Abstract: Triassic core stratigraphy of the Wolfville Formation in the Bridgetown area, Nova Scotia and associated uranium in groundwater
Bibliographic record
Abstract
The town of Bridgetown, Nova Scotia, is considering switching its fresh water supply from surface water to groundwater to help lower operational and maintenance costs. Preliminary chemical analysis of the groundwater has shown elevated uranium concentrations. The purpose of this study is to determine if the source of uranium in the groundwater is within the Triassic Wolfville Formation aquifer, which underlies the Bridgetown region. Drill core from Paradise, near Bridgetown, and well cuttings from the test wells at Bridgetown were analyzed and logged to better understand the stratigraphy of the Wolfville Formation and to determine which, if any, horizons has elevated uranium that can be leached in the groundwater. Gamma logging of the Paradise drill core indicates that some layers within the core have twice the background levels of radiation, suggesting that the Wolfville Formation may indeed be the source of elevated uranium in the groundwater.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
