Characterization of Oil Sands Naphthenic Acids in Oils Sands Process-Affected Waters Using Fluorescence Technology

View Lisa's Presentation (PDF)

Naphthenic acids represent the toxic component of oil sands process-affected water. A current challenge is the development of a rapid, accurate and accessible analytical technique to characterize naphthenic acids in process water. Fluorescence spectrophotometry is suggested and developed as a potential solution for both generating sample signatures or €śfingerprints€ť and quantitative analysis. Samples of oil sands process-affected waters produced fluorescence signals that differed from groundwater collected in the Athabasca region. A dilution series prepared with process water produced a linear response curve, following correction for inner filtering effects. Fluorescence spectrophotometry is a potentially powerful tool for characterizing and quantifying naphthenic acids in oil sands process-affected, surface, and ground waters.

Landslide Hazard Assessment, Town of Peace River

View Tai-Hoon's Presentation (PDF)

The Peace River area developed from the beginning of 1900s and was heavily urbanized by the late 1970s. Development extended its urban boundaries to the geologically immature valley slopes of the Peace River tributaries. Over the past 50 years a combination of precipitation and urban development on marginally stable slopes resulted in a number of landslides that often resulted in property damage to individual houses and community infrastructure. Such landslides can significantly affect community long–term planning and infrastructure development. In this study the general geology of the Peace River area and historic landslides will be described. Displacement and pore pressure monitoring records of these landslides will be summarised. New results from laboratory tests of samples obtained from recently drilled deep boreholes will also be presented. The characteristics of these landslides will be used to develop a landslide hazard map for the Peace River Area.

Janelle Murray (AECOM) had orginally been scheduled to speak but was unable. Sierra graciously agreed, on short notice, to speak in her place on behalf of Engineers without Borders. Sierra, a Civil Engineering student at the U of A, spoke about her recent experiences in Zambia. In addition her presentation, Sierra also provided the following links for those interested in further details about EWB:
