Abstract
Permeable reactive barriers (PRBs) are used worldwide for the remediation of contaminated groundwater in the subsurface. This paper showcases a PRB installed in an acid sulfate soil rich ground to neutralize acidic groundwater. Recycled concrete has been used as the reactive material. Its performance is monitored over 8 years and has shown promising results for treatment in the long-term by maintaining a neutral pH and removing heavy metals from groundwater. Heavy metals (Al and Fe) precipitate out of solution and armor the reactive surfaces of recycled concrete, which leads to a decrease in the efficiency. Longevity of the PRB is predicted considering the rate of exhaustion of reactive material, rate of precipitation of secondary minerals and the groundwater flow at field site.

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
