Introduction
This chapter serves as an introduction to the monograph, including its purpose, scope, and organization....
Wireless System
The technology of using radio frequencies to communicate is not new. Ham radio and walkie talkies were the first form of radio communication used by the public; then the Citizen Band (CB)...
Ground-Water Treatments Gain Ground
Ground water is the main source of the nation's public water supplies and is also used extensively for agricultural and industrial purposes. Yet our reserves are constantly...
Leachate Chemistry: Its Implications for Clogging
The clogging of leachate collection systems is controlled by interrelated mi and chemical phenomena. Mesocosms containing landfill materials and simulating leachate collection were infiltrated...
Potential Microbial Impacts on Groundwater Quality
Over the last decade there has been significant progress in the understanding of sub-surface microbiology. The ubiquity of microorganisms within groundwaters forms a major part of these...
VOC Inventory at New York City Wastewater Treatment Plants
Although the New York State Clean Air Act Amendments of 1990 (CAAA) implementation plan is not yet in place, the Citys Department of Environmental Protection (DEP) is taking a proactive...
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....
Drainage Ponds and Demonstration Wetlands
In California's southern San Joaquin Valley, subsurface irrigation drainage pumped into shallow evaporation ponds often contains elevated concentrations of selenium. The selenium...
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)...
Risk Analysis of Drinking Water Treatment and Supply Facilities Handling Highly Hazardous Chemicals
Due to increasing public concern of risks from handling highly hazardous chemicals at various facilities, a number of state regulatory agencies, including the State of California, have...
Overview of Drought Response Strategies
An overview of drought response strategies in the United States is presented. The paper focuses on tactical strategies for mitigating the impacts of drought conditions. A general structure...
Vapor Phase Biofiltration for Removal of VOCs
The selection of an appropriate packing material for the biofiltration process is an important factor in the removal of contaminants from vapor phase. This study evaluates two different...
Geochemical Modeling of Lead in Vadose Zone
In recent years, researchers have used multicomponent reactive transport models to study the mobility of potentially toxic heavy metals in the subsurface. In this study, such a mathematical...
Health Risk Sensitivity to Variable and Uncertain Parameters
A methodology is presented that attempts to quantify the effects of individual variability and parameter uncertainty in a groundwater-driven health risk assessment. Two modeling approaches...
The Importance of Water Depth for Sparger Performance
As part of TVA Hydro Modernization Program, the two 59-year old Francis turbines at Norris Dam have been upgraded with new units. In conjunction with TVA's Reservoir Releases...
The Environmental Valuation Reference Inventory (EVRI) for Water Related Benefits Transfers
Managing our water resources requires knowledge not only of flows, water chemistry and aquatic life, but also of the various uses and economic values that humans place upon the water....
Recover Inorganic Solids from Obsolete Propellants
A feasible process was developed to recover inorganic solids (energetics and metallic fuel) from obsolete polyurethane-based propellants in order to solve their associated long-term disposal...
Optimization of Soil Vapor Extraction System Design
Soil vapor extraction is a cost-effective technique for the removal of volatile organic compounds (VOCs) immobilized in the unsaturated zone. The design of a soil vapor extraction system...
Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5?9), and the redox potential...
