Abstract
Although successful in laboratory studies, field applications of in situ remediation of chlorinated solvents in groundwater have met with limited success. This is most often attributed to the inability to deliver the amendment evenly throughout the target zone, especially in low permeability and heterogeneous materials. The goal of this research was to employ a prototype of a novel delivery system to evenly deliver amendment across the depth and breadth of the subsurface in a cost-effective method. The research was conducted at 42 Voyager Court, Toronto, ON where concentrations of vinyl chloride in groundwater were in excess of Ontario Ministry of the Environment guidelines (O.Reg.153/04). The subsurface consisted of sandy and clayey silt fill underlain by sandy silt till. The delivery system comprised 29, ” diameter, delivery points with small perforations along the length, installed in a fence perpendicular to groundwater flow, approximately 0.5 m upgradient of the area of concern. The delivery system used low flow rates (approximately 13 to 23 % of total

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
