Worst PFAS result on federal record
PFAS detected, no federal limit set

EPA sampled 3 of 7 public water systems here, together serving about 32,827 people. EPA detected PFBA at 12 ng/L. EPA has not set a drinking water limit for PFBA, so there is no figure to compare it against. Last sampled 9/18/2024.

What this means

PFAS are industrial chemicals that EPA describes as breaking down only very slowly in the environment. In April 2024 EPA set the first enforceable national limits: 4 ng/L for PFOA and PFOS, 10 ng/L for PFHxS, PFNA and GenX.

These figures are county-level and come from EPA’s sampling of public water systems. They describe the worst result found in the county, not what comes out of any particular tap — that depends on which system serves the address, and on the plumbing in the building. A private well is not covered by this programme at all.

Request a test of your own supply.

This is Lee County's worst federal result, not a reading from your tap. Leave a number and a local water specialist will test it.

No obligation. Your details go to a local water specialist to arrange the test, and to no one else.
