Frequently Asked Questions about ZIP 77979 Tap Water

What contaminants are above EPA limits in ZIP 77979?

ZIP 77979 has 10 contaminants above EPA health guidelines in the latest available data, including 6:2 FTS at 10.2x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 77979 tap water remove 6:2 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 77979, a certified filter is more reliable.

Do basic pitcher filters remove 6:2 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.
