The 9,000-acre Loring Air Force Base located in Maine has operated as an active military installation since 1952. An estimated 1,200 people obtain drinking water from wells within 3 miles of hazardous substances on the base. The nearest well is less that 500 feet from where transformers were buried. Hazardous wastes generated on the base include waste oils, fuels cleaned from aircraft and vehicles, spent solvents (many are chlorinated organic chemicals) polychlorinated biphenyls (PCBs), and pesticides. Historically, wastes have been burned or buried in landfills. There are on-site landfills, some of which are old gravel pits. Landfills #2 and #3 were used for disposal of hazardous wastes from 1956 to the early 1980s. Tests of monitoring wells indicate that the groundwater on the base is contaminated with volatile organic compounds (VOCs) such as methylene chloride, trichloroethylene (TCE), and carbon tetrachloride and heavy metals including barium. Soils in the Flightline Area contain significant amounts of fuel, oil, and various VOCs. The TSC received a "Technical Memorandum Operable Unit (OU) 12 Annual Report Statistical Methodology, Loring AFB" dated November 20, 2001. Following a review of this document, the TSC provided comments and recommendations to the RPM. Project Name: Camp Edwards (Otis AFB) Site: Military Reservation (Massachusetts) S. F. Site Site ID: Type Lead: Requested by: Mike Jasinski (617) 918-1352, Paul Marchessault (617) 918-1388 T. Borci (617) 918-1358 Lead Scientist: Bob Starr (208) 526-0174, Jeff Sondrup (208)526-8396, Art Rood (208) 526-1678 Start Date: July 1998 Expected Completion Date: April 1999 Revised Completion Date: August 2002 Estimated Budget: $40,000 Total Exps:$84,633 PC&B:$3,300 Revised Budget: $89,000 Total FY02 Exps:$932 PC&B:$0 Major Contaminants: Organics Total 1st Qtr. Exps:$932 PC&B:$0 The Regional RPM requested that the ESD-LV TSC provide assistance in evaluating the feasibility of implementing natural attenuation as the remedial remedy for groundwater contamination at this site. The Otis Air National Guard Base (NGB) and Camp Edwards covers approximately 3,900 acres on a 22,000- acre parcel of land, today known as the Massachusetts Military Reservation (MMR). In 1984, the U. S. Geological Survey detected contaminants in the monitoring wells downgradient of the plant. In 1983 and 1984, the Air Force detected volatile organic compounds (VOCs) in on-site monitoring wells near the Base Landfill and Current Fire Training Area. Monitoring by the Air National Guard and the State Department of Environmental Quality has detected VOCs in more than 200 private wells. TSC reviewed the Focused Feasibility Study for Landfill-1 (draft) to address several issues including evaluating the evidence that: natural attenuation of chlorinated ethenes was occurring in the aquifer downgradient of Landfill-1, natural attenuation would be sufficient as a sole remedy for managing the plume of contaminated ------- groundwater emanating from Landfill-1, active remedial measures (such as pump-and-treat) would inhibit biodegradation of chlorinated ethenes, decreasing concentration trends are the result of installation of a landfill cap instead of natural attenuation, and finally, reviewed the cost estimates of various remedial alternatives. In spite of the extremely short review period, the TSC (INEEL) participated in two meetings at the site with regulators and the Air Force, as well as numerous tele-conferences in which natural attenuation and other remedial alternatives were discussed. At the request of Region I, a series of documents was provided that describe a groundwater remediation program at the INEEL Test Area North facility. The TSC reviewed the addendum to the focused feasibility study for Landfill-1 and participated in a number of tele-conferences and attended a meeting to discuss TSC comments and suggestions. The RPM provided the TSC with extraction/treatment system data for review. The TSC received a request to assist in the establishment of conservative soil concentration for explosive residues and other contaminants based on leaching to groundwater. An evaluation of the SESOIL Model was completed. In addition, a data report titled "Soil Action Levels for Massachusetts Military Reserve Northern Impact Area" was provided to the Region. The TSC was requested to review DoD's site specific fate and transport measurement Task 2000. The TSC completed a review of the modeling portion of the RI for the chemical spill-19 (CS-19) area. The TSC calculated some additional soil screening concentrations that were provided to the Region. TSC reviewed "Contaminant of Concern Identification Demolition Area 1" and the "Draft Modeling Strategy for the Camp Edwards Impact Area Groundwater Quality Study." The TSC responded to a request dealing with a fate and transport model and attenuation factors and provided the report titled "Contaminant of Concern Identification for Demolition Area 1 Soil Operable Unit of the Camp Edwards Impact Area, Massachusetts Military Reservation, Cape Cod, MA." The TSC received some additional information from the Region pertaining to RDX soil cleanup levels. Based on this information the TSC calculated additional cleanup levels based on the dispersion and dilution of site contaminants. • Project Name: Ottati Site: Ottati and Goss/Kingston Steel Drum S.

Expenditures:$400 The RPM requested that the BSD, TSC provide assistance in designing and identifying sampling methodologies for sampling hummocks. The Ottati & Goss/Kingston Steel Drum site in Kingston, N.H. is situated on 35 acres, contains a 1-acre parcel in the southwest portion that was leased and known as the Ottati & Goss (O&G) site and a 6-acre Great Lakes Container Corporation (GLCC) site consisting of a rectangular parcel bordered on the east by Route 125. From the late 1950s through 1967, Conway Barrel & Drum Company (CBD) owned the site and performed drum reconditioning operations on the parcel of land later owned by the Great Lakes Container Corporation. The reconditioning operations included caustic rinsing of drums and disposal of the rinse water in a dry well nearby. ------- The groundwater, surface water, and soils are contaminated with volatile organic compounds (VOCs). The on- site soil also contains polychlorinated biphenyls (PCBs), metal, and acids and base/neutral compounds. The TSC participated in a conference call and provided comments and recommendations pertaining to a proposed sampling plan. The TSC reviewed and provided comments pertaining to the sampling plan and quality control sections of the 90% design contract specifications. In addition, a report titled "Assessment of Arsenic Distribution in Ottati and Goss Soils" was completed and provided to the Region. The TSC reviewed the sampling quality control and wetland restoration sectors of the 100% design contract specifications document. A number of letter reports on this review was provided to the Region. Also, several issues, including the arsenic report, were discussed with the RPM. The TSC reviewed and provided comments to the RPM on the "Compendium of Quality Assurance Project Plan Requirements and Guidance." The TSC participated with the Region and USAGE in discussions on the "Sampling Procedures and Laboratory Services" of the Ottati & Goss 100% design document.

Project Name: Savage Well Site: Savage Well Municipal Water Supply OU-2 S. F. Site Site ID: Type Lead: Requested by: Richard Goehlert (617) 918-1335 Lead Scientist: Lance Peterson (208) 528-8718 x!70, Bob Starr (208) 526-0174 Start Date: May 1999 Expected Completion Date: December 1999 Revised Completion Date: January 2002 Estimated Budget: $20,000 Total Expenditures:$29,226 Revised Budget: $30,000 Total FY02 Expenditures:$2,100 Major Contaminants: Organics Total 1st Qtr. Expenditures:$2,100 The RPM requested that the ESD-LV TSC provide assistance in reviewing aquifer models that are and/or will be used to determine appropriate remedial approaches. The Savage Well site covers about 30 acres west of the center of Milford, NH and consists of a municipal well. 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 form 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. Investigations 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 VOCs, including 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. As previously identified the TSC has been involved at OU-1 with the "Surfactant-Enhances Aquifer Remediation of PCE at Neutral Buoyancy" Project." The PRPs have modeled the Savage Well aquifer and evaluated several remedial scenarios. They have come to the conclusion that monitored natural attenuation remedy will result in a clean aquifer in about the same time as ------- an engineered remedy. This does not seem to make sense given the complexity of the aquifer and the broad extent of contamination in OU-2. OU-1 is a fund lead slurry wall, with pump and treatment system, SVE air sparging, and air stripping. OU-2 is a dissolved plume downgradient from the OU-1 area. Numerous reports were received on hydrologic modeling of Savage Well OU-2 site. The hydrologic site conceptual model review and a numerical model review were completed. Questions and comments were formulated. The TSC has performed an initial review on the QST Draft Modeling report and the Remedial Design Report. The modeling review was completed and the report titled "Comments Regarding Modeling and Interpretations on the OU-2 Savage Well Site" was provided to the Region. The TSC received the 1999 USGS groundwater modeling report. The report was reviewed and was considered satisfactory. Discussion with the RPM pertaining to the transport models "ModFlow" and ModFlow/MTSD occurred. The TSC reviewed the document "An Evaluation of June and August 2000 Sampling Results: Biotic Transformation of Chlorinated Organic Compounds Within the Extended Plume, Savage Well ESE." A number of conference calls pertaining to modeling questions were held with the RPM. Following a review of an ES&E Nov. 2000 Draft Report, the TSC provided the Region with the report titled "Draft Evaluation of June and August 2000 Sampling Results: Biotic Transformations of Chlorinated Organic Compounds Within the Extended Plume." The TSC responded to a request from the RPM pertaining to the use of diffusion sampling procedures to identify vertical contaminant zones in long-screened wells. • Project Name: Union Chemical Site: Union Chemical Company S.

Expenditures:$ 1,600 The Regional RPM requested that the ESD-LV TSC provide assistance in reviewing a closure plan for groundwater. The Union Chemical Company, located in South Hope, Maine, occupied approximately twelve acres in a rural residential area, with most of the activities occurring within a two-acre portion of the property. The business began operations in 1967 as a paint stripping and solvent manufacturing business. The company subsequently expanded to include recycling of used stripping compounds using a distillation unit. The operation further. expanded, first with an on-site boiler and the fluidized-bed incinerator to treat the hazardous wastes. Groundwater and surface water contamination was first discovered in 1979. EPA and Maine DEP performed a removal action in 1984, taking offsite the contents of over 2000 55 gallon drums and 28 liquid storage tanks. Maine DEP closed the hazardous waste treatment at the site in June 1984. The RI, performed in 1987 - 1988, delineated contamination horizontally and vertically throughout the two-acre portion. The FS established depths for remediation, typically to the water table for most of the site, and six feet beneath the water table in an area between a leach field and interceptor trench. ------- The TSC received a number of documents (i.e. "Declaration for the Explanation of Significant Differences" and is currently reviewing them.

Expenditures:$2,500 The Regional RPM requested that the ESD-LV TSC provide assistance in reviewing a remedial design work plan for a bioremediation system for contaminated bed rock. This 11-acre site, located in Fairfield Township, N. J., is on an extensive 100-year flood plain of the Passaic River. From the 1950's to 1984 septic wastes were deposited in unlined lagoons and later in steel holding tanks. EPA investigations indicated on-site soil and a municipal well were contaminated with VOCs, PCBs and metals. Groundwater remains contaminated because of a TCE-contaminated plume which extends 4,000 feet toward the river. A second remedial action addresses off-site groundwater contaminated with VOCs including TCE. The selected remedy includes pumping and treatment of off-site groundwater using air stripping with off-site discharge to the river; installation of a drainage system to eliminate surface exposure to contaminated groundwater; sealing groundwater wells; and groundwater monitoring. The TSC has not received the remedial workplan. • Project Name: Cornell Site: Cornell Dublier S F.

From 1948 to 1978, the company carried out electroplating, dyeing, and painting operations at the site. The contaminated areas consist of three acid vats, a sludge drying lagoon, two leaching basins, a number of finishing vats, and a basin for holding storm water. In 1977, the State found Liberty in violation of the discharge limits of its permit. Liberty was ordered to clean up the site in 1978, but did not do so. As an initial action, the company, under State supervision, removed contaminated soils and sledges from the leaching basins, the storm water basin, and the sludge lagoon. Groundwater and soils are contaminated with heavy metals including cadmium and chromium. People who drink water from contaminated wells may be at risk. 10 ------- Following a number of conference calls with the RPM the TSC provided information on "isotopic signatures" via the document titled "Literature Review: Stable Isotopic Signatures for Chloroethane Source and Progress Identification."

The Sharon Steel Corporation Farrell Works Disposal Area (the "site") is an area of about 400 acres located in Mercer County in Western Pennsylvania, within a few hundred feet of the Ohio/Pennsylvania border. The site is southwest of the former Sharon Steel Corporation Farrell Works, and is bordered on the east by the Shenango River. The Sharon Steel Corporation used the area to dispose of blast furnace slag, electric arc furnace slag, basic oxygen furnace slag, and sludge beginning about 1900. From 1949 to 1981, millions of gallons of spent pickle liquor acid were dumped over the slag. It was thought that die acid would partially evaporate and then be neutralized by the carbonates in the slag. In actuality, ground water contamination resulted. The site is located in the flood plain of the Shenango River, and there are several wetland areas on site. This on-going effort involved the updating of the PROUCL program such as: • including test of normal and lognormality • Small samples - Shapiro Wilk's test/normal probability plot • Large sample - Kohnogrov-Smirnov's test/normal probability plot, and • for lognormally distributed data sets, include a 99% Chebychev inequality based upon minimum variance unbiased estimates.

The 3-acre Distler Brickyard site in West Point, Kentucky is located on a 70-acre abandoned brick manufacturing plant property that operated from the late 1800s until the mid-1970s. In 1976 the property was leased by Kentucky Liquid Recycling Inc., which began transporting waste to the brickyard property. Waste disposal was contained at the site until 1979. There were approximately 2,300 drums on the site, 1,550 of which contained various liquids, sludges, and solids. Spillage from the deteriorated drums killed grass, trees, and birds on the site. A contaminated groundwater plume is located beneath the site and could threaten the city drinking water wells and the Ohio River. Specific contaminants detected in groundwater and on-site soils include various volatile organic compounds (VOCs) and heavy metals including lead from waste disposal activities. Potential health threats include direct contact with, or accidental ingestion of, contaminated soils and groundwater. The TSC received, and reviewed, three documents pertaining to groundwater remediation. Comments and recommendations were provided to the RPM. The lead scientist participated in a technical meeting with the RPM, USGS, and Kentucky State personnel in June. It was agreed at the meeting that additional field data are required to fully evaluate potential biodegradation at the site. The TSC is to prepare the FSP, and the USGS will lead the collection of additional field data. TSC will interpret the new field data and make a recommendation for further remedial action at the site. Distler Brickyard support is expected to continue into FY 2000 and may include a cooperative effort with USGS, EPA, State of Kentucky for design, construction and operation of an "enhancement" to the existing remedy. Several conferences calls were conducted with USGS and the Region to iron out the details of a schedule for the sampling event. Sampling activities at the Distler site to be conducted by the USGS are scheduled for October 18-22 and will include 11 wells. Samples will be sent to the EPA Water Quality Laboratory in Athens, Georgia for analysis. Data analysis will be performed by TSC staff. The TSC and USGS completed the draft "Field Sampling Plan for the Distler Brickyard". TSC and USGS prepared a status update on field activities for the RPM. The update discusses the sampling activities conducted, problems encountered in the field, recommendations for improving site conditions, and a preliminary schedule for completion of the final report. A conference call was held to finalize this report with Femi Akindele. The TSC completed and delivered the report titled "October 1999 Groundwater Sampling and Data Analysis Distler's Brickyard, Hardin County, Kentucky". The TSC provided the following documents to the Region: "Final Field Sampling Plan" and "Proposed Activities for Fine Grained Alluvium (FGA) Sampling." Following the collection and analysis of site samples and data the TSC provided the report titled "Summary of Groundwater and Soil Gas Collected June-August, 2000 Distler Brickyard Superfund Site, Kentucky." A meeting with the RPM occurred on October 11, 2000 at the Regional Office and at this meeting presented the results obtained from groundwater and soil gas sampling activities conducted at the site June-August 2000. Possible final remedial response actions were presented to EPA, however, a final decision for the site was deferred pending completion of the final report. The report titled "June-August 2000 Groundwater and Soil Gas Data Analysis, Distler Brickyard Site, Hardin County, Kentucky" was completed on November 30, 2000. This report recommended the investigation of an innovative enhanced bio-remediation technology for remediation of remaining chloroethene contamination at the site. Conference calls were conducted in January and March 2001 with USGS, EPA, and the State of Kentucky to discuss TSC recommendations.

The site property consists of 85 acres, and slopes slightly from north to the southeast. The main building, from which lens manufacturing operations were conducted, is situated on a 34-acre portion of the site property. Approximately fifty-one additional acres, designated primarily as wetlands, lie to the east and southeast of the main building. The site was used by Textron, Inc. (from 1960 until 1985) and Shuron, Inc. (1995 until 1991) as an ocular lens manufacturing facility. Wastewater generated from manufacturing processes conducted on the site contained volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs) and metals. Wastewater was discharged from the main building to the wastewater settling lagoons, which lie east of the building. Wastewater from the settling lagoons was discharged to the northern drainage ditch, which drained to the wetland, east of the main building. Sediment from the lagoons was transferred to the solids ponds located south of the settling lagoons. At the request of the RPM, two TSC scientists met at the site in April 2000. The TSC reviewed the RI report, the ROD, and the baseline groundwater report and provided comments in the letter report titled "Review of the Groundwater Sampling Plan for the Shuron Superfund Site, Barnwell, South Carolina."

Exps:$219 PC&B:$600 The RPM requested that the BSD, TSC provide assistance in reviewing site documents and possible modeling subsurface contaminants. The area around this 0.75-acre site, located in Houston, Texas, is a mix of residential, commercial, and light industrial facilities. Approximately 2,000 residents and 100,000 other people move within a one-mile radius of the site on a daily basis due to recreational activities associated with the area. The site operated as an electrical transformer salvage and recycling company between 1971 and 1978, and as a chemical recycling and supply company from 1979 through 1980. The first documented investigation of this site took place during the fall of 1971 when the City of Houston Water Pollution Control Division noted that the workers at Industrial Transformers poured oil out of electrical transformers onto the ground during transformer dismantling. A technical assessment of the site, commencing in January 1986, indicated the presence of PCB contamination has been confined to the top two feet of soil. The highest concentrations of PCBs were found in the middle of the site. TCE has migrated deeper than the PCBs and away from the site. Residual TCE remaining in the surface soil will be remediated along with the PCB contaminated soils. The TSC reviewed a number of documents and provided initial comments and recommendations to the RPM. TSC personnel met with the RPM, and the State of Texas staff in Houston, TX for a site visit and a more definitive discussion as to what assistance the TSC will provide. Following the site visit, the TSC provided a list of technologies that may be useful at the Sol Lynn site and provided information about dissolved oxygen (DO) measurements. The TSC reviewed and provided comments on the amended work plan in particular to the fate and transport modeling issues. The TSC reviewed and provided comments and suggestions pertaining to the "Supplemental RI/FS Study" and provided information on the required groundwater modeling parameters. In addition, the TSC received, and reviewed, the "Field Sampling and the Data Management Plans." The TSC is currently doing the sub-surface modeling for the Region. Additional data (i.e., well survey and water level data) was received by the TSC and was used to update the preliminary groundwater flow model. The TSC received reviewed and provided comments pertaining to the amended work. The TSC consulted with the site contractor, Terra Tech, concerning the relocation of a well that could not be located as previously agreed due to interference with an existing powerline. Effort was devoted to examining the transport codes to be used in the planned modeling to increase their computational effort through parallelization. The TSC is waiting for the updated maps of well locations and site features. A number of conference calls and discussions with the RPM pertaining to aquifer hydraulic properties were conducted.

This 66-acre site located in Houston, Texas is a mixture of residential, commercial, and industrial properties. The site was used as a wood preserving and coal tar distillation facility from 1910 to 1962. The wood preserving facility consisted of an operation area, a drip track, and treated and untreated wood storage areas. The operation area included wood-treating cylinders, chemical storage tanks, and a waste water lagoon. Creosote and metallic salts were used in the operation. The primary contaminants of concern affecting the groundwater, soil and sediment are VOCs including benzene, toluene, and xylene, other organics including PAHs; and metals including arsenic, chromium and lead. The TSC received, and reviewed, the report "Verification of Groundwater Fate and Transport Evaluation" dated July 2000. The TSC also reviewed comments by Roger Lee on the "verification" report. In November the TSC provided the Region with a report titled "Review of Verification of Groundwater Fate and Transport Evaluation-South Cavalcade Superfund Site, Houston, Texas." In summary, source control or removal is usually a prerequisite for selection of MNA. Creosote present as a DNAPL at this site would be expected to persist for decades or longer. Therefore, the plans for removal or long term management of this material are an important part of a remedy, but are not addressed in this document. The TSC participated in a number of conference calls with the Region pertaining to TSC comments and recommendations. Additional support is anticipated.

The 25-acre Texarkana Wood Preserving Company site, located in Bowie, 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. Past efforts by the TSC included evaluation of previously collected data. The TSC utilized Geostatistics for assisting the Region 29 ------- in identifying the geographical distribution of site contaminants. The TSC evaluated monitoring data and attended meetings at 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 approached was completed. Due to a change in the remedy the Region has requested additional assistance in updating the modeling effort that the TSC provided in 1999. The 1999 provided product was "Groundwater Fate and Transport Modeling for Texarkana Wood Preserving Company S.F. Site." The TSC is currently reviewing additional groundwater data. REGION 7 • Project Name: Asarco Site: Asarco Omaha Facility S. F. Site Site ID: Type Lead: Requested by: Don Bahnke (913) 551-7747 Lead Scientist: Mike Abbott (208) 526-8596, A. K. Singh (702) 895-0364, Bill Cole (702) 897-3255 Start Date: September 1998 Expected Completion Date: February 1999 Revised Completion Date: July 2002 Estimated Budget: $ 18,000 Total Expenditures:$65,132 Revised Budget:$80,000 Total FY02 Expenditures:$9,866 Major Contaminants: Lead Total 1st Qtr. Expenditures:$9,866 The RPM requested that the ESD-LV TSC provide assistance in modeling ground deposition rates relative to air contaminant concentrations. The Asarco Omaha facility refined lead bullion and lead drosses. Refinement was achieved using traditional pyro-metallurgical processes including addition of metallic and non-metallic compounds to molten lead to remove impurities. The Omaha plant produces refined lead and speciality metal by-products including antimony-rich lead, bismuth, dore' (silver-rich material) and antimony oxide. Although fundamentally classified as a primary lead refinery (not lead smelter), the Omaha plant is the only facility in the United States, and one of only a few such facilities in the world, designed to process lead bullion containing recoverable amounts of several different metals. As a result, the facility employs a complex array of both traditional and unique pyrometallurgical processes which are carried out as batch operations. This facility was constructed in the early 1870s and is currently closed. The TSC review of site and metallurgical data deposition was completed. Following this review an initial model was completed. This model included plots of relative annual wet and dry deposition rates from the 180' "Black Stack" covering the periods 1984 through 1990. Deposition modeling runs have been completed for the 180' stack. A 310' stack is soon to be evaluated. Once all the modeling is completed, a report will be written and provided to the Region. The final report "Dispersion Modeling of Atmospheric Deposition Patters Around the Asarco Omaha Lead Refinery" was completed and sent to the RPM. This report details the methods and results of lead fallout modeling for both the 180-ft. Black Stack and an old 310-ft. Stack. There was some follow-up work completed comparing the modeling results with a map of actual soil concentrations. Comments 30 ------- pertaining to the comparison of soil concentration with the modeling results were provided to the RPM. The TSC was requested to provide geostatistical support by kriging soil lead concentrations on and in the vicinity of the smelter. The TSC completed the kriging and provided maps and associated overlays. In addition, the TSC provided recommendations for additional sampling locations that would improve the kriged results. Based on these maps the RPM requested assistance in identifying specific sampling locations. The TSC provided the Region an "all properties kriged map identifying six locations where additional samples should be collected." The TSC provided the Region with a table identifying properties on and near the site that exceeded 400 mg/kg of soil lead at one mile increments. Also provided were figures and tables delineating the percentage of properties exceeding 400 mg/kg of lead on 4 cardinal directions in 1-mile increments. The TSC received additional data completed geostatistical analysis and provided the Region with kriged maps and overlay of soil lead concentration. The TSC is currently evaluating arsenic soil data for possible kriging. Project Name: Big River Site: Big River Mine Tailing S. F. Site Site ID: Type Lead: Requested by: Bruce Morrison (913) 551-7755 Lead Scientist: Mike Abbott (208) 526-8596 Start Date: April 1997 Expected Completion Date: October 1997 Revised Completion Date: January 2002 Estimated Budget: $30,000 Total Expenditures^ 105,727 Revised Budget:$ 110,000 Total FY02 Expenditures:$4,867 Major Contaminants: Inorganics Total 1st Qtr. Expenditures:$4,867 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 fomer mining region, is about 70 miles south of St. Louis and is often referred to as the "Old Lead Belt". The region (approximately 110 square miles) contains numerous tailings ponds and piles. St. Joe Minerals Corporation operated the site. There is disposed lead, cadmium, and zinc rich mine tailings over approximately 600 acres in 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 the site in 1977, when an estimated 50,000 cubic yards of tailings slumped into the Big River during a heavy rain storm. 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 31 ------- 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 was reviewed by the Region and the Agency for Toxic Substances and Disease Registry. The report was finalized and developed into an external report and a journal manuscript. The final publications will include a comparison of the modeling results with surface soil sampling data recently obtained. Initial examination of these sampling results indicate very good agreement with model predictions. Finalization of the modeling report was completed, after receiving review comments from the RPM. Review comments were received. The report was finalized. The RPM requested that the TSC provide assistance as needed to the PRP sub-contractor (TRC, Inc.) in using modeling results for the PRP's current site assessment. This benefits EPA by promoting consistency and coordination between the PRP and EPA's site assessment methods and assumptions. On September 29th, Gayle Hoffnagle of TRC Inc., was sent a zipped file containing the six 1-year St. Louis FDM met files that were used in the Big River site modeling and an Excel file containing Desloge air monitoring (lead only) data that was built from hard copies of Shell monitoring reports. The TSC Task Lead and the TRC Inc. personnel have had a number of discussions pertaining to a number of modeling issues. The TSC received a request to review a Deposition Sampling Protocol developed by the PRP subcontractor, TRC. That protocol proposed that downwind deposition of wind suspended lead be measured using oil-coated filters in samplers located downwind of two tailing sites. The TSC completed the review of the deposition sampling protocol and provided comments to the Region. In December the TSC was requested to review a new air sampling plan submitted by TRC. The plan was reviewed with comments and suggestions provided to the Region. The TSC completed some lead/soil analysis and provided the Region with the report titled "Big River Superfund Site In Vitro Soil Extraction." The TSC completed some data assessment analysis pertaining to the distribution of lead from the source. The RPM sent the TSC an additional sample for bioavailable lead analysis. The sample was analyzed. The analytical results are currently being assessed relative to the quality control data. • Project Name: Iowa Site: Iowa Army Ammunition Plant S. F.

Project Name: City of Phoenix Site: City of Phoenix 19th Avenue Landfill S. F. Site Site ID: Type Lead: Requested by: Nadia Hollan (415) 744-2363 Lead Scientist: Mike Abbott (208) 526-8596 Start Date: May 2000 Expected Completion Date: November 2000 Revised Completion Date: March 2002 Estimated Budget: $ 18,000 Total Expenditures:$23,492 Revised Budget: $30,000 Total FY02 Expenditures:$950 Major Contaminants: Organics Total 1st Qtr. Expenditures:$950 The RPM requested that the ESD-LV TSC provide assistance in reviewing ambient air monitoring and monitoring plans. This 213-acre site operated as a landfill between 1957 and 1979, during which about 9 million cubic yards of municipal refuse, solid and liquid industrial wastes, and some medical wastes were deposited. However, the site was closed in 1979 due to the threat of flooding from the Salt River Channel. This remedial action is designed to mitigate threats resulting from flooding. The primary contaminants of concern in the soil/refuse include VOCs such as toluene and xylenes. The TSC received three documents for review: The Ambient Air Monitoring Plan and two Ambient Air Monitoring reports. Following the review it was felt that the four landfill air sampling tests were well conducted and that the results showed differential concentrations that were well below levels of concern. However, the number of samples (total of 8 events per cell) was not adequate to draw the conclusion that long- term VOC emissions from the landfill are of no concern. The sampling experimental design (discrete 4-hour upwind/downwind samples) has two inherent and compounding limitations that cannot be overcome with a limited number of samples: 1) the inability to distinguish source emissions from the relatively high background concentrations in the area and 2) the dilution of source emissions to below instrument detection limits because of air transport/dispersion to the downwind samplers. Some additional sampling was recommended. 38 ------- The TSC received a request from the RPM in early August for information on Open Path Fourier Transform Infrared Spectrometry (FTR), and whether it could be a useful tool at the landfill. The TSC responded on August 17 with some background information on the technology and some experience at the INEEL using this technology. The TSC believes that this technology would be a useful tool to address the landfill issues. The TSC received volumes 1 and 2 of the Ambient Air Monitoring Program Report and the Ambient Air Monitoring Plan for review. The review of these documents was completed and the report titled "INEEL Review Comments on the Ambient Air Monitoring Program Report for Nineteenth (19th) Avenue Landfill- Phase II."

Operable Unit Two is an area of contaminated groundwater down gradient of Operable Unit One. The selected remedy is an interim remedy designed to address groundwater that is contaminated with volatile organic compounds (VOCs). The major components of this remedy consist of extraction of groundwater in the vicinity of Interstate 10 and Van Buren Street, treatment of extracted water near extraction locations by either air stripping with off-gas treatment by synthetic resin adsorption, or advanced oxidation based on final design considerations, and injection of treated water back into the aquifer in locations allowing additional control of the contaminant plume. The TSC reviewed a number of site documents and provided comments. The existing data presented in site reports were of high quality but several significant data gaps were identified. Recommendations were made for installation of at least two new groundwater monitoring wells with soil gas ports. A peer reviewed paper Design, Installation, and Uses of Combination Ground Water and Gas Sampling Wells (Hubble, Wood, and Higgs, 1998) published by INEEL scientists was provided as a recommendation to assist in collection of soil gas data with installation of new groundwater wells. The TSC provided review comments on The Soil Vapor Extraction System Evaluation Report. The Environmental Restoration Directorate Sample Management Office reviewed the L&V reports supplied as Appendix B-H. While some discrepancies were noted in laboratory technique, the data were validated for use in evaluating the effectiveness of the Soil Vapor Extraction System (SVE). An independent technical memorandum produced by Golder Associates (GA) was also reviewed. The GA evaluation methodology was appropriate and the conclusion that the SVE system achieved the goals of the project was confirmed. It was 44 ------- noted however that the confirmation sampling was conducted just a few days after shutdown of the extraction system which did not allow sufficient time for contaminant concentration rebound. The recommendation was to conduct additional sampling to confirm the initial results. The TSC provided the Region with comments and recommendations pertaining to the 53rd Street soil gas data analysis. The TSC received a CD Rom of scanned site documents related to soil investigations and hard copies of related items. The purpose of the document review is to provide assistance in determining the sufficiency of site characterization at the site and beyond the CY and SWPL areas, and whether it is likely that further soils or groundwater cleanup will be necessary. The TSC is currently reviewing the site documents and will identify gaps as they are encountered. The TSC received the document titled "Characterization of Inorganic Constituents in Groundwater, 53rd Street Superfund Site for Motorola, Inc." dated July 1999 for review. Two modeling reports were received. The first report entitled "Preliminary Review of Groundwater Flow Models at the Motorola 53rd Street Superfund Site" and the second report titled "Summary of Preliminary Groundwater Flow and Contaminant Transport Simulations." Those reports were both prepared by the Hydrodynamic Group (HG) and present reviews of previous modeling efforts plus a description of a new model that HG prepared to help answer some questions on the potential effectiveness of a proposed pump and treat remedy. There were some valuable discussions, recommendations, and insights in the reports, but there were also some shortcomings and issues that need to be resolved. The TSC briefly outlines an approach for correcting major deficiencies and resolving problems. Ron Arnett provided written review comments in a report entitled "Review of Two Groundwater Flow and Contaminant Transport Model Reports for Motorola 53rd Street Superfund Site, Phoenix, Arizona," which was transmitted to Nadia Hollan. The TSC received six additional documents for review. A review of these documents was completed. The TSC also participated in a conference call with the RPM and the Arizona State Attorney Generals Office. The TSC reviewed ADEQ calculations pertaining to soil vapor extraction mass removal analysis and provided some recalculations. The TSC also provided the following documents to the RPM: "Review of Summary of Preliminary Groundwater Flow and Contaminant Transport Simulations Reports for OU-2 System Phoenix, AZ. Draft Version 2.0," dated August 2000 and "Review of Revised Groundwater Modeling Report on the Motorola/Honeywell OU-2 System Superfund Site" dated August 2000. The TSC also participated in a number of conference calls and meetings in San Francisco and Phoenix, AZ. TSC representatives attended a Honeywell site review 20-24 October. The review included an on-site tour of the Honeywell facility with a focus on the highest probability source area (LACC, oil chip yards, engine test cells, and return well.) An additional day included consultation on review of the Honeywell Conceptual Site Model and a meeting with the technical consultants for Honeywell. On November 6, 2000 the technical consultants presented their interpretation of the geology and hydrology and the flow and transport model supporting Motorola's interpretation of historical plume development. Meetings with both parties have demonstrated that significant effort has been expended on collection and interpretation of site-specific data, and progress is being made on development of a site conceptual model. The TSC participated in an on-site technical working group. The report titled "Review of Potential Source Areas Investigation Work Plan Honeywell International, Inc. 3Ist Street Facility" was provided to the Region. A number of site documents were received (i.e., Draft Five Year Review) by the TSC and were reviewed. A report identifying additional site characterization investigations at the Honeywell Street facility was received. • Project Name: Pemaco Site: Pemaco Maywood S. F.

Pemaco Maywood is a four-acre facility located in Maywood, California that housed a chemical blending facility operated by Pemaco, Inc. Between the 1940's and 1991 hazardous chemicals that were stored at the facility in underground and aboveground storage tanks and drums included chlorinated and aromatic solvents, flammable liquids, petroleum hydrocarbons, and other volatile organic compounds. There were 31 underground storage tanks, six aboveground storage tanks, and more than 400 drums on site when the facility was investigated by the Los Angeles County Fire Department hi 1992. During the Expanded Site Inspection (ESI) conducted in May 1997, several volatile organic compounds were identified in near-surface and deep soil samples, as well as perched ground water and an underlying regional aquifer. Floating product consisting of total petroleum hydrocarbons (gasoline) and 12 volatile organic compounds was recovered from three wells drawing from the perched ground water. Aqueous samples from 10 other wells in the perched ground water sone contained several chlorinated hydrocarbons such as tetrachloroethane. (PCE), trichloroethene (TCE), 1,1,1-trichloroethane (TCA), 1,1,-and 1,2-dichloroethene, 1,1- dichloroethane, and vinyl chloride. The TSC reviewed the QAPjP and the SOPs and provided the Region with the report titled "Review of the A4 Scientific, Inc.

Expenditures: $ 100 The Regional RPM requested that the ESD-LV TSC provide assistance in reviewing SOP's that are going to be utilized by an analytical laboratory for analyzing site samples. The San Fernando Valley site is an area of contaminated groundwater covering approximately 9,336 acres in the vicinity of the North Hollywood section of the City of Los Angeles. This area is part of the San Fernando Valley basin, a natural underground reservoir. Groundwater contaminated with volatile organic compounds (VOC's) was discovered in 1980. Some groundwater contaminants currently affecting the Basin's water supply can be traced back to a period between 1940 and the 1960's, when the disposal of large chemical wastes was unregulated throughout the valley. Following a review of the available SOP's the TSC provided the Region with a report titled "Review of the EMAX Laboratory Quality Assurance Manual and Standard Operating Procedures Prepared for the EPA Region 9 Regional Environmental Analytical Procurement Contract." Additional support is anticipated. • Project Name: Sierra Site: Sierra Army Depot S. F.

Expenditures:$615 47 ------- The Project Officer requested that the ESD-TSC provide assistance by participating in a work group which will assess the feasibility of conducting air plume testing for open burn/open detection (OB/OD) operations. The Sierra Army Depot located near Herlong, CA is a government owned and operated installation under the jurisdiction of the U. S. Army Operations Support Command (OSC), Rock Island, Illinois. The depot conducts business 10 hours a day, Monday through Thursday, although mission operations are usually underway five or six days a week. CRREL personnel (USAGE) were contacted concerning OB/OD. They indicated that 2, 4-dinitrotoulene, RDX, and nitroglycerine were the three compounds of concern. The TSC is currently waiting for information pertaining to work group meeting times and places. Project Name: Valeteria Site:Valeteria Dry Cleaning S. F. Site Site ID: Type Lead: Requested by: Dan Shane (415) 972-3037 Lead Scientist: Clark Scott (208) 526-2919 Start Date: July 2001 Expected Completion Date: December 2001 Revised Completion Date: January 2002 Estimated Budget:$15,0000 Total Expenditures:$4,870 Revised Budget: $ Total FY02 Expenditures:$500 Major Contaminants: Organics/Inorganics Total 1st Qtr. Expenditures:$500 The Regional RPM requested that the ESD-LV TSC provide assistance in providing ground penetrating radar (GPR) (Geophysics) support. The purpose of GPR support work would be to identify the location of a septic system at the site so a few soil borings could be collected. Currently, the location of septic system is not known. The results of previous sampling events at the Valeteria Dry Cleaners site indicate that VOCs have been detected in the shallow groundwater, surface water, soils, and a spring in the vicinity of the site. The most significant concentrations of VOCs present are those of PCE, which was detected in the shallow groundwater beneath the site. Sampling data suggest that PCE has been transported to groundwater from an abandoned septic tank to a spring outfall along the San Lorenzo River. The old septic leach field area is also a potential source for PCE in groundwater. The geophysical survey was conducted on July 2lst. There were approximately 30 profiles taken over the site with the majority being on a grid in the area of the suspected leach field. The results of the survey showed the septic tank to be located toward the deep end of an asymmetric excavation between the two main buildings, There were no clear indications of piping leading from the tank, but a disturbed zone interpreted to be associated with the leach field was delineated. This leach field is in front of the eastern half of the building (currently a thrift store) directly to the west of the septic tank. Interpretations were made and discussed at the field site with further sampling planned based on those results. Project Name: Williams Site: Williams AFB S. F. Site Site ID: 48 ------- Type Lead: Requested by: Steve Remaley (415) 972-3802 Lead Scientist: John Zimmerman (702) 897-3279 Start Date: October 2001 Expected Completion Date: April 2002 Revised Completion Date: Estimated Budget: $20,000 Total Expenditures:$434 Revised Budget:$ Total FY02 Expenditures:$434 Major Contaminants: Organics Total 1st Qtr. Expenditures:$434 The Regional RPM requested that the ESD-LV TSC provide assistance in reviewing laboratory data, QA documents and perform a data audit on GC/MS data. The 4,127-acre Williams Air Force Base (WAFB) site, located in Chandler, Arizona, was commissioned as a flight training school in 1941. Contaminants from base activities include organic solvents and paint strippers, petroleum spills, metal plating wastes, hydraulic fluids, pesticides, and radiological waste. Discharges and disposal at WAFB have resulted in soil and groundwater contamination. Ten sites have been identified as contaminated areas including two fire training areas, a fuel storage area, two surface storm drainage areas, a hazardous material storage area, a landfill, a pesticide burial pit, a radiological disposal area, and several underground storage tanks. Following an assessment of provided laboratory data the TSC provided the Region with the report titled "Audit Report of Hard Copy and Electronic Data from Columbia Analytical Services, Inc. Redding, California for the Williams A.F.B. Superfund Site." • Project Name: Yuma Site: Yuma (MCASY) S. F.

Site Site ID: Type Lead: Requested by: Cami Grandinetti (206) 553-8696 Lead Scientist: Bob Starr (208) 526-5687, ErickNeher (208) 526-5449, Mike Roddy (208) 526-8201 Start Date: July 2000 Expected Completion Date: March 2001 Revised Completion Date: August 2002 Estimated Budget: $30,000 Total Expenditures:$42,912 Revised Budget: $80,000 Total FY02 Expenditures:$900 Major Contaminants: Inorganics Total 1st Qtr. Expenditures:$900 The Region X RPM has requested the ESD-LV TSC to provide assistance in the identification of innovative approaches for conducting vadose zone characterization, emerging fracture filling or compensation grouting technologies, and manipulating the geochemical environment to precipitate toxic metals. The Bunker Hill Mining District is located within the Coeur d'Alene River Basin in the eastern portion of the panhandle of northern Idaho. Historic ore mining, milling, and smelting practices have resulted in widespread mining-related contamination of the basin. In 1992, a ROD was signed for the non-populated areas of the Bunker Hill Superfund Site (BHSS), and implementation began in 1995. In 1998, EPA initiated an RI/FS of mining-related contamination in the Coeur d'Alene River Basin. The TSC participated in a on-site visit. The purposes of the visit were to: 1) meet with Idaho State DEQ and Silver Valley Trustees regarding provision of technical assistance for the Success Mine pilot in which the TSC would develop a protocol for predicting the adsorptive capacity of materials useful in the passive treatment of 50 ------- Acid Mine Drainage (AMD); and (2) meet with EPA officials regarding request for technical assistance in solving problems associated with characterization of the Bunker Hill CERCLA site. A Scope of Work (SOW) was prepared and sent to the Region during November 2000. The SOW details the tasks for evaluating the feasibility of determining recharge areas that are contributing to the metals load in the mine drainage at the Bunker Hill mine. Following a review of appropriate geologic and hydrogeologic information the determination that a tracer test would yield the desired information was made. These suggestions and recommendations were provided to the Region in the report titled "Review of Bunker Hill Mine Hydrogeologic Data and Tracer Test Evaluation" dated May 7, 2001. Based on the hydrology of the site and significance of snow melt infiltration, it is likely that the tracer studies will have to be delayed until next spring. The reasons for the delay are low snowfall and a high probability that by the time a tracer test plan is completed, the spring runoff will be over. Project Name: Bonneville Site: Camp Bonneville S.

Exp:$200 PC&B:$0 The RPM requested that the ESD-LV TSC provide assistance in reviewing the Unexploded Ordnance (UXO) Statistical Sampling (SiteStats/Grid Stats) and Risk Assessment (OECert) Methodology. These programs were developed for conducting engineering evaluation/cost analysis (EE/CA), and UXO investigations for various ordnance and explosives (OE) located on Formerly Used Defense Sites (FUDS). Three statisticians, Dr's Max Englehardt, Ashok K. Singh, and Anita Singh, were asked by the TSC to review and assess provided documents and computer programs. Camp Bonneville is a 3,839-acre site located in southwestern Washington State that has been utilized by the Department of the Army and others for training exercises for approximately 85 years. Large residential developments, densely forested lands, and small farms bound the property on all sides. Two areas within Camp Bonneville, totaling 820 acres, are currently leased from the Washington Department of Natural Resources. The Department of the Army used Camp Bonneville for live fire of small arms, assault weapons, artillery, and field and air defense artillery between 1910 and 1995. Since 1947, Camp Bonneville has also provided training for a variety of military and non-military units from the National Guard, Reserves, and U.S. Air Force to federal, state, and local law enforcement agencies. In July of 1995, Camp Bonneville was selected for closure under the 1995 Base Realignment and closure (BRAC) process. The TSC reviewed provided site documents and data. Following this review a data base was developed. A number of simulations for assessing USAGE models (i.e., UXO calculator) were completed. The report titled 51 ------- "Interim Evaluation of U. S. Army Corps of Engineers Statistical UXO Sampling and Characterization Methodologies" was completed and sent to the Region and the OSWER Program Office. The draft report titled "Evaluation of U. S. Army Corps of Engineers Statistical UXO Sampling and Characterization Methodologies" dated July 2000 was prepared and distributed for comments. TSC "personnel" met with the USAGE in Las Vegas for discussions pertaining to the USAGE developed UXO programs. The TSC participated at a SERDP presentation and meeting pertaining to improving UXO Characterization approaches. The TSC also completed a number of statistical tests pertaining to characterizing UXO.

Singh (702) 895-1439 Start Date: January 2001 Expected Completion Date: September 2001 Revised Completion Date: February 2002 Estimated Budget: $6,000 Total Exps:$2,699 PC&B:$1,000 Revised Budget: $ Total FY02 Exp:$300 PC&B:$0 Major Contaminants: Total 1st Qtr. $300 PC&B:$0 The Region VII Toxicologist requested that the ESD-LV provide assistance in investigating the exposure of children living in methamphetamine clandestine homes being used to manufacture methamphetamine. The Anti-Abuse Act of 1988 established a Joint Federal Task Force on illegal drug laboratories. The Task Force consisted of representatives of the U. S. DEA and the USEPA and representatives of the USCG. Congress directed the Task Force to formulate a program for cleaning up and disposing of hazardous wastes produced by clandestine drug laboratories. The TSC met with the Toxicologist and discussed a number of exposure model(s) and data requirements necessary for running the model(s). The TSC will participate in model assessment(s) and conducting Monte Carlo data simulations. The TSC participated in a number of calls and discussions pertaining to data assessment simulations and modeling efforts. The TSC received the document titled "Lognormal Distribution for Body Weight as a Function of Age for Males and Females in the United States" for review. TSC reviewed the "Lognormal" document and had a number of discussions and e-mail communications with the Region. Project Name: UST Vapor Monitoring Site: UST Vapor Monitoring Guidance Document Site ID: Type Lead: Requested by: Jack Hwang (215) 814-3386 Lead Scientist: A. K. Singh (702) 895-0364 Start Date: Expected Completion Date: August 2001 57 ------- Revised Completion Date: April 2002 Estimated Budget:$6,000 Revised Budget:$ Major Contaminants: Organics Total Expenditures:$2,400 Total FY02 Expenditures:$1,400 Total IstQtr. Expenditures:$1,400 The Regional Project Officer requested that the ESD-LV TSC provide assistance in reviewing and evaluating the data assessment and statistical methods/procedures that are being utilized in the UST guidance document Regional inspectors evaluated vapor concentration data from vapor monitoring wells and brought up the issue of how should environmental scientists determine what constitutes a "significant" increase in vapor concentration at a site. UST Technical Regulations require persons using vapor monitoring will be effective for the site. Vapor monitors must be able to detect any significant increase in concentrations above the background of the regulated substance stored in the tank system. If no releases occur during the first year of system operation, the tank/owner/operator may re-calculate the background concentration for each well by using the original background data and the monthly monitoring data from the previous year. The UST guidance document provides and suggests procedures that can be used to assess background/monitoring well data. Following a review of the "document" the TSC provided the Region comments and suggestions in the report titled "Review of Recommendations for Establishing Background Consent." The TSC received contaminant data from wells 3, 6, 7A and 11 for calculating the 95% UCL. The TSC is in the process of completing this statistical data assessment. Project Name: UVA Hillside Site: UVA Hillside Disposal Area Site ID: Type Lead: Requested by: Russell Fish (215) 814-3226 Lead Scientist: Wayne Sovocool (702) 798-2212 John Zimmerman (702) 897-3279 Start Date: September 2001 Expected Completion Date: March 2002 Revised Completion Date: Estimated Budget:$5,000 Revised Budget:$ Major Contaminants: Organics Total Expenditures:$404 Total FY02 Expenditures:$404 Total 1st Qtr. Expenditures:$404 The Regional Project Officer requested that the ESD-LV TSC provide assistance in determining the cause of anomalous bis (2-Ethylhexyl) phthalate concentration in groSndwater samples from the Hillside Disposal area. In 1981, the Virginia Department of Health designated a former debris disposal area at the University of Virginia (UVA) as a rubble/debris landfill. The University performed a preliminary evaluation of the facility during the summer of 1999. This evaluation indicated slightly elevated levels of certain contaminants at the Site. Based on this information and historical disposal practices, the USEPA requested that UVA investigate possible contamination. 58 ------- Elevated levels of bis (2-Ethylhexyl) phthalate have bound found in all three groundwater sampling events, and there is no consistent pattern to indicate a ground water plume and/or a discernible source. A brief literature search indicates that bis (2-Ethylhexyl) phthalate is a manufactured chemical that makes plastic more flexible. The Region is also a common sampling and or laboratory artifact. Following a review of site data the TSC provided the following information to the Region. "This common plasticizer compound has been produced in enormous quantities and degrades slowly, has some water solubility and some vapor pressure and has become truly ubiquitous, especially due to the world-wide use of plastics. That means that finding it in environmental samples is not at all unusual, however, proving its origin can be difficult. This comes about because it is present also in the very organic solvents that are used to extract the environmental samples, Also, if any plastic material comes in contact with the samples, or the solvents, or the apparatus used to extract the samples, this is capable of contaminating the samples with this phthalate and also other phthalates (as butyl phthalates) and other plasticizers." 59 ------- SUPERFUND COORDINATION Project Name: Superfund Coordination Site: Superfund Coordination Site ID: Type-Lead: Requested by: Ken Brown Lead Scientist: Tim Ehli (702) 897-3264, Ken Moor (208) 526-8810 Start Date: October 2001 Expected Completion Date: September 2002 Revised Completion Date: Estimated Budget: $25,000 Total Expenditures:$2,697 Revised Budget: $ Total FY02 Expenditures:$2,697 Major Contaminants: N/A Total 1 st Qtr.

Expenditures:$ 1,180 One of the objectives of the TSC is to identify and make available BSD 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. All ESD fact sheets have been updated. The Superfund Program Office requested that the ESD-LV TSC provide information and documentation pertaining to the operation and utilization of a vacuum distillation/gas chromatography/mass spectrometry instrument. The purpose of this effort is to adequately describe this instrument and provide written guidance that will enable Regional chemists to measure hazardous waste contaminants. The following information shall be addressed in this SOP. General introduction: including brief overviews of the concepts of and needs for vacuum extraction, gas chromatography, and mass spectrometry. Instrumentation: including sources of all instrument parts, suggestions about equipment parts (if appropriate), reagent sources (including gases), and glassware.
