Making a Map of Public Health Hazards
Accurately deducing the long-term exposure of community members to health hazards has always been a challenge for engineers. In 1993, the town of Somers, Conn., discovered a residential...

Critical Issues in the Monitoring and Control of Toxic Air Contaminants at POTWs
Todays challenge at Publicly Owned Treatment Works (POTWs) is to assess and reduce the environmental risk posed by toxic air contaminants (TACs). This paper attempts to identify the critical...
A Simplified Process Audit to Design an Affordable Pollution Prevention and Waste Management Plan -
This paper presents a simplified approach to the general audit procedure that is applicable to the Small and Medium Enterprise (SME). The process leads to the identification of major sources...
Pilot Testing of a Zero-Discharge Treatment Process
As environmental regulations become more stringent, pulp and paper mills are investigating alternatives to conventional biological treatment and discharge of effluents into receiving waters....
Permeability of Clay Liners with Contaminants
Clays are increasingly used as liners for waste disposal facilities. Chemical compatibility studies with hydraulic conductivity tests must be performed to determine the effect of the waste...
Design and Implementation of a Multi-Faceted Site Remediation
This technical paper presents a case history of the design, construction, and start-up of a multi-faceted site remediation system. The case history includes a description of the site background,...
Secondary Containment Design Practices
Over the past several decades the design approach to containment of spills has not been consistent resulting in release of hazardous substances into the environment. The increased discovery...
Comparative Simulation of Oil Weathering
Oil spills in the aquatic environment, an unfortunately more and more common occurrence, cause contamination effects which negatively impact water quality, health of ecosystems and water...
Study of Biological Reactors for Control of Odor, VOC and Toxic Emissions from Wastewater Treatment Plants
An experiment was performed to assess the use of biological reactors to treat off-gases from publicly owned treatment works (POTWs) containing low concentrations of hydrogen sulfide (H2S)...
Rehabilitating Arctic Tundra in Alaska
During the past 25 years, there has been significant progress in tundra rehabilitation. Initially, agronomic practices requiring large quantities of grass seed and fertilizer were believed...
Oil Spills: Prevention, Prediction, and Preparation
This paper summarizes some of the state and federal rules, assessment techniques, and response procedures being used by marine terminals along coastal California to prevent, predict, and...
Production of Nitrous Oxide Gas under Sequencing Batch Reactor System

Fluidized Bed Denitrification of Secondary Effluent during Wastewater Reclamation in Southern California
A pilot scale fluidized bed denitrification bioreactor was operated for a period of three years as one unit process in a series designed to repurify secondary effluent for subsequent indirect...
Anaerobic Biodegradation of High Energetics in Digestion Sewage Sludge
The digested sewage sludge culture is highly effective for denitrification and the subsequent degradation of energetics contained nitrites. Two energetics, ADN (ammonium dinitramide) and...
Significance of Geologic Features on the Contaminant Migration from Landfill Sites
Contaminants (leachate) migration pathways in various media at hazardous waste and landfill sites are primarily defined by the local geologic features at such sites, namely:stratigraphy,...
