Biological Treatment of Hazardous Wastes
Biological treatment�using nature's bacteria and fungi�sometimes costs as little as 10-20% as incineration. Wastes in any form�solid, aqueous and gaseous�can be treated biologically....
A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...
Drawing up Waterproof Curtains
Curtain wall damage has recently become the number one source of building owner complaints. Until wall systems are designed with backup water collection systems and other details, leakage...
Iowa's Experience with Various Types of Pipe in Natural Gas Service
The Utilities Division, Iowa Department of Commerce, is responsible for the rate, service, and safety regulation of utility companies in the State of Iowa. This paper will summarize a...
Boston's Water Distribution Corrosion Control Program
The Boston Water and Sewer Commission (Commission) was formed in 1977 with a mandate to maintain sound, economical, and efficient systems for water distribution and wastewater collection...
Design for Variable Frequency Drive Applications

A Summary Description of Design Criteria, Codes, Standards, and Regulatory Provisions Typically Used for the Civil and Structural Design of Nuclear Fuel Cycle Facilities
A summary of design criteria, codes, standards, and regulatory provisions applicable to the civil and structural design of the eight principal facilities of the nuclear fuel cycle are...
Determining Transit Losses for Water Deliveries by Use of Stream-Aquifer Models
Hydrologic modeling of stream-aquifer interaction commonly has been used to quantify transit losses associated with water deliveries, such as those from reservoir storage. This technique...
Conveyance Characteristics of Natural Channels in Wyoming
This paper addresses the quantification of instream or conveyance losses of water being transported within natural stream systems in Wyoming using a net total loss and incremental loss...
Characterizing Groundwater Protection Zones
A method is presented for using geoelectrical methods along with a supporting systems methodology to define aquifer and/or well head protection zones. The systems methodology utilizes...
Measurement Systems in the Hapex-Mobilhy Regional Evapotranspiration Experiment
The HAPEX-MOBILHY (Hydrologic-Atmospheric Pilot Experiment - Modelisation du Bilan Hydrique) regional evapotranspiration experiment was conducted in the south-west of France during the...
Methods for Determining Actual Evapotranspiration in Plots
The major methods used at INRA since 1965 for determining actual evapotranspiration (AET) in plots are reviewed in this paper. These procedures involve either direct determination (weighing...
Atrazine in Subsurface Drain Water in Southern Louisiana
Atrazine was applied preemergent to corn on subsurface drained and undrained plots. Atrazine soil concentration and concentration and loss in drain water were determined for 243 days after...
Visual Estimates of Flume and Weir Operating Conditions
