Turbidity standing, mid-volume SDWIS third

Turbidity lands in the middle third by violation volume (1,581), large enough for peer comparisons but not one of the handful of analytes that dominate the fleet-wide SDWIS ledger. Load is concentrated: 12.5 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 Turbidity violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #99 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.
