Frequently Asked Questions about ZIP 37665 Tap Water

What's in ZIP 37665 tap water?

ZIP 37665 has 1 detected contaminant below EPA limits in this dataset. 8:2 FTS measured closest to its guideline.

Will boiling ZIP 37665 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 37665, 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.
