Frequently Asked Questions about ZIP 74078 Tap Water

What's in ZIP 74078 tap water?

ZIP 74078 has 1 detected contaminant below EPA limits in this dataset. PFBA measured closest to its guideline.

Will boiling ZIP 74078 tap water remove PFBA?

No. Boiling does not remove PFAS, and the compounds can actually become more concentrated as water evaporates. To reduce PFAS at home, use a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis).

Do basic pitcher filters remove PFBA?

Most basic pitcher filters are only certified to NSF/ANSI 42 or 53, which do not cover PFAS. Look for a filter independently certified to NSF/ANSI P473 (activated-carbon pitcher or under-sink) or NSF/ANSI 58 (reverse osmosis) on the spec sheet.
