Qtr. Expenditures: $500 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-sitefield audits for the "Preliminary Soil/Sediment Screening/Sampling" of the Phase IARI activities conducted by the PRPs was required.

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). 12 ------- 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 this site. The TSC completed an assessment of a sampling/monitoring approach. Recommendations pertaining to the sampling/monitoring approach was provided to the Region.

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 TSCs X-Ray Fluorescence technology and equipment to measure site contaminants. The CRD-LV TSC is continuing to support this effort. • Project Name: Oronogo-Duenweg Site: Oronogo-Duenweg SF Site Site ID: Type-Lead: Fund Requested by: David P.

Qtr. Expenditures:$51,249 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, • 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. 16 ------- 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 FY95. A meeting between Region 9, NEIC, INEL and CRD-LV personnel was held to address and identify further assessment needs. These needs included additional assessment of site data and to testify in court concerning contaminant sources.

Qtr. Expenditures:$6,182 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. Limited groundwater data exists for the site. EPA's regional groundwater monitoring program has suspected 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 proposed the necessary sampling and data quality plans, specifications, and health and safety plans, to conduct site characterization requirements. This characterization effort was to consist of drilling and completing two monitoring wells, sampling soil gas and groundwater and modeling VOC transport in the Vadose Zone. Prior to initiating this project the PRPs agreed to a settlement with EPA.

Qtr. Expenditures: $0 19 ------- 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. 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-LV 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. • 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 FY95 fourth quarter. This effort is still on-going. Project Name: San Fernando Valley Basin (SFV) Site: San Fernando SF Site Site ID: Job Order No: Type-Lead: Requested by: Ned Black (415) 744-2253 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 20 ------- 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. 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. Project Name: Verdese Carter Park Site: Verdese Carter Park Superfund Site Site ID: Job Order No: Type-Lead: Requested by: Michael E. Bellot (415) 744-2364 Lead Scientist: Mike Abbott (208) 526-8596 Start Date: May 1994 Expected Completion Date: December 1994 Revised Completion Date: August 1996 Estimated Budget: $40,000 Total Expenditures: $22,747 Revised Budget: $ Total FY96 Expenditures: $2,440 Major Contaminants: Metals Total 2nd. Qtr. Expenditures: $2,440 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 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 with roads. These preliminary results indicate two potential hot spots, one approximately 1 km north-northwest. 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. 21 ------- The following refinements are needed and underway: 1) procure USGS digital elevation models to determine ground-surface receptor elevations. 2) determine reasonable (or upper/lower bound) lead oxide particle size for input into the ISC ay- model, and'3) remodel to obtain refined relative air concentrations and potentiall, ground surface deposition reates. Results will be documented in a final report.

Qtr Expenditures:$5,000 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 26 ------- (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 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.

Qtr. Expenditures:$19,300 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 will discuss appropriate sampling/monitoring approaches that may be implemented to characterize these types of contaminants. 30 ------- 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 initial draft of this paper was provided to the Federal Facilities Forum for their review. 31 ------- COORDINATION Project Name: Superfund Coordination Site: Superfund Coordination Site ID: Job: Order No: 226 10101 Type-Lead: Requested by: Ken Brown Lead Scientist: Phil Malley (702)897-6644/Alan Crockett (208)526-1574 Start Date: On-going October 1991 Expected Completion Date: September 1996 Revised Completion Date: Estimated Budget: $ 100,000 Total Expenditures:$34,629 Revised Budget: $ Total FY96 Expenditures:$34,629 Major Contaminants: N/A Total 2nd.
