The short answer for Coos Bay
Coos Bay tap water has 7 detected contaminants, currently below EPA limits (tested November 2022). Arsenic measured closest to the threshold. See the full compound-by-compound report.
The health risk for Coos Bay
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Arsenic was detected below EPA limits. A certified filter can still add an extra layer of protection.
Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.

Frequently Asked Questions about ZIP 97420 Tap Water
What's in ZIP 97420 tap water?
ZIP 97420 has 7 detected contaminants below EPA limits in this dataset. Arsenic measured closest to its guideline.
Will boiling ZIP 97420 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 97420, 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 97420?
Public records identify COOS BAY NORTH BEND WTR BRD as a primary water system associated with ZIP 97420. Service boundaries can vary by address, so confirm exact service with the utility.
