Modular Plastic Media for Shallow Bed Trickling Filter Applications
Little specific data is available for less sophisticated trickling filter systems which employ recent plastic media designs for shallow bed filters without the added cost of subsequent...
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...
Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...
Optimization of Design and Operating Parameters for Single-Media, Unstratified-Bed Filters
The potentially successful use of filters containing large grain-size single media for water filtration has prompted investigation of the parameters controlling the performance of these...
Age-Specific Cancer Risk Analysis for a Population Exposed to Contaminated Drinking Water
Recent developments in the methodology for estimating cancer risk for environmental contaminants exhibit promise for improved predictability of risk analyses based on EPA risk guidelines....
A Study of River Foaming and its Possible Causes
Foaming has been observed on uncontaminated upland streams draining watersheds having no human related development. Because water alone will not foam when agitated, the presence of these...
Design of a GAC Water Treatment System for Radon
The author describes the design of a granular activated carbon (GAC) treatment system for the removal of radon from a public water supply....
Issues in Dam Grouting
Although perhaps the largest number of individual grouting projects do not involve dams, by far the largest volume of grout used is for grouting of new or existing dams. This volume presents...
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...
The Engineering Aesthetics of Tall Buildings
The Proceedings of a session on the Aesthetics and Design of High-Rise Buildings at the ASCE Convention in Denver is included in its entirety. The session was chaired by Lynn Beedle and...
The Analysis of the Environmental Impact
Oil serves mankind. Winning such a valuable and necessary energy resource demands for stringent rules. It is not the oil which threatens the environment on earth, but the negligence of...
Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...
Oil Spill Risk Assessment for Marine Vessels
An oil spill risk assessment study should show the estimated relationship between the magnitude of an adverse environmental impact and the probability of equaling or exceeding that impact....
Report: Persian Gulf Conference, May, '84
The First International Conference on the Impact of Oil Spill in the Persian Gulf was held at the University of Tehran, Islamic Republic of Iran (I. R. I. ), from 20 May to 27 May, 1984....
Who's Minding the Beach?...The Virginia Experience
Virginia entered the realm of statewide funding for the enhancement of public beaches on July 1, 1980 with the creation of the Commission on the Conservation and Development of Public...
Contained Dredged Material for Open Ocean Disposal
An intensive series of investigations were conducted on the sediments deposited in Craney Island, a 1012 hectare contained disposal facility in the Port of Hampton Roads, VA. Geographic...
Dredge Material Evaluation Through Harbor Characterization in New England
The New England Division (NED) of the Corps has recently developed a broad based methodology for simultaneously evaluating dredging projects that are in close proximity and which would...
Radioactivity in the Ocean: Laws and Biological Effects
This paper summarizes the literature on U. S. laws and international agreements, experimental and monitoring data, and ongoing studies to provide background information for environmental...
The Maryland Dredge and Fill Permit Process Handbook
The current dredge and fill permit process in Maryland has become a complex procedure involving many agencies from each level of government. The process by which a permit is obtained for...
The Bowhead Whale and Offshore Petroleum Operations in the Arctic
Eskimos, environmentalist groups, and government agencies have stated their concerns about possible effects on the bowhead from offshore petroleum operations. These concerns fall into...
