Fire on the Water
Incineration is a promising hazardous waste disposal technique. However, nobody wants an incinerator constructed near him, so waste handlers are considering burning hazardous wastes at...
Treatment in Your Own Backyard
Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the...
Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
Explosion Hazards to Urban Structures
Manufacture, storage and transportation of chemicals capable of exploding at energy levels comparable to TNT has increased in recent years. Land areas adjoining such facilities and transportation...
Seismic Restraint of Hazardous Process Piping
The lack of appropriate guidelines for the design and installation of hazardous process piping in industrial facilities has created a potentially dangerous situation. Process piping carrying...
Expert Systems in Civil Engineering
The importance of expert systems, also referred to as knowledge based expert systems, has been growing in all areas of civil engineering practice. The papers in this book were presented...
Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...
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...
Testing of Permeable Materials for Retaining Contaminants in Subsurface Leachates
The use of a permeable, retentive treatment system could remove both organic and inorganic contaminants while still allowing flow. A testing procedure for determining the amounts of priority...
Permeability of Grouts Subjected to Chemicals
This paper presents the more recent results of a testing program which evaluated the long-term resistance to percolation of grouted soils, using acrylate, urethane and cement-bentonite...
A Field Study of Water Movement Through Clay Liners
A monitoring system has been designed for the field verification of a numerical model of water movement through the cover clay liner of hazardous waste landfills. The most unique aspect...
Design of Final Covers for Landfills
Final covers or caps are incorporated into a completed landfill to limit the amount of moisture percolation through waste materials. A properly designed final cover system provides the...
Integration of EPA Guidelines Air Quality Models with Human Exposure/Risk Estimation Procedures
Techniques, based on dispersion models which are currently available, for performing population and maximum individual exposure and risk assessments due to ambient air emissions are described....
Unit Operations Approach in Exposure/Release Evaluation for New Chemicals
The unit operations approach may also be applied to the estimation of potential exposure and release of toxic materials from the manufacture and/or processing of new chemicals. By characterizing...
Comparison of Two Audits for Electric Utilities
Two case studies on environmental audits were examined to illustrate the differences between the comprehensive audit and a focused audit. The differences in audit team composition, technical...
Incinerating Dioxin Contaminated Waste at the USEPA Combustion Research Facility
The objective of the tests reported herein was to evaluate the incinerability of the toluene stillbottoms by determining whether 99. 9999% DRE could be achieved. All tests were performed...
Trace Toxic Metals Emissions from Hazardous Waste Incinerators
A physical model is proposed in order to explain the vaporization of metals during metallic waste incineration and is based on work performed to investigate inorganic emissions from coal...
Biological Removal of Low Levels of Chlordane
This study investigated the removal of chlordane from a synthetic hazardous waste landfill leachate with chlordane as the only hazardous material. The chlordane concentrations investigated...
Effects of Organic Compounds on the Adsorption and Desorption of Metals in Soils
This study evaluated the adsorption and release rates of toxic metals in a soil system also impacted with organic compounds. The soil type studied is common to hazardous waste sites throughout...
