Sampling on sites contaminated by PFAS

As a protector of human health and the environment, the EPA has developed this document to guide consultants investigating the presence of per- and poly- fluoroalkyl substances (PFAS) in soil, groundwater and surface water as part of a contaminated land assessment.

As PFAS are highly leachable and bioaccumulative, it will not be sufficient to just measure soil and groundwater samples. Leachate and biota concentrations also need to be measured.

The guidelines advise consultants on

  • sampling methods to be undertaken to assess whether PFAs are present
  • what checks to conduct if PFAS are present on the site
  • further investigations to undertake if PFAS are present
