Is St. Francis tap water safe to drink?
- Stanford, MN
- Saint Francis, MN
The short answer for St. Francis
St. Francis tap water has 8 detected contaminants, currently below EPA limits (tested June 2024). Perfluorohexanesulfonic acid measured closest to the threshold. See the full compound-by-compound report.
The health risk for St. Francis
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Perfluorohexanesulfonic 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 55070 Tap Water
What's in ZIP 55070 tap water?
ZIP 55070 has 8 detected contaminants below EPA limits in this dataset. Perfluorohexanesulfonic acid measured closest to its guideline.
Will boiling ZIP 55070 tap water remove Perfluorohexanesulfonic 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 55070, a certified filter is more reliable.
Do basic pitcher filters remove Perfluorohexanesulfonic 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.
Who provides tap water in ZIP 55070?
Public records identify SAINT FRANCIS as a primary water system associated with ZIP 55070. Service boundaries can vary by address, so confirm exact service with the utility.
