1,2-DIBROMO-3-CHLOROPROPANE standing, mid-volume SDWIS third

1,2-DIBROMO-3-CHLOROPROPANE lands in the middle third by violation volume (36,389), large enough for peer comparisons but not one of the handful of analytes that dominate the fleet-wide SDWIS ledger. Load sits mid-pack at 5.3 violations per affected system (mid load (≤ 5.8 violations per affected system)). Health-based share is only 1% - almost all of this analyte's trail is monitoring/reporting rather than MCL exceedance. Among 157 indexable contaminants, this page is #76 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.
