Santa Clara City standing, high SDWIS violation third
0% of 415 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: UCMR5 tested, none detected. Population rank #5,135 of 29,740 among systems serving 500+.
The verdict
Santa Clara City sits in the upper third of the sitemap cohort by violation count (415), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (9,000; 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 tested this system and reported no PFAS above the minimum reporting level.
