What's in Salt Lake City, UT tap water
3 contaminants in Salt Lake City, UT's water sat at or above a federal limit, led by Chromium at 4.0x the limit.
- !3 contaminants at or above a federal limit — worst is Chromium at 4.0x
- !15 of 27 core regulated contaminants reported — 12 never appear in this report
- ✓No open federal violations
+How this score is calculated
Every system starts at 100. Points come off for measured levels, for the federal violation record, and for how much of the core regulated set the utility actually reported. All three inputs are the utility's own published numbers and EPA's own records.
- −60 contaminants at or above a federal limit
- −0 contaminants within 20% of a limit
- −0 open health-based violations
- −0 open monitoring / reporting violations
- −0 health-based violations resolved in the last 5 years
- −6 core regulated contaminants never reported (15/27)
A 90–100 · B 80–89 · C 70–79 · D 60–69 · F below 60. A system reporting under a third of the core set is capped at C however clean its numbers look — a short report is not a clean bill of health.

- Chromium4.0× the federal limit0.4 mg/L · limit 0.1 mg/L
higher than 95% of U.S. systems
- Lead1.1× the federal limit0.016 mg/L · limit 0.015 mg/L
There is no safe level of lead; it harms brain development in children and raises blood pressure in adults. The EPA sets an action level, not a health goal above zero.
Higher than 95% of UT systems that report it · higher than 95% of U.S. systems
- Copper1.0× the federal limit1.3 mg/L · limit 1.3 mg/L
Short-term exposure causes stomach distress; long-term exposure can damage the liver and kidneys.
