Is tap water in St. Cloud (56301) safe to drink?
- St. Joseph, MN
- Saint Cloud, MN
The short answer for St. Cloud (56301)
Rockville tap water has 15 detected contaminants, currently below EPA limits (tested June 2024). Perfluorobutanesulfonic acid measured closest to the threshold. See the full compound-by-compound report.
The health risk for Rockville
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Perfluorobutanesulfonic 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 56301 Tap Water
What's in ZIP 56301 tap water?
ZIP 56301 has 15 detected contaminants below EPA limits in this dataset. Perfluorobutanesulfonic acid measured closest to its guideline.
Will boiling ZIP 56301 tap water remove Perfluorobutanesulfonic 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 56301, a certified filter is more reliable.
Do basic pitcher filters remove Perfluorobutanesulfonic 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 56301?
