Evaluation of the City of Venice Urban Reuse Program
The City of Venice is located on the Gulf of Mexico in west central Florida. With a mild sub-tropical climate and coastal location, the small community is a prime target for rapid development....
EPA Guidelines for Water Reuse
The U.S. Environmental Protection Agency and the U.S. Agency for International Development are cosponsoring preparation of water reuse guidelines. The guidelines are being developed to...
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...
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...
Inside the Manhole: New Design on a Leaky Link
Wastewater collection systems represent a major investment for every community, not only in capital dollars, but also in the well-being of community members. Though sanitary sewer manholes...
Navy Targets Effective Infiltration/Inflow Elimination
The Naval Facilities Engineering Command (NAVFAC), Chesapeake Division, retained the services of RJN Environmental Associates, Inc. to perform a Sanitary Sewer Evaluation Survey (SSES)....
Combined Nitrogen and Phosphorus Removal in a Cyclic Activated Sludge System Without Anoxic Mixing Sequences
A simplified methodology for combined phosphorus and nitrogen removal through reactor configuration, cyclic sequencing and the control of aeration intensity in variable volume activated...
Environmentally Sustainable Development: A Concept in Action
Environmentally sustainable development denotes a balanced approach with appropriate consideration for environmental protection. The successes achieved in the development of five diverse...
Propositions for Packed Bed Adsorption Reactor Design
This paper states ten propositions which describe the behavior of 'wave fronts', i.e., adsorbate concentration versus distance profiles at given elapsed times,...
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...
Toxicity Bio-Assays, 5-Day BOD and
This article revisits some of the basic definitions of toxicity bioassays and 5-day BOD and questions the the precision of these measuements and the long duration of these tests....
Screening Level Modeling in Support of an Estuarine Toxics Management Program
Mathematical models will be used in the future to determine maximum allowable pollutant loading rates for several toxics to the South San Francisco Bay Estuary. This project consisted...
Evaluation of
This paper examines the potential application of in-situ bio-dentrification as well as pertinent physical and biochemical factors that control the process to reduce nitrate in groundwater...
Integrated Management of Sugarcane Mill Wastewater for Bioenergy Production and Drip Irrigation
Based on the previous work of wastewater characterization and relevant literature review, a combined anaerobic (UASB) and aerobic (EAFB) treatment of supernatant of settled sugarcane mill...
Reuse of an Industrial Wastewater at Saturn
The cooling tower at General Motor's Saturn Plant in Spring Hill, Tennessee will produce blowdown wastewater at rates as high as 500,000 gallons (1893 m3/day)....
Nonpotable Reuse: Development of Water Quality Criteria for Shower Water Recycle
Shower wastewaters at a military installation have been characterized in terms of physical, chemical and microbiological parameters. Two treatment technologies, microfiltration and coagulation...
Salinity Problems Associated with Reuse Water Irrigation on Southwestern Golf Courses
One of the most severe of the potential reuse water quality problems is salinity. While many water supplies in the southwest have relatively high total dissolved solids (TDS) concentrations,...
Adsorption of Lindane onto Whole Soil and Soil Organic Fractions
The work presented here investigated interactions of the subject pesticide with whole soil and select soil organic fractions and evaluated the commonly applied assumptions that adsorption...
Development of a Sorbent for Removal of Nonionic Pollutants from Water
Sorption of anionic surfactants onto mineral oxides and, and the subsequent partitioning of non-ionic organic substance into the organic phase of these synthetic sorbents was studied....
Behavior of Three Organic Chemicals Passing Through Columns Packed with Sand and Silt in the Presence of Landfill Leachate
This study examines the effect of leachate on the migration of three common industrial chemicals in unsaturated flow under two sets of soil conditions: sand and sand with a layer of silt....
