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...
Arranged Delivery Schedules
The method of delivery of irrigation water to farmers from irrigation districts vary considerably from one project to another. Rotation delivery systems usually place too many restrictions...
Implementation and Management of a High Technology Irrigation System
Eastern Oregon Farming Company (EOFC) irrigates 12,000 acres using a fully pressurized irrigation system. In 1981, the system was operated with minimal flow and pressure measurements and...
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...
Subsurface Drainage for Erosion Reduction on Croplands of Northwestern Oregon
Subsurface drains installed as a relief system on sloping cropland reduced surface runoff and soil loss from silty soils with underlying slowly permeable layers in northwestern Oregon....
Sprinkler Erosion Model
The Soil Conservation Service has developed a model to evaluate the effect of various sprinkler irrigation systems with associated agronomic practices. Many researchers have dealt with...
Considerations for Sizing Water Delivery Systems
The purpose of a water delivery system is to deliver irrigation water to a farm and its design should be based on meeting the requirements of farm water use. The rate, duration and frequency...
Farmer Adoption of Irrigation Automation
Farmer acceptance of irrigation automation for water conservation in the eleven Western states is limited. About 29,000 acres, or 0. 1 percent, of the 25 million acres irrigated in these...
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...
