New study concludes oil sands development has significantly increased PAH and DBT loadings in regional lakes; combined with effects of climate change, a “new ecological state” for the lakes

Green Car Congress

Standardized values (Z scores) of (A) visible reflectance spectroscopy (VRS) chlorophyll a inferences from the five lakes proximate to major oil sands operations as indicators of lake primary production; (B) total PAH concentrations and (C) total DBT concentrations from all six study sites.

Tailings Technology Roadmap project releases nine development roadmaps for treatment of oil sands fine tailings

Green Car Congress

The report provides nine different Tailings Technology Deployment (TDD) Roadmaps to accelerate the implementation of oil sands tailings solutions in Alberta. After oil sands ore is excavated from the ground (surface mining operations, not in situ production), warm water is added to wash the bitumen off the. sand and clay.

AER reports recovery of 337,000 gallons of bitumen from surface seeps at CNRL Primrose site; earlier event in 2009

Green Car Congress

HPCSS has been used in oil recovery in Alberta for more than 30 years, AER noted. However, there was an earlier, similar event of bitumen upwelling at the Primrose project initially reported in 2009. The heat softens the bitumen and the water dilutes and separates the bitumen from the sand. 2009 incident.

Microbes for Quick Clean Up of Toxic Byproducts from Heavy Crude and Oil Sands

Green Car Congress

Microbiologists from the University of Essex, UK are exploring the use of microbes to break down and remove toxic compounds from heavy crude and oil sands. These acidic compounds persist in the environment, taking up to 10 years to break down. Society for General Microbiology Autumn Meeting, 7 Sep 2009). Richard Johnson.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

New Study Finds That Oil Sands Development a Greater Source of Contamination Than Previously Realized; Challenges Existing Monitoring Program

Green Car Congress

A study by researchers in Canada and the US shows that oil sands development is a greater source of polycyclic aromatic compound (PAC) contamination to the Athabasca River and its tributaries than previously realized. Bitumen production in the Alberta oil sands has increased rapidly, rising from 482,000 to 1.3
