Per- and polyfluoroalkyl substances (PFAS)

PFAS Products

  • Teflon
  • Scotchguard
  • Stainmaster
  • Stainsafe
  • Silverstone
  • Polartec
  • Texapore
  • Gore-tec
  • PFAS were invented in the 1930s and were the main ingredients in

nonstick and waterproof coatings

  • More than 3,000 manmade chemicals are classified as PFAS. Most is

known about PFOS and PFOA

  • Compounds are persistent in the environment and mobile

Initial Regulatory Development

EPA was slow to regulate PFAS environmental impacts

  • Recognized in early 2000s for potential health and environmental

impacts

  • EPA published provisional health advisory (not a regulatory limit)
  • f 70 ppt for PFOA/PFOS in drinking water in 2009
  • Phased elimination of the manufacture of certain PFAS compounds

by 2015

  • Developed PFAS Action Plan in February 2019

States have been leading regulatory change

  • Requiring testing of discharges, surface and ground water to

determine extent of the problem

  • Some states eliminating inventory and disposal of PFAS foams

from fire departments

  • Establishing discharge limits and requiring PFAS site clean-ups

Progress on EPA’s PFAS action plan

(Released: February 14, 2019)

Drinking Water

  • February 20, 2020 released a preliminary determination to

regulate PFOS and PFOA under the Safe Drinking Water Act Cleanup

  • Initiated regulatory process to designate PFOA and PFOS

hazardous substances

  • Issued interim recommendations for groundwater

contamination on December 19, 2019 Toxics

  • February 20, 2020 added PFAS chemicals to the Toxics Release

Inventory and proposed regulations on importing PFAS chemicals used in surface coatings Monitoring

  • Added 6 PFAS compounds to monitoring by Public Waster

Systems Research

  • December 19, 2019 - Validated analytical methods for 29 PFAS

compounds

Congress Acted through the NDAA

(National Defense Authorization Act, December 2019) DOD Provisions include:

  • Phase out of AFFF foams by 2024
  • PFAS-containing waste must be stored according to RCRA
  • Controls over the incineration of PFAS waste
  • Requirements that drive identification and cleanup of contaminated

military installations

EPA Provisions Include:

  • Requirement to add PFAS compounds to Toxic Release Inventory (TRI)
  • Publish interim guidance on disposal and destruction by Dec. 2020
  • Expedite research into health and environmental effects and

remediation technology

  • TSCA amendments requiring reporting by PFAS manufacturers

What wasn't included was inclusion of a CERCLA hazardous substance designation for certain PFAS chemicals

AFFF firefighting foam

  • Disposal of the PFAS foam inventory from fire departments and DOD
  • Disposal of diluted firefighting foam wastewater from firefighting

activity

Soil and water contamination

  • US Department of Defense
  • Identified 425 military sites with high concentrations of soil and

groundwater PFAS contamination

  • Preliminary estimate of $2 billion in cleanup costs
  • Managing PFAS contaminated leachate from municipal landfills
  • Soil and groundwater from 100’s of contaminated sites

Other PFAS waste sources

  • Water treatment media with concentrated PFAS

Current Market Opportunities

Potential Treatment/Disposal Options

Technology Risks

  • Activated carbon
  • Ion exchange
  • Reverse osmosis

Treatment becomes more complicated when wastewater has high levels of organics.

  • Deepwell Injection

Deepwell disposal may be limited to lower concentrations due to foaming.

PFAS contaminated Water PFAS Soil

Technology Risks

  • Thermal desorption
  • Thermal soil burners
  • Commercial incineration

Air emissions are in early stages of evaluation and burner temperature and residence time are

  • parameters. Large resistance from activist groups.
  • Landfill

Leachate may require PFAS treatment.

US Ecology PFAS waste solutions

Arid Climate Landfill Disposal (Beatty, NV and Grand View, ID)

  • No leachate discharge
  • Capable of high concentration, large volume event projects

Other Landfill Solutions (Belleville, MI and Robstown, TX)

  • Accept lower concentration PFAS waste to manage leachate

treatment

Thermal Soil Treatment (Moose Creek, AK)

  • Only thermal treatment unit specifically permitted for PFAS
  • EPA Office of Research and Development involved in extensive testing
  • Adjacent to Eielson AFB with approx. 300,000 tons of PFAS soil

Deepwell Disposal (Winnie, TX)

  • Permitted to accept municipal landfill leachate
  • Caprock disposal facility can accept high levels of solids
