A geostatistical analysis of the distribution of soil contaminated with polychlorinated biphenyls (PCBs) was conducted to develop a 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 other 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 10 ppm PCBs. The RPM also 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. Reviews of the suggested statistical procedures were completed. Following the review and acceptance of the Work Plan, providing on-site field audits 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. Additional reviews of site documents were completed. Split samples were collected and sent to CRD-LV for analysis. The analysis was completed. The results of the field audit with suggestions and recommendations were sent to the RPM.

Qtr. Expenditures:$0 This six acre site located in Carlstadt, NJ is contaminated with volatile organic compounds, polychlorinated bephenyls (PCBs) and metals. In 1990, Potentially Responsible Parties (PRPs) were ordered to construct an interim remedy to prevent further migration of contaminants from the site. In 1992, construction of the interim remedy was completed. The interim remedy consists of a slurry wall that surrounds the six acre site, a cap that covers the six acres, and a dewatering system that removes water from the top six feet of soil. The PRPs are now performing a focused feasibility study for the final remedy. The PRPs have stated that if the slurry wall should become part of the final remedy, 18,00 cubic yards of soil must remain behind the slurry wall to provide adequate support for the wall. This would require leaving approximately one fifth of the soils inside the slurry wall undisturbed. The CRD-LV Techical Support Center (TSC) has been requested to review the information that the PRPs used to support their position and determine if the PRPs position is valid pertaining to the required amount of soil needed for support. The TSC is reviewing the provided data. The Focused Feasibility Study Investigation Work Plan for the First Operable was received along with design drawings. A geotechnical review was conducted to assess the slurry wall stability results presented by Golder Associates in the FFSI Work Plan. Issues that were evaluated included a check of soil volume calculation, evaluation of soil properties, evaluation of factors of safety selection, review of soil model and method of analysis, and an evaluation of the results, ------- conclusions and recommendations based on the calculations.

Most of the site consists of good quality wetlands with a diverse ecosystem. EPA is currently proposing to amend the Record of Decision (ROD). The EPA released a proposed plan to change the remedy (ROD Amendment) for public comment May 13, 1996. 11 ------- The Remedial Investigation (RI) and Baseline Risk Assessment (BRA), were completed in 1991. The EPA completed the Feasibility Study (FS) in 1992 and signed the ROD in September 1992. The remedy selected included excavation and dredging of an approximate volume of 200,000 cubic yards of tannery waste, soils and sediments and the placement in an on-site landfill. The contaminants at the site are mainly metals (cadium, lead, arsenic, chromium and mercury) with chromium being the primary contaminant and of highest concentrations; and some PAHs. Michigan State University is conducting a study of metal bioavailablity for the PRPs. The Region has requested the CRD-LV TSC to review the approach and data obtained from the Michigan State University study. The TSC received site information and data for review.

The area of concern, at this site located in Ogden, Utah, consists of an approximate 10 acre area of sludgy surface extrusions and contaminated soil. It appears that waste sludge may have been buried over a very large area at this location and the sludge is beginning to surface. The quantity is unknown but appears to be large. The sludge is suspected to contain high levels of organics, heavy metals and possible polychlorinated biphenyls PCBs). The sludge is very greasy and oily, there is a possibility that transformer oil may have been mixed with the sludge, thus the suspected PCBs. The concentrations of contaminants present may constitute a threat to human health or the environment. Access to the waste area is unrestricted. There are no apparent containment structures for the waste. The TSC received site information pertaining to post sampling/monitoring efforts. As assessment of these data was made with a report provided to the Region.

Chemicals and hazardous wastes have been disposed of at Fort Ord. Currently, hazardous wastes are stored at on-site facilities before they are transported and disposed of off site. There are several areas of contamination on site. One of these areas includes three inactive landfills that once were used to dispose of residential and commercial waste. The facility contained leaking hazardous waste tanks, containers of waste oil and various automotive chemicals, chemical storage areas, an oil-water separator, and fueling stations. Another area of on-site contamination is the 14th Engineers Motor Pool. Approximately 5,000 underground fuel tanks, drums of waste oil and other wastes, and sand pits in which waste oil, liquid wastes, and battery acid were disposed of at this area. Fuels were placed into unlined pits and subsequently percolated through the subsurface soil. The TSC was requested to audit raw data generated by a commercial laboratory from samples collected from the Fort Ord Superfund Site.

Qtr. Expenditures: $1,000 The Raytheon Corp. operates as a manufacturer of semiconductor products on this 30-acre site. The Intel Corp. (Mountain View Plant) site, the Fairchild Semiconductor Corp. (Mountain View Plant) site, and this site are being cleaned up simultaneously. All three sites are located in the Middlefield/Ellis/Whisman (MEWE) study area. Various Industrial activities conducted in the area of the site include semiconductor manufacturing, metal finishing operations, parts cleaning, aircraft maintanance, and other activities requiring the use, storage, and handling of a variety of chemicals, particularly solvents. Site investigations at several of these facilities during 1981 and 1982 revealed significant contamination from toxic chemicals, primarily volatile organic compounds (VOCs), in soil and groundwater. The Region requested a review of Section 10.0 of the Operation and Maintenance Plan. Section 10.0 includes statistical methodology for determining the number of confirmatory samples and the evaluation of the confirmatory soil sampling data. The clean up standard is 500 ppb in the soil for outside the slurry wall, and 1000 ppb inside the slurry wall. Confirmation is based on soil data, not soil gas data. The three main areas of concern for review are 1) Are a sufficient number of samples, and boring locations, proposed to adequately characterize the soil and meet the statistical needs to determine if the site is clean after the remediation, 2) is it appropriate to use random distribution of confirmatory sampling locations and 3) is the statistical methodology appropriate and consistent with EPA guidance for evaluating the sample results to determine whether the site is clean? TSC personnel reviewed available data and provided the Region a report with recommended approaches. Also, TSC personnel participated in a number of conference calls with the PRPs. Project Name: San Fernando Valley Basin (SFV) Site: San Fernando SF Site Site ID: Job Order No: Type-Lead: Requested by: Mike Orsinski (415) 744-2249 Lead Scientist A.K.

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 19 ------- 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 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 which seem pertinent. The CRD-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. This project is still on-going.

Qtr. Expenditures: $ 1,600 The RPM requested that the CRD-LV TSC provide technical support in interpreting soil-lead data. The problem is that the PRP is challenging the quantitation of CLP data based on the reported matrix interference for lead results. This interference makes interpretation of the actual concentration of lead on-site very difficult. This issue is important because there is a significant difference (orders of magnitude) between the EPA and the PRPs confirmation sampling results. The PRP believes that their confirmation sampling is more representative of the site and that the site clean-up has met the remediation goals. Conversely, EPA's analysis indicates that significant soil contamination is still present. CRD-LV scientists reviewed the supplied data and conducted some confirmatory analysis. Following the analysis of site samples, the CRD-LV TSC provided the RPM with a report. The analysis of site samples was completed and the data provided to the Region in a report titled, "Determination of Lead, Zinc, and Arsenic on Verdese Carter Park Soil Samples ". Assisting the Region in interpreting the analytical data was completed. Following this initial report the RPM requested assistance in modeling the distribution of lead around the old battery factory. Site-specific meteorological data from the Oakland airport (3.5 miles southwest) for the years 1960 through 1964 were purchased. Digital line graphs showing roads in the area were downloaded from USGS via the Internet. The approximate location of the 100-ft lead oxide mill stack was identified. Relative concentrations within a 2-km radius around the approximate location of the stack were calculated using the ISCLT2 model. Results were plotted as relative concentration isopleths. These preliminary results indicate two potential hot spots. Results also indicate extremely low concentrations would have likely occurred within a 300-m radius of the stack. These preliminary results do not account for lead oxide particle settling velocity or differences in ground surface elevations. 20 ------- The following requirements were completed: 1) procured USGS digital elevation models to determine ground- surface receptor elevations, 2) determined reasonable (or upper/lower bound) lead oxide particle size for input into the ISC air model, and 3) remodeled to obtain refined relative air concentrations and potentiall, ground surface deposition reates. The modeling report titled "Dispersion Modeling of Relative Air Concentration and Ground Depositions at the Verdese Carter Park Site" was completed and provided to the Region. Additional reviews of modeling results were completed. Review comments were provided to the Region.

(M&E) was retained by DuPont Environmental Services, Inc. (DERS) to conduct a soil washing pilot study at the Lake Success Business Park (LSBP) located in Bridgeport, Connecticut. The LSBP site in Bridgeport is owned by Sporting Goods Properties, Inc. (SGP), a wholly-owned subsidiary of DuPont. LSBP is in a interim-status Resource Conservation and Recovery Act (RCRA) facility. In 1990, the site entered into an administrative Consent Order (ACO), pursuant to Section 3008(h) of RCRA, with the Environmental Protection Agency (EPA) for the performance of corrective action activities at the facility. Preliminary evaluations of remedial alternatives indicated that soil washing may be feasible for use as the preferred remediation strategy for the site. The soil washing pilot study was subsequently performed to provide site-specific data for further evaluating this technology, and included evaluation of both soil washing (contaminant concentration by separation of particle sizes and density fractions) and chemical leaching (removal of the contaminants from the concentrated fractions through solubilization of the contaminants into a liquid phase). The RCRA Project Officer requested the TSC to examine the soil washing process and identify an appropriate sampling frequency for determining if the washing process has met the cleanup goals. This effort addressed the statistical requirements necessary for verification and also the appropriate sampling methods. The TSC provided a document titled "Statistical Sampling Design for Evaluating "Clean" Soil Exiting the Soil Wash System Proposed to Remediate the Lake Success Business Park Facility". This document provides guidance for determining the number of samples and their frequency of collection for determining if soil clean-up goals have been met.

Qtr Expenditures:$0 PC&B:$3,000 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 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 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 finalized the quality assurance project plan. Soil samples were collected and analyzed. CRD-LV personnel assisted in data validation and in writing a report that identifies the sampling/analytical procedures and the interpretation of the resultant data. CRD-LV personnel participated in the design strategy for the second sampling/monitoring/analytical phase of this contaminant characterization project. The second phase sampling effort was completed. The TSC is currently evaluating the quality of the analytical data from the second phase analyses.

Expenditures: $49 27 ------- The Characterization Research Division-Las Vegas (CRD-L V) Technology Support Center (TSC) was requested to provide an engineering review and written comments of a technology evaluation plan and site work plan for the Philip Environmental Georgetown, Washington facility. The purpose is to provide a review of the remedial technology proposed for a pilot study at this facility. Benzene, ethyl benzene, toluene and xylene (BETX) and chlorinated solvents have been found in the shallow and intermediate aquifers. Contaminants in the intermediate aquifer are primarily dense chlorinated solvents. Because of the observed concentration of trichlorethene (TCE) at some locations, dense non-aqueous phase (DNAPL) TCE may be present in the western area of the north field in the intermediate aquifer. Because of the ^ 'tigraphy of the intermediate aquifer it is likely that this DNAPL, if present, consists of a residual phase rather than pools oi tree phase TCE. Phenolic compounds are also present in the shallow aquifer at concentrations exceeding cleanup standards. The TSC us currently reviewing the provided data.

Qtr. Expenditures:$4,416 The Federal Facilities Forum requested the CRD-LV TSC to prepare an Issue Paper addressing the current "State of Technology" with regards to "On-Site Analytical Methods" for identifying explosive contaminants in soils. In addition, this issue paper discusses 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 pants, Naval ordnance plants, Army deports, Naval ammunition depots, Army and Navy proving grounds and burning grounds. This issue paper will provide guidance to Remedial Project Managers for the use of on-site methods to screen explosives. Also addressed are the explosive and propellant compounds targeted by high performance liquid chromatography (HPLC) methods, including EPA SW-846 Method 8330, the primary method required by EPA Regions for laboratory confirmation. This paper does not address primary explosives or initiating compounds, such as lead azide, lead styphnate, or mercury fulminate, which are extremely unstable and present a substantial safety risk at any concentration. Primary explosives are used in small quantities in fuses or detonators in munitions, with a much larger quantity of secondary- explosives. In addition, this paper is not intended to serve as a guide for the analysis and sampling of unexploded ordnance, bulk high explosives, or where secondary explosives concentrations detonation hazard. An abstract of the paper was accepted for presentation at the EPA's Twelfth Annual Waste Testing & Quality Assurance Symposium, July 23-26, Wahington, D. C. An eight page paper entitled "Guidance for Characterizing Explosives in Contaminated Soils:Sampling and Selecting On-Site Analytical Methods" will be published in the proceedings of the meeting. 31 ------- The CRD-LV TSC received initial review comments from the Federal Facilities Forum members. These comments were addressed by the authors. The issue paper was ORD Peer reviewed and is currently being formatted for CRD-LV sign off and concurrence. ISSUE PAPER • Project Name: Statistical Issue Paper Site: Lognormal Distribution Site ID: Type-Lead: Requested By: Kenneth W. Brown Lead Scientist: A. K. Singh (702) 435-3731, Max Engelhardt (208) 526-2100 Start Date: July 1996 Expected Completion Date: January 1997 Revised Completion Date: Estimated Budget: $5,000 Total Expenditures: $ 1,221 Revised Budget: $ Total FY96 Expenditures: $ 1,221 Major Contaminants: Total 4th Qtr. Expenditures^ 1,221 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 the 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 CRD-LV 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. ISSUES • Project Name: Range Site: Range Rule Site ID: Type-Lead: Requested by: Doug Bell (202) 260-8716 Lead Scientist: Alan Crockett (208) 526-603 32 ------- Start Date: July 1996 Expected Completion Date: February 1997 Revised Completion Date: Estimated Budget: $ 10,000 Total Expenditures: $576 Revised Budget: $ Total FY96 Expenditures: $576 Major Contaminants: Explosives Total 4th. Qtr. Expenditures: $576 The OSWER Range Rule Project Officer requested that TSC personnel participate in evaluating DOD approaches dealing with the Range Rule. This request resulted in part due to the CRD-LV TSC's involvement with the "Explosives in Soil" Issue paper. The U.S. Department of Defense (DOD) developed a Range Rule that identifies a process for evaluating appropriate response actions on closed, transferred, and transferring ranges. Range Rule response actions address public safety, human health, and the environment. As part of the Range Rule process, DOD had developed a three-tiered risk evaluation methodology for military ranges containing unexploded ordnance (UXO). This Range Rule risk methodology (RRM) is composed of three components; the qualitative risk evaluation (QRE), the streamlined risk evaluation (SRE), and the detailed risk evaluation (ORE). A military range is defined as any designated land, air, or water area used for training with military munitions, or any area used for munitions research, development, testing, or evaluation. Land previously used as military ranges potentially poses a risk to public safety, human health, and the environment, because UXO may remain on site. UXO is defined as military munitions that have been primed, fused, armed, or otherwise prepared for action, and have been fired, dropped, launched, projected, or placed in such a manner as to constitute a hazard to operations, installations, personnel, or material. UXO may remain unexploded either by malfunction, design, or other cause. Current fiscal realities demonstrate the need for a system to determine priorities for conducting response actions. The RPM will be used to qualify and quantify each range's risk to assist DOD in prioritizing response actions. The CRD-LV's sampling and site characterization responsibilities include: 1. Determine level of effort (LOE) needed to characterize and delineate contamination on the range (within buffer zones, cleared areas) and off-range. Explaining the amount of information needed to determine LOE This would presumably involve deciding need for statistically based sampling or selective sampling, sample size, discrete vs composite samples. 2. Recommending models to predict off-site or buffer zone contamination levels in transported media (groundwater, surface water, or air) at ranges where sampling is prohibited because of explosive hazard. 3. Establishing a protocol for the above using range scenarios with guidelines for site-specific factors. The CRD-LV TSC have provided some preliminary comments on some of DOD's suggested sampling/monitoring approaches. 33 ------- COORDINATION Project Name: Superfund Coordination Site: Superfund Coordination Site ID: Type-Lead: Requested by: Ken Brown Lead Scientist: Phil Malley (702)897-6644/Alan Crockett (208)526-1574 Start Date: On-going October 1995 Expected Completion Date: September 1996 Revised Completion Date: Estimated Budget: $100,000 Revised Budget: $ Major Contaminants: N/A Total Expenditures:$91,671 Total FY96 Expenditures:$91,671 Total 4th.
