The Regional Remedial Project Manager (RPM) requested that the Environmental Sciences Division-Las Vegas
(ESD) Technology Support Center (TSC) provide assistance in evaluating a proposed protocol for soil sample
collection and analyses.
The Massachusetts Military Reservation (MMR) is a 22,000 acre facility located on Cape Cod, Massachusetts.
The MMR has been used since the 1950's for the training of military personnel. Currently, the MMR includes
Camp Edwards, where the Massachusetts Army National Guard and other National Guard units conduct annual
and weekend training. About 14,000 acres of Camp Edwards contains the Training Range, where small-arms
and large-arms firing ranges are located and maneuvers take place, and the Impact Area, where artillery and
mortar fire lands. This area (soils and groundwater) is contaminated with explosive type contaminants.
The TSC reviewed the provided sampling/monitoring/analytical suggested approaches. Appropriate comments
and suggestions were provided to the Region. The TSC participated in a meeting with the PRP's, RPM and
Regional staff. The TSC reviewed and provided comments pertaining to the proposed background sampling

The Savage Well site covers about 30 acres west of the center of Milford, NH and consists of a municipal well
and 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 from 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. Investigatons 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 volatile organic compounds (VOCs), including trichloroethylene (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.
The RPM has requested assistance in identifying innovative technologies to better assess the mass and location
of contaminants (dual tracer techniques) and then to participate in the removal ("chemically enhanced
remediation at neutral buoyancy") of DNAPL's at this site. TSC associated scientists prepared a project outline
and cost estimate titled "Surfactant-Enhances Aquifer Remediation of PCE at Neutral Buoyancy, O. K. Tool
Site, Milford, New Hampshire." Additional review of site documents and coordination of contaminant
characterization approaches with Regional personnel were completed. A pilot project for Surfactant Enhanced
Aquifer for Remediation was started and the field work is anticipated to begin in April.

The Remedial Project Manager (RPM) requested that the Environmental Sciences Division-Las Vegas (BSD)
Technology Support Center (TSC) provide assistance in reviewing statistical approaches that are being utilized
by the PRP to assess Ciba-Geigy data for site characterization and remedial purposes.
This 1,400-acre site includes 320 acres of developed area and the remaining wooded area. The manufacturing
facility which has operated since 1952 is composed of numerous buildings, an industrial waste water treatment
plant, and a lined reservoir for emergency storage of treated and untreated waste water. Chemicals have been
disposed of on-site in a number of locations, including a 5.2-acre drum disposal area, a 3.9 acre lime sludge
disposal area used for disposal of inorganic wastes, a 12-acre filter cake disposal area which received sludge
from the waste water treatment, 8.5 acres of backfilled lagoons, and a calcium sulphate disposal area. In 1978,
the drum and lime sludge disposal areas were closed, as was the filter cake disposal area. Currently,
contaminants are present in leaking drums, waste sludge, soil, and groundwater, Groundwater contamination is
migrating from these inactive disposal sites toward the river. The primary contaminants of concern addressed in
-------
this operable unit affecting the groundwater are VOCs including benzene, PCE, TCE, and toluene; and metals
including arsenic and chromium. A review of the geostatistical approach that will be implemented at the site
was completed. The TSC also attended a meeting with the Region and PRP's.
The TSC is currently waiting for the Region to provide the site data.

The RPM requested that the ESD-LV TSC provide assistance in analyzing groundwater samples for perchlorate^
The 1 '/i-acre Goose Farms site located near New Egypt, New Jersey was used as a hazardous waste disposal
area from the mid-1940s to the mid-1970s by a manufacturer of polysulfide rubber and solid rocket fuel
propellant. The majority of wastes were dumped into a pit dug through fine sand. Waste chemicals from
laboratories, drums, and bulk liquids were dumped into the pit. In 1978, the New Jersey Department of
Environmental Protection (NJDEP) found that a contaminant plume that originated in the waste pit area had
migrated north toward a nearby stream. Soil was also found to contain volatile organic compounds (VOCs).
This site is within 2 miles of 3 other NPL sites. Samples were collected and sent to the TSC for analysis. The
TSC analyzed the samples and submitted the report titled "Perchlorate Analysis for Goose Farms" to the Region.
The TSC participated in a number of discussions with the Region pertaining to the analytical results.

The Reich Farm site is an open, relatively flat, sandy area covering approximately 3 acres in Dover Township.
The site is surrounded by commercial facilities and wooded areas. During a 5 month period in 1971, 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 the land that they had rented out. These drums bore labels indicating that they
belonged to the Union Carbide Corporation. Trenches where wastes were believed to have been dumped were
also found. From 1972 to 1974 drums, trench waste, and contaminated soils were removed from the site by
Union Carbide. In addition, contaminated private wells were closed and a zoning ordinance was passed
preventing further groundwater use in the area.
The TSC was requested to help identify organic compounds found in groundwater samples. These compounds
are believed to have migrated from the Reich Farm site. Samples were sent to BSD and analyzed by BSD
research chemists. The identity of the compound(s) were determined. A report titled "Technical Report: Reich
Farm Superfund Site Identification of Styrene-Acrylonitrile Adducts Found in Groundwater" was provided to
the Region. A report by three ESD-LV scientists titled "Mass Peak Profiling from Selected-Ion-Recording Data
and a Profile Generation Model: Powerful New Tools for Identifying Environmental Contaminants" was written
and submitted for publication. Additional spectra was received for an analytical evaluation. A question
regarding the process involved in the identification of the styrene-acrylonitrile trimmers was answered. A
second unknown compound found in site extracts was identified by mass spectral interpretation and a review of
analytical method procedures. Also, data were received for additional unknown contaminants found in
groundwater near the site. These data were reviewed, mass spectra were interpreted, and the patent literature
was search. Interpretations leading to structural identity and the preparation of a report titled "Reich Farm
Superfund Site Further Study of Contaminants Found in Ground Water" was provided to the Region.

The Regional RPM requested that the ESD-LV TSC provide assistance in evaluating the use of a passive
method (the Gore Sorber) for sampling organic contaminants in monitoring wells.
The Aberdeen Proving Ground (APG) occupies 79,000 acres of land and water near the head of the Chesapeake
Bay. The APG consists of two areas that are listed separately on the NPL; the Edgewood area is 13,000 acres
and includes Gunpowder Neck, Pooles Island, Carroll Island and Grace's Quarters. The Edgewood area was
used for the development and testing of chemical agent munitions. From 1917 to the present, the Edgewood
area conducted chemical research programs, manufactured chemical agents, and tested, stored, and disposed of
toxic materials. The Edgewood area has large areas of land and water and numerous buildings, which are
contaminated or suspected of being contaminated. Virtually every land portion of the area is reportedly
-------
contaminated or potentially contaminated. Substances disposed of in the area include significant quantities of
napalm, white phosphorous and chemical agents.
The TSC reviewed site information and data. A TSC report that provides suggestions and recommendations as
to the use of the Gore Sorber to characterize site groundwater contamination was provided to the Region. The
information provided to the Region was titled "Evaluation of Passive Water Sampling Demonstration at the
Aberdeen Proving Ground". The TSC reviewed additional information and data and provided comments and
recommendations to the Region.

The RPM requested that the ESD-LV TSC provide assistance in assessing statistical approaches that were l
utilized by the PRP's to identify background soil concentrations.
Allegany Ballistics Laboratory (ABL) is located in Mineral County, West Virginia. ABL occupies 1,628 acres
and is situated on the flood plain of the North Branch of the Potomac River, along the West Virginia-Maryland
state border. Surrounding land use is primarily agricultural with some forestry. The facility has been in
operation since 1942, primarily for the research, development, and testing of solid propellants and motors for
rockets, ammunition, and armaments for the Navy. Operations at ABL have generated a variety of explosive
and solid wastes that were disposed of in on-site disposal areas. From 1970 to 1981, some of the waste was
stored in a drum storage area. Waste disposal and handling practices at the facility have resulted in several
source areas of concern.
The TSC reviewed the site data and the PRP's statistical approaches. A letter report with comments and
recommendations was provided to the RPM. The TSC received site data and completed some statistical
calculations for the Region. A report titled "Upper Confidence Limits for Arsenic, Cyanide, Mercury, and Lead
Computed from Allegany Ballistics Laboratory (ABL) Superfund Site Data" was provided to the Region.

The Buckingham County Landfill encompasses approximately 8 acres, including a 1-acre hazardous waste site
and a 7-acre solid waste landfill. The site is situated on 175 acres of wooded land. Love's Container Service
operated an unlicensed landfill from 1962 until February 1972. In November 1972, the Virginia State Board of
Health (VSBH) issued a permit to the facility to dispose of municipal waste. In 1977, the solid waste landfill
operation was closed and covered to the satisfaction of VSBH; however, the facility received interim Status as a
hazardous waste disposal facility. Subsequently, the facility accepted approximately 1,250 drums of used
organic solvents and flammable liquids and solids. These wastes were poured into a clay-lined evaporation
trench. After the liquids were poured into the trench, the empty barrels were buried in a separate trench. The
solid residue remaining after the liquids had evaporated was then dug out and emptied into hazardous waste
trenches.
A Record of Decision (ROD) was signed for this site in September 1994 which called for construction of a
RCRA cap over the hazardous waste portion of the site and long-term groundwater monitoring. At the time,
EPA favored excavation and offsite treatment of the waste but overwhelming public opinion swayed the final
remedy selection. The ROD has a contingency built in that requires excavation if there is an MCL exceedance
at a point of compliance well.
The responsible party's contractor (Parsons Engineering-Science) completed an extensive groundwater
investigation in June of 1997. The purpose of this investigation was to determine the most optimal locations and
depths for the compliance wells. The ROD indicates that: if there is an MCL exceedance at a compliance well, v
the well where the exceedance occurred must be resampled to confirm the level of contamination in that well is
in fact above the MCL. Parsons has provided information to outline their proposed procedure to confirm such
an exceedance. The focus of the TSC review will be: (1) To determine if the proposed statistical analysis
complies with the listed EPA guidances; (2) To determine if the proposed approach will confirm the
exceedance; and (3) to provide EPA Region III with recommendations regarding approval/disapproval of the
suggested approach.
The TSC is currently reviewing the provided information.

The Remedial Project Manager (RPM) requested that the Environmental Sciences Division-Las Vegas (ESD)
Technology Support Center (TSC) provide assistance in reviewing a proposed pilot testing of a density driven
convection technology. The RPM is particularly interested in the proposed fluorometric analysis, well
construction, piezometer spacing and the proposed length of the test period.
The location for the pilot study is located in the southern portion of DGSC in an area that originates just east of
the location of an above-ground fuel oil storage tank and extends approximately 1,000 feet to the east of the
tank. This site comprises an area used for fire training exercises where obsolete and unserviceable waste
chemicals were burned from the mid-1960s until the late 1970s. Three separate unlined pits were probably used
for fire training purposes. Flammable liquid chemicals and petroleum products were dumped into the pits,
ignited and then extinguished during the training exercises. Petroleum oils, lubricating oils, solvents, pesticides,
and herbicides may have been burned at the site.
The TSC reviewed the work task proposal and provided the RPM a report that contained suggestions and
recommendations for improving this effort. Additional support is anticipated.

The Remedial Project Manager (RPM) requested that the Environmental Sciences Division-Las Vegas (ESD)
Technology Support Center (TSC) provide assistance in evaluating the statistical procedures that were used in
evaluating groundwater data relative to the stated clean-up goals.
The 178-acre Old City of York site landfill was owned and operated by the City of York from 1961 to 1975.
Industrial wastes were reportedly disposed of on the site. In 1981, EPA and State investigation found that the
landfill was contaminating groundwater in the area with volatile organic compounds (VOCs). They also
discovered that contaminated liquids were leaching from the site into the nearby Codorus Creek, which is used
for fishing and other recreational activities. Local wells were contaminated, and the State advised affected
residents to find other sources of drinking water or to treat well water before consuming it. The surrounding
area is rural and residential.
The TSC was provided with the following data/information:
-Three Month Pump & Treat Performance Evaluation Report dated January 1997.
-Six Month Pump & Treat Performance Evaluation Report dated May 1997.
-Waste Management Inc.'s response, dated 11/7/97, to EPA's comments on the three and six month
performance evaluation report.
The Region was particularly interested in the following:
(1) An opinion regarding whether there is a sufficient data set to perform a statistical evaluation; and
-------
(2) An opinion on the appropriateness of the statistical technique utilized. If the technique utilized is not
appropriate, perform the statistical analyses with a detailed explanation of the statistical approach
used.
Following a review of the provided information, the TSC provided the Region with a report titled "Statistical
Evaluation of Groundwater Relative to Clean-up Goals". Discussions with the RPM pertaining to the provided
report were completed.

The 11 l-acre Revere Chemical Company facility, located near Nockamixon, PA, was an acid, metal, and plating
waste processing operation also suspected of accepting organic solvent waste. While the plant operated, waste?
containing chromic acid, copper sulfate, and other heavy metals, as will as sulfuric acid and ammonia were
stored on-site in unlined earthen lagoons. A U.S. District Court ordered the facility to close in 1969 for causing
contamination of a tributary of Rapp Creek. The company abandoned full and empty drums, waste-filled
lagoons, and piles of solid waste, In 1970, the Pennsylvania Dept. Of Health (DOH) treated and removed 3
million gallons of liquid wastes.
In order to identify where chromium represents a non-carcinogenic risk that exceeds a hazard index of 1.0, a
chromium speciation quantitative speciation sampling and data analysis program was developed for this site.
Data was obtained from 20 sampling locations, and the samples were analyzed for total and hexavalent
chromium. From the data, a statistical evaluation was performed to determine chromium speciation.
The TSC was requested to review and to provide comments on the statistical approach used to assess the
chromium speciation results, A report titled "Review of Chromium Speciation Program at Revere Chemical Site
Nockamixon Township, Eastern Pennsylvania" was provided to the Region. Additional data assessments were
completed as the PRP's have responded to the TSC's initial report. The TSC provided the RPM a report that
addressed the PRP's comments and concerns. The PRP's have again responded to TSC's recommendations.
The TSC is reviewing the PRP's response and provided the report titled "Review of the Procedure Proposed in

As part of a Remedial Investigation conducted at this Washington, D. C. Spring Valley Site, the ASIC collected
soil samples at background locations and at a number of points-of-interest (POI's) sites. The COE's sampling
effort was intended to determine whether, and to what extent, contamination had resulted from past Department
of Defense (DOD)-related activities. EPA Region III concurred with the conclusions presented in the final RI
report, which included COE's sampling analytical results for all POIs and a corresponding human health risk
assessment.
In 1996, a resident in the community hired a contractor to perform landscaping activities on his property. The
contractors were overcome by noxious fumes and rushed to a nearby hospital. This incident prompted further
investigation in which arsenic was found at 1200ppm near the property. As a result of this incident, the D.C.
government is questioning the selection of contaminants of concern (COCs) used on background statistical
analysis and the subsequent risk assessment performed by Parsons Engineering Science, Inc.
To determine if the appropriate statistical analysis and conclusions were made regarding the background
analysis, the Region requested that the statistical analysis, performed by Parsons, be assessed to determine if the
appropriate analysis was performed. The Region also requested assistance in determining if the appropriate
COC's were selected or eliminated based on the background statistical analysis. In addition, EPA split samples
were taken during this investigation. The Region requested that appropriate statistical analysis to be performed
by the TSC on the EPA data, as well as determine the COC's based on EPA split data samples.
The TSC received available data and is currently evaluating the statistical tests that were previously completed.

The Regional RPM requested that the ESD-LV TSC provide assistance in reviewing a work plan that was
implemented by the PRP's to determine sources of sub-surface(s) combustible gases.
-------
Tybouts Comer Landfill was constructed in a sand and gravel pit located in northern Delaware, 10 miles west of
the Delaware River. The main landfill area is about 47 acres and is located near the confluence of Pigeon Run
Creek and Red Lion Creek. The fill ranges from 5 to 40 feet thick. Between 1968 and 1971, this privately
owned landfill accepted both municipal and industrial wastes, including volatile organic compounds (VOCs) and
various other organic and inorganic chemicals. Tybout's Corner was built without a clay liner or other
impervious material below the fill, and no clay cap was placed on top of the fill after it was abandoned.
Previous EPA studies have revealed that two shallow aquifers beneath the site are contaminated with the above-
mentioned chemicals. About 42 homes and facilities surround the entire landfill property and most of these have
wells that draw from the aquifers contaminated by the site.
After gases were detected outside the landfill, the PRP's did a limited field survey, to identify the extent of the
combustible gas migration and confirmed that the gases were located along nearby homes. Immediately, 38
vents connected to three blowers were installed adjacent to the landfill. The vents/blowers were successful in
pulling back the gas plume with the exception of one area. The TSC reviewed the PRP's work plan and
provided the RPM with suggestions and recommendations as to additional monitoring requirements. Additional
review comments were provided to the Region pertaining to the "Tybouts Comer Landfill Gas Migration
Report".

The RPM requested that the ESD-LV TSC provide assistance in reviewing on and off-site data to determine
background concentrations of arsenic and manganese in groundwater.
The Woodlawn County Landfill site covers approximately 37 acres in Cecil County, Maryland. The property
was a privately owned sand and gravel quarry before it was purchased by the County in 1960. The County
owned and operated the site as a municipal landfill from 1960 until 1978 when the State issued an order that
prohibited the County from placing additional municipal wastes into the landfill. During operation of the
landfill, two large quarrying pits were filled with agricultural, municipal and industrial wastes. State records
document the disposal of polyvinyl chloride (PVC) sludge at the site by the Firestone Tire & Rubber Company
(Firestone). The PVC sludge, which contained residual vinyl chloride, was initially disposed of into three
segregated disposal cells. In 1978, the county began operating a municipal waste transfer station at the site.
The TSC participated in a conference call with the RPM and Geraghty and Miller staff pertaining to statistical
approaches that could be utilized to characterize site data. TSC personnel provided statistical assistance in
determining background levels of inorganic contaminants. The PRP's have responded to initial TSC
recommendations. The TSC reviewed the PRP's comments and provided the Region with background and on-
site data tables. The Region had a number of questions pertaining to the data tables and a possible spatial
display of the data. The TSC is currently addressing these questions.

Koppers Co. Inc., operated milling, wood-preserving, and pole storage facility in the Charleston Heights District
of Charleston, Charleston County. South Carolina, during 1925-78. The 127-acre site is in a mixed
industrial/residential area. It is bordered on the west by Ashley River, and on the north and south by industrial
facilities. Approximately 94,00 people live within 4 miles of the site.
Sources of hazardous substances on the site include a pit where timbers were soaked in creosote wood
preservative, the "drip pad area" where the timbers were stored, and a bermed area that received contaminated
sediment from canal dredging on the site. Southern Dredging Co. Leased part of the site in 1978 after wood-
preserving operations had stopped. In 1984, the company dredged a canal from the Ashley River, intersecting a
waste disposal area. Dredged materials were placed in the bermed area.

Stauffer Chemical Company is located in an industrial area between Anclote Boulevard and the Anclote River
in Tarpon Springs, Pinellas County, Florida, about 1.6 miles east of the Gulf of Mexico. Stauffer purchased the
160-acre facility from Victor Chemical Works in 1960. The facility's ownership has changed several times; it is
currently owned by Stauffer Management Company.
From 1950 to 1981, the facility manufactured elemental phosphorous ore. The processed ore was shipped off-
site to be used primarily for production of agriculture pesticides, food-grade phosphates, and flame retardants.
The Region requested information and/or approaches that could be implemented which would identify an
association between offsite radioactive slag materials developed as a by-product of elemental phosphorous at the
Stauffer Chemical site. It appears to be "common knowledge" within the community that the slag materials at
the site were given to local contractors and homeowners, but the Region has not been able to obtain
specific/legally defensible records or manifests to document these activities. Further, no one has come forward
to attest to transporting the slag from the site to any given location.

The Taylor Road Landfill site consists of 40 acres. It is next to two other municipal landfills. The Department
of Transportation (DOT) Borrow Pit landfill and the Hillsborough Heights Landfill. These three landfills
occupy a total of 200 acres. The Taylor Road Landfill operated from 1975 to 1980, and the DOT Borrow Pit
Landfill and Hillsborough Heights Landfill both operated from 1980 to 1984. The three landfills were used for
the disposal of municipal refuse, but unknown quantities of industrial wastes may have been dumped at the site
as will. Private wills in the area are contaminated with volatile organic compounds (VOCs) including benzene
and vinyl chloride and heavy metals including lead from the former waste disposal activities at the site.
Consuming contaminated groundwater and dairy products poses a health hazard.
The Region has selected natural attenuation with contingent corrective actions if necessary, as the remedial
remedy. The Region is concerned about assessing site data in determining if the natural attenuation remedy is
working. The TSC was requested to assess and review the proposed trend analysis that is being prepared by the

The Tennessee Products (TP) Site, located in south Chattanooga, TN consists of a former coke production
facility, its associated uncontrolled coal tar disposal areas, and approximately 2.5 miles of sediments in
Chattanooga Creek that are all contaminated primarily with polycyclic aromatic hydrocarbons (PAHs). The site
was placed on the National Priorities List (NPL) in January of 1994 based on an EPA multi-media study of
Chattanooga Creek and on a Health Advisory issued by the Agency for Toxic Substances and Disease Registry
(ATSDR) in 1993 concerning contact with the coal tar deposits.
The ESD TSC participated in a contaminant migration study being performed by the Velsicol Chemical
Corporation under a RCRA order for their facility which is located adjacent to the TP Site. There are three
springs on the TP Site which will be monitored as part of a dye trace study. The dyes will be used to document
the movement (flow) of groundwater. The TSC analyzed water and dye receptors collected from TP site
locations. The results from the initial analysis of samples were provided to the Region in a report titled "Dye

The Region VI Remedial Project Manager (RPM) requested that the TSC provide assistance in statistical and
sampling issues related to characterizing site contaminants.
The 25-acre Texarkana Wood Preserving Company site, located in Bowie County, Texas, is an abandoned
wood-treating facility that operated under various owners from 1909 to 1984. When the site was placed on the
NPL in 1985, approximately 793,000 gallons of hazardous waste were stored in pressure vessels, steel tanks,
retention ponds, surge tanks, and three evaporation ponds. All units were heavily contaminated with creosote
and pentachlorophenol (PCP) used in the treatment process, as well as several by-products. The TSC evaluated
previously collected data. The TSC utilized geostatistics for assisting the Region in identifying the geographical
distribution of site contaminants. The TSC evaluated monitoring data and attended a meeting in Texarkana.
The TSC participated in numerous conference calls with the RPM and has provided soil contamination maps of
site contaminants. The TSC was also involved with modeling the groundwater plume. A meeting with the
RPM, State of Texas personnel and TSC staff at ESD-LV to discuss monitoring design approaches was
completed.
The focus of this project has been the specific data needs for upcoming groundwater and soil sampling and
identification of alternative conceptual models and modeling approaches. A meeting was held in Houston,
Texas with the Texas Natural Resource Conservation Commission (TNRCC), EPA Region 6, Roy F. Weston,
Inc., and the TSC. The sampling and data gathering recommendations presented in the INEEL Groundwater
Modeling Approach and Data Requirements memorandum of August 20, 1997 were accepted and specific
sampling locations identified. A set of alternative conceptual models and analysis scenarios proposed by the
TNRCC were considered at the meeting. Those that included pump and treat were removed from consideration
at the suggestion of EPA Region 6. All other conceptual models are amenable to analysis by the INEEL
GWSCREEN code, but some of the scenarios include diversion of flow and a more realistic flow model (such as
the USGS MODFLOW model) will be applied. The TSC reviewed a number of revisions of the draft and final
sampling plans. The TSC is participating in the assessment of sampling/monitoring data.

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.
15
-------
St. Joe Minerals Corporation operated the site, disposed lead,cadmium, and zinc- inch mine tailings over
approximately 600 acres in a 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 die site in 1977, when an estimated 50,000 cubic yards of tailings slumped into the Big River
during a heavy rain. 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 is currently being reviewed by the Region and the Agency for Toxic

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 ESD TSC's X-Ray Fluorescence
technology and equipment to measure site contaminants. The ESD TSC is continuing to support this effort. The

Frontier Fertilizer is a 13-acre site located near the eastern boundary of the City of Davis in Yolo County,
California. The Barber and Rowland Co. operated a pesticide and fertilizer distribution facility on the site from
1972 to 1982. Operations consisted of delivering pesticides, herbicides, and non-bulk chemicals in cans,
drums, and other containers. Currently, the site is used as a maintenance yard for agricultural equipment. Both
the Barber and Rowland and Frontier Fertilizer companies used a former disposal basin, approximately 4,000
cubic feet in volume to dispose of unused pesticides and fertilizers.
Surface and subsurface soils in the area of the former disposal basin are contaminated with 1,2-dibromoethane
(EDB), 1,2-dichloropropane (1,2-DCP), 1,2-dibromo-3-chloropropane (DBCP), disulforon, ethyl parathion,
Treflan, and Eptam. EDB, 1,2-DCP, and DBCP were also found in groundwater samples collected from on-site

McFarland is a small, mostly latino, agricultural town about 25 miles north of Bakersfield, California. The town
is surrounded by fields of crops such as cotton, kiwi, grapes and almonds. In 1984, local and state agencies
identified and confirmed a childhood cancer cluster in McFarland. Between 1975-1989 14 children under the
age of eighteen were diagnosed with 11 different types of cancer including leukemia, brain, liver and bone
cancer. Since the last investigation, CA DHS has confirmed 7 additional childhood cancer cases, which makes
the cancer rate twice the normal rate over the past 21 years in McFarland. California DHS led an investigation
of the cancer cluster which included an epidemiological study, soil sampling and drinking water well sampling,
review of air data from a UC Davis Research Project, health exams for 1700 children and a four county study on
childhood cancer to determine if cancer rates in agricultural communities were higher than in urban areas.
The TSC received the data for auditing from the TPO. The TSC completed the audit and provided the Region
with a report titled "Review of Electronic and Hardcopy Data for McFarland Superfund Site Samples". The
Regional Project Officer requested that the TSC provide information pertaining to the analysis of
ethylenebisdithiocarbamate analytical methods. Information about the analysis of these contaminants were
provided to the Region.

The RPM requested that the ESD-LV TSC provide assistance in developing a sampling/monitoring design to
characterize DDT contamination in local residential areas.
The 13-acre Montrose Chemical Corp. Site was the location of a plant that manufactured the pesticide DDT
from 1947 until 1982. Operations included formulation, grinding, packaging, and distribution of the pesticide.
Various locations across the site were used for storage of either DDT or waste products. The area used as a
settling and recycling pond for process wastes was completely unlined until 1970, when it was lined with
concrete. In 1985, Montrose regraded and paved the site with asphalt to reduce the further migration, of
contaminants until final cleanup at the site. Approximately 3,000 people live or work within 1/4 mile of the
site. The two upper aquifers are contaminated, but neither is used as a source of drinking water. Storm water
flows from the site into the Normandie Avenue Ditch, to the Kenwood Drain, to Torrance Lateral, Dominquez '
Channel, Consolidated Slip, and finally into Los Angeles Harbor. Soils, surface water, and groundwater are
contaminated with DDT and volatile organic compounds (VOCs). t
The TSC evaluated available contaminant data and attended a planning meeting with California State, USCDC
Region and private citizens. The TSC has provided the Region with a suggested sampling/monitoring approach
that could be implemented to characterize soil DDT contamination. The sampling/momitoring approach was
reviewed by a number of involved parties. The TSC is currently responding to the reviewers comments.

-------
The Newmark Groundwater Contamination site covers a portion of the contaminated area of an essential
groundwater aquifer underlying the City of San Bernardino. Groundwater contamination from other sources in
the Bunker Hill Basin Aquifer, such as Norton Air Force Base to the south and Camp Ono/Muscoy to the
southwest, are not considered parts of this site. Although the disposal occurred in the late 1950's through the
mid-1960's, the problem was not discovered until a water supply monitoring program was instituted in 1980. A
plume of chlorinated solvents, tetrachloroethylene (PCE), and trichloroethylene (TCE) closed 13 water supply
wells with a 4-mile radius of the site.
The TSC evaluated GC/MS data produced by Intertek Testing Services Environmental Laboratories. Hard
copies of the data backed up by magnetic tape was provided to the TSC. However, these tapes were
inadequate. The TSC is waiting for the delivery of additional tapes.

Major Contaminants: Perchlorate Total 2nd. Qtr.Exp.$33,066 PC&B:$2,000
The Regional Project Manager requested that the ESD-LV TSC provide assistance in critically reviewing the
California DHS analytical protocol for detection of perchlorate to the 4 ppb detection limit. This Ion
Chromatographic method has been instrumental in discovering perchlorate in groundwater and surface water
supplies in California, Arizona and Nevada. It is important to establish the reliability of this method to detect
perchlorate in the 4 to 18 ppb provisional reference dose range. This evaluation will also consider the effects of
high dissolved solid concentrations typically present in both the groundwater and surface water of the arid
southwest.
This contaminant may pose a health risk as drinking water in the Las Vegas Valley contains perchlorate. The
levels are within the 18 parts per billion protective guideline accepted as safe by California health officials.
Perchlorate is found in such compounds as ammonium perchlorate, which has been manufactured at two
locations near Henderson, Nevada. Perchlorate is not regulated by the Federal Safe Drinking Water Act.
A report titled "Interim Technical Report Review of Methodology for the Analysis of Perchlorate in Water"
was provided to the Region. In addition, the report titled "Interim Technical Report Methods and Quality
Assurance for the Analysis of Perchlorate in Water" was completed. Due to the costs associated with this
effort the TSC is not going to conduct a multi-laboratory methods performance, sample holding time, and
preservation studies under this specific project.

This Phoenix, Arizona site is comprised of approximately 1000 homes which were impacted by smoke from a
1992 fire of the QPC facility, a circuit board manufacturer. This fire burned for approximately 8-12 hours with
the smoke plume blowing directly east and northeast of the facility. Subsequent to the fire, health effects
believed to be a direct result of this fire occurred. Based on these concerns, EPA will sample various homes in
the community. The issue is to establish an appropriate number of homes to be samples. The Region wanted
the TSC's assistance in determining how many homes should be sampled in the upcoming investigation.
Sampling for dioxin, metals, acid anions, semi-volatiles and particulates was conducted. In addition, soil,
indoor/outdoor air, air ducts (vents), evaporative cooler pads and house dust samples were collected.
Following an assessment of available data the TSC provided the Region with a statistically valid approach for
sampling the affected areas. Samples were collected and analyzed. The TSC provided assessment of the
sampling/monitoring data. The report titled "Statistical Analysis for Anions, Metals, PAH's and Dioxins Phase,!
Sampling, QPC Site, Phoenix, Arizona" was provided to the Region. Additional data assessments will be
completed by the TSC and the report "Statistical Analysis for Anions, Metals, and PAH's Phase II Sampling,

Four sites within the San Fernando Valley (SFV) are currently on the National Priority List (NPL): North
Hollywood, Crystal Springs, Pollock, and Verdugo. Currently EPA is managing the four areas as one large site
referred to as the SFV Superfund Site. This site includes the four NPL sites and adjacent areas where
groundwater contamination is known or presumed to have migrated. There are currently a total of 87 RI
monitoring wills located inland adjacent to the four NPL sites. Three of the shallow water table wells are
screened in bedrock and do not have pumps installed. Trichloroethylene (TCE) and tetrachloroethylene (PCE)
data were used to separate the 84 Rl wells into two categories: those recommended to be sampled quarterly, and
23
-------
those recommended to be sampled annually. All 84 of the RI wells were originally included in the annual
monitoring program. Of these 84 wells, 41 historically have concentrations of TCE and/or PCE in excess of
federal and state maximum contaminant levels (MCLs) were placed into the quarterly monitoring program.
The Region is concerned with both PCE and TCE as contaminants in the groundwater. It has been suggested
that kriging using plume maps might be a good way to access changes in contaminant concentrations over time.
In addition, the Region is interested in any other means of characterizing migration of the contaminant plumes
or changes in contaminant concentrations over time.
The ESD-LV TSC reviewed the provided data and identified a number of data assessment methods that could
be used to assess contaminant behavior over time. The TSC provided some additional recommendations to the
RPM. The TSC provided suggestions and comments pertaining to available data assessment techniques and
methods to the Region. Additional support is anticipated.

The Regional Hydrogeologist requested that the ESD TSC provide assistance in evaluating the soil gas sampling
effort that was conducted on a portion of this site.
The Fort Lewis site occupies approximately 650 acres of the Fort Lewis military reservation. The Logistics
Center is an industrial complex comprised of warehouses, motor pools, maintenance facilities, and an equipment
disposal yard It was built in the early 1940s, and is used for storing supplies and providing maintenance of
military equipment and vehicles. The primary contaminant, trichloroethylene(TCE) is a common industrial and
commercial solvent and degreaser and was used for maintenance activities until the mid 1970's. The waste TCE,
which was often combined with waste oil, was disposed of at several areas within the Center.
The DRMO Yard is used currently as a general-use temporary storage area. Stored materials include equipment
containing residual polychlorinated biphenyls (PCBs). In the past, unknown quantities of stored materials
included drums containing waste TCE and equipment containing PCBs.
A number of questions pertaining to soil gas date evaluation, sampling locations relative to the contaminant
groundwater plume location and specific sampling methods were of interest to the Region. The TSC evaluated
the provided data and furnished some suggestions and recommendations to the Region to enhance the soil gas
monitoring effort. Additional support is anticipated.

The OSC requested that the ESD TSC provide assistance in fingerprinting PAH's for determining creosote-
bases versus oil based contaminants.
The OESER site is an operating wood treatment facility located in Bellingham, Washington. The facility has
been in operation since 1940, and over the years has treated utility poles with creosote and pentachlorophenol.
PAH's have been detected in soils on and in the vicinity of the site. The levels of these contaminants may be
sufficiently high to require risk management action. At issue is whether the contaminants are creosote or diesel
fuel related. For example, oil contaminants have been reported in the vicinity; in addition, urban activity could
be responsible for the presence of the elevated levels of PAH's.
The TSC analyzed samples from the OESER site and provided an interim report to the OSC. Following some t
additional analysis and data assessment. The final report titled "OESER Superfund Site Differentiation of
Creosote and Oil Contamination in Soil and Groundwater Samples" was submitted to the Region. The RPM
requested assistance in reviewing past site characterization sampling and monitoring efforts. Following the
review the RPM requested the TSC to design an off-site effort that would adequately characterize soil dioxin
contamination. The sampling/monitoring design is in process.

The Regional RPM requested that the ESD-LV TSC provide assistance in characterizing volatile organic
contaminants on this site. The Oregon Fir Supply is located in Portland's Development Commissions former
Hoiman Redevelopment Area. The site is also located in the western portion of the wellhead protection area for
the City of Portland's backup water supply well field. Historically, the site has been occupied by a heavy
25
-------
construction company, a solvent drum recycler, a pharmaceutical testing laboratory, and more recently by airline
service companies. Both chlorinated solvents and petroleum hydrocarbons have been detected in soil and
groundwater across the site. The areas of contamination appear to be related to at least two descrete sources,
including an acid neutralization sump and a solvent drum storage area. There is about 10 feet of silty sandy soil
above the water table with varying concentrations of solvents and petroleum hydrocarbons.
Soil samples were collected and analyzed for soil VOC's. A preliminary report identifying the analytical results
was submitted to the RPM and to the Oregon Department of Environmental Quality. A report titled "The Effect

Contaminant concentration data from Superfund sites often appear to follow a skewed probability distribution. The
lognormal distribution is frequently used to model positively skewed contaminant concentration distributions. The H-statistic
based upper confidence limit (UCL) for the arithmetic mean of a lognormal population is recommended by the U.S. EPA
guidance documents, and is widely used to make remediation decisions at Superfund sites. Recent work in environmental
statistics literature, however, has cast some doubts about the performance of the H-statistic based formula and the UCL of the
arithmetic mean of a lognormal population. This issue paper is mainly concerned with the problem of computation of the
UCL when the contaminant concentration distribution appears to be highly skewed. The issue of using the coefficient of
variation (CV) in environmental data analysis is also addressed.
The TSC manager requested this issue paper as a result of past statistical technical support projects that have indicated
problems with some recommended statistical data assessment procedures and techniques. The statistical issues addressed are
directly related to ESD TSC projects in which Dr. A. K. Singh has been the technical lead . This issue paper will provide
guidance in assessing site data for characterizing and remediation contaminants. The Issue Paper was written and approved as
an ORD Project Report.

The Federal Facilities Forum requested the ESD to prepare an Issue Paper addressing the current "State of Technology" with
regards to "On-Site Analytical Methods" for identifying explosive contaminants in water. In addition, this issue paper will
discuss appropriate sampling/monitoring approaches that may be implemented to characterize these types of contaminants.
PURPOSE AND SCOPE
Evaluating sites potentially contaminated with explosives is necessary to carry out EPA. Department of Defense, and U. S.
Department of Energy policies on site characterization and remediation under the Superfund, Resource Conservation
Recovery Act, Installation Restoration, Base Closure, and formerly used defense site environmental programs. Facilities that
may be contaminated with explosives include active and former manufacturing plants, ordnance works, Army ammunition
plants, Naval ordnance plants, Army depots, Naval ammunition depots, Army and Navy Proving Grounds and burning
grounds.
This issue paper will provide guidance to Remedial Managers for the use of on-site methods to measure explosives.
The outline for this paper is as follows:
-Explosives Compounds of Interest, Frequency of Detection
-EPA Office of Drinking Water Health Advisory Levels
-Holding Time Study for Explosives in Groundwater and Surface Water
-Water Methods Available (colormetric, immunoassay, biosensors)
-Detection Limits
-Interference/Cross Reactivity with Secondary Target Analytes

Contaminant concentration data collected from different sampling locations of a Superfund site typically has a
skewed distribution, and is log-transformed before performing kriging for site characterization. The estimates obtained from
kriging are then back-transformed to get estimates of contaminant concentration at the site. The formula for this back-
transformation depends not only on the estimated concentration in the log-scale, but also its estimation error. As a result, the
back-transformed estimates, in some situations, turn out to be orders of magnitude higher than the max.mum observed

concentration at the site. A similar result is obtained in computing the H-statistic based upper confidence limit (UCL) of the
arithmetic mean of the contaminant concentration distribution, when the data distribution is modeled by the log-normal
probability function. The problems with using the H-statistic based formula for computing UCL were addressed in an earlier
issue paper. This issue paper will use unconditional simulation and conditional simulation with data from Superfund sites to
evaluate the method of lognormal kriging, and its performance will be compared to some robust kriging procedures. The
software packages SCOUT and GEO-EAS will be used in comparative kriging procedures.

One mission of the National Exposure Research Laboratories (NERL), ESD-LV TSC is to provide Superfund
Technical Support to Regional Offices and other EPA Technical Support Centers upon request through the TSC for
Monitoring and Site Characterization. Many of these requests deal with special data audits and data assessments.
This contributes to ESD-LV's contaminant measurement efforts from the standpoint of improving data quality,
sampling, analytical and quality assurance techniques that are used to produce data for contaminant characterization
and exposure assessment purposes. The Superfund Program's Emergency Response Team (ERT) is a TSC that
provides technical support for emergency response actions and for site characterization technologies and quality
assurance to On-Scene-Coordinators (OSCs) at numerous Superfund sites across the Regions.
The ERT TSC is participating with the ESD-LV TSC in a technical support effort to integrate and implement various
QA parameters in site characterization data collection and data assessment processes. This effort will be used to
support ERT and the ESD-LV TSC's projects at many sites such as Fort Ord, Hunters Point and the Marine Corps
Air Station Yuma. ESD-LV has in place an Infra-Agency Funding Agreement with the Technology Innovation
Office (TIO) of the Office of Solid Waste and Emergency Response (OSWER) to provide Superfund technical
support to OSWER and Regional Offices. The initial prototype of this data integration/assessment was developed
and demonstrated to the EPA Project Officers. Additional interim reports were prepared. The ERT Project Officer
(Bill Coakley) attended a number of progress briefings and demonstrations.
