Water Quality Snapshot: PAOLI WATER DEPARTMENT

PAOLI WATER DEPARTMENT is a local-owned community water system that delivers drinking water to 3,677 residents in ORLEANS, Indiana (Orange County) through 1,651 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 494 total violations for this system , of which 23 (5%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 445 monitoring and reporting violations are on file. The most recent violation on record dates to 2014.

The most frequently cited contaminant at this system is LASSO, recorded in 31 violations (MR). This system was sampled under EPA's UCMR5 PFAS monitoring program and no PFAS compounds were detected above the minimum reporting level.

Across Indiana, EPA tracks 3,967 public water systems serving 5,774,616 people, with 352,710 cumulative violations and 35,932 health-based violations on record. About 96% of systems in the state carry at least one violation, and state-wide the average per system is 88.9 violations. PAOLI WATER DEPARTMENT's 494 violations sit above the Indiana average. Statewide, 93 of 229 UCMR5-tested systems have reported PFAS detections (40.6%).
