1. PFC-Template and Questionnaire for the pilot study on PFC (2017)
The template was prepared by Emanuele Ferretti and adapted a table reported in CONCAWE/NICOLE review on PFAS ( suggested by Jonathan Smith during the meeting in Amersfoort.

Type of monitoring:
Yes No
Unknown
Comments
Representative
Orientated at known or expected contamination
Non target analysis
Reasons of groundwater contamination by PFC*
via bank filtration
Fire-fighting foams drill ground at e.g. airports fire fighting water
Textile protection
Carpet protection
Paper and paperboard protection
Coating of metals and ceramics
Impregnation agents
Use of contaminated sludge (from paper industry)
Waste deposits
Leaky sewage water systems
Other reasons
please verify:
* Indication of several reasons is possible!
