    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

    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.

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

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

    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.

    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

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

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

    The Regional On-Scene Coordinator (OSC) requested that the ESD-LV TSC provide assistance in determining
    if previous sampling/monitoring efforts have  adequately characterized on-site and off-site contamination.

    The site is classified as an environmental justice site, with a large, middle-economic class, minority population.
    This property, as well as surrounding properties, which total approximately 120 acres, is located within
    Chicago's largest Brownfields redevelopment area.

    The Dutch Boy site consists of an approximately 5 acre empty lot located at 12000 to 12054 South Peoria Street
    and 901 and 935 West 120th Street in Chicago. The site is located in a primarily industrial area and includes
    concrete loading docks, concrete paved surfaces, and two railroad spurs which are located in areas with exposed
    soil and vegetation. The site is bounded by the Illinois Central Gulf Railroad tracks to the south, an empty lot
    (previously International Harvester/Navistar operations) to the west, 120th Street to the north, and South Peoria
    Street to the east.

    The TSC reviewed available site data and provided an initial report to the OSC titled "Preliminary Review of
    the Draft Extent of Contamination Survey Dutch Boy Site, Chicago, Illinois". A sampling/monitoring approach
    to adequately characterize off-site contamination was provided to the OSC in the First Qtr. of FY98.
    Discussions with the OSC pertaining to the sampling/monitoring approach were completed.

    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
    Substances and Disease Registry.

    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
    RPM requested special analytical support. The TSC continued to analyze a number of samples collected from
    this site to determine the amount of total and bioavailable lead for risk assessment purposes. A preliminary data
    report was provided to the RPM.  The TSC also reviewed the "In Vitro Analytical Method" and provided
    comments to the Region. The TSC is getting ready to participate in the "Vitro Bioaccessibility Method
    Validation Study." This study will be completed during the third quarter of FY98.

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
and off-site monitoring wells.

Samples from this site were apparently sent to a laboratory known as AnLab Analytical.  The EPA is          t
conducting an investigation of this laboratory for allegedly providing false statements and/or false data.  The
Regional TPO has requested the TSC to perform an audit of AnLab's generated data. The initial audit of 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

   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

   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.

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.

    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
    of the Sample Volume on the Precision and Bias of Soil VOC Measurements" was provided to the Region.
    Additional contaminant characterization reports are in process.

    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

           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.
