Abstract
Contaminant concentration ratios are used commonly to distinguish between different sources of contamination and to evaluate contaminant attenuation in groundwater, soil air, soil, and sediment.Logarithmic-scale correlation (log-log) plots provide special capabilities in representing contaminant ratios.Log-log plots can reflect the ranges in concentrations over many orders of magnitude, the magnitude and ranges of concentration ratios, and whether ratios are constant or change with declining concentration.Declines in contaminant concentrations due to dilution and dispersion processes will not change contaminant ratios, and such data should plot along isoratio lines.If contaminant concentrations are reduced also by other attenuation processes such as sorption or biodegradation that affect one of the contaminants to a greater degree than the other, the ratio will change and the data will deviate from the isoratio line trends.Examples are given to illustrate the use of log-log plots in the interpretation of chemical data from sites of groundwater, soil air, and sediment contamination.

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
