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

EPA sampled 14 of 21 public water systems here, together serving about 212,438 people. EPA detected PFBA at 13 ng/L. EPA has not set a drinking water limit for PFBA, so there is no figure to compare it against. Last sampled 9/6/2023.

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 Niagara 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.
