PFAS Sampling Guidance

PFAS sampling is different from other types of sampling because PFAS are present in many things we use in our everyday life, such as water-resistant and stain-resistant products. PFAS can also be present in:

  • Personal care products such as cosmetics and lotions.
  • Insect repellants and sunscreens.
  • Pizza boxes and fast food wrappers.
  • Recycled paper products such as paper towels and notebook paper .
  • Sampling equipment--in the material of the equipment itself or due to PFAS being used in the manufacturing process.
  • Ordinary latex gloves.  (Because PFAS is in latex gloves, samplers  must use powderless nitrile gloves.)

Since PFAS are analyzed in such small quantities--parts per trillion--even the smallest cross-contamination could contribute to a false positive sample.   To learn more about which products contain PFAS and which do not, review the General PFAS Sampling Guidance document, below.   Then use the media-specific guidance document for the specific type of sampling you are interested in.

The guidance documents below are intended for technical staff.
