Simulated stream · synthetic data
Watch the anomaly model score water readings as they arrive.
Four simulated stations stream one reading per tick. Every new point is scored by a robust z-score baseline and an Isolation Forest — the same engine your workspace uses.

Red points = flagged by both robust z ≥ 3.5 and isolation score ≥ 0.6. A flag is an unusual pattern, not a confirmed contamination event.
1 · Clean & validate
Units, timestamps, duplicates and calibration metadata are checked before any scoring.
2 · Baseline
A trailing rolling median and MAD give a robust, outlier-resistant reference for every reading.
3 · Isolation Forest
Value, rate-of-change and deviation features are scored; only points unusual on both signals are flagged.
