Microfiltration/Adsorption Technology for Treatment of Industrial Wastewaters: Pilot- and Full-Scale Studies
In this work the development and testing of wastewater treatment system using coagulation, microfiltration and carbon adsorption is described. Studies were conducted first on a bench or...
Preacquisition Environmental Site Assessments: Avoiding Common Errors and Omissions
The 1986 Superfund Amendments and Reauthorization Act (SARA) established an 'innocent-purchaser' defense to environmental liability from ownership of contaminated...
Decision Framework for Assessment of Leaking UST's
A computer-based environmental planning tool, designed to help mitigate the environmental problems associated with leaking underground storage tanks (UST) is presented in this article....
Soil Water Content and Air Stripping
The efficiency of air stripping for removal of volatile hazardous contaminants from soils is influenced by the water content of the soil being decontaminated. Control of soil water may...
Validity of Electro-Osmosis for Soil Decontamination
The subject matter of this paper is electro-osmosis in fine grained soils. A simple instrument has been developed to simulate this phenomena in the laboratory. A series of experiments...
Analysis of Model Uncertainty Using Bayesian Monte Carlo
Bayesian Monte Carlo analysis combines Bayesian inference with standard Monte Carlo techniques to provide improved estimates of the uncertainty in water quality model parameters and results....
Continuous Sampling of Nonpoint Source Pollution
Sediment, nutrient, and other pollutant loads from storm water runoff in a small Texas watershed have been estimated using an initial strategy of periodic grab sampling and a revised strategy...
Longterm Response of Lakes to Acidic Deposition
The longterm response of lakes in the northeastern United States to different levels of acidic deposition was predicted by using a lumped parameter hydrologic/biogeochemical model, the...
Nonpoint Source Loads and Phosphorus Budget for Lake LBJ
Nonpoint source loadings from stormwater runoff are a major contributor of pollutant loadings in many locations. A phosphorus budget is developed for Lake Lyndon B. Johnson (LBJ). Lake...
Water Quality Assessment in a Stochastic Stream Environment
Methodologies are presented within this article to aid in the quantification of the uncertainty in the management of stream water quality. Specifically, means are developed for: (1) establishing...
Anaerobic Biological Reduction of Selenate
When soils with high concentrations of naturally-occuring selenium are irrigated and drained, selenium is leached from the soil and appears in the drainage water. Selenium has caused death...
Disinfection of Wastewater Effluents with Electron Radiation
A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons...
Evaluation and Selection of RBC Models for Design of Domestic Wastewater Facilities
This study evaluated three existing models commonly used for the design of Rotating Biological Contactors (RBC). Operating data from six RBC Treatment Plants located in eastern Massachusetts...
Composting Works for Small Wastewater Treatment Plants
The City of Cooper City, Florida, faced with the undesirable position of relying on outside contractors for sludge disposal needs, undertook the task of developing a self-sufficient sludge...
Experimental Study of Windrow Composting of Sludge
An experimental field study of the windrow composition of sludge at the City of Dallas, Texas, Southside Waste Water Treatment Plant was conducted to provide data for possible design of...
Design of Solidified/Stabilized Sludge Landfills
Rehabilitation of highly moist, compressible, and heavy metal-containing wastewater treatment sludges for final disposal in a landfill setting requires consideration of several factors....
Quantitative Dye-Tracing of Karst Ground-Water Flow
Analysis of the results of repeat quantitative dye traces between a sinkhole and a spring used for public water supply were used to describe predictive relations between discharge, mean...
NAPL and Contaminant Transport in the Soil Matrix
A one-dimensional multiphase mass transport model for the migration of a Non-Aqueous Phase Liquid (NAPL) containing sparingly water soluble organics in the unsaturated soil zone is described....
Sediment Processes and the Houston Ship Channel
A year-long field and laboratory study of sediment oxygen demand was conducted on the Houston Ship Channel. The primary objective of the work was to better understand the processes controlling...
The Distribution of PCB Contaminated Sediment in the Kalamazoo River Valley, Michigan
Heightened environmental awareness beginning in the 1970s focused upon lowering contaminant levels in the Kalamazoo River system through the improvement of water quality. The Michigan...
