CASE STUDY - Moncton, NB Oulton Business School
The majority of the subsurface contamination was found present under one quarter of the building and associated cornerclassrooms. These classrooms were temporarily sealed off from the rest of the building for health and safety reasons. A large window and section of the brick wall was then removed to allow a mini-excavator access to the classroom. The concrete floor was also removed and the ...

Cleo Springs, Oklahoma - in-situ chemical oxidation case study
A gasoline spill occurred when a fuel tanker was forced off this curve in rural Oklahoma. Initial responders were unsuccessful in their effort to remove all of the contaminated soil. Cedar Creek Engineering was contracted to remediate the residual soil and groundwater contamination. Here a recovery well and reagent injection points are installed. The treatment process called for Fenton's reagent ...

Recovering from science: how far can we push?
Expecting recovery from science and its applications is a newly growing field in different countries, and there have been debates on its efficacy as a policy option. Noting the salience, this paper attempted to discuss the issue of cost recovery in the area of meteorological research. After a theoretical review, this research focused on the aeronautical meteorology case of Korea. As a policy ...

Evaluating DNAPL Recovery System Performance GeoTrax Survey - Case Study
Aestus performed our GeoTrax Surveys to asses the performance of a DNAPL recovery system installed within a waste pit at a hazardous waste landfill. The two remediation wells along our survey transect had been “clean” for two years prior to our confirmation survey work. The GeoTrax Survey results indicated that recovery wells have achieved significant reduction of DNAPLs near the ...

Aquifer storage recovery efficiency for saline groundwater regions as influenced by buffer storage volume and storage time
Abstract: Field experiments were carried out in a cavity type of Aquifer Storage Recovery well installed in an aquifer having highly saline native groundwater (EC = 28.4 dS m-1). Good quality canal water (EC = 0.46 dS m-1) was injected to investigate the effect of buffer storage volume (varying from 2000 –14000 m3) and storage time (varying from 2.5–70 ...

Determination of horizontal in-situ stresses and natural fracture properties from wellbore deformation
Accurate and low-cost information on in-situ stresses and fracture properties is critical in reducing well costs and increasing well recoveries. In this paper, a hybrid model based on the displacement back analysis is proposed for determining the in-situ stress magnitudes and fracture properties at the wellbore scale using wellbore displacements. The new methodology is an integration of ...

America Chung Nam: committed to the paper loop
China is not only the worlds biggest importer of scrap metals, it also hold this position with recovered paper. To satisfy its paper mills, China has to import huge volumes of recovered paper because the country is poor in forests to produce pulp and because domestic paper collection is still in its infancy. The world’s biggest exporter of recovered paper to China is America Chung Nam. With ...

Surfactant enhanced in-situ remediation of DNAPL impacted soil and groundwater - Montreal refinery
Abstract A Montreal chemical refinery reduced the dichlorobenzene and other dense non-aqueous phase liquid (DNAPL) impacts on the soil and groundwater where a railway line is adjacent to an above ground storage tank farm. Ivey-sol® surfactant mixtures were injected three times during a two week pilot test, into a series of in-situ wells. The soil and groundwater matrix experienced an induced ...

Technology for heavy oil and bitumen recovery with low water cut
The core of the technology resides in the reduction of oil viscosity and the respective production rate increase under the condition of oil layer heating. It is known, for example, that the heating of the layer with heavy oil up to 100°C theoretically leads to a 15 to 20 times production rate increase. The technology works on the principle of controlled automated continuous pumping of highly ...
