A study of contaminant remediation guidelines for soil and groundwater near an insecticide factory
Bibliographic record
Abstract
To calculate remediation objectives for 1,2-dichloroethane and 1,2-dichloropropane in soil and groundwater near a insecticide factory,procedures Tier 1 and Tier 2 were chosen from the Canadian Alberta SGRG tiered approach model.By using parameters suitable for our country,the generic Tier 1 guidelines were developed.The guidelines of the seepage sink soil are 6.2 μg /kg for 1,2-dichloroethane and 67 μg /kg for 1,2-dichloro-propane.The groundwater guidelines are 5 μg /L for both 1,2-dichloroethane and 1,2-dichloropropane.Tier 2 can adjust the Tier 1 guidelines based on a critical on-site survey.The seepage sink soil final remediation objectives are 11 μg /kg for 1,2-dichloroethane and 45 μg /kg for 1,2-dichloropropane.The groundwater final objectives are still 5 μg /L for both 1,2-dichloroethane and 1,2-dichloropropane.The adjustment of the guidelines was in accordance with the tiered approach theory.Note that the value of 1,2-dichloroethane in protecting of DUA pathway became restrictive due to site-specific characteristics.

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; a candidate call from one teacher head, not a consensus.
