I am worried about PFAS, or I am on a private well

Forever chemicals near a contamination source, or untested well water.

PFAS are not removed by standard filters and need a specific lab test. The right EPA method depends on the sample type; for drinking water, methods 533 and 537.1 are standard. Private wells are not covered by public water testing, so they need their own panel.

What to do

  1. Use a dedicated PFAS drinking-water test (EPA method 533 or 537.1).
  2. On a well, also run a general panel for bacteria, nitrate, and metals.
  3. If PFAS results are high, choose treatment proven to reduce PFAS.

Where to go next

General information to help you find the right test and an accredited lab. This is not medical, legal, or safety advice. For a confirmed exposure or a health concern, talk to a qualified professional, and always confirm a lab's current accreditation with the certifying body.
