Baseline
Sampling­
January
2003
An
initial
baseline
assessment
for
the
presence
of
PFOA
(
C­
8)
in
groundwater
and
wastewater/
surface
water
at
the
DuPont
Fayetteville
Works
was
conducted
in
January
2003.
Because
the
PFOA
production
facilities
at
Fayetteville
Works
were
brought
online
in
fall
2002
on
a
batch
test
basis
only,
the
assumption
going
into
this
assessment
was
that
little
APFO
should
be
detected
in
aqueous
media.
Based
on
this,
the
baseline
sampling
effort
was
focused
on
locations
where
PFOA
would
likely
be
readily
found
if
it
was
being
released
to
air/
water.
These
locations
included:

 
Shallow
groundwater
near
the
APFO
production
facility,
and
across
the
site
 
Wastewater/
surface
water
being
emitted
from
the
production
facility
On
January
27,
2003,
groundwater
and
wastewater/
surface
water
samples
were
collected
from
5
locations
at
the
Fayetteville
Works.
This
sampling
effort
is
documented
in
the
following

Work
Plan
for
Future
Monitoring
The
five
locations
sampled
at
Fayetteville
Works
in
January
2003
were
identified
as
follows:

 
SMW­
01
 
SMW­
02
 
NAF­
01
 
MW­
1S
 
Outfall­
002
(
Combined
wastewater
discharge
and
surface
water)

The
top
four
sample
designations
on
this
list
are
shallow
monitoring
wells
(
i.
e.,
first
groundwater
encountered).
Two
of
the
wells
(
i.
e.,
SMW­
01,
SMW­
02)
were
installed
in
January
2003
and
were
located
based
on
proximity
to
APFO
production
and
air
emission
modeling
results.
As
noted
above,
Outfall­
002
is
a
sampling
point
that
was
established
in
the
surface
water
stream
approximately
10
feet
from
the
discharge
pipe.

Future
monitoring
to
assess
the
presence
of
PFOA
will
be
conducted
through
yearly
sampling
at
the
same
monitoring
points.
