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....
Influential Factors in Soil Liner Construction for Waste Disposal Facilities
Those factors most influential in the construction of a soil liner to meet a permeability performance standard of 1 multiplied by 10-7 centimeters per second (cm/sec) are identified and...
Automated Permit Review for Hazardous Waste Surface Impoundments
The United States Environmental Protection Agency has proposed to develop automated permit review for RCRA hazardous waste surface impoundment facilities. The review automation will consist...
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...
Hydrogeologic Investigations at a Superfund Site in Wisconsin
An estimated 10,000 drums of volatile organic wastes from a nearby manufacturing plant were dumped at a landfill site in southern Wisconsin. Chemicals released from these drums have contaminated...
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...
Shallow Ocean Disposal of Contaminated Dredge Material
The contaminated dredged materials from harbors and waterways along heavily populated coastal areas such as Connecticut must often be disposed at shallow ocean sites. To isolate the contaminants...
Hydrocarbon Refining Waste Stabilization for Landfills
Mobile pollutants are generated in a landfill as a function of the waste properties and the response of the deposit to the in-situ stress, climate and biochemical conditions. Release of...
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...
Embankment Over Fly Ash Pond at Portsmouth Power Station
The fly ash and bottom ash sediments from the Portsmouth Power Station in Portsmouth, Virginia were being sluiced into a 39 acre diked ash pond near the plant. The plant was about to convert...
Thickened Slurry Disposal Method for Process Tailings
Common practice in the disposal of process tailings consists of impounding the wastes as thin slurries or suspensions in diked containment areas. Such a procedure poses problems relating...
Water Treatment Plant Sludge as Landfill Liner
Chemical sludge is produced in large quantities during the water treatment processes. The present regulations pertaining to the disposal of solid wastes impose many constraints on any...
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...
Stabilization of FGC Wastes
Presently, flue gas cleaning (FGC) wastes (scrubber sludges and flyash) are produced in large quantities, with future production likely to increase as utilities install additional stack...
Little Bubbles, Big Payoff
Fine poor diffusers often boost the energy-efficiency of aeration in sewage plants by 25-50%. This is important because the combined energy bill of all U.S. municipal sewage plants is...
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...
Risk Assessment and Public Policy
A governmental official charged with making solid waste policy should be careful not to allow the public policy issue to be defined as the determination of the acceptable level of risk...
