Is tap water in Suffolk (ZIP 23434) safe to drink?
- Suffolk
The short answer for Suffolk (ZIP 23434)
Suffolk tap water has 17 detected contaminants, currently below EPA limits (tested September 2025). 8:2 FTS measured closest to the threshold. See the full compound-by-compound report.
The health risk for Suffolk
- PFAS or other chemicals detected; no confirmed exceedances in multiple samples.
8:2 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 23434 Tap Water
What's in ZIP 23434 tap water?
ZIP 23434 has 17 detected contaminants below EPA limits in this dataset. 8:2 FTS measured closest to its guideline.
Will boiling ZIP 23434 tap water remove 8:2 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 23434, a certified filter is more reliable.
Do basic pitcher filters remove 8:2 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.
Who provides tap water in ZIP 23434?
Public records identify SUFFOLK, CITY OF as a primary water system associated with ZIP 23434. Service boundaries can vary by address, so confirm exact service with the utility.
When was ZIP 23434 tap water last tested?
The most recent test date used in this report is September 2025. EnviroClarity last refreshed this page on 2026-05-05.
Where can I find the official water quality report for ZIP 23434?
Every U.S. public water system is required to publish an annual Consumer Confidence Report (CCR). Contact SUFFOLK, CITY OF or visit their website for the latest official report covering ZIP 23434. The EPA also maintains a national CCR locator.
