PFAS
the United Kingdom with initial results
pending in the coming months.
The longest running in situ CAC
treatment for PFAS has maintained
greater than 99.5 percent removal to
detection levels for five years thus far.
However, based on an independent,
peer-reviewed model completed for
the project, the treatment should remain
effective for 50 years. This treatment
was 17 times less expensive in a costcomparison
analysis than implementing
an ex situ P&T approach, based on a very
conservative CAC treatment longevity
of 20 years.
In total, more than one hundred
CAC treatments for PFAS projects are
currently in the implementation or
planning stages. All field installations
applied thus far are meeting performance
expectations. In a commitment to
ensure the remedial approach meets
objectives, performance warranties for
CAC PRBs may be considered. 
MOUNTING PUBLIC CONCERN
OVER PFAS LEADS TO EPA
REGULATION
Public concern over PFAS has continued to increase with many PFAS-focused citizen action
groups (CAGs) forming and collaborating. One of these collaborations, the National PFAS
Contamination Coalition (NPCC), is an aggregate of more than 20 local PFAS CAGs across
the U.S. Among their priorities outlined in a 22-point action plan, the NPCC is pushing
Congress to create a one part per trillion (ppt) maximum contaminant level (MCL) for the
entire PFAS chemical class.
Erin Brockovich has encouraged the CAG mobilization efforts, profiling PFAS at length
and guiding her readers to organize and hold local water utilities accountable in her
latest (2020) book, Superman's Not Coming: Our National Water Crisis and What We
the People Can Do About It. A year prior, Robert Billot's best-selling book Exposure and
the accompanying major motion picture, Dark Waters, were released to critical acclaim,
detailing a personal account of his class action litigation against Dupont, who used the
chemicals to produce Teflon®.
With a new Administration and growing Congressional support, these calls to action are
now being received. On Jan. 29, 2021, the PFAS Task Force, a 132-member bipartisan
Congressional delegation, submitted a letter to President Biden urging his administration
to immediately act on the " growing PFAS pollution crisis. " Included in their demands was
to direct EPA to designate two types of PFAS, perfluorooctanesulfonic acid (PFOS) and
perfluorooctanoic acid (PFOA), as " hazardous substances " under CERCLA, and clean up
legacy PFAS pollution. On Feb. 22, the EPA moved a step closer toward satisfying these
demands, making final determinations to regulate PFOS and PFOA. President Biden's
pick to lead the EPA, Michael Regan, was confirmed in March 2021 and is anticipated to
keep the pressure on the process to establish MCLs, having ordered one of the nation's
first regulatory cleanups of PFAS as Secretary of the North Carolina Department of
Environmental Quality (NCDEQ).

Total PFOA and PFOS in
groundwater at FAI pilot test well
MW-1903-20. PFOA and PFOS have
been remediated to detection
limits of less than 2 ng/L for the
two post-application events.
REGENESIS
Average total PFAS in monitoring well pairs upgradient and
downgradient of CAC PRB at Camp Grayling, Michigan. The
two nearest downgradient well pairs were installed prior to
application. Two additional well pairs were installed after six
months. Total PFAS concentrations remain below detection in
all well pairs relative to an average upgradient concentration
of greater than 100 ng/L.
