The task

Willowbrook wellfield — the May 2024 pumping of PW-1 The district ran two pumping runs on production well PW-1. A four-rate step-drawdown test on 13 May sized the pump and checked the well's efficiency; then, from 2024-05-14T00:00, PW-1 was pumped at a nominally constant rate for 72 hours. Water levels were logged in PW-1 and in observation wells OBS-1..OBS-4, 20–400 m away, from three days before the constant-rate …

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
