A Case Study of Ground Water Quality Protection in California
Incidents of ground water contamination from improper disposal of industrial wastewater have been widespread throughout California. In late 1984 the State Water Resources Control Board...
Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
Emerging Environmental Clean-Up Responsibility
This paper is a summary of the structure of regulations requiring clean-up of sites when closed or sold, specifically the State of New Jersey's Environmental Cleanup Responsibility...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
Computer Control of Lift Station Operations
A unique computerized control system to supervise the operation of several lift stations has been designed by Boyle Engineering Corporation (Boyle) and constructed by the City of Orlando,...
Los Angeles Infiltration/Inflow Reduction Program
The City of Los Angeles maintains and operates two wastewater collection and treatment systems: the Hyperion System and the Terminal Island System. During the wet months of December through...
Role of Air in Improving First-Stage RBC Performance
A four-stage RBC (rotating biological contactor) treatment plant having two parallel trains is used to treat combined municipal and industrial dairy waste from a city with a population...
Fluidization of Biomas Covered Sand Particles
The expansion behavior of the fluidized bed reactor support medium is important in its design and analysis. Steady state and dynamic behavior of fluidized bed expansion were compared with...
Resource Recovery Mass-Burning Incineration
The various types of incineration systems are discussed, and the technical and economic factors to be considered in developing a resource recovery project are examined....
Quality Assessment Standards & Low-Level Nuclear Waste: How Standards Have Been Developed and Applied
The authors examine the application of organized quality assurance procedures to the nuclear industry since 1970....
Codisposal of Low-Level Radioactive Cobalt Within Sanitary Landfills
The potential of resolubilization of radioactive cobalt from cobalt sulfide by humic substances present in landfill leachate was investigated. Equilibrium and kinetic studies on the potential...
Method Development for Evaluating Radionuclide Emissions from Incineration of Low Level Radioactive Waste
The implementation of an incineration monitoring program for low level radioactive waste is a complex task, especially in the area of obtaining environmental permits. Emissions monitoring...
Water Diversion at Low-Level Waste Disposal Sites
Shallow depth to groundwater, surface drainage, and subsurface flow during storm events are major environmental concerns of low-level radioactive waste management operations in humid regions....
Electrically Fired Incinerator System for Combustible Radioactive Waste
DuPont Company and Shirco, Inc. are developing a process to incinerate plutonium-contaminated combustible waste in an electrically fired incineration system. Preliminary development was...
A Systems Approach for Wasteload Allocations
A methodology for determining an optimal periodic permit for a single discharger situation was developed which accounts for effluent variability, as well as the variability of the receiving...
The Use of Activated Carbon as a Polishing Step for Treatment of Industrial Plating Wastewaters
An activated carbon adsorption process was utilized as a polishing step following the precipitation (hydroxide or sulfide) process. Zinc and cadmium were the metals studied. Since plating...
Industrial NPDES Toxicity Goals
Biological monitoring of NPDES (National Pollution Discharge Elimination System) effluents is becoming a reality in several EPA regions. While the advantages are genuine the loopholes...
Factors Influencing Zinc Cementation of Cadmium
The research reported here examines an innovative procedure for removal of cadmium from wastewaters. This process is the cementation of cadmium by zinc metal. Cementation is highly attractive...
The Adsorption Characteristics of NI (II) Onto Bubble Surface
The removal of Ni(II) by foam fractionation is brought about by the electrostatic mechanism. From removal and zeta potential measurements, it clearly demonstrates that Ni**2** plus and...
Fixation of Chromium and Cadmium from Electroplating Waste Sludges
The authors compare the effectiveness of two fixation techniques, namely silicate-cement and lime-fly ash, for immobilizing chromium and cadmium in a waste sludge obtained from an electroplating...
