Marbury Water System, Inc. standing, low SDWIS violation third
UCMR5 detected 7 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 5% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #5,280 of 29,740 among systems serving 500+.
The verdict
Marbury Water System, Inc. is in the lower third by violation count (20; lower-third violation load (≤ 21 violations)). A low count does not mean the system is unmonitored - monitoring and reporting violations still appear in SDWIS. Population served is large (8,670; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 5% (middle-third health share (≤ 23%)). UCMR5 detected 7 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
