Littlestown Boro standing, high SDWIS violation third

UCMR5 detected 6 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 2% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #5,985 of 29,740 among systems serving 500+.

The verdict

Littlestown Boro sits in the upper third of the sitemap cohort by violation count (464), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (7,300; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 2% (middle-third health share (≤ 23%)). UCMR5 detected 6 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
