Water Quality Snapshot: DECATUR WATERWORKS

DECATUR WATERWORKS is a local-owned community water system that delivers drinking water to 2,468 residents in DECATUR, Arkansas (Benton County) through 987 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 135 total violations for this system , of which 17 (13%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 46 monitoring and reporting violations are on file. The most recent violation on record dates to 2011.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 37 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 10 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Arkansas, EPA tracks 1,016 public water systems serving 3,049,400 people, with 53,437 cumulative violations and 21,598 health-based violations on record. About 94% of systems in the state carry at least one violation, and state-wide the average per system is 52.6 violations. DECATUR WATERWORKS's 135 violations sit above the Arkansas average. Statewide, 57 of 172 UCMR5-tested systems have reported PFAS detections (33.1%).
