Curious what's actually in the water around your corner of Alaska? You're in the right place. The agency standing behind these rules is the Alaska Department of Environmental Conservation, DEC, which runs the state's Drinking Water Program under the federal limits it administers. The figures below are pulled straight from federal testing — we didn't generate them, and they don't declare any single tap safe or unsafe. Think of them as a map of what the public record shows, the kind of thing worth reviewing when you're weighing an address, whether you're moving north or have called Alaska home for decades.
EPA's UCMR 5 program (2021–2024) tested 30 public water systems in Alaska for 29 PFAS compounds; 4 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 13% detection rate). Detections vary by water system — check the utility serving a specific Alaska address.
Alaska's drinking-water rules run through the Alaska Department of Environmental Conservation (DEC), which administers the state's Drinking Water Program and answers to the same federal standards as the rest of the country. Alaska has generally worked within the federal framework rather than enacting its own enforceable PFAS drinking-water limits, so for most residents the binding numbers are the federal ones DEC administers — notably the April 2024 rule setting PFOA and PFOS at 4 parts per trillion. Given how much of the state relies on small or remote systems, knowing which office is responsible matters even more than usual.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in Alaskaserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

Red triangles are military installations the Department of Defense has flagged for PFAS from firefighting foam. Orange dots are industrial facilities that reported PFAS to the EPA Toxics Release Inventory. If your future home sits near a cluster, that's a conversation worth having with the seller or landlord.
These are the Alaskautilities 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.
| Water system | Detections | Max value (ng/L) | vs 2024 MCL |
|---|---|---|---|
| COLLEGE UTILITIES CORPORATION | 4 | 0.01 | Below MCL |
| GOLDEN HEART UTILITIES | 4 | 0.01 | Below MCL |
| UNIVERSITY OF ALASKA - FAIRBANKS | 1 | 0 | Below MCL |
| EIELSON - AIR FORCE BASE | 1 | 0 | Below MCL |
PFAS isn't one chemical — it's a family of thousands. Here are the specific compounds EPA picked up most often across Alaska water systems. PFOA and PFOS are the two with the strictest federal limits (4 parts per trillion).
For decades the military trained with AFFF firefighting foam loaded with PFAS. It soaked into soil and groundwater and, in many places, traveled miles. If you're house-hunting near any of these Alaska installations, the address report will tell you exactly how close.

Looking at a specific Alaskacity? Each page below pulls the same federal data narrowed to that water system — useful whether you're relocating, buying, organizing your neighborhood around getting cleaner water, or just trying to find out what's in the tap and what's around you.
A few things make these records easier to read honestly. EPA's UCMR 5 program tested for 29 PFAS compounds from 2021 through 2024 — but only at public systems serving more than roughly 3,300 people. In a state where so many communities run small or remote water systems, and plenty of residents are on private wells, large stretches simply weren't required to test. So a quiet result above can mean "no one was asked to look," not "clean." And any detection is a moment in time, not a guarantee about today's tap. DEC offers guidance for private well owners worth tracking down. The federal acronyms multiply faster than the actual chemistry does.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 30 public water systems in Alaska; 4 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
Alaska has generally followed the federal framework rather than adopting its own enforceable PFAS drinking-water limits. For most residents that means the limits in force are the federal ones the Alaska Department of Environmental Conservation (DEC) administers, including the April 2024 rule capping PFOA and PFOS at 4 parts per trillion.
The Alaska Department of Environmental Conservation (DEC) runs the state's Drinking Water Program and enforces drinking-water rules in line with federal EPA standards. Rather than setting state-specific PFAS limits, DEC tends to administer the federal limits that apply to public systems statewide.
DEC is the Alaska Department of Environmental Conservation, the state agency responsible for environmental programs including drinking water. If you're looking for the office that handles water quality in Alaska, DEC is it.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any Alaska address, alongside nearby military bases and industrial PFAS sources. The data comes from EPA UCMR 5, EPA TRI, and the DoD PFAS installation report.
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.
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.
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.
