The Regional RPM requested that the ESD-LV TSC provide assistance in evaluating the feasibility of
implementing natural attenuation as the remedial remedy for groundwater contamination at this site.

The Otis Air National Guard Base (NGB) and Camp Edwards covers approximately 3,900 acres on a 22,000-
acre parcel of land, today known as the Massachusetts Military Reservation (MMR).

In 1984, the U. S. Geological Survey detected contaminants in the monitoring wells downgradient of the plant.
In 1983 and 1984, the Air Force detected volatile organic compounds (VOCs) in on-site monitoring wells near
the Base Landfill and Current Fire Training Area. Monitoring by the Air National Guard and the State
Department of Environmental Quality has detected VOCs in more than 200 private wells.

TSC reviewed the Focused Feasibility Study for Landfill-1 (draft) to address several issues including evaluating
the evidence that: natural attenuation of chlorinated ethenes was occurring in the aquifer downgradient of
Landfill-1, natural attenuation would be sufficient as a sole remedy for managing the plume of contaminated
groundwater emanating from Landfill-1, active remedial measures (such as pump-and-treat) would inhibit
biodegradation of chlorinated ethenes, decreasing concentration trends are the result of installation of a landfill
cap instead of natural attenuation, and finally, reviewed the cost estimates of various remedial alternatives. In
spite of the extremely short review period, the TSC (INEEL) participated in two meetings at the site with
regulators and the Air Force, as well as numerous tele conferences in which natural attenuation and other
remedial alternatives were discussed. At the request of Region I, a series of documents was provided that
describe a groundwater remediation program at the INEEL Test Area North facility. The TSC reviewed the
addendum to the focused feasability study for Landfill-1 and participated in a number of
tele-conferences and attended a meeting to discuss TSC comments and suggestions. The RPM will provide the
TSC with extraction/treatment system data for review. The TSC received a request to assist in the
establishment of conservative soil concentration for explosive residues and other contaminants based on
leaching to groundwater. An evaluation of the SESOIL Model was completed. In addition, a data report titled
"Soil Action Levels for Massachusetts Military Reserve Northern Impact Area" was provided to the Region.

The TSC was requested to review DoD's site specific fate and transport measurement Task 2000. The TSC
completed a review of the modeling portion of the RI for the chemical spill-19 (CS-19) area. The TSC
-------
calculated some additional soil screening concentrations that were provided to the Region. TSC reviewed
"Contaminant of Concern Identification Demolition Area 1" and the "Draft Modeling Strategy for the Camp
Edwards Impact Area Groundwater Quality Study

• Project Name: Ottati

Type Lead:
Requested by: Dick Goehlert (617) 918-1335
Lead Scientist: Kent Snyder (360) 546-0687
Start Date: August 1999
Expected Completion Date: March 2000
Revised Completion Date: May 2001
Estimated Budget: $12,000 Total Expenditures:$57,438.
Revised Budget:$95,000 Total FYO1 Exps: $ 1,100.
Major Contaminants: PCB's Total 2nd Qrr. Exps:$ 1,000.

The RPM requested that the BSD, TSC provide assistance in designing and identifying sampling methodologies
for sampling hummocks.

The Ottati & Goss/Kingston Steel Drum site in Kingston, N.H. is situated on 35 acres, contains a 1-acre parcel
in the southwest portion that was leased and known as the Ottati & Goss (O&G) site and a 6-acre Great Lakes
Container Corporation (GLCC) site consisting of a rectangular parcel bordered on the east by Route 125. From
the late 1950s through 1967, Conway Barrel & Drum Company (CBD) owned the site and performed drum
reconditioning operations on the parcel of land later owned by the Great Lakes Container Corporation. The
reconditioning operations included caustic rinsing of drums and disposal of the rinse water in a dry well nearby.

The groundwater, surface water, and soils are contaminated with volatile organic compounds (VOCs). The on-
site soil also contains polychlorinated biphenyls (PCBs), metal, and acids and base/neutral compounds.

The TSC participated in a conference call and provided comments and recommendations pertaining to a
proposed sampling plan. The TSC reviewed and provided comments pertaining to the sampling plan and
quality control sections of the 90% design contract specifications. In addition, a report titled "Assessment of
Arsenic Distribution in Ottati and Goss Soils" was completed and provided to the Region.

The TSC reviewed the sampling quality control and wetland restoration sectors of the 100% design contract
specifications document. A number of letter reports on this review was provided to the Region. Also, several
issues, including the arsenic report, were discussed with the RPM. The TSC reviewed and provided comments
to the RPM on the "Compendium of Quality Assurance Project Plan Requirements and Guidance." The TSC
participated with the Region and USAGE in discussions on the "Sampling Procedures and Laboratory Services"
of the Ottati & Goss 100% design document. The "100% Design Document" was reviewed by the TSC. The
report titled "Review of Ottati and Gas Soil Remediation 100% Design" was provided to the Region.
Additional support is anticipated.

Project Name: Savage Well
Site: Savage Well Municipal Water Supply OU-2 S. F. Site
Site ID:
-------
Type Lead:
Requested by: Richard Goehlert (617) 918-1335
Lead Scientist: Lance Peterson (208) 526-9738

Start Date: May 1999
Expected Completion Date: December 1999
Revised Completion Date: April 2001

Estimated Budget: $20,000 Total Expenditures:$22,051.
Revised Budget: $30,000 Total FY01 Expenditures:$610.
Major Contaminants: Organics Total 2nd Qtr. Expenditures^ 110.

The RPM requested that the ESD-LV TSC provide assistance in reviewing aquifer models that are and/or will
be used to determine appropriate remedial approaches.

The Savage Well site covers about 30 acres west of the center of Milford, NH and consists of a municipal well.
The underlying aquifer, the water-bearing layer of rock and gravel from which the Town of Milford gets its
water. The Savage Municipal Well site operated form 1960 to 1983, during which time it supplied 40% to 45%
of Milford's water. The remainder of the water came from the Keyes and Kokko Wells. During Savage's years
of operation, several metal industries opened plants near the well along the Souhegan River. Investigations at
the site identified the source of contaminants, which also were present in water samples taken at the nearby
industries.

The groundwater is contaminated with VOCs, including TCE and vinyl chloride and heavy metals, including
lead, chromium, and mercury. The soil is contaminated with VOCs. The stream on site is contaminated with
VOCs and lead. As previously identified the TSC has been involved at OU-1 with the "Surfactant-Enhances
Aquifer Remediation of PCE at Neutral Buoyancy" Project.

The PRPs have modeled the Savage Well aquifer and evaluated several remedial scenarios. They have come to
the conclusion that monitored natural attenuation remedy will result in a clean aquifer in about the same time as
an engineered remedy. This does not seem to make sense given the complexity of the aquifer and the broad
extent of contamination in OU-2. OU-1 is a fund lead slurry wall, with pump and treatment system, SVE air
sparging, and air stripping. OU-2 is a dissolved plume downgradient from the OU-1 area.

Numerous reports were received on hydrologic modeling of Savage Well OU-2 site. The hydrologic site
conceptual model review is in progress and will be followed by a numerical model review. Questions and
comments are being formulated as review progresses. The TSC has performed an initial review on the QST
Draft Modeling report and the Remedial Design Report. The modeling review was completed and the report
titled "Comments Regarding Modeling and Interpretations on the OU-2 Savage Well Site" was provided to the
Region. The TSC received the 1999 USGS groundwater modeling report. The report was reviewed and was
considered satisfactory. Discussion with the RPM pertaining to the transport models "ModFlow" and
ModFlow/MTSD occurred.

The TSC reviewed the document "An Evaluation of June and August 2000 Sampling Results: Biotic
Transformation of Chlorinated Organic Compounds Within the Extended Plume, Savage Well ESE." A
number of conference calls pertaining to modeling questions were held with the RPM.

The Regional Remedial Project Manager (RPM) requested that the Environmental Sciences Division-Las Vegas
(ESD) Technology Support Center (TSC) provide assistance in a statistical assessment of false positive and
false negative data as defined and used in the site's QAPP. South Weymouth Naval Air Station (SWNAS) is
located at the southern end of Weymouth, Norfolk County, Massachusetts. SWNAS is approximately 1,500
acres in size. Station generated wastes is disposed of in three onsite landfills. The West Gate landfill operated
from 1969 to 1972. The Rubble Disposal area and the Small landfill operated from 1972 until the mid-1980's.
Flammable liquid wastes were reportedly burned in the onsite fire fighting training area. Small amounts of
waste battery acid, possibly containing lead, may have been disposed of in a site leach field.

The TSC reviewed the QAPP and site data. Following the review and site documents assessment the TSC
provided the Region the report titled "Review of Statistical Approaches Proposed for South Weymouth
Superfund Site". Following a review of additional data, the TSC provided the Region with two reports titled
"Review of statistical approaches Proposed for South Weymouth Naval Air Station NPL site and "Review
Comments on the Approach Proposed by the Navy for Background and Review Action Item Concentration
Comparison, South Weymouth NPL Site". Following a PRP/EPA conference call an additional assessment of
site data the report titled "Review of Statistical Approaches Proposed for South Weymouth Naval Air Station
NPL Site, 5-19-99" was provided to the Region. In July the TSC was provided a Phase II BBS-Data Analysis
Update-RTN#3-2621, dated July 7, 1999. Following a review of additional site data and documents, the TSC
provided the following reports to the Region: "Use of SWNAS Background Data Set for Evaluation of the
Environmental Base Line Study Review Item Area Data" dated December 8, 1999, and "Background Data Set
Development for NAS South Weymouth Revision No. 2". A number of letter reports were provided to the
Region. These reports included comments on the draft human health risk assessment work plan, background
UPL computations and the issue of outliers. The TSC is currently reviewing the PRP's approach for the
background screening comparison used for the "small landfill."

The TSC completed the review of the "PRP's Background Screening Approach". The RPM had a number of
questions pertaining to the Phase II RI. These questions were addressed by the TSC. Additional support is
anticipated.

Revised Budget: $ Total FYO1 Exps:$300. PC&B:$800
Major Contaminants: Organics Total 2nd Qtr. $300. PC&B:$800

The RPM requested that the ESD-LV TSC provide assistance in reviewing a suggested Creel/Angler survey.

The Diamond Alkali Company site covers 3-acres in Newark, New Jersey adjacent to the Passaic River. The
site has been used for chemical manufacturing by numerous companies for more than 100 years. The mid-
1940s marked the beginning of the manufacturing operations related to the current site conditions, including the
production of DDT and phenoxy herbicides. The Diamond Sheetrock Company acquired the property in 1951
and produced various chemicals and pesticides until 1969, when it was shut down.

Dioxin has been detected in on-site monitoring wells. Other contaminants detected in groundwater included
volatile organic compounds (VOCs) including benzene, acetone, and toluene and herbicides. Individuals
accidentally ingesting contaminated soil or surface water may be at risk, as may those using contaminated
groundwater for other uses. The Passaic River and fish and shellfish from the river may be threatened by
runoff from the site.

The TSC is currently reviewing provided site information and documents.

The RPM requested that the ESD-LV TSC provide assistance in reviewing a number of site documents i.e.,
treatability study work plan, Remedial Investigation Report for Operable Unit 3 and the Feasibility Study
Report for Operable Unit 3.

The site is located on a 14-acre tract of land in Hicksville, New York. The site includes two main production
plants, a pilot plant located between these plants, a warehouse building, an administration and laboratory
building, numerous above-ground chemical storage tanks and associated pipping, and several recharge basins.
Since 1946, the facility was used for the production of various polymers, including polyvinyl chloride (PCV),
styrene/butadiene latex, vinyl chloride/vinyl acetate copolymer, and polyurethane, as well as ester plasticizers.
The facility is currently active, and manufactures such products as polyester, polyols and powder coating
resins. During site operations, industrial wastewater from the facility was discharged to six (6) on-site recharge
-------
basins or sumps. The wastewater contained, among other things, vinyl chloride, trichloroethylene, barium and
cadmium soap. Vinyl acetate, organic acids, and styrene condensate as a result of these releases, groundwater
downgradient from the site has been contaminated.

The TSC reviewed the Predesign Work Plan for Operable Unit I with a specific focus on the Treatabiliry Study
Work Plan (Appendix C). Comments were provided within two days of receipt of the document. Significant
deficiencies were noted in the Treatability Study Work Plan. Recommendations for resolution of the
deficiencies were made in the review comments and discussed on a conference call with EPA Region II and the
PRPs. An additional review was completed on the Remedial Investigation Report Operable Unit-3. The report
summarized existing data and the reviewers agreed with recommendations for additional monitoring of wells.
The reviewers did not agree with the conclusion that the existing data was adequate for a section of a final
remedy and recommendations were made for additional data needs to fully evaluate remediation alternatives.

The TSC reviewed and provided comments pertaining to the report "Feasibility Study for Operable Unit-3
Vinyl Chloride Sub-Plume in the Vicinity of MW-S2 Hicksville, New York-KS-0599 and LMP-05-99". The
TSC supplied comments to the RPM on an Interim Remedial Measures plan that calls for additional
characterizing and preliminary tests to support biosparging at the Hooker/Ruco site. This work would be
performed concurrently with fmalization of the RI/FS and drafting of the ROD. A review of the comment
responses provided by OXY for the Hooker/Ruco site RI and FS reports was completed and provided. At the
request of Mr. Quadri the groundwater treatability study report was reviewed and the TSC completed a review
of the comment responses on the RI and FS reports provided to the EPA by OXY for the Hooker/Ruco site.
TSC transmitted written comments on the Groundwater Treatability Study Report and the In Situ Chemical
Oxidation Work Plan as well as a summary of the reviews of comment responses on the RI/FS documents. A
number of conference calls between the TSC scientists, the RPM and the PRP's were completed. The TSC
provided input into the sampling methods that will be performed during installation of wells for the pre-design
activities associated with OU-3. The TSC reviewed and provided comments to the RPM on the remedial
investigation report OU-3. Following the PRP's revision of the "Feasibility Study Document for OU-3" the
TSC reviewed the revised version and provided some additional recommendations.

The TSC was requested to review public comments and Northrop Grumman responses. The following two
reports were provided to the Region: "Responses to Public Comments on the Proposed Plan for the Vinyl
Chloride Sub-plume at the Hooker Chemical/Ruco Polymer Plant in Hicksville, New York" dated September
13, 2000, and "Proposed Response to Northrop Grumman Corporation Comments dated August 28, 2000 on
the Operable Unit-3 Proposed Remedial Action Plan for the Hooker/Ruco Site, Hicksville, New York" dated
September 18, 2000. A number of conversations with the RPM occurred pertaining to TSC comments and
suggestions. A workshop on fractured rock was attended by a TSC representative. The TSC provided
comments and suggestions on the OU-3 proposed remedial action plan. The TSC participated in a number of
conference calls with the RPM.

Major Contaminants: Freon 11 Total 2nd Qtr. Expenditures:$0

The RPM requested that the ESD-LV TSC provide assistance in identifying the fate and transport of Freon 11
in subsurface (i.e., soil and groundwater) environments and to review the sampling/sample handling and
analytical methods that will be used by the PRP's to characterize Freon 11 at this site.

The Hudson Technologies Inc. (HTI) site is an active freon recycling facility located at 25 Torne Valley Road
in Hillbum, Rockland County, New York. Activities conducted by HTI at the facility include purifying spent
refrigerant and returning it to customers. HTI began operations at the site in June 1994. The site property is
approximately 3.01 acres in size.

On April 1, 1999, a failed connection hose to one of HTI's outdoor storage tanks resulted in a spill of
approximately 7,797 pounds of Freon 11 to the ground surface. HTI immediately commenced excavation of
soil impacted by the spill. Over a 10 day period, approximately 400 to 500 cubic yards of contaminated soil
were excavated from the area. Analytical results from soil samples collected from the excavation on April 2
and April 7, 1999, indicated the presence of Freon 11 at elevated concentrations. Freon has also been detected
in a number of wells in the area. The TSC reviewed available information pertaining to the fate and transport
of Freon. The TSC completed a literature review and provided the following:

• Sample Preservation Techniques for VOC's (Freon 11)
• Screening Criteria for Freon 11
• Public Health Goal for Trichlorofluormethane (FC-11) in drinking water
• Ground-water Screening Criteria for Trichlorofluoromethane (Freon 11) and,

The RPM requested that the ESD-LV TSC provide assistance in the measurement of chlorinated organic
isotopes in groundwater to determine possible sources of Volatile Organic Compounds (VOC's) in the
groundwater system.

Liberty Industrial Finishing site located in Farmingdale, NY is an abandoned site covering less than an acre on
a 7 '/2-acre tract of land in an industrial park. From 1948 to 1978, the company carried out electroplating,
-------
dyeing, and painting operations at the site. The contaminated areas consist of three acid vats, a sludge drying
lagoon, two leaching basins, a number of finishing vats, and a basin for holding storm water. In 1977, the State
found Liberty in violation of the discharge limits of its permit. Liberty was ordered to clean up the site in 1978,
but did not do so. As an initial action, the company, under State supervision, removed contaminated soils and
sledges from the leaching basins, the storm water basin, and the sludge lagoon. Groundwater and soils are
contaminated with heavy metals including cadmium and chromium. People who drink water from
contaminated wells may be at risk.

Following a number of conference calls with the RPM the TSC provided information on "isotopic signatures"
via the document titled "Literature Review: Stable Isotopic Signatures for Chloroethane Source and Progress
Identification." The TSC also arranged with the Environmental Isotope Laboratory at the University of
Waterloo to analyze site samples. The TSC prepared the QAPjP which was provided to the Region for review.

special analytical analysis of site samples.

The Reich Farm site is an open, relatively flat, sandy area covering approximately 3 acres in Dover Township,
New Jersey. The site is surrounded by commercial facilities and wooded area. During a 5 month period, the
site was leased from the Reich Farm owners by an independent waste hauler and used illegally for the disposal
of drums containing organic solvents, still bottoms, and residues from the manufacturing of organic chemicals,
plastics and resins. In December 1971, the owners of the property discovered approximately 4,500 drums
containing wastes on a portion of land that they had rented out. These drums bore labels indicating that they
belonged to the Union Carbide Corporation. The TSC has been requested to assist in developing a sampling
plan for soils using "Punch Technology."

The TSC completed a review of site reports and held a conference call with the RPM to clarify the specific
goals of the soil sampling effort. The RPM stated that he wanted a sampling plan that would generate the
appropriate data to determine if the concentrations of "SAN trimer" in the soil column were low enough to
delist the soil at the site. The sampling plan will be completed in six weeks.

The Stanton Cleaners area groundwater contamination site is located in the area of Stanton Cleaners, which is
an active dry cleaning facility located at 110 Cutter Mill Road in a commercial area of Great Neck, Nassau
County, New York. The facility is bordered to the west by Cutter Mill Road, to the north and east by indoor
tennis courts, and to the south by a gasoline station. Due to elevated groundwater levels of PCE, NCDH
ordered Stanton Cleaners to conduct a subsurface soil and groundwater investigation at the site. The site was
referred to NYSDEC in January 1984. As a result of the subsequent investigations conducted at the site, a
plume of contaminated groundwater, consisting primarily of PCE, had been documented to be migrating from
the site. PCE was detected in groundwater samples at concentration exceeding the State and Federal maximum
contaminant level (MCL) of 5 micrograms per liter (ug/L).

-------
Chlorinated solvent contamination was discovered in Municipal Supply Well 1-1 for the town of Vestal in the
late 1970's. EPA Region II conducted a Preliminary Assessment shortly after the contamination of Water-
Supply 1 -1 was discovered. The site scored high enough on the Hazard Ranking System to warrant placement
on the National Priorities List (NPL). Due to the "diesel-like" odor of the liquid phase product, the petroleum
pipeline that the SVE well field straddles was suspected of being a potential source.

Following the review and assessment of provided analytical data the TSC provided the report titled
"Assessment of Chemical Fingerprinting at the Vestal Well 1-1 Superfund Site to the Region. In this report the

The Sharon Steel Corporation Farrell Works Disposal Area (the "site") is an area of about 400 acres located in
Mercer County in Western Pennsylvania, within a few hundred feet of the Ohio/Pennsylvania border. The site
is southwest of the former Sharon Steel Corporation Farrell Works, and is bordered on the east by the Shenango
River. The Sharon Steel Corporation used the area to dispose of blast furnace slag, electric arc furnace slag,
basic oxygen furnace slag, and sludge beginning about 1900. From 1949 to 1981, millions of gallons of spent
pickle liquor acid were dumped over the slag. It was thought that the acid would partially evaporate and then
be neutralized by the carbonates in the slag. In actuality, ground water contamination resulted. The site is
located in the flood plain of the Shenango River, and there are several wetland areas on site.

This on-going effort involves the updating of the PROUCL program such as:

• including test of normal and lognormality
• Small samples - Shapiro Wilk's test/normal probability plot
• Large sample - Kolmogrov-Smirnov's test/normal probability plot, and
• for lognormally distributed data sets, include a 99% Chebychev inequality based upon minimum variance
unbiased estimates. This program plus the "User's Guide Program PROUCL", "Background and a Brief

south of the site is the location of a former wood-preserving plant, Koppers Co., Inc., and is currently listed on
the National Priorities List (NPL). The area east of the site is used for industrial purposes.

At the present time, EPA and the South Carolina Department of Health and Environmental Control (SCDHEC)
are evaluating appropriate cleanup goals for soil arsenic and lead levels that are based on the results of a Human
Health Baseline Risk Assessment. The concentration range for lead should be 895 to 1,150 mg/kg; and the
concentration range for arsenic should be 10 to 37 mg/kg. Once the recommended Phase II soil sampling
strategy has been approved, it will be incorporated into the Phase II Field Sampling Addendum.

The TSC completed and provided to the RPM statistical analysis results for lead and arsenic in site sediments
and soils. A sampling/monitoring approach was developed titled "Statistical Sampling Plan for Phase II
Sampling at Columbia Nitrogen Site Charleston, S.C." that was provided to the Region. The TSC participated
in a number of conversations with the Region pertaining to the Sampling Plan and TSC comments and
suggestions.

The Regional Remedial Project Manager (RPM) requested that the Environmental Sciences Division (ESD-Las
Vegas (ESD-LV) Technology Support Center (TSC) provide assistance in reviewing the PRP's suggested
hydrogeological groundwater remediation approaches.

The 3-acre Distler Brickyard site in West Point, Kentucky is located on a 70-acre abandoned brick
manufacturing plant property that operated from the late 1800s until the mid-1970s. In 1976 the property was
leased by Kentucky Liquid Recycling Inc., which began transporting waste to the brickyard property. Waste
disposal was contained at the site until 1979. There were approximately 2,300 drums on the site, 1,550 of
which contained various liquids, sludges, and solids. Spillage from the deteriorated drums killed grass, trees,
and birds on the site. A contaminated groundwater plume is located beneath the site and could threaten the city
drinking water wells and the Ohio River.

Specific contaminants detected in groundwater and on-site soils include various volatile organic compounds
(VOCs) and heavy metals including lead from waste disposal activities. Potential health threats include direct
contact with, or accidental ingestion of, contaminated soils and groundwater.

The TSC received, and reviewed, three documents pertaining to groundwater remediation. Comments and
recommendations were provided to the RPM. The lead scientist participated in a technical meeting with the
RPM, USGS, and Kentucky State personnel in June. It was agreed at the meeting that additional field data are
required to fully evaluate potential biodegradation at the site. The TSC is to prepare the FSP, and the USGS
will lead the collection of additional field data. TSC will interpret the new field data and make a
recommendation for further remedial action at the site. Distler Brickyard support is expected to continue into
FY 2000 and may include a cooperative effort with USGS, EPA, State of Kentucky for design, construction and
operation of an "enhancement" to the existing remedy. Several conferences calls were conducted with USGS
and the Region to iron out the details of a schedule for the sampling event. Sampling activities at the Distler
site to be conducted by the USGS are scheduled for October 18-22 and will include 11 wells. Samples will be
sent to the EPA Water Quality Laboratory in Athens, Georgia for analysis. Data analysis will be performed by
TSC staff.

The TSC and USGS completed the draft "Field Sampling Plan for the Distler Brickyard". TSC and USGS
prepared a status update on field activities for the RPM. The update discusses the sampling activities
conducted, problems encountered in the field, recommendations for improving site conditions, and a
preliminary schedule for completion of the final report. A conference call was held to finalize this report with
Femi Akindele. The TSC completed and delivered the report titled "October 1999 Groundwater Sampling and
Data Analysis Distler's Brickyard, Hardin County, Kentrucky".
20
-------
The TSC provided the following documents to the Region: "Final Field Sampling Plan" and "Proposed
Activities for Fine Grained Alluvium (FGA) Sampling." Following the collection and analysis of site samples
and data the TSC provided the report titled "Summary of Groundwater and Soil Gas Collected June-August,
2000 Distler Brickyard Superfund Site, Kentucky." A meeting with the RPM occurred on October 11, 2000 at
the Regional Office and at this meeting presented the results obtained from groundwater and soil gas sampling
activities conducted at the site June-August 2000. Possible final remedial response actions were presented to
EPA, however, a final decision for the site was deferred pending completion of the final report.

The report titled "June-August 2000 Groundwater and Soil Gas Data Analysis, Distler Brickyard Site,
Hardin County, Kentucky" was completed on November 30, 2000. This report recommended the investigation
of an innovative enhanced bio-remediation technology for remediation of remaining chloroethene
contamination at the site. Conference calls were conducted in January and March 2001 with USGS, EPA, and
the State of Kentucky to discuss TSC recommendations.

recommending an improved remedial strategy.

The 9-acre Distler Farm site in Louisville, Kentucky was discovered in 1977 when the EPA launched a search
for sites previously used to store industrial wastes. In 1978, flood waters scattered drums of industrial waste
stored at the site along the flood plain of Stump Gap Creek. In an emergency cleanup action, the EPA
recovered and repacked 832 drums containing chemicals characteristic of the paint and varnish industry and
then moved them to higher ground. The primary contaminants of concern affecting groundwater and soils are
VOCs including TCE and PCE, metals and inorganics.

by the RPM in which the TSC would participate:
22
-------
1. Review of the initial groundwater data and the groundwater monitoring plan.

2. Review of the PRPs's proposal for MNA and

3. Review groundwater data reports.

The Shuron Inc. Superfund Site is located in Barnwell County, South Carolina. The site property consists of 85
acres, and slopes slightly from north to the southeast. The main building, from which lens manufacturing
operations were conducted, is situated on a 34-acre portion of the site property. Approximately fifty-one
additional acres, designated primarily as wetlands, lie to the east and southeast of the main building. The site
was used by Textron, Inc. (from 1960 until 1985) and Shuron, Inc. (1995 until 1991) as an ocular lens
manufacturing facility.

Wastewater generated from manufacturing processes conducted on the site contained volatile organic
compounds (VOCs), semivolatile organic compounds (SVOCs) and metals. Wastewater was discharged from
the main building to the wastewater settling lagoons, which lie east of the building. Wastewater from the
settling lagoons was discharged to the northern drainage ditch, which drained to the wetland, east of the main
building. Sediment from the lagoons was transferred to the solids ponds located south of the settling lagoons.

At the request of the RPM, two TSC scientists met at the site in April 2000. The TSC reviewed the RJ report,
the ROD, and the baseline groundwater report and provided comments in the letter report titled "Review of the

unknown volatile and semi-volatile compounds (TICs) in ground water samples.

The 30-acre Tower Chemical Company site located in Clermont, Florida is an abandoned chemical
manufacturing facility. During its operation, TCC owned and used two separate parcels of land; a main facility
and an irrigation field. From 1957 to 1981, TCC manufactured, produced, and stored various pesticides. TCC
discharged acidic waste waters produced in the main facility into a '/2-acre, unlined percolation/evaporation
pond where contaminants were solidified. TCC burned and buried the waste on a 1 !/2- acre plot located at the
main facility. In 1980, the waste eater pond at the main facility overflowed into an adjacent swamp and entered
an unnamed stream north of the site.

The TSC is currently reviewing site analytical data.

The RPM requested that the ESD-LV TSC provide assistance in identifying geophysical techniques that could
be used to identify the location and magnitude of buried drums in a landfill.

The Wingate Road Municipal Incinerator Dump covers 61 acres in Fort Lauderdale. The site includes an
incinerator, office, and a 40-acre disposal area, all owned and operated by the City of Fort Lauderdale. The
incinerator and disposal areas were used from 1955 to 1978. Residential waste, commercial waste, and
incinerator residue were disposed of at the dump. The facility received 480 tons of waste a day and operated 7
days a week. The soil and subsurface soil are contaminated with pesticides including DDT, aldrin, and
chlordane from former waste disposal practices at the site. Direct contact with, or accidental ingestion of the
contaminated soil from the area of the hazardous substances could pose a potential health threat.

Following an assessment of provided site data the TSC prepared the report titled "Recommendations for Non-
Invasive Investigation to Search for Buried Drums". The PRP's have settled all issues at the Wingate site and
are now ready to begin closure of the landfill. The TSC provided additional recommendations for a non-
invasive drum search involving geophysics. A site visit by the TSC was completed. The geophysical survey
was conducted by Glen Carpenter of Sage Earth Sciences Corporation. A geophysical report titled "Magnetic

The RPM requested that the BSD, TSC provide assistance in evaluating the use of the USEPA VLEACH model
in determining the amount of soil that should be removed.

The Detroit Arsenal Tank Plant (DATP) site is a 153-acre industrial section of the Detroit Arsenal in Warren,
MI. Originally built by the Army and owned by Chrysler in 1940, the "Arsenal of Democracy" was one of the
two government-owned, contractor-operated battle tank manufacturing plants in the U. S. DATP was operated
by General Dynamics Corp.(GD) until December 1996; GD still operates another tank plant in Lima, Ohio.
The remaining non-BRAC part of the Arsenal is occupied by the Tank-Automotive Command (TACOM), the
R&D command for all army land vehicles.

The most significant response action at DATP is a time-critical removal, started over one year ago, of a former
solvent and paint waste dump in the West Test Track infield (in Army vernacular, the "Metal Debris Disposal
Area) although the only metal found so far has been several hundred 55-gallon drums). To date over 15,000
cubic yards of TCE-contaminated soil have been removed and hauled off-site for treatment and disposal.

25
-------
Although the original waste source has been removed, considerable TCE and vinyl chloride contamination
remains, which threatens a potable sand aquifer located 80 feet BLS.

A preliminary review of the documentation for the DATP, Metal Debris Disposal Area (MDDA) was
performed to answer questions regarding the appropriateness of using the EPA VLEACH model for
determining a preliminary remediation goal (PRO). Preliminary indications are that the model is not
appropriate. The model is a vadose zone model and is being applied in what appears to be a saturated
environment. In addition, substantive concerns have been identified regarding proper application of the model.
This information was communicated during several telephone calls this week with the RPM along with requests
for additional information. The Army is currently in the middle of a final removal action based on the model
results and expects to be done before a possible final Base Closing Team (BCT) meeting scheduled for late
September. A more thorough review of the model/modeling was completed with formal comments transmitted
to the RPM. The comments were then forwarded to the Army BRAC Environmental Coordinator. The TSC
responded to a number of comments and recommendations that were suggested by the PRP's. The TSC
received a work plan addendum from DoD. The TSC reviewed the work plan addendum and provided
comments to the Region.

The TSC reviewed the "Draft Closure Report" and the "Technical Memorandum: Calculation of PRG's for
Soil at the MDDA Detroit Arsenal Tank Plant, Warren, Michigan" and sent comments to the Region. This
review utilized the following provided documents as reference material: 1) Draft Remedial Action Work Plam,
Rev 2, West Infield Disposal Areas, 2) Site-Wide Decision Document/Remedial Action Plan, and 3) Draft
Closure Plan, Metal Debris Disposal Area (2 volumes). The TSC participated in a number of discussions with
the Region pertaining to the future and status of this site. It appears that this site may come under the RCRA
Program.

The RPM requested that the ESD-LV TSC provide assistance in reviewing a proposed modification to SW-846
Method 8330 for explosives analysis.

The Joliet Army Ammunition Plant covers 14 square miles of an inactive munitions facility in Joliet, IL. The
site consists of two areas: the manufacturing area that produced constituent chemicals and explosive materials,
and the Load-Assembly-Packing Area, which is listed as a separate site on the National Priorities List. More
than 4 billion pounds of explosives were produced in the manufacturing area from the early 1940's until 1977.
During the manufacturing process, contaminated process waters and chemical spills were routinely discharged
without treatment into constructed drainage ditches, where they flowed into Jackson Creek and Grant Creek.
26
-------
Unlined piles of incinerator ash and a leak in the liner of one of several wastewater lagoons have also
contributed to contamination of groundwater and surface water.

The TSC reviewed the proposed modification and supporting laboratory data and provided the Region with the
reports titled "Review and Recommendations for Proposed Modifications to Method 8330" and "Review of
Modified SOP for Explosives Analysis, Joliet Army Ammunition Plant."

The RPM requested that the ESD-LV TSC provide assistance in designing a sampling/monitoring plan for a
residential area near the site.

This 13-acre site(formerly known as Northwestern Barrel) is located in South Milwaukee, Milwaukee County,
Wisconsin. The site is a former drum recycling facility which operated from 1941 to 1964. While in operation,
residual wastes from the drum cleaning operation were placed in disposal pits on the eastern portion of the
property. These wastes included paints, oils, grease, dyes, and other chemicals. The lake bluff on the eastern
side of the property and the ravine on the northern side of the property were also impacted during drum
cleaning activities.

In late 1964, U.S. EPA conducted a site assessment which revealed the presence of metals, polychlorinated
biphenyls (PCBs), and the volatile organic compounds (VOCs) on the site. In 1955, U.S. EPA issued an order
to numerous companies suspected of sending drums to the site and to Towne Realty, as the owner of the site.
The order required the removal of the contents in the on-site disposal pits and additional testing.

Following the review of site data and documents the TSC provided the Region with a sampling/monitoring
design for the site. Following a review of the "Sampling/Monitoring Design" report by the RPM, the TSC
provided the Region with a revised approach titled "Sampling Approach for Residential Properties Associated
with the Marina Cliffs/Northwest Barrel Site." The TSC participated in a number of conference calls with the
Region pertaining to TSC comments and suggestions.

The RPM requested that the ESD-LV TSC provide assistance in reviewing a request by the PRP's to expand the
capacity of the chemical waste landfill.

The Wayne Disposal site in Wayne County, MI. has been accepting wastes for a number of years. The
currently operating disposal cell contains both a leak detection and leachate removal system as well as primary
and secondary barriers/liners. The cell is constructed within a clay pan (glacial till) formation. Underlying the
clay pan is a silt aquitard which is underlain by a sand aquifer of considerable extent.

During the permit application process, questions arose relating to the site hydrology. Specifically, questions
arose regarding the role of an underlying clay layer in the hydrologic isolation of the disposal unit in question,
and whether the area around the disposal site constitutes a ground-water recharge zone.

The TSC previously participated in a technical peer review panel to address various issues. The TSC received a
number of documents to review. The review of provided data and information was completed. The TSC
provided the Region with the report titled "Assessment of the Natural Clay Beneath Master Cell V and the
Campsite Liner System for the Proposed Expansion of Master Cell VI."

The RPM requested that the ESD, TSC provide assistance in reviewing site documents and possible modeling
subsurface contaminants.

The area around this 0.75-acre site, located in Houston, Texas, is a mix of residential, commercial, and light
industrial facilities. Approximately 2,000 residents and 100,000 other people move within a one-mile radius of
the site on a daily basis due to recreational activities associated with the area. The site operated as an electrical
transformer salvage and recycling company between 1971 and 1978, and as a chemical recycling and supply
company from 1979 through 1980. The first documented investigation of this site took place during the fall of
1971 when the City of Houston Water Pollution Control Division noted that the workers at Industrial
Transformers poured oil out of electrical transformers onto the ground during transformer dismantling.

A technical assessment of the site, commencing in January 1986, indicated the presence of PCB contamination
has been confined to the top two feet of soil. The highest concentrations of PCBs were found in the middle of
the site. TCE has migrated deeper than the PCBs and away from the site. Residual TCE remaining in the
surface soil will be remediated along with the PCB contaminated soils.

The TSC reviewed a number of documents and provided initial comments and recommendations to the RPM.
TSC personnel met with the RPM, and the State of Texas staff in Houston, TX for a site visit and a more
definitive discussion as to what assistance the TSC will provide. Following the site visit, the TSC provided a
list of technologies that may be useful at the Sol Lynn site and provided information about dissolved oxygen
(DO) measurements. The TSC reviewed and provided comments on the amended work plan in particular to the
fate and transport modeling issues. The TSC reviewed and provided comments and suggestions pertaining to
the "Supplemental RI/FS Study" and provided information on the required groundwater modeling parameters.
In addition, the TSC received, and reviewed, the "Field Sampling and the Data Management Plans." The TSC
is currently doing the sub-surface modeling for the Region. Additional data (i.e., well survey and water level
data) was received by the TSC and is being used to update the preliminary groundwater flow model.

The RPM requested that the ESD-LV TSC provide assistance in reviewing a natural attenuation report.

This 66-acre site located in Houston, Texas is a mixture of residential, commercial, and industrial properties.
The site was used as a wood preserving and coal tar distillation facility from 1910 to 1962. The wood
30
-------
preserving facility consisted of an operation area, a drip track, and treated and untreated wood storage areas.
The operation area included wood-treating cylinders, chemical storage tanks, and a waste water lagoon.
Creosote and metallic salts were used in the operation.

The primary contaminants of concern affecting the groundwater, soil and sediment are VOCs including
benzene, toluene, and xylene, other organics including PAHs; and metals including arsenic, chromium and lead.

The TSC received, and is currently reviewing, the report "Verification of Groundwater Fate and Transport
Evaluation" dated July 2000. The TSC is also reviewing comments by Roger Lee on the "verification" report.
In November the TSC provided the Region with a report titled "Review of Verification of Groundwater Fate
and Transport Evaluation-South Cavalcade Superfund Site, Houston, Texas." In summary, source control or
removal is usually a prerequisite for selection of MNA. Creosote present as a DNAPL at this site would be
expected to persist for decades or longer. Therefore, the plans for removal or long term management of this
material are an important part of a remedy, but are not addressed in this document. The TSC participated in a
number of conference calls with the Region pertaining to TSC comments and recommendations.

The RPM requested that the ESD-LV TSC provide assistance in modeling ground deposition rates relative to
air contaminant concentrations

The Asarco Omaha facility refined lead bullion and lead drosses. Refinement was achieved using traditional
pyrometallurgical processes including addition of metallic and non-metallic compounds to molten lead to
remove impurities. The Omaha plant produces refined lead and speciality metal by-products including
antimony-rich lead, bismuth, dore' (silver-rich material) and antimony oxide. Although fundamentally
classified as a primary lead refinery (not lead smelter), the Omaha plant is the only facility in the United States,
and one of only a few such facilities in the world, designed to process lead bullion containing recoverable
amounts of several different metals. As a result, the facility employs a complex array of both traditional and
unique pyrometallurgical processes which are carried out as batch operations. This facility was constructed in
the early 1870s and is currently closed.

The TSC review of site and metallurgical data deposition was completed. Following this review an initial
model was completed. This model included plots of relative annual wet and dry deposition rates from the 180'
"Black Stack" covering the periods 1984 through 1990. Deposition modeling runs have been completed for the
180' stack. A 310' stack is soon to be evaluated. Once all the modeling is completed, a report will be written
and provided to the Region. The final report "Dispersion Modeling of Atmospheric Deposition Patters Around
the Asarco Omaha Lead Refinery" was completed and sent to the RPM. This report details the methods and
results of lead fallout modeling for both the 180-ft. Black Stack and an old 310-ft. Stack. There was some
follow-up work completed comparing the modeling results with a map of actual soil concentrations. Comments
pertaining to the comparison of soil concentration with the modeling results were provided to the RPM. The
TSC was requested to provide geostatistical support by kriging soil lead concentrations on and in the vicinity of
the smelter. The TSC completed the kriging and provided maps and associated overlays. In addition, the TSC
provided recommendations for additional sampling locations that would improve the kriged results. Based on
these maps the RPM requested assistance in identifying specific sampling locations. The TSC provided the
Region an "all properties kriged map identifying six locations where additional samples should be collected."
The TSC provided the Region with a table identifying properties on and near the site that exceeded 400 mg/kg
of soil lead at one mile increments. Also provided were maps showing actual property locations.

The Big River Mine Tailings site in Desolge, St. Francois County, Missouri, was used for disposal of lead mine
tailings during 1929-58. The site a former mining region about 70 miles south of St. Louis is often referred to
as the "Old Lead Belt". The region (approximately 110 square miles) contains numerous tailings ponds and
piles.

St. Joe Minerals Corporation operated the site. There is disposed lead, cadmium, and zinc rich mine tailings
over approximately 600 acres in rural areas bordered on three sides by Big River. In 1972, the company
donated 502 acres of the land to St. Francois County, which then leased the land to St. Francois County
Environmental Corp. (SFCEC). Since 1973, SFCEC has operated a sanitary landfill on approximately 60 acres
of the southern section of the tailings pile.

EPA learned of the site in 1977, when an estimated 50,000 cubic yards of tailings slumped into the Big River
during a heavy rain storm. After the collapse, the Missouri Department of Conservation detected elevated lead
levels in bottom-feeding fish and advised local residents.

The RPM requested the TSC to evaluate and identify air deposition of lead-containing particulates in the
vicinity of mine waste piles. The deposition of particulates were modeled to determine if additional sampling is
required to characterize lead contamination. In addition, samples from this site will be analyzed to determine
the amount of total and bioavailable lead for risk assessment purposes.

Source emission modeling was completed for 34 chat pile and tailings flat sources utilizing over six years of
hourly wind data. These emission rates accounted for source-specific particle size, surface roughness, pile
height, and lead concentration. Air dispersion modeling using the Fugitive Dust Model has been completed for
all sources over a coarse receptor grid of the entire 225 km 2 region. All deposition modeling has been
completed and the report "Air Dispersion Modeling of Mine Waste in the Southeast Missouri Old Lead Belt"
was given to the Region. The report was reviewed by the Region and the Agency for Toxic Substances and
Disease Registry. The report was finalized and developed into an external report and a journal manuscript. The
final publications will include a comparison of the modeling results with surface soil sampling data recently
obtained. Initial examination of these sampling results indicate very good agreement with model predictions.
Finalization of the modeling report was completed, after receiving review comments from the RPM. Review
comments were received. The report was finalized. The RPM requested that the TSC provide assistance as
needed to the PRP sub-contractor (TRC, Inc.) in using modeling results for the PRP's current site assessment.
This benefits EPA by promoting consistency and coordination between the PRP and EPA's site assessment
methods and assumptions. On September 29lh, Gayle Hoffnagle of TRC Inc., was sent a zipped file containing
the six 1-year St. Louis FDM met files that were used in the Big River site modeling and an Excel file
containing Desloge air monitoring (lead only) data that was built from hard copies of Shell monitoring reports.
The TSC Task Lead and the TRC Inc. personnel have had a number of discussions pertaining to a number of
modeling issues.

-------
The TSC received a request to review a Deposition Sampling Protocol developed by the PRP subcontractor,
TRC. That protocol proposed that downwind deposition of wind suspended lead be measured using oil-coated
filters in samplers located downwind of two tailing sites. The TSC completed the review of the deposition
sampling protocol and provided comments to the Region. In December the TSC was requested to review a
new air sampling plan submitted by TRC. The plan was reviewed with comments and suggestions provided to
the Region. The TSC completed some lead/soil analysis and provided the Region with the report titled "Big
River Superfund Site In Vitro Soil Extraction."

The Cherokee County site is a mining area covering about 110 square miles. It is part of a larger area
sometimes called the Tri-State Mining District, which encompasses Cherokee County in Kansas, Jaspar County
in Missouri, and Ottawa County in Oklahoma. One hundred years of widespread lead and zinc mining created
piles of mine tailings, covering 4000 acres in southeastern Cherokee County alone. The mine tailings
containing lead, zinc, and cadmium, have leached into the shallow groundwater. Runoff from the waste piles
also has moved contaminants into nearby streams. The Regional OSC requested the use of BSD TSC's X-Ray
Fluorescence technology and equipment to measure site contaminants. The BSD TSC supported this effort.
The RPM requested special analytical support. The TSC analyzed a number of samples collected from this site
to determine the amount of total and bioavailable lead for risk assessment purposes. A data report was
provided to the RPM.

The TSC also reviewed the "In Vitro Analytical Method" and provided comments to the Region. The TSC
participated in the "Vitro Bioaccessibility Method Validation Study". The analytical results of this effort were
provided to the Region. In addition, the report titled "In-Vitro Test Method -Addendum Level IV Report" was
finalized. The TSC prepared for the second round of "In-Vitro Analysis" which consisted of approximately 80
samples. Following sample preparation, the sample extracts were submitted for laboratory analysis. The
samples were analyzed. The resultant data was evaluated for data quality and provided to the RPM and Ms.
Goldade of ISSI. The TSC is waiting for the final report. The TSC was requested to extract and analyze some
additional samples. The samples were extracted and sent to a laboratory for analysis. Laboratory analysis was
completed and the results were provided to the Region in the report "Big River Superfund Site In Vitro Soil

The RPM requested that the BSD, TSC provide assistance in the in-vitro analysis of soil samples that are part of
a treatability study being conducted by the Region.

The Oronog-Duenweg Mining Belt site, which covers 6,400 acres, is considered part of the Tri-State Mining
District of Missouri, Kansas, and Oklahoma. Two other sites in the district, Cherokee County in Kansas and
Tar Creek in Oklahoma, were placed on the NPL in 1983. Lead and zinc ores, as well as some cadmium ores,
were mined from 1948, to the late 1960's, with the greatest activity occurring in an area between Oronogo and
Duenweg northeast of Joplin.

Mining efforts were originally performed by independent operations that, in later years, were organized by
several area mining companies. The site is honeycombed with underground workings, pits, shafts (open,
closed, and collapsed), mine tailings, waste piles, and ponds holding tailing waters, An estimated 10 million
tons of wastes or tailings are on the site.

Tests conducted in 1977 by the U. S. Geological Survey found On-site groundwater and surface water to be
contaminated with heavy metals including lead, zinc, and cadmium from the mining operations. Potential risks
may exist through drinking contaminated surface water and groundwater or coming into direct contact with
contaminated water.

The TSC received and reviewed the work plan titled "Phosphate Stabilization of Heavy Metals-Contaminated
Mine Waste Yard Soils, Joplin, Missouri NPL Site". Comments were provided to the RPM. The analytical
QAPjP was reviewed. Comments were provided to the RPM. The samples for this in-vitro analysis are

The RPM requested that the ESD-LV TSC provide assistance in reviewing a QAPjP that will be utilized by
DoD for characterizing site contaminants.

The Schilling (SAFE) site is located in Salina, Kansas and is the former location of a military air base that
encompassed over 4,000 acres and operated from 1942 to 1967. Previous analyses of surface soil, subsurface
soil, ground water, surface water and sediment samples have shown elevated concentrations of various
contaminants, including volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and
metals at numerous locations throughout the former SAFE. Results of past investigations indicate that the
greatest threat to human health and the environment is posed by VOC contamination in ground water. An on-
going remedial investigation (RI) by the Unites States Army Corps of Engineers (USAGE) is focused primarily
on an extensive trichloroethyene (TSE) plume that appears to be situated in the northeastern portion of the
former base property.

The TSC completed the review of the QAPjP and provided the Region comments and recommendations in the
report titled "Review of the Draft Quality Assurance Project Plan for Expanded Site Inspection at the Schilling

Mr. D. Bell, Federal Facilities Restoration and Reuse Office (FFRRO), EPA requested the TSC, NERL, ESD-
LV assistance of statisticians in reviewing the Unexploded Ordnance (UXO) Statistical Sampling
(SiteStats/Grid Stats) and Risk Assessment (OECert) Methodology developed by QuantiTech, Inc., for the U. S.
Army Engineering and Support Center, Huntsville (USAESCH), Alabama. These procedures were developed
for conducting engineering evaluation/cost analysis (EE/CA), and UXO investigations for various ordnance and
explosives (OE) located on Formerly Used Defense Sites (FUDS). Three statisticians, Dr's Max Englehardt.
Ashok K. Singh, and Anita Singh, were asked by the TSC to review and assess provided documents and
computer programs.

Lowry Field included an airfield and a bombing and gunnery ranges comprising 65,547 acres of Arapahoe
County, CO near the town of Aurora. The airfield and bombing range were used by the Army during World
War II for bombing practice and high explosive bombs, and fixed and flexible gunnery targets. After World
War II, the airfield became a Naval Air Station; the bombing range came under the custody of Lowry Air Force
36
-------
Base, and was known subsequently as the Lowry Bombing and Gunnery Range. The Air Force continued to
use the bombing range, and added a demolition range at the west end of the bombing range, and later also
created the Lowry Training Annex. Ordnance found at the site indicated that Lowry Air Force Base used the
range in support of its air photography mission. A portion of the range was used for training support during the
Vietnam War. Four Titan missile sites were also constructed on the bombing range. The TSC reviewed the
provided site documents and data and then developed a data base for unexploded (UXO) data assessment(s).

The RPM requested that the ESD-LV TSC provide assistance in plutonium and americium performance
evaluation standards.

This site is located about 20 miles southeast of downtown Denver, Colorado, in unincorporated Arapahoe
County. From the mid-1960s until 1980, the site was operated as an industrial liquid waste and municipal solid
waste landfill. Liquid wastes disposed of at the site included hazardous substances such as VOCs and heavy
metals. In 1980, waste disposal was restricted to municipal solid waste. In 1984, the site was placed on the
National Priorities List (NPL). From 1984 to 1993, studies were performed to define the nature and extent of
contamination, to estimate potential health and environmental risks, and to evaluate cleanup alternatives for the
site.

The TSC reviewed site data and the proposed sampling/analysis plan. Information concerning descriptive
laboratory detection levels were also received and reviewed. The TSC discussed the proposed PE sampling
plan with the RPM. The analytical labs sent sample bottles. The TSC spiked the bottles with AM-241 and

The Regional TPO requested that the ESD-LV TSC provide assistance in auditing GC and GC/MS laboratory
data, and to provide analytical protocol assessments.

The Aerojet General Corp. covers 8,500 acres near Rancho Cordova, 15 miles east of Sacramento. Since 1953,
Aerojet and its subsidiaries have manufactured liquid and solid propellant rocket engines for military and
commercial applications and have formulated a number of chemicals, including rocket propellant agents,
agricultural, pharmaceutical, and other industrial chemicals. In addition, the Cordova Chemical Company
operated a chemical manufacturing facility on the Aerojet complex from 1973 to 1979. Both companies
disposed of unknown quantities of hazardous waste chemicals, including TCE and other chemicals associated
with rocket propellants, as well as various chemical processing wastes.

The initial effort by the TSC was to identify the contents of the provided tapes and disks. Following an
assessment of the tapes and disks a letter report describing the contents was provided to the Region. Due to
missing data the data audit was discontinued. The TPO then requested the TSC to provide available
information pertaining to hydrazine in water. The TSC provided the Region with a report titled
"Considerations on the Handling and Storage of Aqueous Samples to be Analyzed for Hydrazine". Additional
assessment of Aerojet analytical protocols was accomplished. A report providing an assessment of perchlorate,
hydrazine, and NDMA analytical protocols was provided to the Region. The TSC provided the RPM an
assessment of 49 analytical SOPs that are being used to analyze samples. The TSC reviewed a revised SOP for
hydrazine to identify inadequacies, determine if appropriate methods are being used, and to verify consistency
with EPA and state guidance. Following the fmalization of all SOP's by the PRP, the RPM requested the TSC

The Regional RPM requested that the ESD-LV TSC provide assistance in evaluating and identifying
appropriate air sampling methods that could be implemented that would provide data to determine the exposure
of contaminants to off-site residents.

The site, located in Yerington, NV, was undeveloped before 1951. Mining operations started at the site in
1953. In 1978, Anaconda (owned by ARCO) closed down the mining and milling operation. In 1978, portions
of the site were sold to Unison, a transformer salvaging company. In 1988 the entire property was sold to
Arimetco Inc. who operated at the site until early 1999.

During a conference call with the RPM the TSC described potential modeling approaches and described similar
modeling work done for a Superfund site in Region VII (Desloge, Old Lead Belt, Missouri). The TSC provided
background document references to the RPM and mailed a copy of the INEEL report on Old Lead Belt
Modeling. The TSC also provided information pertaining to sampling to determine whether a particle size
analysis (mode of the aggregate size distribution) of existing soil samples from the site would be useful for
determining modeling input (threshold friction velocity for particle suspension.) The TSC has had a number of

The RPM requested that the ESD-LV TSC provide assistance in reviewing ambient air monitoring and
monitoring plans.

This 213-acre site operated as a landfill between 1957 and 1979, during which about 9 million cubic yards of
municipal refuse, solid and liquid industrial wastes, and some medical wastes were deposited. However, the
site was closed in 1979 due to the threat of flooding from the Salt River Channel. This remedial action is
designed to mitigate threats resulting from flooding. The primary contaminants of concern in the soil/refuse
include VOCs such as toluene and xylenes.

The TSC received three documents for review: The Ambient Air Monitoring Plan and two Ambient Air
Monitoring reports. Following the review it was felt that the four landfill air sampling tests were well
conducted and diat the results showed differential concentrations that were well below levels of concern.
However, the number of samples (total of 8 events per cell) was not adequate to draw the conclusion that long-
term VOC emissions from the landfill are of no concern. The sampling experimental design (discrete 4-hour
upwind/downwind samples) has two inherent and compounding limitations that cannot be overcome with a
limited number of samples: 1) the inability to distinguish source emissions from the relatively high background
concentrations in the area and 2) the dilution of source emissions to below instrument detection limits because
of air transport/dispersion to the downwind samplers. Some additional sampling was recommended.

The TSC received a request from the RPM in early August for information on Open Path Fourier Transform
Infrared Spectrometry (FTR), and whether it could be a useful tool at the landfill. The TSC responded on
August 17 with some background information on the technology and some experience at the INEEL using this
technology. The TSC believes that this technology would be a useful tool to address the landfill issues. The
TSC received volumes 1 and 2 of the Ambient Air Monitoring Program Report and the Ambient Air
Monitoring Plan for review. The review of these documents was completed and the report titled "INEEL

The RPM requested that the ESD-LV TSC provide assistance in reviewing the Unexploded Ordnance (UXO)
Statistical Sampling (SiteStats/GridStats) and Risk Assessment (QECert) Methodology. These programs were
developed for conducting engineering evaluation/cost analysis (EE/CA), and UXO investigation for various
ordnance and explosives (OE) located on Formerly Used Defense Sites (FUDS). Three statisticians, Dr's Max
Engelhardt, Ashok K. Singh, and Anita Singh, were asked by the TSC to review and assess provided document
and computer programs.

The Fort Ord site, located in Marina, CA., was established by the U. S. Army as a maneuver area and field
artillery target zone. Chemicals and hazardous wastes are stored at on-site facilities before they are transported
and disposed of off-site. There are several areas of contamination on sites. One of these areas includes three
inactive landfills that once were used to dispose of residential and commercial waste, In addition to UXO the
facility has leaking hazardous waste tanks, containers of waste oil and various automotive chemicals and
chemical storage areas.

The primary focus of this evaluation will be to conduct an assessment of "SiteStats/GridStats" and OECert that
are used to characterize sites contaminated with UXO. There are questions pertaining to the proper use and
application of the mathematical and statistical approaches that have been incorporated in these programs. The
data for this assessment was provided by the USAGE in Huntsville, Alabama. The TSC completed a report
titled "UXO Sampling and Characterization Using Indicator Kriging an Alternative Approach for Estimating
Probabilities of Finding UXO Item." This report provided to the Region utilized Fort Ord and Buckley Field
data. The TSC also provided the Region with the document titled "Review of the ORNL/TM-13588 Report."
Following additional reviews the TSC provided the following two reports: "Summary of Recent Results on Site
Stats Evaluation Performed After the August 9-10, 2000, Partnership Meeting Between USACE and EPA

The Regional Technical Project Officer (TPO) requested that the ESD-LV TSC provide assistance in auditing
laboratory data.

Located in Cloverdale, California this 5-acre site includes an automotive brake casting plant, a paved area
surrounding the plant, and an open field. Land use in the area is mixed residential/agricultural/industrial. From
1965 to 1972, wastewater containing PCBs was discharged on the site property. Wastewater containing
ethylene glycol was disposed of on-site from 1972 to 1981. The ethylene glycol acted as a co-solvent with
water, and facilitated the transport of PCBs in the soil. About 13,510 cubic yards of soil is contaminated with
PCBs at concentrations up to 4500ppm. VOCs have also been detected in groundwater; however, the source of
this contamination is unknown. The primary contaminants of concern affected soil, sediments, and surface
water are VOCs including TCE and benzene. The primary contaminants affecting groundwater are PCBs.

The TSC received from the Region and Regional IG's office a number of CD-ROMs's and diskettes containing
laboratory data. The TSC has reviewed a number of these data files for questionable manual integrations. A
42
-------
number of memorandums documenting these suspect files have been provided to the Region. The TSC
developed a method file for auditing laboratory analytical data and responded to questions about types and
numbers of files that were reviewed in order to match missing file requests to specific laboratories. The TSC
also received two additional CD's of data which were not included in the original data package. The TSC
completed an initial assessment of the two CD's. The status of this assessment was provided to the Region.
Completing this data audit required "target" software. All data received (i.e. CD's) was sent to Region VI
because the TSC did not have the "Target" software. Region VI failed to complete the audit so the data was
sent back to the TSC. The TSC purchased the "Target" software and was trained on the use of this software.
The TSC conducted data audits and provided the Region with the reports titled "Assessment of Electronic Data

The RPM requested that the ESD-LV TSC provide assistance in evaluating a soil gas monitoring effort by the
PPvP's and assistance in characterizing site organic contaminants. The RPM has requested that costs per OU-1,
OU-2 and OU3 be documented. As shown above total cost and cost per OU are identified.

This Phoenix, Arizona site is located in a mixed residential/commercial area, and is used as a manufacturing
facility. The manufacturing operations required the use of solvents. Underground storage tanks were
discovered to be leaking, which resulted in groundwater and soil contamination both on-and off-site. The
selected remedy for this operable unit addresses groundwater contamination. The primary contaminant of
concern is TCA.

Operable Unit Two is an area of contaminated groundwater down gradient of Operable Unit One. The selected
remedy is an interim remedy designed to address groundwater that is contaminated with volatile organic
compounds (VOCs). The major components of this remedy consist of extraction of groundwater in the vicinity
of Interstate 10 and Van Buren Street, treatment of extracted water near extraction locations by either air
stripping with off-gas treatment by synthetic resin adsorption, or advanced oxidation based on final design
considerations, and injection of treated water back into the aquifer in locations allowing additional control of
the contaminant plume. The TSC reviewed a number of site documents and provided comments.

The existing data presented in site reports were of high quality but several significant data gaps were identified.
Recommendations were made for installation of at least two new groundwater monitoring wells with soil gas
ports. A peer reviewed paper Design, Installation, and Uses of Combination Ground Water and Gas Sampling
Wells (Hubble, Wood , and Higgs, 1998) published by INEEL scientists was provided as a recommendation to
assist in collection of soil gas data with installation of new groundwater wells.

The TSC provided review comments on The Soil Vapor Extraction System Evaluation Report. The
Environmental Restoration Directorate Sample Management Office reviewed the L&V reports supplied as
44
-------
Appendix B-H. While some discrepancies were noted in laboratory technique, the data were validated for use
in evaluating the effectiveness of the Soil Vapor Extraction System (SVE). An independent technical
memorandum produced by Colder Associates (GA) was also reviewed. The GA evaluation methodology was
appropriate and the conclusion that the SVE system achieved the goals of the project was confirmed. It was
noted however that the confirmation sampling was conducted just a few days after shutdown of the extraction
system which did not allow sufficient time for contaminant concentration rebound. The recommendation was
to conduct additional sampling to confirm the initial results.

The TSC provided the Region with comments and recommendations pertaining to the 52nd Street soil gas data
analysis. The TSC received a CD Rom of scanned site documents related to soil investigations and hard copies
of related items. The purpose of the document review is to provide assistance in determining the sufficiency of
site characterization at the site and beyond the CY and SWPL areas, and whether it is likely that further soils or
groundwater cleanup will be necessary. The TSC is currently reviewing the site documents and will identify
gaps as they are encountered. The TSC received the document titled "Characterization of Inorganic
Constituents in Groundwater, 52nd Street Superfund Site for Motorola, Inc. dated July 1999 for review.

Two modeling reports were received. The first report entitled "Preliminary Review of Groundwater Flow
Models at the Motorola 52nd Street Superfund Site" and the second report titled "Summary of Preliminary
Groundwater Flow and Contaminant Transport Simulations." Those reports were both prepared by the
Hydrodynamic Group (HG) and present reviews of previous modeling efforts plus a description of a new model
that HG prepared to help answer some questions on the potential effectiveness of a proposed pump and treat
remedy. There were some valuable discussions, recommendations, and insights in the reports, but there were
also some shortcomings and issues that need to be resolved. The TSC briefly outlines an approach for
correcting major deficiencies and resolving problems. Ron Araett provided written review comments in a
report entitled ""Review of Two Groundwater Flow and Contaminant Transport Model Reports for Motorola
52nd Street Superfund Site, Phoenix, Arizona, which was transmitted to Nadia Hollan.

The TSC received six additional documents for review. A review of these documents is in progress. The TSC
also participated in a conference call with the RPM and the Arizona State Attorney Generals Office. The TSC
reviewed ADEQ calculations pertaining to soil vapor extraction mass removal analysis and provided some
recalculations. The TSC also provided the following documents to the RPM: "Review of Summary of
Preliminary CVGroundwater Flow and Contaminant Transport Simulations Reports for OU-2 System Phoenix,
AZ. Draft Version 2.0" dated August 2000 and "Review of Revised Groundwater Modeling Report on the
Motorola/Honeywell OU-2 System Superfund Site" dated August 2000. The TSC also participated in a number
of conference calls and meetings in San Francisco and Phoenix, AZ. TSC representatives attended a Honeywell
site review 20-24 October. The review included an on-site tour of the Homeywell facility with a focus on the
highest probability source area (LACC, oil chip yards, engine test cells, and return well..) An additional day
included consultation on review of the Honeywell Conceptual Site Model and a meeting with the technical
consultants for Honeywell. On November 6, 2000 the technical consultants presented their interpretation of the
geology and hydrology and the flow and transport model supporting Motorola's interpretatio of historical
plume development. Meetings with both parties have demonstrated that significant effort has been expended
on collection and interpretation of site-specific data, and progress is being made on development of a site
conceptual model.

The TSC is planning to participate in an on-site technical working group. The report titled "Review of
Potential Source Areas Investigation Work Plan Honeywell International, Inc. 34lh Street Facility" was provided

The RPM requested that the ESD-LV TSC provide assistance in reviewing the Quality Assurance manual
(QAM) and the Standard Operating Procedures (SOP's) of a laboratory (i.e., Columbia analytical Services) that
will be analyzing samples from this site.

The U.S. Navy is planning to perform a Time-Critical Removal Action as part of the Installation Restoration
Program (IR) at the Naval Air Station North Island in Coronado, California. Under the IR Program the Navy is
investigating and cleaning up sites contaminated as a result of past waste operations and disposal practices. The
IR Program site involved is Site 5, the Golf Course Garbage Disposal Area, Unit 2. Site 5 was operated as a
landfill from the mid-1940s until 1965. After closing in 1965, the site was operated until 1983 as a transfer
station where solid waste was stored and prepared for off-site disposal. Between 1983 and 1984, the site was
converted to a golf course and is still in use today. Site 5, Unit 2 is an area south of the putting greens where
volatile organic compounds (VOCs) and petroleum hydrocarbons have impacted soil and groundwater.

The TSC completed an on-site audit of the laboratory and provided the Region with the report titled "Columbia

The Region X RPM has requested that the TSC evaluate statistical tests and approaches that have been used to
characterize UXO.

The Naval Air Station (NASON) Adak, Alaska covers approximately 64,00 acres in Alaska on Adak Island.
Near the western end of the Aleutian Islands. Adak Island became a military base in 1942, and in 1950, the
Navy took control of all defense facilities on the island. The island is characterized by high winds and frequent
storms. The southern half of the island is a Federal designated wilderness area, and the entire island is part of
the Alaska Maritime National Wildlife Refuge.

The primary focus of this evaluation will be to conduct an assessment of the UXO calculator that is used to
characterize sites contaminated with UXO. There are questions pertaining to the proper use and application of
the mathematical and statistical approaches that have been incorporated in this program.

Under the Base Realignment and Closure Act (BRAC) the Navy is required to identify and remediate all
hazardous materials including UXO. The identification and removal of hazardous materials must be completed
prior to the transfer of these properties to the private sector. In 1966, the Navy completed an initial assessment
study that identified 32 areas that potentially received hazardous substances, including chlorinated solvents,
batteries, and transformer oils containing PCBs, over a 40 year period. These areas include spill sites, and pits
for waste oil and fire-fighting training.

After reviewing site data the TSC performed a number of statistical tests and assessments. These tests and their
results plus a summary of a homogenity and an outlier test will be presented in a final report. The report was
prepared titled "Summary of Recent Results on Site Stats Evaluation Performed After the August 9-10 2000

The Region X RPM has requested the ESD-LV TSC to provide assistance in the identification of innovative
approaches for conducting vadose zone characterization, emerging fracture filling or compensation grouting
technologies, and manipulating the geochemical environment to precipitate toxic metals. The Bunker Hill
Mining District is located within the Coeur d'Alene River Basin in the eastern portion of the panhandle of
northern Idaho. Historic ore mining, milling, and smelting practices have resulted in widespread mining-related
contamination of the basin. In 1992, a ROD was signed for the non-populated areas of the Bunker Hill
Superfund Site (BHSS), and implementation began in 1995. In 1998, EPA initiated an RI/FS of mining-related
contamination in the Coeur d'Alene River Basin.

The TSC participated in a on-site visit. The purposes of the visit were to: 1) meet with Idaho State DEQ and
Silver Valley Trustees regarding provision of technical assistance for the Success Mine pilot in which the TSC
would develop a protocol for predicting the adsorptive capacity of materials useful in the passive treatment of
Acid Mine Drainage (AMD); and (2) meet with EPA officials regarding request for technical assistance in

The Project Officer requested that the ESD-LV TSC requested that the ESD-LV TSC provide assistance in
reviewing the proposed approach that is being suggested to "Krig" soil lead concentrations.

Exide operates a secondary lead smelter and batter manufacturing/distribution facility in Berks County,
Pennsylvania. Since 1991, several studies have been performed on soil, sediment and groundwater in areas
adjacent to and in the vicinity of the facility to investigate the occurrence of lead, arsenic, selenium and
cadmium that may be attributable to past facility operations. The Study Area covers approximately a one-
square mile area centered around the facility. The Study Area includes portions of Laureldale Borough and
Muhlenburg Township. Berks County, Pennsylvania, and is situated less that one mile north of the City of
Reading. The investigations conducted to date in the Study Area include the following:

• Soil sampling performed during 1992 (now referred to as Phase I investigation);
• Soil sampling performed between completion of Phase I investigation and July 2, 1993,
designated as the Phase II investigation;
• Soil, sediment and groundwater sampling performed under the Phase III investigation in 1994:
and
• The Phase IV soil and sediment sampling (1996).

The Region VII Toxicologist requested that the ESD-LV provide assistance in investigating the exposure
of children living in methamphetamine clandestine homes being used to manufacture methamphetamine.

The Anti-Abuse Act of 1988 established a Joint Federal Task Force on illegal drug laboratories. The Task
Force consisted of representatives of the U. S. DEA and the USEPA and representatives of the USCG.
Congress directed the Task Force to formulate a program for cleaning up and disposing of hazardous
wastes produced by clandestine drug laboratories.

The TSC met with the Toxicologist and discussed a number of exposure model(s) and data requirements
necessary for running the model(s). The TSC will participate in model assessment(s) and conducting
Monte Carlo data simulations.

The RPM requested that the ESD-LV TSC provide asistance in reviewing a hydrogeolocical program.
Note: this is not a Superfund related project. As such, the Region has provided the resources.

Region IV is involved with a major facility that injects municipal effluent into the subsurface in Florida via
a Class 1 underground injection well. At the time the well was permitted it was believed that the injection

57
-------
zone by the state, a highly permeable cavernous zone, would contain all the waste even though no
traditional confining zones (i.e., dense, thick shales) exist between the injection zone and the lowest
underground sources of drinking water (USDW.) The regulations for Class 1 injections wills prohibit fluid
movement out of the injection zone. Unfortunately, some of the monitoring wells located between the
injection zone and the lowest USDW have shown contamination related to the injectate including coliform
and nitrate. Because of the geology of the site it is difficult to complete monitoring wells that do not leak.
After a couple of years of negotiations. An Administrative Order on Consent (AOC) was negotiated to
design a study to resolve whether fluids from this facility have moved through formations away from the
injection zone and toward the USDW. The AOC required that the facility design a study involving ground
water tracers to assess this issue.
Specifically, the TSC will address the following: 1) assist in the evaluation and selection of the tracer(s) to
be used, 2) to determine if there might be some better way to address this issue, and 3) to assist in the
evaluation of the actual tracer study when it is conducted.

A preliminary screen of the available documents has been completed and data gaps identified. In response
to the identification of data gaps, additional documentation was received from the RPM in August. The
review is expected to be completed in October. The report titled "Evaluation of Confining Layer Integrity
Beneath the South District Wastewater Treatment Plant, Miami-Dade Water and Sewer Department, Dade
County, Florida (Draft)" dated 12/13/99. Following Regional review, the TSC will finalize this report.

On December 20, 2000, INEEL received the Miami-Dade Injection Well report from the Region with a
request to provide review comments. In general, the purpose of the review was to determine whether the
existing data sets, pertaining to geologic, hydrogeologic, and geochemical data, were sufficient to attribute
the observed contamination above the zone of injection to either (1) movement only through inadequately
sealed sells of (2) widespread movement through the confining layer. Specifically, the TSC was requested
by Region IV to review the data sets provided to evaluate the following issues.

1. Whether the existing data are sufficient to either prove or disprove the presence of a confining
layer above the zone of injection and, if it is present, whether it is capable of preventing
movement of injected fluids from the zone of injection into the overlying monitoring zones.

2. Whether the data sets support the Miami-Dade Water and Sewer Department's contention that all
of the observed contamination of the monitoring zone could have resulted from vertical flow
through unsealed bore holes

3. If the data are not sufficient to evaluate points 1 and 2, identify the additional data that should be
collected to provide definitive answers.

A TSC project team is evaluating the information provided by EPA, Region IV relative to those three
issues. A report presenting the findings of the evaluation entitled "Evaluation of Confining Layer Integrity
Beneath the South District Wastewater Treatment Plant, Miami-Dade Water and Sewer Department, Dade
County, Florida" was sent out for Peer Review. Following the evaluation of additional data and reviewing
Peer Review comments the TSC prepared and distributed the final report (see title above.)

The RPM requested that the ESD, TSC provide assistance in reviewing the sampling/analysis (S&A) plans
for characterizing site contaminants. The Riverpoint West area is located south of the Des Moines district.
Riverpoint West is bordered by SW 9* Street to the east, railroad tracks and Market Street to the north, and
the Racoon River to the west and south. Transient populations very frequently inhabit the undeveloped
and wooded places of the subject site. This population very often creates shelters and dump sites which
include non-hazardous and hazardous materials. Dump sites have been observed to contain motor oil
containers, liquid propane canisters, and cans of solvents containing aromatic hydrocarbons. The dump
site(s) also contain textiles, cardboard, bottles, cans, and plastic film.

The TSC reviewed available documents and provided the following reports "Field Analytical
Methodologies that Can Be Used at Riverpoint West-Des Moines Brownfields Superfund Site",
"Riverpoint Site Characterization Techniques" and "Technical Input for Phase II Monitoring at the
Riverpoint Brownfields Site." Additional support is anticipated.
