Alabaster Water Board standing, high SDWIS violation third
UCMR5 detected 8 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 4% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #1,341 of 29,740 among systems serving 500+.
The verdict
Alabaster Water Board sits in the upper third of the sitemap cohort by violation count (133), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (41,061; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 4% (middle-third health share (≤ 23%)). UCMR5 detected 8 PFAS compounds (upper-third PFAS panel (> 4 compounds)).

How many violations vs. how serious, among peer systems
Alabaster Water Board plotted against 29 peer public water systems (500+ people served), by total violation count (x) and the share of those violations that are health-based (y). The crosshair sits at this sample's own median on each axis. A high violation count does not automatically mean a serious record: most monitoring and reporting violations are minor, not health-based.
