Is Salt Lake City Water Safe to Drink?
The short answer: it meets all federal standards. The longer answer involves PFAS, arsenic, haloacetic acids, and EWG health guidelines that are stricter than federal law. Here's the full picture.
Salt Lake City’s tap water is legal. It meets every federal EPA maximum contaminant level. The Salt Lake City Department of Public Utilities publishes an annual Consumer Confidence Report showing compliance across all regulated parameters.
So — is it safe?
That question is more complicated than a compliance certificate suggests. Here’s the full, honest picture.
What “Safe” Means Under Federal Law
The EPA sets maximum contaminant levels (MCLs) for drinking water. Water that meets these standards is considered safe for public consumption. The key context: most of these limits were established in the 1990s and haven’t been comprehensively updated since. They’re based on the risk-assessment science available at the time and reflect a balance between health protection and the cost and feasibility of utility-scale treatment.
SLC’s water meets federal standards. That is a meaningful statement. It means the water has been treated and tested against legally established thresholds. It is not raw river water.
What the EWG Data Shows
The Environmental Working Group (EWG) maintains the Tap Water Database — a resource that takes the same utility testing data submitted to regulators and compares it against EWG’s own health guidelines, which are based on more recent research and are generally far stricter than federal MCLs.
For Salt Lake City’s water system, the EWG database identifies 16 contaminants detected above EWG health guidelines, including:
Arsenic — 135x the EWG health guideline
Arsenic is a naturally occurring element in Utah geology. The EPA’s legal limit is 10 parts per billion. EWG’s guideline is 0.004 ppb — reflecting research on cumulative long-term exposure risk at lower concentrations than the federal standard was designed to address. SLC’s detected level is within the federal limit but far above EWG’s threshold.
PFAS — Detected in 2024
The SLC Department of Public Utilities announced in 2024 that PFAS (perfluorohexane sulfonate / PFHxS) was detected at approximately 7.1–7.8 parts per trillion. This is below the new EPA MCL finalized in 2024 for some PFAS compounds, but it represents a detection of “forever chemicals” in the municipal supply. The EPA’s new PFAS standards are among the first ever set for these compounds.
Dichloroacetic acid — 101x the EWG health guideline
A disinfection byproduct formed when chlorine reacts with organic material in the Wasatch mountain watershed source water. Within federal limits but above EWG’s health threshold.
The Honest Assessment
SLC water is not immediately dangerous. People have been drinking it for generations without obvious mass health consequences from contaminant exposure at these levels.
What the EWG data represents is a more cautious view of long-term, cumulative risk — particularly for:
- Pregnant women and infants, who are more sensitive to some contaminants
- Families with young children who will drink the water for years
- Health-conscious households who want to minimize exposure to PFAS and arsenic as a precaution
The question of whether these levels are “safe enough” is a personal risk tolerance decision, not a regulatory one. Federal compliance tells you the minimum legal standard was met. It doesn’t tell you whether more cautious exposure reduction makes sense for your household.
What You Can Do
Option 1: Nothing different.
If you’re comfortable with federal compliance levels and not in a higher-sensitivity household, that’s a reasonable position. SLC water is legally safe.
Option 2: Point-of-use filter at the kitchen tap.
An under-sink reverse osmosis filter addresses arsenic, PFAS, and haloacetic acids at the kitchen faucet specifically — drinking and cooking water. Blue Logic includes a free under-sink RO system (valued at $1,000) with any whole-home filtration system purchase.
Option 3: Whole-home reverse osmosis.
For families who want comprehensive coverage — including in bathing water (PFAS can be absorbed through skin and inhaled from steam) — a whole-home RO system addresses arsenic, PFAS, and disinfection byproducts at every tap. Also solves SLC’s hard water (~12 GPG) and chlorine taste/odor simultaneously.
Option 4: Get your water tested first.
SLC’s water quality varies somewhat by neighborhood based on the active blend of sources. A free in-home water test from Blue Logic gives you the actual hardness and chlorine reading for your specific tap — and your specialist will walk you through the EWG data for your area.
The Bottom Line
Salt Lake City water is legally safe. It meets federal standards.
It also contains PFAS, arsenic above EWG health guidelines, and haloacetic acids from chlorination — in a regulatory environment where the science supporting those EWG thresholds is legitimate and growing.
Whether that’s acceptable for your household is yours to determine. What Blue Logic offers is the clearest possible starting point: a free water test, a plain-English explanation of what’s in your water, and a transparent recommendation — no pressure, no obligation.
