the fall of 1983, Fort Collins City placed into operation its 152. 6 hectare (377 acre) Resource Recovery Farm, which receives liquid sludges from the City's wastewater...
Agricultural Drainage Water Treatment?Are Toxic Elements Useful?
The problems pertaining to disposing of agricultural drainage water in the San Joaquin Valley are explained. Details are presented on a pilot plant which is pretreating the drainage water...
