Utah Water quality · UT # Utah Water Quality (2026) Last updated: June 2026 ![Clear water flowing from a polished chrome kitchen faucet into a glass](/assets/hero-water-quality-COGzm6w_.jpg) Mountain snowmelt and groundwater produce hard water in most Wasatch Front communities. Our Utah coverage focuses on the 1 metros below. Each city page lists the utility's water source, hardness in grains per gallon, contaminants flagged above EWG's stricter health guideline, and the whole-house system that fits that specific profile, not a generic recommendation copied across the state. How to read the numbers on this page Every U.S. utility we cover meets the federal EPA legal limits for drinking water. Figures flagged as _"above the health guideline"_ refer to the stricter, non-enforceable benchmark published by the Environmental Working Group (EWG), **not** a legal violation. We share these figures so households can decide whether they want extra filtration - they are not a statement that the water is unsafe or illegal to drink. Always check your utility's annual Consumer Confidence Report (CCR) and the [EWG Tap Water Database](https://www.ewg.org/tapwater/) for the most current data on your zip code. ## Common contaminants flagged across Utah Across the Utah cities we cover, these are the contaminants most often reported above EWG's health guideline.
