Frequently Asked Questions about ZIP 53583 Tap Water

What's in ZIP 53583 tap water?

ZIP 53583 has 2 detected contaminants below EPA limits in this dataset. Atrazine measured closest to its guideline.

Will boiling ZIP 53583 tap water remove Atrazine?

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 53583, a certified filter is more reliable.

Do basic pitcher filters remove Atrazine?

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 53583?

Public records identify SAUK CITY WATERWORKS as a primary water system associated with ZIP 53583. Service boundaries can vary by address, so confirm exact service with the utility.
