This
memorandum
provides
the
drinking
water
concentrations
for
the
trifluralin's
Tolerance
Reassessment
Eligibility
Decision
(
TRED).
Trifluralin
is
a
soil
incorporated
herbicide
registered
for
use
on
a
wide
range
of
food
crops
as
well
as
for
some
non­
food
crop
uses
such
as
turf
and
ornamentals
(
refer
to
the
use
closure
memo,
dated
February
12,
2003
for
the
details
on
the
uses
of
trifluralin).

The
drinking
water
assessment
is
based
on
modeling
and
monitoring
data.
Modeling
was
performed
for
parent
as
well
as
combined
triflualin
residues
[
i.
e.,
trifluralin
and
its
major
environmental
degradation
products
(>
10%
of
applied)]
from
fate
studies.
Major
degradation
products
include
(
5­
trifluoromethyl­
3­
nitro­
1,2­
benzene
diamine,
TR­
6),
(
2­
ethyl­
7­
nitro­
5­
trifluoromethyl
benzimidazole,
TR­
15),
and
the
   ­
trifluoro­
5­
nitro­
N4,
N4­
dipropyl
toluene­
3,4,
diamine,
TR­
4.
Degradation
products
were
considered
in
the
assessment
to
account
for
potential
identification
of
degradation
products
of
toxicological
concern
by
the
Health
Effects
Division
(

FIRST
Modeling
(
Tier
I)

Tier
I
FIRST
modeling
was
conducted
using
application
rates
for
sugar
cane
(
4.0
lbs
ai/
A).
This
application
rate
was
selected
because
it
is
the
highest
application
rate
for
all
trifluralin
uses.
The
daily
peak
concentration
of
trifluralin
is
not
likely
to
exceed
66.9
ppb.
The
annual
average
concentration
of
trifluralin
is
not
likely
to
exceed
6.6
ppb.
For
combined
trifluralin
residues
(
parent
and
degradation
products),
the
peak
daily
and
annual
average
concentrations
are
not
likely
to
exceed
72.5
and
17.6
ppb,
respectively.

PRZM/
EXAMS
Modeling
(
Tier
II
)

Since
trifluralin
is
registered
on
several
crops,
Tier
II
modeling
crop
scenarios
were
selected
to
reflect
crops
with
the
highest
uses
of
trifluralin
(
e.
g.
soybeans,
cotton),
the
maximum
application
rate
(
e.
g.,
sugarcane),
and
availability
of
scenarios.
GIS
analysis
indicates
the
selected
scenarios
generally
represent
moderate
to
high
trifluralin
use
area
(
i.
e.,

11
lbs
ai/
mi2)(
Figure

Among
the
crops
modeled
(
soybeans,
cotton,
canola,
tomatoes,
wheat,
carrots,
cabbage,
sugarcane,
turf
and
ornamentals),
the
maximum
environmental
concentrations
were
obtained
for
sugarcane
applied
as
a
single
aerial
application
at
4.0
lbs
ai/
acre.
Trifluralin
is
a
volatile
pesticide
(
Henry
Constant
=
1.62E­
4
atm
m3/
mole
and
vapor
pressure=
1.10E­
4
Torr).
It
has
been
detected
in
both
rain
and
air
samples
in
environmental
monitoring
programs
(
Coupe
et
al.
2003,
Rice
et
al
2003).
Modeling
of
volatilization
rates
from
soil,
as
modeled
by
PRZM,
were
assumed
to
be
captured
through
the
aerobic
soil
metabolism
half­
life.
In
the
reservoir,
volatilization
was
simulated
using
the
Henry's
Constant
and
vapor
pressure.

For
the
sugarcane
use,
the
1
in
10
year
daily
peak
concentration
of
trifluralin
is
not
likely
to
exceed
38.1
ppb.
The
1
in
10
year
annual
average
concentration
is
not
likely
to
exceed
1.9
ppb.
The
30
year
annual
average
concentration
is
not
likely
to
exceed
1.3
ppb.
For
combined
trifluralin
residues,
the
concentration
is
not
likely
to
exceed
38.4
ppb
for
the
1
in
10
year
daily
peak
concentration,
2.0
ppb
for
the
1
in
10
year
annual
average
concentration,
and
1.4
ppb
for
the
30
year
annual
average
concentration.
Concentrations
from
Tier
II
model
simulation
are
presented
in
Table

Surface
Water
Monitoring
Data
Surface
water
monitoring
data
for
trifluralin
were
obtained
from
the
USGS
National
Water
Quality
Assessment
(
NAWQA)
data
(
http://
water.
usgs.
gov/
nawqa/
data)
and
USGS/
EPA
pilot
reservoir
monitoring
program
data
(
Blomquist,
et
al.
2001).

Surface
water
monitoring
data
were
analyzed
by
location
(
sampling
station)
and
year
of
sampling.
Data
analysis
included
identification
of
NAWQA
sampling
stations
with
trifluralin
detections,
determination
of
peak
concentration
of
trifluralin,
and
calculation
of
time
weighted
annual
means
(
TWAM).
The
minimum
criteria
for
calculating
TWAM
concentration
at
a
sampling
station
in
a
given
year
was
a
single
detection
of
trifluralin.
Non­
detections
were
assumed
to
be
equivalent
to
the
minimum
detection
limit
(
MDL).
This
data
handling
approach
was
taken
because
of
the
highly
censored
data
(
low
detection
frequencies)
for
trifluralin.
The
equation
used
for
calculating
the
time

annual
mean
is
as
follows:

Trifluralin
was
analyzed
in
water
samples
using
USGS
analytical
schedule
2001
(
Zaugg,
et
al.
1995).
The
method
uses
a
solid
phase
extraction
on
C­
18
column
coupled
with
chemical
analysis
using
GC/
MS
with
single
ion
mode
for
selective
confirmation
and
quantification
of
pesticides.
Trifluralin
has
a
peak
retention
time
of
21.354
minutes.
Recoveries
of
trifluralin
were
determined
in
surface
water
(
South
Platte
River
near
Henderson,
CO),
ground
water
(
Jefferson
County,
CO
near
Denver
Federal
Center),
and
reagent­
water.
Method
detection
limit
(
MDL)
is
defined
as
the
minimum
concentration
with
99
percent
confidence
the
measured
concentration
is
greater
than
zero.
Seven
replicate
samples
at
0.1
ug/
L
were
used
to
establish
a
preliminary
MDL.
The
MDL
for
trifluralin
was
0.002
ug/
L
(
59%
of
recovery)
in
reagent
water.
The
percent
recovery
of
trifluralin
at
0.1
to
1
µ
g/
g
ranged
from
63%
to
64%
in
surface
water
and
44%
to
54%
in
ground
water.

Monitoring
Data
Trifluarlin
was
detected
in
the
USGS/
EPA
pilot
reservoir
monitoring
study
at
the
CA,
PA,
LA,
and
SD
reservoirs
(
Blomquist,
et
al.
2001).
Detection
frequencies
of
trifluralin
were
low
in
both
intake
(
2.8%)
and
treated
(
2.2%)
water.
A
maximum
of
two
detections,
designated
as
estimates
`
E',
were
found
in
the
intake
water
samples
at
the
PA
reservoir
in
2000
and
the
LA
reservoir
in
1999.
Estimated
concentrations
are
defined
as
concentrations
below
the
method
detection
limit
(
MDL).
Estimated
trifluralin
concentrations
in
both
intake
and

samples
were
comparable
to
the
MDL
(

Modeling
SCI­
GROW
modeling
was
performed
for
sugarcane
because
it
represents
the
highest
application
rate
(
4.0
lbs
ai/
acre).
The
estimated
shallow
ground
water
concentration
for
trifluralin
and
trifluralin
residues
is
not
likely
to
exceed
0.035
µ
g/
L.
Predicted
concentrations
of
trifluralin
and
combined
trifluralin
residues
in
ground
water
are
the
same
because
major
degradation
products
of
trifluralin
were
formed
through
degradation
processes
(
e.
g.,
photodegradation).
Photodegradation
is
not
considered
in
the
SCI­
GROW
model.

Ground

Ground
water
monitoring

for
trifluralin
were
obtained
from
the
USGS

GIS
Characterization
of
Trifluralin
Surface
and
Ground
Water
Monitoring
Data
A
GIS
analysis
indicates
trifluralin
use
is
widespread
across
the
United
States
(
Figure
2)
The
highest
trifluralin
use
areas
(
51
to
175
lbs
of
trifluralin/
mile2)
are
found
in
the
Mississippi
Embayment,
Red
River
Basin,
Northwestern
Iowa,
Southwestern
Minnesota,
and
Western
Panhandle
of
Texas.
Moderate
trifluralin
use
(
11­
50
trifluralin/
mile2))
can
be
found
in
most
of
mid­
western
corn
belt,
Great
Plains,
and
the
Central
Valley
of
California,
Coastal
Plains
of
North
Carolina
and
Georgia,
and
the
Mississippi
Embayment.

NAWQA
surface
and
ground
water
sampling
stations
are
located
in
the
moderate
to
high
trifluralin
use
regions
(
Figure
3
and

In
these
regions,
the
maximum
trifluralin
concentrations
were
greater
than
<
0.02
ug/
L
(
Figure

There
are
few

associated
within
areas
of
moderate

Comparison
of
Predicted
Trifluralin
Concentrations
and
Monitoring
Data
The
maximum
daily
peak
concentration
of
trifluralin
from
PRZM/
EXAMS
simulation
(
38.1
ppb)
is
greater
than
the
highest
concentration
in
the
USGS/
NAWQA
monitoring
database
(
1.74
ppb).
However,
the
maximum
annual
average
trifluralin
concentration
in
surface
water
(
1.9
ppb)
is
comparable
to
TWAM
concentrations
in
USGS
monitoring
studies
(
0.618
ppb).
Additionally,
the
maximum
trifluralin
concentration
in
shallow
ground
water
(
0.035
ppb),
as
predicted
through
SCI­
GROW,
is
lower
than
concentrations
in
the
NAWQA
ground
water
monitoring
database
(
0.150
ppb).

Uncertainties,
Limitations,
and
Assumptions
°
There
are
no
aerobic
aquatic
degradation
data
for
trifluralin.
A
default
aerobic
aquatic
degradation
half­
life
was
calculated
as
twice
the
aerobic
soil
metabolism
half­
life.
Submission
of
aerobic
aquatic
metabolism
data
is
expected
reduce
uncertainties
in
the
aquatic
metabolism
of
trifluralin.

°
Volatilization
of
trifluralin
was
not
directly
modeled
in
the
PRZM
scenario.
Because
the
aerobic
soil
metabolism
half­
life
represents
both
degradation
and
volatilization,
the
aerobic
soil
metabolism
half­
life
was
used
to
jointly
describe
degradation
and
volatilization
processes.

°
Cumulative
trifluralin
residue
modeling
accounted
for
only
major
degradation
products
(>
10%
of
the
applied
radioactivity)
identified
in
fate
studies.
The
major
degradation
products
were
identified
only
in
aqueous
photolysis
and
in
anaerobic
soil
metabolism.
There
were
several
degradation
products
identified
in
aerobic
soil
metabolism,
but
none
of
these
are
classified
as
major
degradation
products.
The
uncertainty
in
the
predicted
EECs
arises
from
not
including
the
minor
degradation
products
(<
10%
of
applied
radioactivity)
in
the
drinking
water
exposure
assessment.

°
There
may
be
uncertainty
in
the
predicted
EECs
due
to
the
application
timing
used
for
modeling.
The
label,
CORNBELT,
allows
for
spring
and
fall
applications.
Model
simulations
are
based
a
fixed
application
date
of
March
1st.
EECs
are
expected
to
vary
according
to
the
date
of
application.

°
Modeling
was
conducted
using
the
maximum
application
rate
for
specific
crops.
The
use
of
typical
application
rates
on
specific
crops
is
expected
to
lower
predicted
concentrations.
15
°
Tier
II
EECs
were
adjusted
for
percent
cropped
area
(
PCA)
in
the
watershed.
For
all
the
crops
modeled
except
soybeans,
cotton
and
wheat,
a
default
percent
cropped
area
factor
of
0.87
was
used.
The
crop
specific
PCA
factors
were
available
for
soybeans
(
0.46),
cotton
(
0.2)
and
wheat
(
0.56).
If
specific
PCA
factors
for
other
crops,
such
as
canola,
tomatoes,
carrots,
cabbage,
sugarcane,
turf,
and
ornamentals
were
available,
it
is
likely
to
lower
the
predicted
EECs.

°
Trifluralin
degradation
products
are
not
analytes
on
the
USGS
analytical
methods.
Therefore,
no
monitoring
data
for
trifluralin
degradation
products
are
available
to
allow
for
a
comparison
of
predicted
concentrations
and
actual
concentrations
of
combined
trifluralin
residues.

°
Although
the
NAWQA
monitoring
stations
appear
to
be
located
(
based
on
county
level
data)
in
most
of
the
high
trifluralin
use
areas,
the
study
design
of
NAWQA
was
not
targeted
to
account
for
all
trifluralin
use
areas,
timing
of
application
and
other
factors
which
may
more
accurately
represent
spatially
and
temporally
dependent
variables
influencing
runoff
vulnerability.

Advisory
Values
Based
on
the
2002
drinking

standards
and
health
advisories
(
HA),
no

is
available
for
trifluralin.
The
one

advisories
for
10

child
are
80
ppb.
The
Lifetime
HA
is
reported
as

Lifetime
HA
is
the
concentration
of
a
chemical
in
drinking
water
that
is
not
expected
to
cause
any
adverse
non­
carconigenic
effects
for
a

The
lifetime

is
based
on
exposure
of
a
