Overview

PFOA is one of thousands of PFAS, man-made 'forever chemicals' once common in nonstick, waterproof, and stain-resistant products. They break down very slowly. EPA finalized a new limit in 2024 that utilities must meet by 2029.

In Florida, PFOA was found in 109 community water systems serving about 8,684,215 people. 107 of those readings were above the federal legal limit, together serving 8,539,674 people.

The highest reading relative to the limit was at Gonzalez Utilities Association, INC. in Escambia County, at 980% of it.

Where it comes from: Industrial discharge; firefighting foam; consumer products.

The standards

Legal limit (MCL)
4 ppt

Enforceable. A utility must stay at or under this.

Federal health goal (MCLG)
Not set

Health-based, not enforceable. Often lower than the limit, sometimes zero.

California public health goal
0.007 ppt

California OEHHA PHG (2024).

Health effects the EPA associates with it: Effects on cholesterol, the liver, the immune system, and thyroid. May increase the risk of certain cancers.

The health goal is set on health alone. The legal limit is set as close to it as is technically and economically feasible, so treatment cost and available technology are written into the number a utility is measured against. A system at or under the limit is meeting the standard it is required to meet. Both numbers are shown so the distance between them is visible.

What removes it

Three methods work, and only three: granular activated carbon, anion exchange resin, and reverse osmosis. Look for certification to NSF/ANSI P473 or 53 for PFOA and PFOS specifically, because a filter that reduces chlorine and taste may do nothing here. Carbon and resin both exhaust and have to be changed on schedule, since spent media passes PFAS straight through. Boiling makes it worse by concentrating what is there.

Treatment guidance describes the methods generally used for this contaminant. What your own tap actually carries depends on your plumbing and your service line as much as on the utility, which is what a test at the house tells you and an annual report cannot.
