Water Quality Snapshot: Clarinda Water Plant
Clarinda Water Plant is a local-owned community water system that delivers drinking water to 4,372 residents in Clarinda, Iowa (Page County) through 2,010 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 97 total violations for this system , of which 47 (48%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 22 monitoring and reporting violations are on file. The most recent violation on record dates to 2012.
The most frequently cited contaminant at this system is Surface Water Treatment Rule, recorded in 27 violations (TT, 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 8.2 ppt (parts per trillion). 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. Statewide, 127 of 152 UCMR5-tested systems have reported PFAS detections (83.6%).
Clarinda Water Plant's 97 violations sit above the Iowa average.
All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
1 PFAS "forever chemicals" detected in testing under EPA's UCMR5 monitoring program.
