Abstract
It is well documented that urban runoff and roadside soils can become contaminated with particulate deposits, especially heavy metals, sourced from vehicles. However, phosphorous from vehicular sources has been given little consideration as a possible roadside contaminant. This paper examines the potential contamination of surface water (via runoff to storm drains and discharge to waterbodies) and groundwater (via roadside soil infiltration) by the phosphorous deposited onto pavement and road shoulders in the city of Waterloo, Ontario, Canada. Total and soluble reactive phosphorous concentrations in roadside soil and runoff samples were determined for two study sites. Subsequently, the results were statistically analyzed. Following comparison to other sources of urban runoff, it was concluded that roadways are a significant source of phosphorous in urban runoff, with high potential to impact surface water. Conversely, results of this work indicate that vehicular-sourced phosphorous does not pose a significant threat to groundwater.

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
