Mapping History
Difficult, environmentally sensitive terrain combined with the fact that Canadian Western Natural Gas's new Banff pipeline will be laid in archaeologically rich ground posed a challenge...
Water Quality Regs: Staying Ahead
After a century in which water utilities could stay well ahead of most regulations simply by being responsible, professional organizations, they now seem to be playing catchup in a game...
Columbus Clear Wells
At an average of 8 million gal. each, six new clear wells at the Hap Cremean Water Plant in Columbus, Ohio represent the largest post-tensioned, reinforced concrete noncircular tanks ever...
Lessons From Kobe
On Jan. 17, Kobe, Japan became the first post-World War II, heavily populated, industrialized area to bear the full brunt of a high-magnitude earthquake. Engineers hope the resulting destruction...
Bioremediation Comes of Age
Only five years ago engineers and scientists met with EPA officials to weigh the merits of bioremediation as a hazwaste cleanup tool. Now bioremediation has become an accepted effective...
Seismic Design Guide for Natural Gas Distributors
This monograph presents an overview of the sources and geographical distribution of earthquakes, identifies earthquake hazards, and gives the implications of these hazards to gas distribution...
Doubling A Pipeline
The 36 in. natural gas pipeline built 32 years ago by Pacific Gas and Electric (PG&E) its subsidiary Pacific Gas Transmission (PGT) from Canadian fields to central California has...
Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...
Lunar Oxygen Production - A Maturing Technology
Research on oxygen production from lunar rock and soil has made significant progress in the past two years. An extensive series of experiments on natural and synthetic analogs has concentrated...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
Oxygen from Lunar Soil via Fluorination
This paper considers oxygen extraction from lunar soil via fluorination, for reasons of its high effectivity of oxygen release from most silicates. In addition to theoretical investigations,...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
Rehabbing for Remediation
Workers for Moses Lake detected trichloroethylene (TCE) in three of the city's water wells. The concentrations were low, around 5 to 15 parts per billion, just above the maximum...
Buoy Directional Wave Measurements Using Magnetic Field Components
Directional wave data can be estimated using the heave, pitch and roll motion of a discus buoy, which are conventionally measured by a pitch-roll sensor. To reduce the size and cost, this...
A Method for Locating Spikes in a Measured Time Series
Raw directional wave sample time series are frequently contaminated with spikes from various sources. The standard procedure in correctly editing these time series includes locating and...
Application and Benefits of Aquifer Recharge in Santa Fe, New Mexico
The Sangre de Cristo Water Company (SDCW) operates a water supply and treatment system that serves the City of Santa Fe, New Mexico, Water is supplied to the system by the City Well Field,...
Aquifer Storage and Recovery in the Floridan Aquifer System of South Florida
This paper describes the feasibility, construction, testing, and storage zone development of the Boynton Beach Aquifer Storage and Recovery (ASR) well, the first successful ASR project...
Optimization of the Design and Operation of Soil Vapor Extraction Systems
Volatile organic compounds (VOC's) immobilized within the soil unsaturated zone constitute a significant source of groundwater contamination. Soil vapor extraction systems (SVES's), which...
Site Characterization by Artificial Neural Networks
Recently, an optimal groundwater management model has been developed to treat groundwater remediation problems at Lawrence Livermore National Laboratory (LLNL). The objective of the model...
