The short answer for Coleraine (55744)
Grand Rapids tap water has 6 detected contaminants, currently below EPA limits (tested August 2024). Perfluorohexanesulfonic acid measured closest to the threshold. See the full compound-by-compound report.
The health risk for Grand Rapids
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
Perfluorohexanesulfonic acid (a PFAS 'forever chemical') 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.
No compounds above or close to EPA limits in available data.

Frequently Asked Questions about ZIP 55744 Tap Water
What's in ZIP 55744 tap water?
ZIP 55744 has 6 detected contaminants below EPA limits in this dataset. Perfluorohexanesulfonic acid measured closest to its guideline.
Will boiling ZIP 55744 tap water remove Perfluorohexanesulfonic 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 55744, a certified filter is more reliable.
Do basic pitcher filters remove Perfluorohexanesulfonic 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 55744?
Public records identify Grand Rapids as a primary water system associated with ZIP 55744. Service boundaries can vary by address, so confirm exact service with the utility.
