The short answer for Big Rock
Big Rock tap water has PFBS above EPA guidelines (tested December 2023). See the full report with all tested compounds and filter options.
The health risk for Big Rock
- PFBS above limit.
PFBS (a PFAS 'forever chemical') was detected above EPA limits. These filters are independently certified to reduce common drinking-water contaminants.
Here's what actually removes PFAS from your water
The right filter eliminates PFAS at the tap. But not all filters do - and the type you choose matters for your home.
Common pitchers like Brita do not remove PFAS. You need a filter independently certified to NSF P473 (for pitcher filters) or NSF/ANSI 58 (for reverse osmosis systems). All three options below carry the relevant certification.

Frequently Asked Questions about ZIP 37023 Tap Water
What contaminants are above EPA limits in ZIP 37023?
ZIP 37023 has PFBS above EPA health guidelines in the latest available data. The full table on this page lists every tested compound and its measured level.
Will boiling ZIP 37023 tap water remove PFBS?
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 PFBS?
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 37023?
Public records identify NORTH STEWART UTILITY DISTRICT as a primary water system associated with ZIP 37023. Service boundaries can vary by address, so confirm exact service with the utility.
