PFAS in Utah Drinking Water

Maybe it is plain neighborhood curiosity, or maybe a move into Utah has you thinking harder than usual about what comes out of the tap. Either instinct is a good one. The figures below come from federal monitoring, and the office standing behind the state's drinking water is the Department of Environmental Quality (DEQ), through its Division of Drinking Water. Nothing here decides anything about a single home. It is the public record, organized so you can read it for yourself, which is exactly what is worth reviewing when evaluating an address.

EPA's UCMR 5 program (2021–2024) tested 50 public water systems in Utah for 29 PFAS compounds; 3 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 6% detection rate). Detections vary by water system — check the utility serving a specific Utah address.

Who regulates PFAS in Utah

Utah's drinking water sits under the Department of Environmental Quality, the DEQ, whose Division of Drinking Water administers the public-water-supply program the federal government delegates to the state. On PFAS, Utah largely works within the federal framework rather than setting its own enforceable drinking-water limit: residents are covered by the April 2024 rule (4 parts per trillion for PFOA and PFOS, 10 for PFHxS, PFNA, and GenX), with the DEQ responsible for enforcing those standards through public systems. That places Utah among the states leaning on the federal floor, but the work is run by a named office with a clear drinking-water division behind it.

What the EPA found in Utah

Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in Utahserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

Utah water systems with the most PFAS detections

These are the Utahutilities where EPA testing found PFAS the most often or at the highest levels. Being on this list doesn't automatically mean today's tap water is unsafe — some systems have added treatment since these samples were taken — but it means a conversation with the utility is worth having before you move in.

Which PFAS show up most in Utah

PFAS isn't one chemical — it's a family of thousands. Here are the specific compounds EPA picked up most often across Utah water systems. PFOA and PFOS are the two with the strictest federal limits (4 parts per trillion).

Drill down to a Utah city

How to read this Utah data

The numbers below have edges worth knowing before you lean on them. Coverage is the first: the federal UCMR5 testing looked at 29 PFAS compounds in public systems serving more than roughly 3,300 people, from 2021 to 2024, so private wells were never required to test and many small rural systems sit outside it. In Utah's more remote and well-served stretches, that means the public-system figures can read calmer than a private well's reality. The DEQ offers guidance for well owners who want their own testing, which is the right step there. And a detection from 2022 is a snapshot, not a promise about today's tap. The monitoring acronyms multiply faster than anyone can track, but the data underneath is worth a careful read.

PFAS in Utah: common questions

Is there PFAS in Utah drinking water?

Yes. EPA UCMR 5 monitoring (2021–2024) tested 50 public water systems in Utah; 3 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.

Does Utah set its own PFAS drinking-water limit?

Utah is among the states that rely on the federal standard rather than a separate state limit. Residents are covered by the April 2024 federal rule, which sets 4 parts per trillion for PFOA and PFOS, and the Department of Environmental Quality (DEQ) administers and enforces those limits across the state's public water systems.

How does the Utah DEQ regulate PFAS?

Through its Division of Drinking Water, the DEQ runs Utah's public-water-supply program and enforces the federal PFAS limits within it, including monitoring and follow-up when systems exceed the standards. Utah tends to track the federal rule rather than set stricter numbers, so the DEQ's role is largely implementing the 2024 EPA standards.

What is the Utah DEQ?

The DEQ is the Utah Department of Environmental Quality, the state agency overseeing environmental programs including drinking water, water quality, and contaminated-site cleanup. Its Division of Drinking Water is the contact point for public-water and well-water questions in Utah.

How do I check PFAS for a specific Utah address?

Use VetMyAddress to see the PFAS detections reported for the public water system serving any Utah address, alongside nearby military bases and industrial PFAS sources. The data comes from EPA UCMR 5, EPA TRI, and the DoD PFAS installation report.

What is the 2024 EPA PFAS limit?

In April 2024 the EPA set the first enforceable federal limits for PFAS in drinking water: 4 parts per trillion for PFOA and PFOS, and 10 ppt each for PFHxS, PFNA, and HFPO-DA (GenX), plus a Hazard Index for certain mixtures. Public water systems must complete initial monitoring by 2027 and come into compliance after that.

Are private wells covered by the EPA PFAS rule?

No. The federal limits apply to public water systems. Private well owners are responsible for their own testing and treatment, which is especially worth doing near a known PFAS source like a military base or industrial site.

Check a specific Utah address

State numbers tell you the pattern. An address report tells you what's actually in the water at yourkitchen sink — the matched utility, the PFAS detections on file, and every military or industrial source nearby. Whether it's for your family, your neighbors, or peace of mind.
