Is tap water in Duluth (ZIP 55806) safe to drink?
- Duluth
The short answer for Duluth (ZIP 55806)
Duluth tap water has 3 detected contaminants, currently below EPA limits (tested March 2025). 8:2 FTS measured closest to the threshold. See the full compound-by-compound report.
The health risk for Duluth
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
8:2 FTS (a PFAS 'forever chemical') was detected below EPA limits. A certified filter can still add an extra layer of protection.
Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.

Frequently Asked Questions about ZIP 55806 Tap Water
What's in ZIP 55806 tap water?
ZIP 55806 has 3 detected contaminants below EPA limits in this dataset. 8:2 FTS measured closest to its guideline.
Will boiling ZIP 55806 tap water remove 8:2 FTS?
Boiling tap water can kill many pathogens, but it does not remove most chemical contaminants tracked in EPA monitoring. Several dissolved contaminants can even concentrate as water evaporates. For the chemical contaminants reported in ZIP 55806, a certified filter is more reliable.
Do basic pitcher filters remove 8:2 FTS?
Basic pitcher filters are typically rated for chlorine, taste, and odor (NSF/ANSI 42), not for the broader list of contaminants tracked in EPA monitoring. Match the certification (NSF/ANSI 42, 53, 58, or P473) to the specific compounds listed in this report before assuming a filter helps.
Who provides tap water in ZIP 55806?
Public records identify DULUTH as a primary water system associated with ZIP 55806. Service boundaries can vary by address, so confirm exact service with the utility.
