ASDWA Publishes New PFAS Lab Testing Primer for States and Water Systems

This post was originally published on this site

New ASDWA Logo 008ASDWA has published its new “Per- and Polyfluoroalkyl Substances (PFAS) Laboratory Testing Primer for State Drinking Water Programs and Public Water Systems.” The primer was developed by the ASDWA PFAS Workgroup with the help of Brandon Kernen from the New Hampshire Department of Environmental Services (who is one of the 27 state workgroup members). The document provides guidance and an overview of options and issues for state drinking water programs that are associated with testing for PFAS in water samples collected from public water systems. The document is divided into eight topics:

  1. Selecting an analytical method
  2. Finding a qualified laboratory
  3. Specifying a list of compounds and the form that each PFAS needs to be reported in
  4. Specifying reporting limits
  5. Technical issues that cause variability in testing results
  6. Sample collection procedures
  7. Interpreting results
  8. USEPA’s ongoing work to develop new analytical methods
