Analysis of Transport Processes on Ocean Disposal Mound
Disposal site 'F', an ocean disposal site for dredged sediments from Coos Bay, Oregon was designed to be a dispersive site. The site has not demonstrated high...
The Challenge of Meeting New Effluent Guidelines
Meeting new effluent guidelines is presenting a challenge to the environmental engineer. In most cases, existing plants must be retrofitted which will involve options of source treatment,...
PITTLEACH: A Numerical Model of Landfill Stabilization
This paper addresses the theoretical development, use and application of PITTLEACH, a computer program conceived to simulate the processes of landfill stabilization. Since the physical,...
Implementation of Vertical Landfill Expansion
Montgomery County, Maryland, proposed to implement a vertical expansion or 'piggyback' design for the County's municipal solid waste landfill. The...
Optimization Study of a Leachate Treatment System
A treatability study was conducted to evaluate the need for a metal precipitation and an ammonia stripping process in a leachate treatment system and to evaluate the biological nitrification...
An Integrated Study of Air Toxics Emissions from an MSW Landfill
An integrated approach was used for a study of air toxics emissions at a municipal solid waste (MSW) landfill (LF) consisting of field sampling, emission estimation, atmospheric dispersion...
Chemical Composition, Physical Properties and Off-Site Migration of Municipal Landfill Gas
A sampling program of headspace gas from four monitoring wells and of off-site migration at three property line sites was conducted as part of a remedial design of a municipal landfill....
Integrated Waste Management at the Weldon Spring, Missouri Site Remedial Action Project
The diversity of contaminants and contaminated media at the Weldon Spring, Missouri CERCLA site, located about 30 miles west of St. Louis, Missouri, necessitates the formulation of integrated...
Land Disposal Restrictions and Mixed Waste Management
The Land Disposal Restrictions, imposed by Congress in 1984 and implemented by the Environmental Protection Agency, impose constraints on the management of mixed waste. Except in very...
Mixed Waste Disposal at the Texas Low-Level Waste Disposal Facility

Along the Road to K
Allegations of threats from toxic and hazardous wastes advanced on political and emotional planes threaten, themselves, to overshadow the facts that should dominate ultimate technical...
Toxicity Bioassay Using Nitrifying Bacteria
Monitoring water quality by the use of toxicity bioassay was studied with respect to the interrelationship between nitrifying activities, ammonium and inorganic compounds. Differential...
Evaluation of Waste Fly Ash Pretreatment Process
A batch acid-leaching pretreatment process was investigated for its potential to reduce toxicity and leachability of a municipal waste combustor fly ash prior to land disposal. Elemental...
