ROD SUMMARIES
FLORENCE LAND RECON-
TOURING LANDFILL
REGION II, NEW JERSEY
(Approved 6/27/86)
Description:
•	This 29-acre landfill is con-
structed over an aquifer that is
a major source of drinking
water. Leachate from the land-
fill could potentially infiltrate
the aquifer. The landfill was
given permits to accept non-
chemical sanitary and in-
dustrial sludge, septage, and
sewage sludge throughout the
1970s. Investigations showed
that chemical wastes had
been disposed of onsite. A
consent order defining control
measures to be undertaken by
the owners was issued in 1979.
Compliance was spotty;
leachate control was inade-
quate. Local domestic wells
show levels of contamination
below minimum drinking water
standards, although there is
evidence of migration of con-
taminants offsite.
Decision:
•	Construct ground water inter-
ceptors, stormwater manage-
ment system, slurry contain-
ment wall, and cap around
contaminants.
•	Treat and dispose of leachate
offsite.
•	Collect gas and treat.
•	Remove and dispose of lagoon
liquids, sediments, and other
debris.
•	Construct fence; post warning
signs; sample ground water,
surface water, and sediments
during design.

METALTEC/AEROSYSTEMS
REGION II, NEW JERSEY
(Approved 6/30/86)
Description:
•Two manufacturing busi-
nesses operate onsite. Two
aquifers underlying the site
have been contaminated with
organic chemicals. The
aquifers are used to provide
the drinking water supply for
both municipal and private
wells. Water supply wells for
the Borough of Franklin and
three domestic wells were
removed from service in 1980.
In 1981, an administrative
order was issued to the
Metaltec Corporation to clean
up existing contamination and
conduct a hydrogeology study.
The order was not fully com-
plied with; EPA took the lead
for site activities in 1984.
Decision:
•	Excavate and dry 10,000 cubic
yards of contaminated soils;
excavate 4,000 additional
cubic yards of contaminated
soils; dispose of offsite.
•	Prepare a supplemental RI/FS
to identify the extent of
ground water contamination
and evaluate remedial alter-
natives.
•	Provide alternate water supply
for Borough of Franklin
residents by constructing a
pipeline to Borough of Ham-
burg system.

MILLCREEK SITE
REGION III, PENNSYLVANIA
(Approved 5/07/86)
Description:
• The site was a wetland that
was filled in with founds slag,
except for 2 acres in the
southern portion. Unpermit-
ted disposal activities oc-
curred on this 84.5-acre site.
Surficial soils and ground
water underlying the site are
contaminated with a wide
variety of organic chemicals
and metals. Shallow ground
water discharges into an adja-
cent stream, which has an
abundance of aquatic life and
discharges into Lake Erie. Af-
fected ground water is not
currently used as a drinking
water source. Seventy-five
liquid-filled drums were re-
moved under a planned re-
moval process in November
1983.

-------
Decision:
•	Excavate and consolidate
soils and sediments under
RCRA cap.
•	Pump and treat contaminated
ground water to meet a target
10"6 risk level, with at least a
1CM risk level attained within
2 years.
•	Construct surface water
management basins and
ditches.
•	Construct monitoring wells to
assist with remedial design
and to be used for monitoring
over at least a 2-year period.
•	Cover remaining soils, which
contain low levels of con-
taminants, with uncontami-
nated soil.
Issues:
•	Although ground water is not
currently used for drinking
water downgradient of the
site, ground water remedia-
tion to a target level of 10-6
and a 2-year time frame was
selected because effective in-
stitutional controls and pro-
tection of environmental
receptors could not be en-
sured over the 125 years
estimated for natural attenua-
tion of the contaminant
plume. At the end of 2 years,
the risk level will be assessed
to determine what additional
measures, if any, are needed
to reach the 10~6 risk level.
•	Proposed soil criteria to be
reevaluated during design.

WESTLINE SITE
REGION III, PENNSYLVANIA
(Approved 7/03/86)
Description:
•	A plant onsite produced char-
coal, acetic acid, and metha-
nol from lumber from the turn
of the century until the
mid-1950s. Waste tar deposits
that exhibit low levels of poly-
nuclear aromatics are found
throughout the site. The un-
derlying aquifer is used for
the domestic water supply. In
1983, the largest of the waste
tar deposits was removed as
an emergency action under
CERCLA.
Decision:
•	Excavate waste tar and inciner-
ate offsite; backfill and re-
vegetate excavated areas.
•	Target cleanup level is 10"
risk level (similar to back-
ground levels found) based on
contact with soils over a
20-year period. The target
cleanup level for the soil will
also ensure that a 10-6 risk
level will not be exceeded in
the ground water.
•	Monitor air quality; conduct
ground water contamination
verification study.
Issues:
•	Vocal members of community
preferred no action alter-
native.

A.L. TAYLOR SITE
REGION IV, KENTUCKY
(Approved 6/18/86)
Description:
•	The site was used for in-
dustrial waste disposal. Re-
quired waste disposal permits
were never acquired by the
owner/operator of the site.
The site has been known as
the "Valley of the Drums";
over 17,000 drums were inven-
toried on the surface in 1970.
Underlying ground water is
unusable for drinking water
and has never been used as a
water supply. A small creek
subject to seasonal flows is
adjacent to the site. In 1979,
under the authority of the
Clean Water Act, EPA pre-
vented further release of pol-
lutants into the creek by con-
structing surface water con-
trols, securing leaking drums,
and segregating and organiz-
ing drums onsite. In 1980, six
potentially responsible par-
ties removed approximately
30 percent of the waste on the
surface. In 1981, EPA removed
the remaining 4,200 drums on
the surface as an emergency
action.
Decision:
•	Consolidate and cap con-
taminated sediments, sludge,
and materials.
•	Construct surface water divei
sions; monitor site.
•	Construct chain link fence
around site.
Issues:
•	No action on ground water is
anticipated because of the
Class III characteristics and
low yield of the affected
aquifers, which are not cur-
rently used nor expected to be
used as drinking water
sources.

NEW BRIGHTON/
ARDEN HILLS/ST. ANTHONY
REGION V, MICHIGAN
(Approved 6/30/86)
Description:
•	A large aquifer that supplied
drinking water for sever-
al communities was con-
taminated by four possible
sources: an industrial area, a
second commercial/industrial
area, an ammunition plant
and several sites located with
in a kame deposit. Several ini-
tial remedial measures have
been implemented to protect
New Brighton's water supply.
TCEs and VOCs are the prima-
ry contaminants.
Decision:
•	Construct new well into Mt.
Simon-Hinckley aquifer
system to replace New
Brighton Well No. 7.
Issues:
•	Comprehensive Rl and phas-
ed FS currently being con-
ducted at the site by the state.
Possibility of further remedial
actions in the future to ad-
dress contamination in entire
aquifer.

NOVACO INDUSTRIES
REGION V, MICHIGAN
(Approved 6/27/86)
Decision:
•	A plating operation used an
underground tank to hold
chromic acid. The tank leaked
an unknown quantity of con-
taminant into a shallow sandy
aquifer used for the residen-
tial and commercial water
supply. This aquifer may
transmit to an aquifer in lime-
stone bedrock below. The
owner/operator treated water
onsite from July to November
1979 but did not remove all of
the chromium. Hexavalent
chromium was found in drink-
ing water supplies in 1984 and
1985. Wells have been con-
structed into the deeper
aquifer for all those who use
ground water as a source of
drinking water.
Decision:
•	Extract ground water, treat
onsite, and discharge into sur-
face water.

ONSITE INSIGHTS	
This is the first installment in a
new series of ongoing articles
we hope to include as a semi-
regular feature of the ROD
Update. ONSITE INSIGHTS will
provide you with glimpses of
new technologies and tech-
niques used by your colleagues
at Superfund sites around the
country. We will report on new
remedial technologies, new tech-
niques for field investigations,
new applications of existing
remedial technologies, useful
program and contract manage-
ment techniques, and interest-
ing results of remedial actions.
The focus is on technology, but
we will report on anything that
might have useful applications
for you in your daily work.

there are interesting or impor-
tant new techniques being
CECIL LINDSEY
REGION VI, ARKANSAS
(Approved 4/23/86)
Description:
•	This privately owned 5.2-acre
site was used for waste dis-
posal and salvage from the
early 1970s to about 1980. In-
dustrial wastes were probably
disposed of onsite. No pri-
mary drinking water stan-
dards were exceeded in any
onsite ground water samples.
Decision:
•	Restrict site access; install
monitoring wells.
•	Monitor ground water for one
year using monitoring wells
and existing onsite wells.
•	Remove and dispose of con-
tainerized waste.

UPDATE ON MULTI-SOURCE
GROUND WATER
REMEDIATION AT BISCAYNE
AQUIFER, REGION IV
Where a Superfund site is only
one among a number of signifi-
cant contributors to ground
water contamination, EPA is in
favor of cooperating with other
responsible entities to remediate
the problem jointly and com-
prehensively. A ROD has been
produced for a multiple source
ground water contamination area
involving a significant aquifer in
and disposed of oily sludge
wastes in parking lots and in
drainage ditches for dust con-
trol. A ground water infiltra-
tion gallery underlying the site
is used for the water supply
for the City of Des Moines. A
major local river runs adjacent
to the site. TCE is the indi-
cator contaminant.
Decision:
•	Extract and collect con-
taminated ground water;
isolate portion of aquifer con-
taining contaminants.
•	Treat ground water with air
stripping technology to
remove 96 percent of the TCE.
•	Operate wells until effluent
contains less than 5
micrograms per liter of TCE
for 4 consecutive months.
Issues:
•	Source control operable unit
to follow; duration of opera-
tion of some extraction wells
to be determined as a part of
source control operable unit.

Florida. The ROD included a
20-point protection plan that re-
quired implementation of ground
water protection activities by
three local governments. Results
have been promising; all three
governments have begun to im-
plement portions of the plan.

COST-SAVING SAMPLING
TECHNIQUES IN ARIZONA,
REGION IX
The Spinner logging technique
involves the use of a down hole
flow meter to measure flows at
different levels. Depth-specific
water quality samples are taken,
and temperature, conductivity,
and gamma logs are run. This
technique has been used in

-------
Florida but has not previously
been used at hazardous waste
sites.
Spinner logging and depth of ex-
isting production wells will be
used by the Rl contractor at the
Indian Bend Wash and Phoenix-
Litchfield sites in Arizona. Rl
costs will be reduced because
the number of depth-specific
wells will be reduced. Solvent-
contaminated ground water ex-
tends over 15 square miles to a
depth of 1,000 feet through a
multi-layered alluvial aquifer
system.

A LINE ON RODS mmm
FY'85 ROD
Annual Report Available
The Hazardous Site Control Divi-
sion published the FY'85 ROD
Annual Report on June 30,1986.
This report presents summary
statistics of the types of
remedies selected in Records of
Decision (RODs) approved last
fiscal year and provides in-
dividual summaries of each ROD
that highlight performance
targets and the use of institu-
tional controls. The report con-
cludes with a key word index
and an overall Index of Approved
Remedial Actions, which in-
cludes all Records of Decision
signed through September 30,
1985. Copies of this report have
been mailed to the Superfund
Branch Chiefs, Waste Manage-
ment Division Directors,
Regional Counsels, and libraries
in the Regions and have been
circulated throughout Head-
quarters.

FY'86 RODs Considering
Treatment
A review of FY'86 RODs ad-
dressing source control actions
showed that treatment
technologies are being
evaluated in the RI/FS. The im-
portance of evaluating treatment
technologies and closely
evaluating the long-term effec-
tiveness of each remedy was
discussed in Win Porter's
August 14 memorandum to the
Regional Administrators
("Superfund Priorities for Fourth
Quarter FY'86"). Attachment B
of that memorandum provides
"Interim Guidance for Encourag-
ing Selection of Treatment/
Destruction Technologies,"
which should help Regions
justify remedies that include
treatment technologies.
