Site
Description
The
Lammers
Barrel
property
is
now
a
vacant
lot,
approximately
two
acres
in
size,
located
in
Beavercreek,
Ohio.
The
property
is
bisected
by
Little
Beaver
Creek
which
flows
west
to
east
through
the
site.
The
property
is
bordered
to
the
west
and
south
by
Grange
Hall
Road
and
East
Patterson
Road,
respectively.
An
abandoned
railroad
right
of
way
makes
up
the
northern
border.
The
facility
experienced
a
fire
in
1969,
that
completely
destroyed
the
buildings.
The
only
structures
remaining
are
a
concrete
pad,
a
non­
functional
production
well,
and
pipes
that
appear
to
run
from
the
former
facility
to
the
creek.

Operations
began
at
Lammers
Barrel
Factory
in
1953
and
continued
until
the
fire
in
October
1969.
According
to
former
employees,
the
facility
bought,
sold
and
reclaimed
all
types
of
solvents.
Any
inventories
of
chemicals
handled
at
the
facility
were
reportedly
destroyed
in
the
fire.
During
operation,
the
facility
had
an
above­
ground
storage
capacity
of
over
500,000
gallons.
This
consisted
of
eighteen
vertical
tanks,
ranging
in
size
from
2,500
to
25,000
gallons
and
approximately
6,000
55­
gallon
drums.

Sampling
of
residential
wells
began
in
the
mid­
1980s.
In
1985,
analyses
of
approximately
90
residential
well
samples
throughout
Beavercreek
identified
an
area
of
ground
water
contamination
along
the
northern
end
of
the
Valleywood
subdivision,
located
southeast
of
the
facility.
Sampling
revealed
that
the
presence
of
vinyl
chloride
was
above
the
federal
maximum
contaminant
level
(MCL)
for
drinking
water
in
some
wells.
Several
wells
contained
other
volatile
organic
compounds
(VOCs),
such
as
chloroethane,
1,2­
dichloroethene,
perchloroethylene,
and
trichloroethylene.
As
a
result,
the
Ohio
National
Guard
brought
a
350­
gallon
mobile
water
tank
as
an
emergency
water
supply
to
five
homes
along
Patterson
Road.
Nine
homes
that
exceeded
removal
action
levels
of
VOCs
in
drinking
water
were
subsequently
connected
to
the
county
municipal
water
system.

Periodic
ground
water
sampling
has
continued
since
1985,
resulting
in
the
extension
of
the
county
water
line
or
installation
of
filtration
systems
at
several
homes.
Sampling
efforts
in
1988,
1991
and
1997
show
that
the
contaminated
ground
water
plume
has
advanced
into
the
adjacent
Valleywood
subdivision.
In
1992,
Ohio
Environmental
Protection
Agency
(EPA)
conducted
a
Site
Inspection
(SI)
at
the
site.
Six
soil
samples,
four
sediment
and
four
surface
water
samples
from
Little
Beaver
Creek
were
collected
along
with
additional
residential
well
samples.
The
six
soil
samples
from
the
site
indicate
the
presence
of
VOCs,
lead
and
polychlorinated
biphenyls
(PCBs).
The
creek
sediment
samples
revealed
low
concentrations
of
xylenes
and
heavy
metals.

An
Engineering
Evaluation/
Cost
Analysis
(EE/
CA)
was
prepared
for
the
U.
S.
EPA
in
1997.
Soil,
sediment
and
ground
water
samples
were
collected
in
March,
April,
June
and
August
of
1997.
A
total
of
71
residential
well
samples
from
54
homes
were
collected.
VOCs
were
detected
in
28
of
the
wells
sampled
serving
54
homes.
Most
of
the
homes
sampled
had
been
sampled
in
previous
investigations.
Some
samples
were
collected
from
residential
wells
at
homes
that
had
already
been
connected
to
the
municipal
system
to
identify
the
extent
of
the
plume.
Sediment
samples
collected
from
Little
Beaver
Creek
identified
the
presence
of
VOCs
and
semi­
volatile
organic
compounds
(SVOCs).

Soil
contaminant
concentrations
indicate
two
potential
source
areas
for
ground
water
contamination,
on
each
side
of
Little
Beaver
Creek.
Both
areas
of
subsurface
soil
contamination
lie
near
the
level
of
the
water
table.
Similar
VOCs
were
detected
in
both
on­
site
soil
and
monitoring
well
samples,
and
off­
site
residential
well
samples.
Concentrations
of
VOCs
in
on­
site
soils
indicate
that
they
may
be
the
source
of
the
ground
water
contamination
plume.

Similar
contaminants
were
also
detected
in
on­
site
sediment
and
soil
samples,
indicating
that
the
site
may
actually
be
impacting
the
sediments
and
associated
water
quality
of
Little
Beaver
Creek.
Little
Beaver
Creek
flows
into
the
Little
Miami
National
and
State
Scenic
River,
a
popular
recreation
and
wildlife
area.
Possible
targets
along
the
river
in
the
vicinity
of
the
site
include
a
human
food
chain
fishery,
wetlands
and
a
state
threatened
species.

The
Lammers
Barrel
property
is
now
vacant,
approximately
two
acres
in
size,
and
located
in
Beavercreek,
Ohio
(Ref.
7,
p.
2,
Figures
1
and

The
property
is
bisected
by
Little
Beaver
Creek
which
flows
west
to
east
through
the
site.
The
property
is
bordered
to
the
west
and
south
by
Grange
Hall
Road
and
East
Patterson
Road,
respectively.
An
abandoned
railroad
right
of
way
makes
up
the
northern
border
(Ref.
7,
p.
1;
figure
1).
The
facility
experienced
a
fire
in
1969
that
completely
destroyed
the
buildings
and
any
record
of
operations
(Ref.
17,
p.
2).
The
only
structures
remaining
are
a
concrete
pad,
a
non­
functional
production
well,
and
pipes
that
appear
to
run
from
the
former
facility
to
the
creek
(Ref.
10,
p.
3).

Operations
began
at
Lammers
Barrel
Factory
in
1953
and
continued
until
the
fire
in
October
1969
(Ref.
10,
p.
5).
According
to
Anthony
Kohnen,
the
co­
owner
of
Lammers
Barrel
Factory,
the
facility
bought,
sold
and
reclaimed
most
all
industrial
solvents
(Ref.
10,
p.
6).
Any
inventories
of
chemicals
handled
at
the
facility
were
reportedly
destroyed
in
the
fire
(Ref.
17,
p.
2).
During
operation,
the
facility
had
an
above­
ground
storage
capacity
of
over
500,000
gallons
(Ref.
6,
p.
2).
This
consisted
of
eighteen
vertical
tanks,
ranging
in
size
from
2,500
to
25,000
gallons
and
approximately
6,000
55­
gallon
drums
(Ref.
10,
p.
5).
The
amount
of
chemicals
onsite
at
the
time
of
the
fire
is
unknown.
It
is
believed
that
the
contaminated
soil
resulted
from
normal
operations
and
exploding
drums
and
tanks
during
the
fire
(Ref.
17,
p.
2)

Little
Beaver
Creek
flows
from
west
to
east
through
the
site
and
divides
it
into
two
areas.
The
contaminated
soil
at
the
site
is
located
on
either
side
of
Little
Beaver
Creek.
Both
areas
of
subsurface
soil
contamination
lie
near
the
level
of
the
water
table
(Ref.
5,
p.
2­
18).
Approximately
two­
thirds
of
the
contaminated
soil
is
located
on
the
southern
portion
of
the
property
where
the
structures
at
the
facility
were
once
located
(Ref.
7,
figure
7).
Four
above
ground
storage
tanks,
used
to
store
`dirty'
solvents
from
customers,
and
a
pump
house
were
formerly
located
on
the
property
between
the
creek
and
the
railroad
(Ref.
34,
p.
130­
131).

Geoprobe®
samples
were
collected
from
depths
of
0
to
13
feet
below
ground
surface
on
the
northern
and
southern
portions
of
the
site
(Ref.
6,
p.
3).
Based
on
the
soil
analytical
results,
the
minimum
amount
of
soil
contaminated
by
VOCs
above
the
site
remedial
action
levels
is
estimated
at
1.04
million
cubic
feet
or
38,700
cubic
yards
(based
on
a
depth
of
contamination
of
20
feet)
(Ref.
7,
p.
10,
Tables
2­
3).
More
contaminated
soil
may
be
located
at
the
site
with
concentrations
below
the
remedial
action
levels
(Ref.
7,
Table
2
and
3).
It
is
believed
that
the
soil
became
contaminated
during
normal
operations
at
the
facility
and
as
a
result
of
damage
to
the
storage
tanks
and
drums
during
the
fire
(Ref.
5,
p.
3­
2).

HAZARDOUS
SUBSTANCES
ASSOCIATED
WITH
THE
SOURCE
Soil
samples
collected
in
April
2000
were
part
of
a
hydrogeologic
characterization
performed
at
the
request
of
the
U.
S.
Army
Corps
of
Engineers
(USACE).
The
study
was
intended
to
assess
the
horizontal
and
vertical
extent
of
contamination
at
the
site
(Ref.
6,
p.
1).
Samples
collected
in
August
2000
were
part
of
the
second
phase
of
hydrogeologic
characterization
at
the
facility
also
requested
by
the
USACE.
They
were
intended
to
provide
additional
information
on
perched
water
zones,
contaminated
site
soils
and
ground
water
and
information
on
soil
and
ground
water
conditions
along
the
proposed
water
line
extension
(Ref.

for
the
site
during
the
USACE
Phase
II
Hydrogeologic

at
the
Lammers

facility,
in
June
2000.
Hazardous

were
found
at
a

Based
on
the

Aquifer/
Stratum
1
(uppermost):
surficial
glacial
outwash
deposits
Three
buried
valley
tributaries
form
the
broad
lowland
area
in
the
location
of
Beaver
Creek
Township.
This
area
is
underlain
with
permeable
sands
and
gravels
and
is
traversed
by
the
Little
Miami
River
and
Beaver
Creek
(Ref.
19,
p.
4).
The
buried
valley
aquifer
consists
of
Wisconsin­
age,
well
sorted
glacial
outwash
sand
and
gravel
deposits
(Ref.
23,
p.
1).
The
uppermost
aquifer
is
located
at
depths
between
25
and
80
feet
and
is
composed
of
highly
permeable
outwash
deposits
of
sand
and
gravel
(Refs.
23,
p.
1;
24,
p.
5).
These
deposits
provide
water
to
shallow
private
residential
wells
in
the
vicinity
of
the
site
(Ref.
23,
p.
1).
The
unconsolidated
glacial
deposits
in
the
area
are
lying
unconformably
atop
the
Ordovician
Richmond
limestone
and
Maysville
shale
bedrock
(Ref.
23,
p.
1).
The
direction
of
local
ground
water
flow
in
the
area
of
the
site
is
to
the
southeast
and
influenced
by
the
dip
of
the
bedrock
units
(Ref.
24,
p.
5).

In
most
cases,
private
water
supply
wells
have
been
installed
at
depths
of
approximately
40
to
50
feet
below
ground
surface
(BGS)
[800
to
810
feet
above
mean
sea
level
(amsl)]
(Refs.
5,
p.
2­
4;
10,
p.
4;
25).
Static
water
levels
are
generally
from
5
to
25
feet
BGS
(845­
825
feet
amsl).
Yields
of
up
to
50
gallons
per
minute
have
been
reported
for
this
aquifer.
Wells
were
generally
developed
at
flow
rates
of
8
to
10
gallons
per
minute
(Ref.
5,
p.
2­
4).
Ground
water
flow
direction
in
the
area
is
heavily
influenced
by
the
rate
of
pumping
in
local
residential
wells.
These
local
residential
wells
are
typically
not
pumped
at
a
constant
rate.
A
number
of
the
wells
are
no
longer
heavily
utilized
since
residences
were
connected
to
the
county
water
supply.
Therefore,
it
is
possible
that
the
spread
of
ground
water
contamination
in
the
area
at
any
one
time
is
a
result
of
shifts
in
ground
water
flow
direction
as
the
utilization
rates
of
residential
wells
shifted
(Ref.
5,
p.
2­
4).

Contaminated
Samples:
The
wells
below
show
contamination
at
similar
depths
and
are
most
likely
to
be
screened
in
the
same
part
of
the
aquifer.
In
most
cases,
private
water
supply
wells
have
been
installed
at
depths
of
approximately
40
to
50
feet
(810
to
800
feet
amsl)
(Ref.
10,
p.
4).
Wells
50
­
104
were
included
to
show
continuous
contamination
since
sampling
began
in
1985,
through
the
present.
Concentrations
of
hazardous
substances
were
obtained
from
the
residential
well
database.
Analytical
information
was
not
available.
These
wells
were
identified
as
having
concentrations
above
EPA
safe
drinking
water
standards
and
placed
on
the
municipal
water
system
prior
to
1997
(Ref.

Between
1953
and
1969
Lammers,
Inc.
operated
a
waste
storage
and
reclamation
facility
for
all
types
of
industrial
solvents
and
flammables
on
the
site.
The
company
would
take
in
approximately
4,000
to
5,000
gallons
of
chemicals
per
day
from
various
generators,
purify
the
solvents
and
then
return
them
to
the
generators.
According
to
former
and
present
government
officials
and
employees
familiar
with
the
site,
Lammers,
Inc.
ran
a
"sloppy
operation."
Frequent
spills
occurred
on
the
site
and
chemical
wastes
were
dumped
into
Little
Beaver
Creek,
which
runs
through
the
facility
property
(Ref.
20,
p.
5­
3).
Tony
Kohnen,
former
co­
owner
of
Kohnen­
Lammer
Chemical
Company,
stated
that
the
Lammers
Barrel
facility
accepted
most
all
industrial
solvents
primarily
from
the
paint
and
automobile
industries
including
1,1,1­
Trichloroethane
(Ref.
31).

Lammers,
Inc.
's
Articles
of
Incorporation
indicate
that
the
purpose
for
which
the
Company
was
formed
included
"To
manufacture,
reclaim,
compound,
assemble,
formulate,
amalgamate,
distill,
analyze,
manipulate,
mix,
prepare
for
market,
buy,
broker,
market,
sell,
vend,
deal
and
trade
in,
import,
export,
transport,
and
distribute,
or
in
any
manner
turn
to
account
or
dispose
of
solvents,
oil,
grease,
gasoline,
alcohol
benzol,
auto
accessories
and
parts,
tires,
or
chemical
compounds
for
treating
gasoline
and
other
liquid
fuels
and
also
for
treating
lubricating
oils
and
other
purposes,
and
any
other
compounds
or
products
known
in
industrial
chemistry
or
any
of
the
ingredients
thereof..."
(Ref.
20,
p.
5­
4).
While
petroleum
related
contaminants
are
found
in
soil
and
ground
water
samples,
these
substances
were
received
by
the
facility
as
part
of
a
mixed
waste
containing
other
man­
made
contaminants
(i.
e.
chlorinated
solvents).
Further,
no
evidence
suggests
that
the
contamination
in
the
sources
was
the
result
of
a
spill
of
petroleum
product.

Because
as
much
as
500,000
gallons
of
solvents
spilled
or
burned
at
Lammers
Barrel
and
chlorinated
solvents
were
stored
on
site,
the
samples
taken
during
the
1992
SI,
the
1997
EE/
CA,
and
the
2000
Phase
II
Hydrogeologic
Characterization
Activities,
indicated
extremely
high
levels
of
solvent
and
chlorinated
solvent
in
the
soil
(Refs.
5;
7;
10).
Substances
shown
to
have
been
released
to
the
ground
water
are
also
present
in
the
soil
at
the
facility.
Geoprobe
samples
collected
from
the
facility
show
continuous
vertical
contamination
from
as
shallow
as
12
feet
to
as
deep
as
40
feet
below
the
ground
surface
(Refs.
6,
pp.
3­
148
­
3­
154;
7,
pp.
A­
1,
A­
4,
A­
6).
This
is
characterized
by
geoprobe
location
GP­
6,
where
high
concentrations
of
ethylbenzene,
toluene
and
xylene
are
not
only
found
in
shallow
samples
(8­
12
ft),
but
also
deep
samples
(30­
34
ft)
at
the
same
location
(Ref.
6,
pp.
3­
60,
3­
61,
3­
63).

The
Ohio
EPA
Division
of
Emergency
and
Remedial
Response
lists
three
sites
within
1.5

Component
The
two­
acre
Lammers
Barrel
facility
is
located
at
the
intersection
of
Grange
Hall
Road
and
East
Patterson
Road.
Little
Beaver
Creek
divides
the
property
into
northern
and
southern
portions,
which
are
approximately
equal
in
size.
Little
Beaver
Creek
flows
from
west
to
east
across
the
property
(Ref.
7,
pp.
1,
2;
Figure
1).
Several
pipes
can
be
observed
leading
from
the
southern
portion
of
the
property
into
the
creek.
On
the
southern
side
of
the
property,
the
creek
banks
slope
steeply
downward
eight
to
ten
feet
to
the
creek.
The
remainder
of
the
southern
portion
of
the
property
is
flat
(Ref.
5,
p.
2­
2).
Evidence
of
concrete
building
foundations
remain
on
portions
of
the
southern
side
of
the
property.
Small
trees
and
brush
cover
the
area
between
the
concrete
foundations
and
the
southern
bank
of
the
creek
(Ref.
5,
p.
2­
2).
The
northern
portion
of
the
property
also
has
steeply
sloping
banks
down
to
the
creek.
In
this
area,
there
are
numerous
small,
vegetation­
covered
soil
piles
adjacent
to
the
creek.
Remnants
of
a
dirt
access
road
are
visible
along
the
railroad
right­
of­
way,
comprising
the
northern
border
of
the
property.
The
northern
portion
of
the
property
is
more
heavily
vegetated
than
the
southern
portion
(Ref.
5,
p.
2­
2).

Runoff
from
rainfall
on
the
contaminated
soil,
in
the
northern
portion
and
southern
portion
of
the
property,
drains
into
Little
Beaver
Creek
(Ref.
3).
Because
there
are
many
locations
along
the
creek
bed
that
hazardous
substances
can
enter
the
stream,
the
entire
length
of
the
stream
segment
is
considered
the
probable
point
of
entry
(PPE)
for
the
contaminated
soil
source
(Ref.
3).
Little
Beaver
Creek
extends
from
the
most
downstream
PPE
at
the
site,
3.
4
miles
to
the
confluence
of
Beaver
Creek.
Beaver
Creek
flows
south
into
the
Little
Miami
River
1.
1
miles
from
the
previous
confluence.
The
target

Between
1953
and
1969
Lammers,
Inc.
operated
a
waste
storage
and
reclamation
facility
for
all
types
of
industrial
solvents
and
flammables
on
the
site.
The
company
would
take
in
approximately
4,000
to
5,000
gallons
of
chemicals
per
day
from
various
generators,
purify
the
solvents
and
then
return
them
to
the
generators.
According
to
former
and
present
government
officials
and
employees
familiar
with
the
site,
Lammers,
Inc.
ran
a
"sloppy
operation."
Frequent
spills
occurred
on
the
site
and
chemical
wastes
were
dumped
into
Little
Beaver
Creek,
which
runs
through
the
facility
property
(Ref.
20,
p.
5­
3).
Tony
Kohnen,
former
co­
owner
of
Kohnen­
Lammer
Chemical
Company,
stated
that
the
Lammers
Barrel
facility
accepted
most
all
industrial
solvents
primarily
from
the
paint
and
automobile
industries
(Ref.
31).
The
substances
identified
in
the
observed
release
to
surface
water
were
also
found
in
the
contaminated
soil
on­
site.

Lammers,
Inc.
's
Articles
of
Incorporation
indicate
that
the
purpose
for
which
the
Company
was
formed
included
"To
manufacture,
reclaim,
compound,
assemble,
formulate,
amalgamate,
distill,
analyze,
manipulate,
mix,
prepare
for
market,
buy,
broker,
market,
sell,
vend,
deal
and
trade
in,
import,
export,
transport,
and
distribute,
or
in
any
manner
turn
to
account
or
dispose
of
solvents,
oil,
grease,
gasoline,
alcohol
benzol,
auto
accessories
and
parts,
tires,
or
chemical
compounds
for
treating
gasoline
and
other
liquid
fuels
and
also
for
treating
lubricating
oils
and
other
purposes,
and
any
other
compounds
or
products
known
in
industrial
chemistry
or
any
of
the
ingredients
thereof..."
(Ref.
20,
p.
5­
4).
While
petroleum
related
contaminants
are
found
in
soil
and
ground
water
samples,
these
substances
were
received
by
the
facility
as
part
of
a
mixed
waste
containing
other
man­
made
contaminants
(i.
e.
chlorinated
solvents).
Further,
no
evidence
suggests
that
the
contamination
in
the
sources
was
the
result
of
a
spill
of
petroleum
product.

The
Ohio
EPA
Division
of
Emergency
and
Remedial
Response
lists
three
sites
within
1.5
miles
of
the
Lammers
Barrel
facility
that
could
contribute
similar
contaminants
to
the
ground
water
(Ref.
26,
Figure
1).
These
sites
are
located
downstream
from
the
Lammers
Barrel
facility
and
would
not
be
able
to
contribute
to
the
contaminated
sediment
located
in
the
stream
segment
on
the
property
(Ref.
26,
Figure
1).
Upstream
from
the
facility
is
a
waste
water
treatment
plant.
This
plant
has
not
contributed
to
the
contamination
on­
site
according
to
samples
collected
between
the
Lammers
Barrel
facility
and
the
treatment
plant
(Ref.
5,
pp.
2­
73,
2­
74;
8,
pp.
4­
18,
6­
22).
In
addition,
the
USEPA's
listing
of
hazardous
waste
handlers
documents
that
there
have
been
no
known
releases
to
the
surface
water
upstream
of
the
site
within
1
mile
(Ref.
33).
