The short answer for Kula

Kula tap water has 1 detected contaminant, currently below EPA limits (tested October 2025). 6:2 FTS measured closest to the threshold. See the full compound-by-compound report.

The health risk for Kula

PFAS traces were detected in local water tests, though levels are currently below EPA limits. Since no amount of PFAS is considered completely safe by health researchers, a certified filter adds a meaningful layer of protection, especially for children.
  • PFAS or other chemicals detected; no confirmed exceedances in multiple samples.

Frequently Asked Questions about ZIP 96790 Tap Water

What's in ZIP 96790 tap water?

ZIP 96790 has 1 detected contaminant below EPA limits in this dataset. 6:2 FTS measured closest to its guideline.

Will boiling ZIP 96790 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 96790, 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.
