2.1 violations per affected system (286 across 138) - sparse load (≤ 3.7 violations per affected system).
EPA contaminant code: 4174
38-STRONTIUM-90 standing, mid-volume SDWIS third
38-STRONTIUM-90 lands in the middle third by violation volume (286), large enough for peer comparisons but not one of the handful of analytes that dominate the fleet-wide SDWIS ledger. Load is sparse: 2.1 violations per affected system (sparse load (≤ 3.7 violations per affected system)), so the footprint is wide relative to the raw count, many systems with few records each. None of the recorded 38-STRONTIUM-90 violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #104 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.
