Is tap water in Nashua (ZIP 03063) safe to drink?
- Nashua
The short answer for Nashua (ZIP 03063)
Nashua tap water has 1 detected contaminant, currently below EPA limits (tested November 2023). 4:2 FTS measured closest to the threshold. See the full compound-by-compound report.
The health risk for Nashua
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
4:2 FTS (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.

Frequently Asked Questions about ZIP 03063 Tap Water
What's in ZIP 03063 tap water?
ZIP 03063 has 1 detected contaminant below EPA limits in this dataset. 4:2 FTS measured closest to its guideline.
Will boiling ZIP 03063 tap water remove 4:2 FTS?
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 03063, a certified filter is more reliable.
Do basic pitcher filters remove 4:2 FTS?
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.
