Frusi Water Treatment Plant is a federal-owned community water system that delivers drinking water to 35,784 residents in Fort Riley, Kansas (Geary County) through 5,900 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 58 total violations for this system , of which 39 (67%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 16 monitoring and reporting violations are on file. The most recent violation on record dates to 2019.

The most frequently cited contaminant at this system is TTHM, recorded in 24 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 7 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 21.1 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Kansas, EPA tracks 957 public water systems serving 2,894,673 people, with 84,344 cumulative violations and 33,424 health-based violations on record. About 99% of systems in the state carry at least one violation, and state-wide the average per system is 88.1 violations.
