Water Quality Snapshot: Boonville PWS
Boonville PWS is a local-owned community water system that delivers drinking water to 7,964 residents in Boonville, Missouri (Cooper County) through 3,190 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 129 total violations for this system , of which 90 (70%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 23 monitoring and reporting violations are on file. The most recent violation on record dates to 2020.
The most frequently cited contaminant at this system is TTHM, recorded in 86 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 5.1 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.
Across Missouri, EPA tracks 2,823 public water systems serving 5,855,885 people, with 201,695 cumulative violations and 54,821 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 71.4 violations.
