Modeling Dilution of Wastewater Outfalls in a Tidal Estuary
Field studies and modeling have been conducted to assess initial dilution of wastewater outfalls in Puget Sound, a fjord-like estuary in the State of Washington. Recent numerical dilution...
The Benefit of Utilizing Case Specific Modelling and Data to Determine Effluent Limitations
This abstract refers to the results of a normal conservative approach to a more realistic, substantiated approach to determining effluent limitations. The new approach was used to establish...
Application of an Ecosystem/Water Quality Model as a Tool for Managing Estuarine Water Quality
A laterally averaged two-dimensional computer model was developed to simulate the hydrodynamics, transport, and ecosystem dynamics of Budd Inlet, a small partially mixed estuary located...
Athens Siphon and Outfall
More than 130 million gallons of untreated domestic and industrial wastewater are discharged each day into the sea near Athens. To mitigate this situation, the government of Greece is...
Erosion of the Slopes of Gold Tailings Dams
A study has been made of rates of erosion from the slopes of gold-residue dams in the South African Highveld region. Data is available for two years at this time and conclusions must therefore...
Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...
Reclamation of Athabasca Oil Sand Sludge
The bulk of oil sand tailings (80 to 90%) consists of quartz sand, which is defined to be everything coarser than 44 microns. The other 10 to 20%, termed 'sludge',...
Design and Performance Monitoring of Clay-Lined Landfills
The use of thick clay liners has been applied to Wisconsin landfills for over a decade. Currently, there are over 35 solid waste disposal facilities in Wisconsin which have been constructed...
The Effects of Brine Contamination on the Properties of Fine Grained Soils
Laboratory tests have been performed to investigate the effects of brine contamination on grain size distribution, relative density, liquid and plastic limits, hydraulic conductivity,...
Thickened Slurry Disposal Method for Process Tailings
Common practice in the disposal of process tailings consists of impounding the wastes as thin slurries or suspensions in diked containment areas. Such a procedure poses problems relating...
Water Treatment Plant Sludge as Landfill Liner
Chemical sludge is produced in large quantities during the water treatment processes. The present regulations pertaining to the disposal of solid wastes impose many constraints on any...
Stabilization of FGC Wastes
Presently, flue gas cleaning (FGC) wastes (scrubber sludges and flyash) are produced in large quantities, with future production likely to increase as utilities install additional stack...
Environmental Monitoring and Observations Before and During Excavation of a Landfill in Owatonna, Minnesota
A Minnesota landfill inactive since 1962 was excavated in 1985 to prepare the site for construction of a new waste water treatment plant. The excavation refuse was disposed of in nearby...
Little Bubbles, Big Payoff
Fine poor diffusers often boost the energy-efficiency of aeration in sewage plants by 25-50%. This is important because the combined energy bill of all U.S. municipal sewage plants is...
Wastewater Technology Innovation for the Year 2000
The present state of wastewater technology research is on a decline because of shrinking funds. A national effort by professionals in all sectors of the wastewater establishment is encouraged...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
A Large-Scale Groundwater Transport and Dispersion Test: The First 1000 Days
TVA is conducting a large-scale field experiment to quantify the groundwater transport and dispersion of leachates from solid disposal facilities. This project is an integral part of the...
U.S. Bureau of Reclamation: How Irrigation Projects are Sized
The objective of this study was to review the methods presently used by the United States Department of Interior, Bureau of Reclamation (Bureau) to estimate the water requirements for...
Reclaiming Wastewater in Phoenix, Arizona
This paper examines the role of wastewater effluent reuse in the future water resource management of the City of Phoenix. The paper seeks to explain why a proposal to renovate effluent...
The Reclaimed Water Delivery System and Reuse Program for Tucson, Arizona
The City of Tucson has implemented a reclaimed water reuse program in a community-wide effort to preserve high quality groundwater for potable and other priority uses. Presently, the system...
