Characteristics of Wastes, Leachate, and Gas at Landfills Operated in Arid Climate
(American Society of Civil Engineers, 2005)A total of 14 liquid waste samples were collected from different sources at all five landfill sites and from disposal containers in Kuwait representing a model of arid countries. Al-Sulaybiya landfill (operating) and ... -
Removal of Phenol by Industrial Solid Waste
(American Society of Civil Engineers, 2005)Batch experiments have been carried out to study phenol removal from a synthetic phenol solution by adsorption onto blast furnace flue dust from a steel plant and slag generated in chrome alloy plants. Removal efficiencies ... -
Evaluation of Treatment Systems for the Removal of Arsenic from Groundwater
(American Society of Civil Engineers, 2005)High concentrations of iron and arsenic are common in Saskatchewan groundwater. Their cost effective removal from groundwater is a challenge for small communities. Four small treatment systems were tested for iron and ... -
Removal of Oil from Water by Bentonite Organoclay
(American Society of Civil Engineers, 2005)Powdered bentonite organoclay was used to remove oil from water in this study. The oil-in-water emulsions used were standard mineral oil (SMO), Kutwell45 (KUT45), and Valcool (VAL) (two cutting oils), refinery effluent ... -
Dynamic Model for Calculating Infiltration of Rain Water through an Unsaturated Zone, and Its Application to Environmental Protection Agency’s PRESTO Model
(American Society of Civil Engineers, 2005)The EPA’s multimedia environmental pathway model, Prediction of Radiological Effects due to Shallow Trench Operation (PRESTO), has been applied extensively to scenarios involving both the remediation of soil contaminated ... -
Biosorption of Chromium (VI) by Nonliving <i>Fusarium</i> sp. Isolated from Soil
(American Society of Civil Engineers, 2005)Batch biosorption of chromium(VI) from an aqueous solution was studied using dry biomass of -
SITE Demonstration of Minergy Glass Furnace Treatment of PCBs, PCDDs/Fs, and Metals in River Sediment
(American Society of Civil Engineers, 2005)The U.S. Environmental Protection Agency Superfund Innovative Technology Evaluation (SITE) program selected the Glass Furnace Technology (GFT) treatment process for evaluation. The GFT was developed by Minergy Corporation ... -
Modeling of a Groundwater Circulation Well Removal Action Alternative
(American Society of Civil Engineers, 2005)This paper presents the basis for using groundwater circulation wells (GCWs) for removal actions focused on contaminated domestic water supplies. A properly placed GCW could be used to pretreat water before it enters a ... -
Biodegradability of 2,4-Dichlorophenol under Different Redox Conditions
(American Society of Civil Engineers, 2005)Chlorophenols are generated from a number of industrial producing processes and are extensively used as insecticides, herbicides, and fungicides. Their discharge into the environment is of great concern due to their toxicity. ... -
Waste Isolation Pilot Plant as a Case Study for the Deployment of a National Repository Program
(American Society of Civil Engineers, 2005)The permanent disposal of nuclear wastes, such as transuranic (TRU) wastes, high-level wastes, and spent nuclear fuel, that require isolation over thousands of years (due to the presence of long-lived radionuclides and ... -
Ensuring Future Skills: Education and Training in Underground Waste Disposal
(American Society of Civil Engineers, 2005)Progress has been slow in solving the radioactive waste disposal problem, with wide swings in the resources deployed in national programs over the last -
Long-Term Radioactive Waste Management in the United Kingdom—Nirex Perspective
(American Society of Civil Engineers, 2005)This paper sets out the background to and history of radioactive waste management in the United Kingdom (UK). It describes the lessons learned from past attempts to implement a long-term management solution, and outlines ... -
Hazards of Buried Radioactive Wastes from Electricity Generation
(American Society of Civil Engineers, 2005)We consider the risk of high level radioactive waste from nuclear power plants, once buried in the ground, being released by ground water intrusion and eventually being ingested by a human to cause cancer. A probabilistic ... -
Geological Disposal: Global Status and Key Issues
(American Society of Civil Engineers, 2005)The aim of this article is to give an objective appraisal of the development of the concept of geological disposal of radioactive wastes and of its status today. It addresses the key issues associated with geological ... -
Activities of the Advisory Committee on Nuclear Waste and Perspectives on Selected Technical Issues
(American Society of Civil Engineers, 2005)The Advisory Committee on Nuclear Waste advises the Nuclear Regulatory Commission on public health and safety issues in relation to nuclear materials and nuclear wastes. The advice includes safety and environmental protection ... -
The Management of Radioactive Waste in the European Union—Opinions, Situation and Proposal for Changes
(American Society of Civil Engineers, 2005)Radioactive waste is seen by many as the major issue for nuclear energy in the European Union (EU). Public opinion surveys conducted by the European Commission show that while they know little about radioactive waste, the ... -
Errors Involved in the Estimation of Leachate Pollution Index
(American Society of Civil Engineers, 2005)An environmental index known as the leachate pollution index (LPI) to quantify and compare the leachate contamination potential of municipal landfills in a given geographical area was developed and reported elsewhere. The ... -
Consensus Seeking Versus Truth Seeking
(American Society of Civil Engineers, 2005)Postmodernists have long argued that giving an egalitarian voice to all citizens by seeking consensus decisions with cooperation improves social welfare more effectively than the competition traditionally used with common ... -
Modeling Phytoremediation of Soils
(American Society of Civil Engineers, 2004)A numerical model that determines the uptake of cadmium by plants grown to remediate contaminated soils is developed in this study. The numerical model is first applied to the problem of copper uptake from contaminated ... -
