Solvent Release into a Sandy Aquifer 3: Enhanced Dissolution by Methanol Injection
Bibliographic record
Abstract
A field experiment involving a release of 5 litres of a mixture of chlorinated solvents (0.5 l of chloroform, 2.0 l of trichloroethylene, and 2.5 l of tetrachloroethylene) was carried out in a sandy, unconfined, shallow aquifer at Canadian Forces Base Borden, east of Toronto, Ontario, Canada. The dissolution of the chlorinated solvents into the groundwater was studied in detail for 220 days, then a methanol/water mixture was injected to study the possible enhancement of the dissolution. An effect of the methanol injection was only observed at a few sampling points, likely due to the distribution of the solvent as a laterally extensive, thin pool. This investigation shows that it is crucial to know the exact location of the dense nonaqueous phase liquids (DNAPL) in the subsurface when designing and performing remedial techniques at contaminated sites.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
