Public Notice in Drinking Water
10.0 violations per affected system (326,526 across 32,526) - dense load (> 5.8 violations per affected system).
EPA contaminant code: 7500
Public Notice standing, high-volume SDWIS third
Public Notice sits in the upper third of this extract by raw violation count (326,526), so the national record is thick enough that system-level lists below are a sample of a much larger compliance trail rather than a near-complete inventory. Load is concentrated: 10.0 violations per affected system (dense load (> 5.8 violations per affected system)), which usually means repeat findings on the same PWSIDs rather than one-off detections spread thin. None of the recorded Public Notice violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #5 by violation volume. Utilities listed below are ranked by cumulative violation count for this analyte; pair that with population served to gauge household exposure scale.
