A geostatistical analysis of the distribution of soil contaminated with polychlorinated biphenyls (PCBs) was
conducted to develop the sampling plan for the F. O'Connor Superfund Site in Augusta, Maine. The analysis was
designed to support attainment of target cleanup goals as specified in the U.S. Environmental Protection Agency
(EPA) Record of Decision (ROD) for the Site. Over 450 soil samples were collected during Remedial
Investigation and pre-design phases of the study. Chemical analysis of these samples were performed for PCBs
using both laboratory and field screening methods. Samples were initially collected at grid locations, while
subsequent samples were collected to define areas of higher concentrations and to determine the clean boundaries
of the site.
Analysis of the comprehensive data set as well as data subsets indicated a log-normal distribution of the data. Data
subsets were developed based on knowledge of waste disposal and contaminant distributions. Variogram analysis
was conducted using indicator parameters corresponding to the ROD specified threshold limits of 1 and lOppm
PCBs.
The RPM has requested that the CRD-LV TSC evaluate the geostatistical model used by the PRP, the use of the
geometric mean to establish compliance with the cleanup criteria, and to comment on the use of composite
samples. CRD-LV personnel reviewed the provided data and submitted an initial response. Additional reviews of
the utilized statistical procedures are in process.
Following the review and acceptance of the Work Plan, providing on-site oversight and field audit for the
"Preliminary Soil/Sediment Screening/Sampling" of the Phase IARI activities conducted by the PRPs was
required. Field audit oversight included observing and documenting the field activities, and analyzing split
samples using fix-lab analysis. Reviews of site documents were completed. Split samples were collected and sent
-------
to CRD-LV for analysis. The analysis was completed during this quarter. In addition, a field on-site audit was
completed. The results of the audit with suggestions and recommendations were sent to the RPM. The initial draft
of the data validation report was provided to the RPM. Additional technical support is anticipated.

The Regions Remedial Project Manager (RPM) requested that the Characterization Research Division Las Vegas
(CRD-LV), Technology Support Center (TSC) provide assistance in field measurements and monitoring design.
The site is in design and of particular concern is the potential remediation of a wetland area contaminated with
PCBs and pesticides. The Eco risk has been completed in draft form. There is still some work to be done to
complete the Eco risk. The remaining work is dependent upon knowing, or being able to extrapolate from existing
data, the PCB concentrations in the area of the wetland that has not been characterized. It has been determined that
the extrapolation is not possible with remaining wetland has been decided upon. It has been decided to use field
analysis methods (Immunoassay) to determine the extent of contamination and to complete the Eco Risk.
The TSC provided an assessment of available data and suggested a possible design approach. The RPM decided to
utilize another approach for measuring PCBs. As such, the involvement of the TSC may be limited.

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 and the
Michaelsville area. The Edgewood area is 13,000 acres and includes Gunpowder Neck, Pooles Island, Carroll
Island, and Graces Quarters.
Preliminary on-site groundwater sampling has identified various metals, phosphorus, and volatile organic
compounds (VOCs) including chloroform and benzene. Preliminary on-site soil contamination sampling has
identified various VOCs, metals, and unexploded ordnance in surface and subsurface soil.
To address some risk assessment issues, the RPM requested that the CRD-LV TSC review the report, "Installation
Restoration Program Carroll Island/Graces Quarters, Aberdeen Proving Ground Risk Assessment Framework,
Draft, May 1995." Based upon the data in the report, the RPM requested that the CRD-LV TSC address the
following questions:
• Is it appropriate to use non-parametric methods to determine site-wide concentrations when contaminants were
detected in <50% of samples?
• If yes, how should non-detects be handled?
• Is it appropriate to use the UTL to define background concentrations in inorganics (for comparison to on-site
levels)?

and the Pennsylvania Department of Environmental Protection (PADEP) have been working to ensure that the
entire property is "clean" prior to its transfer to the City of Philadelphia. As part of the clean-up effort, it was
determined that a background study was necessary to characterize background or ambient soil constituent
concentrations in the area.
The TSC reveiwed and assessed the available data and provided a report to the RPM titled "Review Comments on

The Saegertown site covers about 100 acres that contain several industrial operations. In 1980, State analysts
discovered volatile organic compundds (VOCs) in the Saegertown Municipal Water Authority's Well #2. Several
potentialsources of VOCs and lead contamination have been identified on site. GATX cleaned and repaired
railroad tank care here from the mid-1950s to 1965 disposing of wash water, sludge, and tanker waste on site. EPA
tests in 1984 found VOCs and polycyclic aromatic hydrocarbons (PAHs) in on-site pond sediments and soil. On-
site monitoring wells also revealed contamination from lead and other heavy metals. Region III has completed the
RI/FS and ROD at the site and are proceeding with pre-design efforts to delineate the extent of the ground water
plume. The CRD-LV TSC was requested to statistically assess if the contaminant levels in groundwater were
increasing or decreasing. An assessment of the site data was completed. A report titled "Trend Analysis for Total
VOCs: Saegertown Site" was provided to the Region.

The Marzone, Inc. Pesticide plant was established in 1950 on a 1 Vi acre site in Tifton, Georgia. The facility
operated until 1982, when a new owner began using its warehouse as a distribution center. Chevron Chemical Co.
Started blending dry powders at the site in the 1950s and constructed a building for formulating liquids some time
during 1963 through 1964. The owners added a drum storage facility, three 10,000-gallon solvent tanks, one
12,000-gallon toxaphene (insecticide) tank, and a wastewater pond. The site has changed ownership five times
since 1970; four of these owners were agricultural chemical companies.

The Allied Chemical site is a former coke plant that has five lagoons that were used for wastewater treatment and
disposal. The site remedy consists of incineration of approximately 122,000 cubic yards of lagoon five wastes
along with other contaminated materials having contaminant concentrations greater than 1000 ppm. The primary
contaminants are four carcinogenic PAHs (benzo (a) pyrene), chrysene, benz (a) anthracene and dibenz (a,h)
anthracene).
The remedial approach requires that the contaminated materials be screened and segregated prior to incineration.
To address this screening requirement, the RPM has requested that the CRD-LV TSC provide on-site PAH
measurements using the Field Portable Scanning Spectrofluormeter (FPSS).
Because of the uncertainty pertaining to the FPSS's performance in adequately measuring these PAHs, the RPM
sent samples from the site to Las Vegas for analysis. The samples were analyzed and the data provided to the
RPM. Initial response from the Region pertaining to the analyzed data indicates that the FPSS may be utilized at

The TSC was requested by the Regional RPM to provide analytical support. A number of site matrices are
involved. For example, nearby wells contain volatile organic compounds such as trichloroethylene. In addition,
because of the use and disposal of spent solvents and/or paint sludges, the soils are contaminated with high levels
of VOCs and SVOCs and elevated levels of metals. A hydraulic fluid release also complicated the contaminant
profile of both soils and groundwaters.
Because of the large number of tentatively identified compounds (TICs) in the site matrices, the CRD-LV will
receive samples for analysis. The TICs fingerprinting analysis is currently on hold.

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 CRD-LV TSC's X-Ray Fluorescence technology and

The Region IX RPM requested that the TSC provide assistance in evaluating the Allied Signal site as a source of
ground water contamination within the North Hollywood Operable Unit. Specifically, the TSC evaluation will
focus on the following:
• Determine if Allied's soil gas investigation was performed using appropriate field and analytical methodology,
• Perform an independent assessment of the data, and compare these findings with those made by Allied's
contractor,
17
-------
• Determine whether the placement of probes was adequate to characterize source area, and
• Identify data gaps and make recommendations as to whether additional work is necessary.
In addition, the TSC will provide assistance in determining if Allied's soil boring investigation was performed
using appropriate field and analytical methodology, determine whether the placement of borings was adequate to
characterize source areas, attempt to determine whether the findings of the soil boring study are consistent or
inconsistent with the soil gas results, comment on the soil matrix data in light of the subsurface conditions found,
particularly address the likelihood that contaminant releases would have a 'wandering' pattern through the
subsurface, and identify data gaps and make recommendations as to whether additional work is necessary.
In support of this effort, TSC scientist(s) provided the document titled, "Review of Environmental Characterization
Data concerning the Allied Signal, Inc., North Hollywood Site, San Fernando Operable Unit, San Fernando
Valley, California." A Conflict of Interest (COI) problem as identified was resolved during the second quarter of

The Naval Weapons Station Concord is in the north-central portion of Contra Costa County, approximately 30
miles northwest of San Francisco, California. The station operated an ocean terminal facility to transship ordnance
from trucks or railcars to ships and vice versa. The base realignment and closure activities at other facilities in the
west have made Concord a significant military ordnance and transshipment facility on the west coast. The station
encompasses nearly 13,000 acres.
At the present time, RI work plans and field sampling plans for Tidal and Inland Areas have been submitted and
approved by the Navy, State, and EPA. Work will commence on these sites in April, 1995. The work plan for an
Ecological Assessment of the Litigation Sites has been approved to evaluate the remaining effects of hazardous
levels of heavy metals not previously removed by the Navy. This work is also scheduled to begin in April, 1995.
Investigations of groundwater as a contaminant transport pathway into the Tidal Area Sites and Litigation Sites has
been postponed, pending data from soils, sediments, and surface water, and input from the CRD-LV TSC technical

The Hawker Pacific Site is located in North Hollywood, CA. Operations at Hawker have consisted of the
overhaul, repair, and manufacture of aircraft landing gear and flight control equipment. Processes include alkaline
and acid cleaning, vapor degreasing, etching, chroming, and electro-plating of cadmium, nickel and functional
chrome. Additional supporting processes include grinding, painting, and baking of parts, as well as testing of
finished parts using a water-based dye.
EPA believes that the Hawker Pacific Site has been inadequately characterized, especially with respect to the
storage tank release. No soil gas data exists at the site. No groundwater exists at the site. EPA's regional
groundwater monitoring program has interpreted the presence of PCE in groundwater beneath the site. In order to
evaluate the areal and vertical extent of source areas, and to assess the site's contribution to groundwater
contamination, additional data needs to be collected and analyzed.
The TSC is preparing the necessary sampling and data quality plans, specifications, and health and safety plans, to

The Regional RPM requested technical support for the Modesto Groundwater Contamination Superfund Site
located in Modesto, California. The Site consists of a dry cleaner facility which leaked PCE contamination into the
soil and groundwater. It was recently discovered that the groundwater is also contaminated with naturally
occurring uranium. EPA has performed an RI/FS at the site and selected a preferred cleanup alternative which
consists of pump and treat with GAC for groundwater contamination, and SVE for soil contamination. The FS will
now have to be revised to evaluate remedial technologies for the cleanup of radiation related to the naturally
occurring uranium.
20
-------
The objective of this technical support effort is to assist the RPM in selecting the most reliable, efficient and cost
effective remedial technologies to clean up the site. The following three areas are being addressed by the CRD-L V
TSC:
• Identify data gaps in existing data and recommend additional data requirements. The groundwater, soil, and
soil gas, were tested for many different parameters during the RI. Besides uranium the groundwater was also
tested for gross alpha, gross beta, and radium. The soil-soil gas was not analyzed for radiation.
• Identify potential radiation remedial technologies. There are several remedial technologies (or combination of
technologies) which could be utilized for groundwater remediation at the site. Potential technologies
including reverse osmosis, ion exchange, air stripping, and granular activated carbon (GAC).
• Prepare site cleanup cost estimate for each appropriate technology. After the appropriate technologies are
identified a cost estimate will be prepared.
In support of this effort the CRD-LV TSC has provided, "Recommended Data Acquisition for the Modesto
Groundwater Contamination Site" and the report, "Treatment Alternatives Report Modesto Groundwater
Contamination Site." The RPM is currently reviewing these documents. A site visit to audit sampling procedures
was made during the fourth quarter. This effort is still on-going.

Four sites are within the San Fernando Vally (SFV) for inclusion 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 wells
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 RI wells into two categories: those recommended to be sampled quarterly, and 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 having 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
krieging 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 which seem pertinent.

possibly water contamination, the quality assurance/quality control (QA/QC) plan, the S&A plan and all other
methods that have been used to fully characterize the site for remedial purposes. In addition, an assessment of data
needs necessary to satisfy the characterization objectives will be required if past characterization efforts have not
adequately characterized the sites contaminants. This data assessment will involve data interpretation and
recommendations involving statistical and other tests necessary for making decisions concerning the extent of site
contaminants.

the tailings. This effort is critical not only to site characterization and to development of monitoring strategies for
detecting pollution, but also for contributing to appropriate corrective action programs. Also, this effort will
integrate saturated and unsaturated zone monitoring, and site characterization methods used in developing a
monitoring well and sampling network design at mine sites. Assessing site documents and data is in process. A
number of recommendations pertaining to the monitoring design and data assessment was provided to the Region.
This project is still on-going.

The Columbus municipal Electric Utility Boiler, also known as the Columbus Municipal Electric Plant (CMEP),
is located south of downtown Columbus, Ohio. The facility is a power generating plant fueled by coal and
refuse. It has been in operation since 1983 and is owned and operated by the City of Columbus.
In 1987, the US EPA initiated a study of the incinerator ash at CMEP because of the presence of dioxin and
furan isomers associated with incinerator ash. The special study report indicated that incinerator ash contains
dioxin and furan isomers, lead and cadmium. Concentrations of dioxin and furan isomers range from 0.33 ppb
to 2.13 ppb. The highest concentrations were found in top ash from a conveyor belt. A relatively high
concentration (0.84 ppb) was found from a stack scape sample. Dioxins (up to 0.38 ppb) were also found in two
areas in the soil where ash was allowed to accumulate. Lead in the ash was found to exceed EP toxicity limits,
The Regional Risk Assessor has requested that the CRD-LV TSC design a sampling/monitoring strategy and a
quality assurance project plan that would identify the concentration of soil dioxins. The soil dioxin
concentrations that are of interest are 20,40,70 and 100 ppt. The CRD-LV TSC designed a
sampling/monitoring program and finalizing the quality assurance project plan. This project is in process.

ISSUE PAPER
Project Name: Identifying Background
Site: Identifying Background
Site ID:
Type-Lead: Frank Vavra (215) 597-0676
Requested by: Engineering Forum
Lead Scientist: Bob Breckenridge (208) 526-0757, Alan Crockett (208) 526-1574
Start Date: March 1993
Expected Completion Date: July 1994
Revised Completion Date: September 1995
Estimated Budget: $25,000 Total Expenditures: $68,901

Major Contaminants: Metals Total 1st. Qtr. Expenditures: $9,485
Background: Many states have developed requirements for cleanups that are more stringent than risk based levels
and sometimes to background levels. The variability of naturally occurring inorganics may lead Federal/state
representatives to conclude that an area of a site has elevated metals just because of this variability. Establishment of
background based both on site specific sampling and comparison to normal background ranges can help resolve this
issue. Additionally, Natural Resource Trustees may request/require remediation of streams to levels below typical
background levels of man-made substances in developed areas. Areas near roads usually have elevated levels of lead
from leaded gasoline, elevated levels of PAHs from exhaust and asphalt road material, elevated levels of zinc from
oxidation of car metals and elevated levels of inorganics from road salt/ashes. These contaminants are washed into
ditches near the road and accumulate with time. Sites that were used as farmland may have elevated levels of
pesticides and inorganics from fertilizers and pesticides. For example, lead arsenate was the pesticide of choice for
orchards at one time in the past and fertilizers often contain lead which can accumulate in soils. Identification of
representative background levels is often difficult and is complicated by the presence of roads, farms or other land
use.
The CRD-LV TSC was requested by the Engineering Forum to develop a standard process/procedure to identify
background levels of naturally occurring inorganics and typical levels of man-made substances in soils and sediments
that may also be site contaminants. The goal is to produce an issue paper that identifies critical elements that must
be taken to obtain representative background levels and the available processes that can assist in this determination.
Existing documents and sources of information will be reviewed and appropriate material will be referenced. A
planning meeting was held to scope out and generate an outline identifying elements that will be addressed in the
Issue Paper. This outline was completed and reviewed by the Engineering Forum. During the 1st Quarter, FY 94 an
initial draft of the issue paper was completed. The draft issue paper was provided to the Engineering Forum for
review. The TSC addressed the Forum's comments, and prepared the document for peer review. The document has
been peer reviewed and was finalized for publication.

One of the objectives of the CRD-LV TSC is to identify and make available CRD-LV measurement
technologies that are applicable for characterizing contaminants. Documenting the adequacy of these
technologies, the application and their identity requires the development of case studies, fact sheets,
demonstrations and workshops. During this quarter a case study identifying the sampling/monitoring and
analytical methods that were used to characterize mercury contamination at Oak Ridge was printed. In
addition, one four-page fact sheet was developed.
