Is tap water in Saint Paul (55103) safe to drink?
- Saint Paul, MN
- Greater East Side
The short answer for Saint Paul (55103)
St. Paul tap water has 9 detected contaminants, currently below EPA limits (tested August 2022). Perfluoroheptanoic acid measured closest to the threshold. See the full compound-by-compound report.
The health risk for St. Paul
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Perfluoroheptanoic acid (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 55103 Tap Water
What's in ZIP 55103 tap water?
ZIP 55103 has 9 detected contaminants below EPA limits in this dataset. Perfluoroheptanoic acid measured closest to its guideline.
Will boiling ZIP 55103 tap water remove Perfluoroheptanoic acid?
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 55103, a certified filter is more reliable.
Do basic pitcher filters remove Perfluoroheptanoic acid?
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.
