Florida well-lab news
Dated notes from EPA, Florida DOH, and Florida DEP. Not headlines. Florida has not adopted 4 ppt as a kitchen-tap MCL for private wells.
Dated notes from agency pages, not invented headlines. Public-system MCLs do not bind a private well unless the item is about a private-well statute. Bacteria or nitrate on a lab sheet still goes to the health department. This site is not medical advice.

FederalEPA proposed keeping the PFOA and PFOS maximum contaminant levels at 4.0 ppt for public water systems, and letting requesting systems take until April 26, 2031 instead of April 26, 2029. The comment period closed July 20, 2026. EPA last updated that page July 23, 2026.
This is a proposal, not a final rule. It does not require a private-well owner to test or treat. Public-system MCLs do not bind a kitchen tap on a private well.

FederalIn the same window, EPA separately proposed rescinding MCLs for PFHxS, PFNA, HFPO-DA (GenX), and the Hazard Index mixture. That page was live when this note was written and is linked from the extension-rule page.
That action is still a proposal. Do not read it as those limits being gone. A private-well owner is not under that public-system rule either way.

FloridaFlorida DOH’s private-wells page states there is no state requirement for routine private-home well sampling or sampling at sale. DOH recommends bacteria and nitrate at least yearly, and lead every three years.
A closing or an annual kit is still the owner’s choice. If bacteria or nitrate fails, take the sheet to the county health department.

FloridaDEP’s Water Supply Restoration private-well sampling page (last modified March 20, 2026) says county public health units sample in contamination areas at no cost to the owner under the Water Supply Restoration Funding Program. Restoration is voluntary.
If you are in a known contamination area, ask the county health unit about that no-cost sample. It is not a statewide mandatory test at sale.
March 2022
FloridaDEP’s March 2022 PFAS Dynamic Plan states that EPA and Florida DOH established a lifetime drinking-water health advisory of 70 ng/L for PFOA and/or PFOS, and that DEP’s coordinated private-well follow-up has used that 70 ng/L HAL.
That is a health advisory used for follow-up, not a private-well MCL, and it is not the federal 4 ppt public-system number. Florida has not adopted 4 ppt for kitchen taps on private wells.
