Frequently Asked Questions about ZIP 17584 Tap Water

What contaminants are above EPA limits in ZIP 17584?

ZIP 17584 has 4 contaminants above EPA health guidelines in the latest available data, including PFPeA at 7.4x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 17584 tap water remove PFPeA?

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 PFPeA?

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.

Who provides tap water in ZIP 17584?
