Abstract
Sixteen planned repairs of pipe leaks in two distribution systems were investigated in 2004‐2005 to study the occurrence of microbial contamination associated with repair activities in full‐scale distribution systems. Soil and water samples were collected in pipe trenches, and distribution system water was collected at consumers— homes and at flushed hydrants. The frequency of detection of fecal microbial indicators in the soil and water surrounding the mains was low. Evidence of contamination in distribution system water (based on total coliforms, Escherichia coli, and aerobic endospores) was obtained at seven of the sixteen sites. The 17 positive samples (of a total of 424) were almost all collected during flushing; results suggested that adequate pipe flushing after a repair has been completed is an effective way to minimize contamination for this type of repair. Loss of chlorine residuals and turbidity peaks were also observed outside the repair areas.

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
