I’m seeking CEU-eligible training on interpreting continuous monitoring data for contamination control; our SCADA shows recurring 0.04–0.06 NTU spikes and about [redacted]/L free chlorine dips from 02:00–04:00 in Zone 3, and I need better methods to separate sensor noise from ingress risk. Prefer courses with hands-on datasets, time-series QA/QC and basic SPC (R or Python), and recognition by state operator boards — what offerings improved your decision-making?
