1,1,2,2-Tetrachloroethane standing, low-volume SDWIS third

1,1,2,2-Tetrachloroethane is in the lower third by violation volume (88). Sparse counts make each listed system more of the story, the table below is closer to the full affected set than it is for high-volume analytes. Load is sparse: 2.6 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 1,1,2,2-Tetrachloroethane violations in this extract are classified health-based; the trail is procedural. Among 157 indexable contaminants, this page is #115 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.
