Frequently Asked Questions about ZIP 97231 Tap Water

What's in ZIP 97231 tap water?

ZIP 97231 has 5 detected contaminants below EPA limits in this dataset. Arsenic measured closest to its guideline.

Will boiling ZIP 97231 tap water remove Arsenic?

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 97231, a certified filter is more reliable.

Do basic pitcher filters remove Arsenic?

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 97231?

Public records identify PORTLAND WATER BUREAU as a primary water system associated with ZIP 97231. Service boundaries can vary by address, so confirm exact service with the utility.
