Frequently Asked Questions about ZIP 33475 Tap Water

What contaminants are above EPA limits in ZIP 33475?

ZIP 33475 has 8 contaminants above EPA health guidelines in the latest available data, including PFOS at 3.2x the EPA guideline. The full table on this page lists every tested compound and its measured level.

Will boiling ZIP 33475 tap water remove PFOS?

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 PFOS?

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 33475?

Public records identify SOUTH MARTIN REGIONAL UTILITIES as a primary water system associated with ZIP 33475. Service boundaries can vary by address, so confirm exact service with the utility.
