Water Quality Snapshot: SHENANDOAH WATER DEPT

SHENANDOAH WATER DEPT is a local-owned community water system that delivers drinking water to 4,925 residents in SHENANDOAH, Iowa (Page County) through 2,305 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 232 total violations for this system , of which 12 (5%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 116 monitoring and reporting violations are on file. The most recent violation on record dates to 1998.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 12 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 13 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Iowa, EPA tracks 1,795 public water systems serving 3,114,444 people, with 138,271 cumulative violations and 27,946 health-based violations on record. About 95% of systems in the state carry at least one violation, and state-wide the average per system is 77 violations. SHENANDOAH WATER DEPT's 232 violations sit above the Iowa average. Statewide, 127 of 152 UCMR5-tested systems have reported PFAS detections (83.6%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
