535 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 4% is middle-third health share (≤ 23%). Population rank #27,834 of 29,740 among systems serving 500+.
The verdict
Lehigh Elementary School sits in the upper third of the sitemap cohort by violation count (137), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (535; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 4% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
