The short answer for Jefferson

Jefferson tap water has 5 contaminants above EPA guidelines, including PFPeA at 54.7× the limit (tested November 2023). See the full compound-by-compound breakdown and filter recommendations.

The health risk for Jefferson

PFAS ('forever chemicals') have been detected above EPA limits in this water system's most recent tests. These synthetic chemicals do not break down in the body and are linked to a range of health effects. A certified filter is strongly recommended.

Frequently Asked Questions about ZIP 75657 Tap Water

What contaminants are above EPA limits in ZIP 75657?

ZIP 75657 has 5 contaminants above EPA health guidelines in the latest available data, including PFPeA at 54.7x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 75657 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 75657?

Public records identify EAST MARION COUNTY WATER SUPPLY CO as a primary water system associated with ZIP 75657. Service boundaries can vary by address, so confirm exact service with the utility.
