The verdict
Equistar Chemicals LP lands in the middle third by violation volume (44), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (715; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 9% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
