Aldicarb sulfone standing, mid-volume SDWIS third

Aldicarb sulfone lands in the middle third by violation volume (15,483), 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 4.8 violations per affected system (mid load (≤ 5.8 violations per affected system)). None of the recorded Aldicarb sulfone violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #87 by violation volume.
