Frequently Asked Questions about ZIP 53547 Tap Water

What's in ZIP 53547 tap water?

ZIP 53547 has 1 detected contaminant below EPA limits in this dataset. Nitrate + Nitrite measured closest to its guideline.

Will boiling ZIP 53547 tap water remove Nitrate + Nitrite?

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 53547, a certified filter is more reliable.

Do basic pitcher filters remove Nitrate + Nitrite?

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.
