The health risk for Gatlinburg

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 37738 Tap Water

What's in ZIP 37738 tap water?

ZIP 37738 has 2 detected contaminants below EPA limits in this dataset. N-ethyl perfluorooctanesulf... measured closest to its guideline.

Will boiling ZIP 37738 tap water remove N-ethyl perfluorooctanesulf...?

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 37738, a certified filter is more reliable.

Do basic pitcher filters remove N-ethyl perfluorooctanesulf...?

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.
