Industrial Waste Division PFAS Initiative Screening Evaluation Survey

Please review the list of potential PFAS sources below.  If you currently or have historically discharged wastewater into the sanitary sewerage system from any of the selected manufacturing operations or activities listed, please check them below and complete the corresponding section identified.

Section 1 – Electroplaters / metal finishers / circuit board manufacturers (40 CFR 413/433)
PFAS- containing chemicals, specifically those containing perfluoroctane sulfonate (PFOS) were used by electroplaters as a demister /defoamer/surfactant to control air emissions of hexavalent chromium beginning in the mid-1990s.  While hard chrome and decorative chrome platers using hexavalent chrome are the most likely sources, PFAS have also been found in wetting agents and other plating chemicals containing other metals and plastics.  Even if used many years ago, PFAS-containing chemicals may persist in plating tanks, etch tanks, sumps, air emission control systems and secondary containment pits.  Some chemicals identified as PFOS-free may still contain PFAS.  We are still learning about the behavior of these chemicals, and there are concerns that chemical changes may occur in plating and etch baths.  Platers in Michigan and Minnesota were found to have PFOS contamination in their wastewater years after they discontinued use of
PFOS-containing chemicals.


Section 2 – Paper and Packaging Manufacturers (40 CFR 430)
Paper and packaging manufacturers: Some paper and packaging manufacturers use PFAS coatings or treatments for oil and moisture repellency

Section 3 – Leather, Textile, Fabric and/or Carpet Treaters, Leather Tanneries (40 CFR 410/425)
Factory-applied repellents for stain, oil- and/or water-repellency have been known to contain PFAS.  Applications include protective coatings and leather, clothing or outerwear, umbrellas, tents, sails, architectural materials, carpets, and upholstery.

Section 4 – Manufacturers of parts with polytetrafluororethylene (PFTE) coatings (40 CFR 414)
A PFAS containing chemical, perfluorooctanoic acid (PFOA), is used in the process of making PFTE, which is a form of Teflon.  Our understanding is incomplete, but PFOA contamination in New York, New Hampshire, and Vermont appears to have been caused by a company that placed a non-stick coating on parts such as bearings and wires.

Section 5 – Landfills that Discharge Leachate (40 CFR 445)
Most landfill leachate will have some PFAS due to disposal of consumer products, but we are currently interested in landfills that have received PFAS laden industrial wastes such as sludge from metal finishers, leather tanneries and/or similar sources.

Section 6 – Centralized Waste Treaters (CWTs) (40 CFR 437)
CWTs accepting certain wastes may be sources of PFAS depending on the types of wastewater they receive for treatment.

Section 7 – Sites with soil or groundwater contamination including those where aqueous film forming foam (AFFF) was used
If your industry or facility has soil or groundwater contamination due to releases of industrial wastes or the use of AFFF (Class B) firefighting foam for fire suppression or firefighter training that discharges or infiltrates into the sanitary sewers may be a concern.

Section 8: Transportation Equipment Cleaning Facilities (Tankwash – 40 CFR 442)
Transportation tank cleaning facilities may discharge various PFAS in wastewater generated from cleaning/removing residues of chemicals that are hauled in the tanks.

Section 9: Industrial and Commercial Laundries
Industrial and commercial laundry facilities may discharge various PFAS in wastewater generated from cleaning/removing chemical residues on water or grease resistant treated linens, textiles, clothing, and shop towels, etc.

Section 10 – Industries using PFAS in other processes and operations
If you are aware of the use of chemicals containing PFAS in your processes or operations, please answer the questions below.
