Choose the right perspective

Choose someone who has worked on the same kind of problem you face, such as a groundwater source zone, drinking water treatment or a federal site, since methods and regulators differ. Also decide whether you need the view of someone managing remediation for a site owner or of a practitioner who designs and runs the investigation and treatment work.

Questions to take into the conversation

  1. 01How do you decide how far to delineate a PFAS plume before choosing a remedy?
  2. 02Which PFAS treatment or remediation technologies have held up in practice, and which have disappointed?
  3. 03How do changing PFAS regulations affect cleanup targets, schedules and budgets?
