Conclusions:

In
response
to

request
(Carol

the
three
major
linuron
metabolites
*
formed

use
on
carrots

are
represented
by
this
memorandum.
The
degradate
3,4­
dichloroaniline
(3,4­
DCA)
was
not
included
in
this
assessment.
Based
on
the
results
from
the
aerobic
soil
metabolism
study
(MRID#
41625401),
the
degradate
3,4­
DCA
was
not
detected
(0.01
ppm
detection
limit).
According
to
acceptable
fate
studies,
3,4­
DCA
is
formed
under
anaerobic
aquatic
conditions
(conditions
rarely
found
in
the
environment
and/
or
relevant
to

assessment)
consisted
of
1.5%
of
the
applied
linuron.

Environmental
Fate
and
Transport
Assessment
Although
the
environmental
fate
data
base
for
parent
linuron
is
essentially
complete,
two
environmental
fate
data
requirements
(leaching/
adsorption/
desorption
and
terrestrial
field
dissipation
studies)
are
not
fulfilled.
The
environmental
fate
assessment
for
linuron
is
incomplete
and
tentative
because
information
on
the
persistence,
mobility
and
dissipation
pathways
of
several
degradates
of
linuron
is
not
available.

Parent
linuron
appears
to
be
moderately
persistent
and
relatively
immobile.
Increased
mobility
may
occur
under
specific
environmental
conditions
such
as
in
coarse
textured
soils
and
soils
with
low
levels
of
organic
matter.
Linuron
dissipates
principally
by
biotic
processes
such
as
microbial
degradation.
In
surface
soils
with
adequate
organic
matter,
the
combined
processes
of
adsorption
and
microbial
degradation
would
limit
linuron's
potential
to
migrate
to
ground
water.
Linuron
could
runoff
to
surface
water
bodies.
In
that
case,
it
would
degrade
fairly
rapidly
to
three
primary
metabolites
(desmethoxy
linuron,
desmethyl
linuron,
norlinuron,
and
3,4­
DCA,
none
of
each
is
>10%
of
the
applied
linuron
in
the
aerobic
soil
metabolism
study).
However,
information
on
the
persistence
and
mobility
of
these
degradates
is
not
currently
available.

Linuron
exhibits
some
of
the
properties
and
characteristics
of
chemicals
that
have
been
detected
in
ground
water,
and
linuron
itself
has
been
detected
in
ground
water
in
four
states
(Georgia,
Missouri,
Virginia
and
Wisconsin).
Linuron
is
moderately
persistent
with
an
aerobic
soil
metabolism
half­
life
ranging
from
57
to
100
days.
Because
linuron
is
sufficiently
persistent
and
may
be
mobile
under
certain
environmental
conditions,
it
has
the
potential
to
impact
ground
water
quality.

Linuron
can
be
applied
aerially
or
by
ground
spray
and
therefore
could
contaminate
surface
waters
through
spray
drift.
It
has
the
potential
to
be
somewhat
persistent
in
surface
waters,
particularly
those
with
low
microbiological
activity
and
long
hydrological
residence
times.
In
a
lab
study,
linuron
degraded
with
a
half­
life
of
less
than
3
weeks
in
nonsterile
anaerobic
silt
loam
and
sand
soil:
water
(1:
1)
systems.
It
may
be
less
persistent
in
water
and
sediment
under
anaerobic
conditions
than
under
aerobic
conditions.
Its
bioconcentration
potential
is
relatively
low.

Linuron
is
not
currently
regulated
under
the
Safe
Drinking
Water
Act,
and
water
supply
systems
are
not
required
to
sample
4
and
analyze
for
it.
The
primary
treatment
processes
employed
by
most
water
systems
may
not
always
be
completely
effective
in
removing
linuron's
degradates.
As
a
result,
the
Agency
does
have
some
moderate
concerns
regarding
potential
risks
of
these
degradates
to
surface
water
source
supply
systems.

Surface
Water
Monitoring
The
EFED
currently
has
no
monitoring
data
on
the
concentrations
of
desmethyl
linuron,
desmethoxy
linuron
or
nor
linuron
in
surface
water.

Modeling
Tier
II
surface
water
modeling
was
done
using
the
Index
Reservoir
(IR)
scenario
and
Percent
Crop
Area
(PCA)
factor
applied
after
modeling.

The
index
reservoir
represents
a
potentially
vulnerable
drinking
water
source
based
on
the
geometry
of
an
actual
reservoir
and
its
watershed
in
a
specific
area
(Illinois),
using
regional
screening
specific
cropping
patterns,
weather,
soils,
and
other
factors.

The
PCA
is
a
generic
watershed­
based
adjustment
factor
which
represents
the
portion
of
a
watershed
planted
to
a
crop
or
crops
and
will
be
applied
to
pesticide
concentrations
estimated
for
the
surface
water
component
of
the
drinking
water
exposure
assessment
using
PRZM/
EXAMS
with
the
index
reservoir
scenario.

EFED
has
limited
fate
and
mobility
data
on
these
metabolites;
thus,
a
combined
residue
approach
was
used
to
calculate
their
aerobic
soil
metabolism
half­
lives
(assuming
equal
toxicity)
by
the
summation
of
the
concentrations
of
the
parent
and
its
metabolites.

6
Assumptions
and
Uncertainties
11,12
In
general,
the
use
of
input
parameter
values
for
the
parent
may
increase
the
uncertainties
in
this
assessment.

Index
Reservoir
The
Index
reservoir
represent
potential
drinking
water
exposure
from
a
specific
area
(Illinois)
with
specific
cropping
patterns,
weather,
soils,
and
other
factors.
Use
of
the
index
reservoir
for
areas
with
different
climates,
crops,
pesticides
used,
sources
of
water
(e.
g.
rivers
instead
of
reservoirs,
etc),
and
hydrogeology
creates
uncertainties.
In
general,
because
the
index
reservoir
represents
a
fairly
vulnerable
watershed,
the
exposure
estimated
with
the
index
reservoir
will
likely
be
higher
than
the
actual
exposure
for
most
drinking
water
sources.
However,
the
index
reservoir
is
not
a
worst
case
scenario,
communities
that
derive
their
drinking
water
from
smaller
bodies
of
water
with
minimal
outflow,
or
with
more
runoff
prone
soils
would
likely
get
higher
drinking
water
exposure
than
estimated
using
the
index
reservoir.
Areas
with
a
more
humid
climate
that
use
a
similar
reservoir
and
cropping
patterns
may
also
get
more
pesticides
in
their
drinking
water
than
predicted
using
this
scenario.

PRZM/
EXAMS
uses
the
characteristics
of
a
single
soil
to
represent
the
soil
in
the
basin.
In
fact,
soils
can
vary
substantially
across
even
small
areas,
and
this
variation
is
not
reflected
in
these
simulations.

PRZM/
EXAMS
does
not
consider
tile
drainage.
Areas
that
are
prone
to
substantial
runoff
are
often
tile
drained.
Tile
drainage
contributes
additional
water
and
in
some
cases,
additional
pesticide
loading
to
the
reservoir.
This
may
cause
either
an
increase
or
decrease
in
the
pesticide
concentration
in
the
reservoir.
Tile
drainage
also
causes
the
surface
soil
to
dry
out
faster.
This
will
reduce
runoff
of
the
pesticide
into
the
reservoir.
The
watershed
used
as
the
model
for
the
index
reservoir
(Shipman
City
Lake)
does
not
have
tile
drainage
in
the
cropped
areas.

EXAMS
is
unable
to
easily
model
spring
and
fall
turnover.
Turnover
occurs
when
the
temperature
drops
in
the
fall
and
the
thermal
stratification
of
the
reservoir
is
removed.
Turnover
occurs
again
in
the
spring
when
the
reservoir
warms
up.
This
results
in
complete
mixing
of
the
chemical
through
the
water
column
at
these
times.
Because
of
this
inability,
the
Index
Reservoir
has
been
simulated
without
stratification.
There
is
7
data
to
suggest
that
Shipman
City
Lake,
upon
which
the
Index
Reservoir
is
based,
does
indeed
stratify
in
the
deepest
parts
of
the
lake
at
least
in
some
years.
This
may
result
in
over
or
underestimation
of
the
concentration
in
drinking
water
depending
upon
the
time
of
the
year
and
the
depth
the
drinking
water
intake
is
drawing
from.

Percent
Crop
Area
Correction
Factor
The
PCA
is
a
watershed­
based
modification.
Implicit
in
its
application
is
the
assumption
that
currently­
used
field­
scale
models
reflect
basin­
scale
processes
consistently
for
all
pesticides
and
uses.
In
other
words,
we
assume
the
field
scale
processes
simulated
by
the
coupled
PRZM
and
EXAMS
models
are
a
reasonable
approximation
of
pesticide
fate
and
transport
within
a
watershed
that
contains
a
drinking
water
reservoir.
If
the
models
fail
to
capture
pertinent
basin­
scale
fate
and
transport
processes
consistently
for
all
pesticides
and
all
uses,
the
application
of
a
factor
that
reduces
the
estimated
concentrations
predicted
by
modeling
could,
in
some
instances,
result
in
inadvertently
passing
a
chemical
through
the
screen
that
may
actually
pose
a
risk.
Some
preliminary
assessments
made
in
the
development
of
the
PCA
suggest
that
PRZM/
EXAMS
may
not
be
realistically
capturing
basin­
scale
processes
for
all
pesticides
or
for
all
uses.
A
preliminary
survey
of
water
assessments
which
compared
screening
model
estimates
to
readily
available
monitoring
data
suggest
uneven
model
results.
In
some
instances,
the
screening
model
estimates
are
more
than
an
order
of
magnitude
greater
than
the
highest
concentrations
reported
in
available
monitoring
data;
in
other
instances,
the
model
estimates
are
less
than
monitoring
concentrations.
Because
of
these
concerns,
the
Science
Advisory
Panel
(SAP)
recommended
using
the
PCA
only
for
"major"
crops
in
the
Midwest.
For
other
crops,
development
of
PCA's
will
depend
on
the
availability
of
relevant
monitoring
data
that
could
be
used
to
evaluate
the
result
of
the
PCA
adjustment.

The
spatial
data
used
for
the
PCA
came
from
readily­
available
sources
and
have
a
number
of
inherent
limitations:

n
=

may
not
provide
reasonable
estimates
of
actual
PCA's
for
smaller
watersheds.
The
watersheds
that
drain
into
drinking
water
reservoirs
are
generally
smaller
than
the
8­

HUC
and
may
be
better
represented
by
watersheds
defined
for

intakes.

The
PCA's
were
generated
using
data
from
the
1992
Census
of
Agriculture.
However,
recent
changes
in
the
agriculture
sector
from
farm
bill
legislation
may
significantly
impact
the
distribution
of
crops
throughout
the
country.
The
methods
described
in
this
report
can
rapidly
be
updated
as
more
current
agricultural
crops
data
are
obtained.
The
assumption
that
yearly
changes
in
cropping
patterns
will
cause
minimal
impact
needs
to
be
evaluated.

The
PCA
adjustment
is
only
applicable
to

applied

agricultural
crops.

agricultural
uses
are
not
included
in
the
screening
model
assessments
for
drinking
water.

The
PCA
does
not
consider
percent
crop
treated
because
detailed
pesticide
usage
data
are
extremely
limited
at
this
time.
Detailed
pesticide
usage
data
are
currently
available
for
only
a
few
states.

Groundwater
Monitoring
The
EFED
has
no
monitoring
data
on
the
concentrations
of
desmethyl
linuron,
desmethoxy
linuron
or
nor
linuron
in
groundwater
at
the
present
time.

There
is
a
possibility
that
those
metabolites
were
not
intended
to
look
for,
or
they
might
have
been
present
at
concentrations
lower
than
that
of
the
instruments
used
for
the
water
samples
collected
The
SCI­
GROW
model
was
used
to
estimate
potential
groundwater
concentrations
of
linuron.

Table
3
shows
the
input
parameter
values
used
in
SCI­
GROW
modeling.
