Identifying PFAS Use in Your Facility

Sources of per- and polyfluoroalkyl substances (PFAS) in manufacturing aren't always obvious. This page is here to help manufacturers examine their operations for potential sources.

Look for common uses of PFAS

• Common uses include textile coatings (e.g., water-repellency), surfactants, degreasing (e.g., solvents), metal finishing (e.g., fume suppressants), polymers and resins, and AFFF
• Check your SDSs for products likely to contain PFAS
• Note listings described as Confidential Business Information (CBI) or proprietary as items of concern – contact your supplier or OTA for help

Check available CAS numbers against reportable definition

• Review draft TURA guidance and use reportable definition to check CAS # against existing databases
• Contact OTA to walk through one of our industry-specific PFAS identification questionnaires with an OTA technical assistance provider
• If no CAS numbers are available for fluorinated compounds, contact your supplier or OTA for technical assistance

Send a notification letter to your chemical or product supplier

• Use OTA’s template Supplier Notification Letter to contact your supplier and request information about PFAS in products you purchase from them
• Involve your purchasing department in this effort
• Keep records to demonstrate good faith effort

Contribute to developing product list

• The TURA program is developing a list of products confirmed to contain PFAS. If your supplier notifies you of products containing PFAS, please share this information with OTA.
