How we grade states Grades are based on actual EPA enforcement data — MCL violations and lead levels measured against the 15 ppb federal action level. We do not use MCLG-based detections, which are aspirational zero-tolerance goals that would make nearly every state look dangerous. Read our full methodology →

About Utah Drinking Water

Utah is served by 297 community water systems covering 319 communities across 29 counties. 98.4% have no open violation on record.

Lead was detected in 300 communities, with a median of 2.20 ppb — 15% of the federal action level. A further 19 reported none detected. That share is a state reporting convention rather than a measure of water quality, so it is stated separately rather than averaged in.

PFAS has been tested at 37.3% of communities here, and 1 are above the limits EPA set in 2024. Coverage matters: states that test more find more, so this figure is not comparable with a state that has tested less.

Frequently Asked Questions

Is Utah tap water safe to drink? ▼
98.4% of communities have no open violation on record. 1 have PFAS above the federal limit set in 2024, which is the main open concern.
Does Utah have a lead problem? ▼
8 water systems report a 90th-percentile lead result at or above the 15 ppb action level. The action level is a treatment trigger, not a legal maximum, and 19 communities report no detection at all.
How complete is the data for Utah? ▼
Lead results are reported for 100.0% of communities and PFAS for 37.3%. Where a figure is missing it is shown as not reported rather than assumed safe.
How does Utah compare with other states? ▼
We do not rank states against each other. Lead reporting completeness ranges from under 20% to 100% depending on the state, so a national ranking would compare filing practice rather than water quality.
