BHC-GAMMA standing, high-volume SDWIS third

BHC-GAMMA sits in the upper third of this extract by raw violation count (50,797), 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 sits mid-pack at 5.2 violations per affected system (mid load (≤ 5.8 violations per affected system)). None of the recorded BHC-GAMMA violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #47 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.
