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...
The Swedish Dioxin Moratorium
Municipal waste constitutes an energy resource but also an environmental problem. In Sweden emissions of dioxines from waste-to-energy plants have triggered a major debate on environmental...
The National Incinerator Testing & Evaluation Program
Environment Canada, under the National Incinerator Testing & Evaluation Program (NITEP), is addressing emissions from municipal energy-from-waste combustion systems. The main thrust...
The Dioxin Situation in West Germany
The public discussion in Germany of the 'dioxin problem' has recently become more rational than it was three years ago. Emotions and hard facts are in a balance...
Wastewater Technology Innovation for the Year 2000
The present state of wastewater technology research is on a decline because of shrinking funds. A national effort by professionals in all sectors of the wastewater establishment is encouraged...
An Investigation of the Alcatraz Disposal Site
The Alcatraz dredged material disposal site in San Francisco Bay is a dispersive site that is not intended to accumulate disposed sediment. However, the recent discovery of shoaling at...
Dispersal of Dredged Material Disposal Plumes
An empirical model describes dispersal of dredged material disposal plumes in an urban estuary, Central Long Island Sound, during spring of 1983. The model uses in situ current meter data...
Nuclide Migration from Areal Sources Into a Fracture
The authors show analytic solutions to the problem of hydrogeologic transport of radionuclides released from finite areal sources into a planar fracture. The authors illustrate the solutions...
A Large-Scale Groundwater Transport and Dispersion Test: The First 1000 Days
TVA is conducting a large-scale field experiment to quantify the groundwater transport and dispersion of leachates from solid disposal facilities. This project is an integral part of the...
Contaminant Transport from an Array of Sources
The authors show analytic solutions to the problem of contaminant dispersion from an array of point sources in a waste disposal site. These solutions are for waste sources in a fluid-saturated...
The Lubbock, Texas, Land Treatment System
The land treatment system at Lubbock, Texas provides an excellent model for studying the response of a system to growth. It also provides insights and justification for current criteria...
Utilization of Geographic Information Systems Technology in the Assessment of Regional Ground-Water Quality
The U. S. Geological Survey (USGS) in cooperation with the U. S. Environmental Protection Agency Office of Pesticide Programs and several State agencies in Oregon has prepared a digital...
Selenium Removal?Can We Afford It?
The process of biologically removing the element selenium from agricultural drainage water is discussed and an economic evaluation of the process is presented. If by-products can be recovered,...
Agricultural Drainage Water?How Should It be Regulated?
This paper discusses the existing framework of California liquid waste disposal law, the obstacles presented by these and other laws pertaining to agricultural drainage water disposal...
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...
