Frequently Asked Questions about ZIP 86403 Tap Water

What contaminants are above EPA limits in ZIP 86403?

ZIP 86403 has 7 contaminants above EPA health guidelines in the latest available data, including Perfluorobutanesulfonic acid at 297.3x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 86403 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 86403, 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 86403?

Public records identify LAKE HAVASU CITY OF as a primary water system associated with ZIP 86403. Service boundaries can vary by address, so confirm exact service with the utility.

When was ZIP 86403 tap water last tested?
