Rail Transit Construction Readiness: The Evolving MARTA Organization
A rail transit project is a complex undertaking involving thousands of people, expending millions of dollars and ultimately taking years to accomplish. The Metropolitan Atlanta Rapid Transit...
Managing Quality into the Workplace
In February, 1983, the author's organization began a process designed to enhance attitudes about quality in every individual member of the organization. The process requires...
Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...
Municipal Refuse: Is Burning Best?
Communities are increasingly worried about polluting groundwater, and it is increasingly difficult to get permits to start new landfills. For these reasons, there is a trend back to municipal...
Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...
Construction QA/QC Systems that Work
Case Studies
Four case studies discuss the issue of responsibility for quality assurance and quality control by describing actual situations where quality work is being done in the field. The case...
Organization and Management of Public Transport Projects
Transit development projects are undertaken to help satisfy escalating transportation needs in modern cities. The projects address an array of technical, social, and environmental considerations....
Two Dimensional Numerical Simulation of Subsurface Contamination by Organic Compounds - A Multiple Approach
In recent years, much attention has been focused on the migration of the soluble portion of an organic contaminant in groundwater systems. Little work, however, has been directed towards...
Development of a State Information Clearinghouse
The University of Virginia is conducting a study on the feasibility of establishing the Virginia Water Resources Information System (VWRIS). Objectives of the study are: 1) Documenting...
Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
Integrated air samples were obtained at seven small and six large service stations and two dealerships. These establishments were sampled during cold and warm weather operations for eight...
Predicting Areas of Groundwater Contamination
Logistic regression has been used to estimate the probability that a metropolitan area will contain one or more water supply sites with contamination by one or more of six frequently occurring...
Enhanced Mobility of Polynuclear Aromatic Compounds in Soil Systems
The objective of this study was to determine adsorption isotherms for polynuclear aromatic (PNA) compounds in methanol and a mixture of 50 percent methanol 50 percent water. The adsorption...
A Modified RBC Design: Performance Evaluation
An RBC (rotating biological contactor) system was designed using Pall rings type 40, and tested under high organic surface conditions. Influent soluble BOD averaged at 55 mg/l, equivalent...
Treatment Plant Comparisons in Removing Molecular Weight Fractions of THM Precursors
This paper describes the performance of several types of water treatment plants in removing various molecular weight fractions of natural occurring aquatic organic matter, some of which...
A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...
Evaluation of Risks Associated with Dioxin Emissions From a Resource Recovery Facility
Dioxin emissions from resource recovery facilities are a current concern to the application of this technology in the disposal of municipal refuse. A quantitative risk assessment performed...
Environmental Auditing?TVA's Experience
TVA has conducted 70 audits of various TVA operations including construction projects and power plants since 1981. In general, TVA's experience with environmental audits has...
The Balancing Act of Preparing Coastal Management Plans
There are some basic principles that should be recognised by those persons involved in preparing coastal management plans. Within the context of coastal management in South Australia,...
The Role of Nonprofits in Coastal Conservation
The California State Coastal Conservancy's Nonprofit Organization Assistance Program is a unique vehicle through which private land trusts and other nonprofits have become...
National Repositories for Tissue From Fish
A major barrier to providing an invaluable tool to the environmental sciences is the lack of any defined regional or national repository for tissues and data from fish and invertebrates...
