Summary
This
memorandum
contains
a
drinking
water
assessment
for
napropamide
for
terrestrial
uses.
This
assessment
incorporates
environmental
fate
data
and
transport
data
as
inputs
into
Tier
I
and
II
models
to
predict
drinking
water
exposure
for
10
of
the
registered
crops.

Human
exposure
to
napropamide
through
ingestion
of
drinking
water
from
the
use
on
many
small­
acreage
crops
was
assessed
through
modeling.
Surface
water
concentrations
from
use
on
terrestrial
crops
were
estimated
using
the
Tier
II
model
PRZM
version
3.12/
EXAMS
version
2.98.04
and
ground
water
concentrations
were
estimated
using
the
Tier
I
model
SCIGROW
version
2.2.
A
total
of
10
scenarios
were
modeled
for
napropamide
use
on
terrestrial
crops
based
on
individual
EFED
standard
scenarios.
The
scenarios
modeled
may
be
seen
in
Tables
1
and
2,
and
represent
the
highest
use
rates,
number
of
applications,
and
most­
vulnerable
sites
for
runoff
to
surface
water.
Some
uses
without
a
scenario
were
not
modeled.
These
scenarios
were
chosen
to
estimate
the
concentration
of
napropamide
in
surface
drinking
water
over
a
geographically
dispersed
range
of
existing
terrestrial
crop
production
areas
and
different
crop
types
(
orchards,
vineyards,
and
row
crops).
These
scenarios
chosen
for
this
assessment
represent
most
relevant
PRZM/
EXAMS
scenarios
for
the
terrestrial
use
of
napropamide.
Napropamide
is
to
be
applied
by
ground
equipment
only
as
per
the
use
information
provided
by
BEAD.
Appendix
A
provides
the
model
outputs
for
PRZM­
EXAMS.
Additional
details
on
each
scenario
may
be
seen
at
the
website:
http://
www.
epa.
gov/
oppefed1/
models/
water
.

Based
on
modeling
results,
the
estimated
surface
water
drinking
water
concentrations
for
napropamide
are:

112.0
m
g
/
L
for
the
1
in
10
year
annual
peak
concentration
(
acute)
0.5
m
g
/
L
for
the
1
in
10
year
annual
mean
concentration
(
non­
cancer
chronic)
and
0.2
m
g
/
L
for
the
36
year
annual
mean
concentration
(
cancer
chronic).

These
1
in
10
year
annual
peak
(
acute),
1
in
10
year
annual
mean
(
non­
cancer
chronic),
and
36­
year
annual
mean
concentrations
(
cancer
chronic)
were
derived
from
modeling
napropamide
on
the
labeled
terrestrial
crops
in
Table
1.
The
estimates
of
surface
water
concentrations
ranged
from
9.1
to
112.0,
0.05
to
0.5,
and
0.04
to
0.3
ug/
L
for
the
peak,
annual
mean,
and
overall
means,
respectively.
These
concentrations
will
likely
be
lower
because
any
napropamide
residues
on
the
soil
surface
may
degrade
faster
than
the
aerobic
soil
metabolism
rate.
However,
this
reduction
in
aqueous
concentrations
cannot
be
quantified
for
two
reasons.
There
are
uncertainties
regarding
the
amount
of
residues
left
on
the
surface
after
incorporation,
and
the
factors
affecting
photolysis
in
the
field
are
highly
variable.
For
shallow
ground
water
used
for
drinking
water,
the
SCI­
GROW
model
estimates
are
not
expected
to
exceed
4.5
:
g/
L
.
These
modeled
concentrations
can
be
considered
as
both
the
acute
and
chronic
value.
Since
no
degradates
of
concern
have
been
identified,
no
degradates
of
napropamide
were
modeled
in
this
assessment.
Should
the
Health
Effects
Division
(
HED)
determine
that
any
of
the
environmental
fate
degradates
are
of
concern,
a
separate
assessment
will
be
conducted
as
an
addendum
to
this
document.

For
most
compounds,
modeled
concentrations
in
surface
water
and
ground
water
are
generally
higher
than
monitored
concentrations.
Napropamide
was
not
detected
in
USGS
surface
water
monitoring
as
of
2001.

MODELING
ASSESSMENT
To
estimate
concentrations
of
napropamide
in
surface
water
or
groundwater,
modeling
was
used
and
compared
to
surface
water
or
groundwater
monitoring
data.
Typically,
Tier
I
drinking
water
assessments
(
FIRST)
are
completed
for
terrestrial
uses
by
EFED
for
chemicals
without
higher
tier
scenarios
or
as
a
screening
level
assessment.
In
the
case
of
napropamide,
Tier
II
scenarios
were
used
for
18
of
the
labeled
terrestrial
uses
for
napropamide.
Of
these
18
scenarios,
10
were
chosen
to
estimate
the
concentration
of
napropamide
in
surface
drinking
water
over
a
geographically
dispersed
range
of
existing
terrestrial
crop
production
areas
and
different
crop
types
(
orchards,
vineyards,
and
row
crops).
These
scenarios
chosen
for
this
assessment
represent
most
relevant
PRZM/
EXAMS
scenarios
for
the
terrestrial
use
of
napropamide.
Therefore,
drinking
water
exposure
assessments
for
people
who
drink
surface
water
were
completed
using
Tier
II
model
predictions.

The
modeled

may
be
seen
in
Tables
1
and
2.
Some
uses
without
a
scenario
were
not
modeled
and
some
uses
with
scenarios
were
represented
with
other
scenarios
in
th
same
geographic
region.

and
the
uncertainties
associated
with
them
see
R.
D.
Jones
et
al
(
March
21,
2000).
For
the
five
scenarios,
a
PCA
adjustment
of
0.87
was
applied
to
the
model.
A
PCA
of
0.87
is
the
default
value.
The

a

model
developed
using
data
from

submitted
to

in

SCI­

provides
a
high­

estimate
of
ground

concentrations
of
pesticides
on
soils
that
are
known
to
be
vulnerable
to
pesticide
leaching
(
i.
e.
high
sand
content
with
shallow
depth
to
groundwater).

Tables
3
and
4
provide
the
environmental
fate
inputs
and
ground
water
concentration
for
parent
napropamide,
respectively.
The
estimated
EEC
is
considered
representative
of
both
a
peak
and
longterm
average
concentration
because
of
the
inherent
transport
nature
of
ground
water
(
i.
e.
generally
slow
movement
from
source
of
contamination
both
laterally
and
horizontally).
Based
on
SCI­
GROW
modeling,
the
acute
and
chronic
napropamide
concentrations
are
not
expected
to
exceed
4.5
:
g/
L.
However,
the
USGS
has
not
found
any
detections
in
ground
water
as
of
2001.

APPENDIX

SCI­
GROW
Input
Table

Runs
for
Napropamide
for
Assessed
Terrestrial
Crops
Assumptions
SCIGROW
is
a
regression­
based
model
that
uses
few
input
parameters:
pesticide's
organic
carbon
partition
coefficient
(
Koc),
aerobic
soil
degradation
half­
life,
and
product
label
application
rate
and
frequency
(
Barrett,
1997).
It
provides
a
groundwater
screening
concentration
to
be
used
in
determining
the
potential
risk
to
human
health
from
drinking
water
contaminated
with
a
pesticide.
The
groundwater
concentration
is
estimated
based
on
the
maximum
application
rates
in
areas
where
groundwater
is
exceptionally
vulnerable
to
contamination.
These
vulnerable
areas
are
characterized
by
high
rainfall,
rapidly
permeable
soil,
and
shallow
aquifer.
Since
the
concentrations
estimated
from
this
model
are
likely
to
be
approached
in
only
a
very
small
percentage
of
drinking
water
sources,
SCIGROW
is
apparently
not
to
be
applied
for
national
or
regional
estimates.
Tables
1
and
2
present
the
Inputs
and
Outputs
for
the
SCI­
GROW
Model,
respectively.
