This
memo
provides
the
estimated
drinking
water
concentrations
from
surface
water
and
ground
water
sources
for
assisting
Health
and
Effects
Division
in
determining
the
potential
risk
to
human
health.
The
drinking
water
assessment
is
based
solely
on
model­
estimated
exposure
concentrations
in
surface
water
and
ground
water.

Flumetsulam
is
a
selective
herbicide
for
use
to
control
broadleaf
weeds
in
soybeans
and
field
corn.
It
belongs
to
the
triazolopyrimidine
chemical
family.
The
physical
chemical
properties
of
flumetsulam
are
included
as
Attachment
1.
The
mode
of
action
is
similar
to
the
sulfonylurea
herbicides,
which
are
ALS
(
Acetolactate
synthase)
inhibitors.
Flumetsulam
can
be
applied
alone,
such
as
in
Python
®
or
Broadstrike
®
,
or
applied
in
formulation
with
other
active
ingredients,
such
as
in
Hornet
®
(
flumetsulam
+
clopyralid),
Accent
Gold
®
(
flumetsulam
+
clopyralid
+
2
Nicosulfuron),
Broadstrike
+
Dual
®
(
flumetsulam
+
metolachlor),
Broadstrike
+
Treflan
®
(
flumetsulam
+
trifluralin)
and
others.
Since
only
flumetsulam
will
be
considered
in
this
drinking
water
assessment,
the
maximum
allowable
application
rate
for
flumetsulam
alone
of
0.07
lb
a.
i./
acre
will
be
used
to
simulate
corn
and
soybeans
uses
.
Both
aerial
and
ground
application
are
allowed
in
the
labels.
The
exposure
concentrations
of
drinking
water
were
estimated
for
aerial
applications,
as
drift
from
aerial
applications
result
in
higher
exposure
concentrations
in
surface
water
than
ground
applications.

The
estimated
drinking
water
concentrations
of
flumetsulam
in
surface
water
are
summarized
in
Table
1.
Among
EFED's
standard
crop
scenarios,
there
are
nine
scenarios
for
corn
and
only
one
for
soybeans.
The
Mississippi
corn
scenario
predicts
the
highest
1­
in­
10
year
peak
concentrations
of
2.03

g/
L,
whereas
the
North
Dakota
corn
scenario
gives
the
highest
1­
in­
10
annual
mean
of
0.59

g/
L,
and
overall
annual
mean
of
0.34

L.
Table
2
summarizes
the
estimated
drinking
water
concentrations
of
flumetsulam
in
ground
water.
Both
acute
and
chronic
estimates
are
0.823

Models,

Parameters
Used
Estimate
Concentrations
of
Flumetsulam
The
estimated
drinking
water
concentrations
from
surface
water
sources
were
calculated
using
Tier
II
PRZM
(
Pesticide
Root
Zone
Model)
and
EXAMS
(
Exposure
Analysis
Modeling
System).
PRZM
is
used
to
simulate
pesticide
transport
as
a
result
of
runoff
and
erosion
from
an
agricultural
field
and
EXAMS
estimates
environmental
fate
and
transport
of
pesticides
in
surface
water
and
using
the
linkage
program
shell
­
PE4v01
(
dated
08/
13/
2003),
which
incorporates
the
standard
scenarios
developed
by
EFED.

Linked
crop­
specific
scenarios
and
meteorological
data
were
used
to
estimate
exposure
as
a
result
of
uses
on
field
corn
and
soybeans.
Simulations
were
done
using
the
Index
Reservoir
scenario
in
EXAMS,
which
is
a
surrogate
for
a
drinking
water
source
drawn
from
surface
water.
Weather
and
agricultural
practices
are
simulated
over
30
years
so
that
the
1­
in10
year
exceedence
probability
at
the
site
can
be
estimated.
The
values
generated
by
the
models
for
drinking
water
were
multiplied
by
a
crop
area
factor
(
PCA),
which
accounts
for
the
fact
that
it
is
unlikely
for
any
basin
to
be
completely
planted
to
an
agricultural
crop.
The
maximum
PCA
for
corn
is
0.46
and
the
value
for
soybeans
is
0.41.

Concentrations
in
ground
water
were
estimated
using
the
Tier
I
SCI­
GROW
(
Screening
Concentration
In
Ground
Water)
model.

Nine
standard

one
for

were
simulated
for
this
drinking
water
assessment.
These
scenarios
are
briefly
identified
in
Table
