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.

Who provides tap water in ZIP 55103?

Public records identify SAINT PAUL REGIONAL WATER SERVICES as a primary water system associated with ZIP 55103. Service boundaries can vary by address, so confirm exact service with the utility.
