Morningside Heights WD / Erwin (T) standing, high SDWIS violation third
0% of 426 recorded violations are health-based - lower-third health share (≤ 1%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 0% is lower-third health share (≤ 1%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #8,158 of 29,740 among systems serving 500+.
The verdict
Morningside Heights WD / Erwin (T) sits in the upper third of the sitemap cohort by violation count (426), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (4,570; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is only 0% - almost all of this trail is monitoring or reporting. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
