Consumer Confidence Rule standing, high-volume SDWIS third

Consumer Confidence Rule sits in the upper third of this extract by raw violation count (201,666), 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: 6.9 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 Consumer Confidence Rule violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #8 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.
