Waldwick Water Dept standing, high SDWIS violation third
0% of 828 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: upper-third PFAS panel (> 4 compounds). Population rank #4,606 of 29,740 among systems serving 500+.
The verdict
Waldwick Water Dept sits in the upper third of the sitemap cohort by violation count (828), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (10,208; 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 9 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
