Abstract
Public Health Units (PHUs) in Ontario regularly monitor public beaches for E. coli levels as an indicator of the risk of recreational water-induced illness. Provincial guidance for beach water monitoring allows local flexibility in the beach monitoring process. We conducted a survey of public health professionals responsible for beach water management in Ontario PHUs to determine how monitoring practices differ across jurisdictions. We obtained data from 22 of the 29 PHUs that conduct beach water monitoring. Six health units reported meeting guidelines (27%) and four reported meeting historical water quality (18%) were important factors in deciding sampling frequency. Major challenges and limitations in monitoring that arose from the lag time between sampling and obtaining results were reported by 12 (55%). Predictive modelling has been trialled eight times across the province with varied results. This study provides an overview on the current state and future avenues for beach water monitoring in Ontario.

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
