Controlling Lead and Copper Corrosion and Sequestering of Iron and Manganese
With the recently enacted Lead and Copper Rule (LCR), many utilities are faced with the conflict of meeting the requirements of the Rule and controlling aesthetic problems caused by source...
Modeling Issues of Copper Solubility in Drinking Water
The paper discusses the application of a model to the solubility of copper in drinking water. This paper is the result of numerous forms of pitting corrosion and pipe failures. Monitoring...
The Effects of NOM and Coagulation on Copper Corrosion
Copper corrosion was examined in solutions containing natural organic matter (NOM) and in situations where NOM was removed by enhanced coagulation with alum or ferric chloride. Electrochemical...
Recovery and Recycling of Copper from Wastewater using Iron Coated GAC
The purpose of this study was to prepare composite adsorbents that could be packed into a column and have adsorption characteristics similar to Fe oxide. This adsorbent was targeted to...
Costs and Benefits of Meeting the San Francisco Bay Copper Objective by Regulating Small Treatment Plants
Metals in aquatic environments, even in very small amounts, are of concern because of potential toxicity to aquatic life forms. Copper is of particular concern in the San Francisco Bay...
TVO-92 Safety Analysis of Spent Fuel Disposal
Spent fuel from the TVO I and TVO II reactors is planned to be disposed of in a repository to be constructed at a depth of about 500 meters in crystalline bedrock. The fuel will be encapsulated...
The Copper-Clad Library
The design vocabulary for the new Phoenix Central Library includes saddlebags, power bellies, tensegrity and corrugated siding. The saddlebags are copper-clad, steel-framed core structures...
Future Supply of, and Demand for, Titanium, Copper and Lead
A literature survey has been conducted to assess the future world supply of, and demand for, titanium, copper and lead. These metals are candidates for the fabrication of containers for...
Validation of Source-Term Models Using Natural Analogues
A comparison is made between the predicted distribution of copper calculated by the AREST source-term code and the measured profiles for copper surrounding a bronze cannon that was emplaced...
Substrate Effects on Methanotrophic Trichloroethylene Degradation
Formate up to 1g/L had no significant enhancing effect on the degradation of trichloroethylene (TCE) by three mixed enrichments of methane-oxidizing bacteria. Methanol did not enhance...
In-Mine Hydroelectric Power Generating Station
Mines in the world are continually descending to greater depths in the search of mineral deposits. Water and energy usage are crucial to expansion. To help deal with this problem, Freeport...
Pressure-Treated Wood Effect on Marina Environment
Pressure treated Southern Pine and Douglas Fir are the most commonly used materials for marina construction in the United States. The preservatives currently used, creosote, chromated...
Use of Copper Slag for Construction Purposes
Standard laboratory test results on the fine- and coarse-grained fractions of a copper slag have been presented. Based on the results of these tests, the possible use of the fine fraction...
Technical Evaluation of a Copper:Silver Ion Swimming Pool Disinfection Unit
The paper reports on an investigation of a mock swimming pool setup on a laboratory scale. The study used indoor and outdoor simulated swimming pools to compare the efficacy of electrolytically...
Variability of Copper in the International Reach of the Similkameen River, British Columbia
All total copper concentrations measured in soft water during spring freshets were above the Canadian Water Quality Guidelines. Approximately 57% of all 108 observations over the three-year...
Stewardship 87
Stewardship 87 provides new linkages between land users, public agencies and the non-profit sector. It creates a totally new rapport between local governments (dependent upon ad valorem...
Application of Finite Strain Consolidation Theory for Engineering Design and Environmental Planning of Mine Tailings Impoundments
A knowledge of the consolidation behavior of mine tailings, during and after deposition, is important in estimating final impoundment capacity, rate and pore fluid expulsion during and...
