Abstract
In Northern Alberta, Canada, large volumes of low-grade ‘lean’ oil sand (LOS) overburden are translocated during the surface mining of oil sands and remain in future reclaimed landscapes. The objectives addressed in this paper are to (a) characterise the on-site petroleum hydrocarbon (PHC) content of LOS; (b) evaluate the effect of LOS temperature on rates of carbon dioxide (CO 2 ) flux and PHC biodegradation and (c) evaluate the potential for PHC to leach from LOS into groundwater. The results show that LOS is predominantly composed of heavier F3 and F4 PHC fractions, the temperature appears to affect carbon dioxide fluxes and PHC degradation rates and it is unlikely that the presence of LOS in reclamation soils will release significant quantities of PHC into groundwater.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
