INAAP suspected propellant burial area east of P loop site 24 report Apr 2003

Description:	The revised final report for the suspected propellant burial area east of P loop site 24 at Indiana Army Ammunition Plant of Phase II RCRA facility investigation prepared for U.S. Army Corps of Engineers in April 2003.The United States federal government began acquiring land in Charlestown, Indiana in 1940 to build a smokeless powder ordnance plant to supply the US military during World War II. Indiana Ordnance Works (IOW) Plant 1 and Hoosier Ordnance Plant (HOP) began production in 1941. In 1944, IOW Plant 2 construction began. On 30 Nov 1945 at the end of WWII, the three plants were combined and renamed Indiana Arsenal. Between 1 Nov 1961 and 1 Aug 1963, the plant was designated Indiana Ordnance Plant. After this time, it became Indiana Army Ammunition Plant (INAAP). Production of ordnance continued at the plant until 1992. After that time, the land and facilities were leased to private industry. A large portion of the land became Charlestown State Park. In October 2016, all the land and facilities were officially sold by the government. This item is part of a larger collection of items from INAAP that are kept at Charlestown Library.

The report also summarizes the results of the previously completedPhase I Remedial Investigation (RI).INAAP currently encompasses approximately 9,790 acres in south-central Clark County,Indiana. Its southern boundary is approximately 6 miles north of Jeffersonville, Indiana and 10miles from the Louisville, Kentucky metropolitan area, which lies to the south across the OhioRiver. INAAP is a Government-Owned, Contractor-Operated, inactive military industrialinstallation. The Army intends to transfer the property to the Local Reuse Authority forcommercial development or to the State of Indiana for inclusion in the state park system. TheAniline Pond is one of 90 sites identified at INAAP.The Plant was originally constructed as three separate facilities: The Indiana Ordnance WorksPlant 1, the Hoosier Ordnance Plant, and the Indiana Works Plant 2. The three facilities wereconsolidated into the Indiana Arsenal in 1945. The Indiana Arsenal was redesignated as theIndiana Ordnance Plant in 1961; in August 1963, it was redesignated again as the Indiana ArmyAmmunition Plant.Topography at the INAAP can be described as a middle-aged karst topography. Karsttopography is produced by the dissolution of limestone, gypsum, or other readily soluble rocks,commonly along joints, fractures, bedding planes, or other such features. The dissolutionprocess results in the formation of sinkholes, caves, and underground drainage. Numeroussinkholes and springs are found throughout much of INAAP.Approximately 96 percent of INAAP’s land surface drains directly into the Ohio River via sevendrainage basins. The remaining 4 percent reaching the Ohio River indirectly through thePheasant Run basin.Groundwater at INAAP is present in the bedrock formations of the upland areas and in theterrace/floodplain sand and gravel deposits located within the Ohio River valley. Thegroundwater present in the floodplain aquifer along the Ohio River is a major water supplysource. Groundwater is not usually found in the thin soil layer covering the bedrock surface inthe upland areas. When present, shallow groundwater typically mingles with surface water byflowing in and out of karst features.The Phase I and II investigations at the Suspected Propellant Burial Area East of ‘P’ Loop (Site24) included the completion of an electromagnetic (EM) survey, a seismic refraction survey, fourtrenches, and nineteen soil borings, and the collection and analysis of 13 surface soil and 23subsurface soil samples, two sediment samples and one groundwater sample. Chemical analysisincluded Volatile Organic Compounds (VOCs), Semi-volatile Organic Compounds (SVOCs),pesticides, polychlorinated biphenyls (PCBs), nitroaromatics/nitramines, and metals analysis.The Suspected Propellant Burial Area East of ‘P’ Loop (Site 24) is located in the east-central partof INAAP on the eastern edge of the Rail Shiphouse Area (Site 65). The site covers about oneacre and consists of waste materials that have been dumped in a low area cleared of trees. BasedSuspected Propellant Burial AreaExecutive Summary East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA ES-2on interviews, aerial photographs, records review, and site reconnaissance, Site 24 wasreportedly used as a propellant burial area and construction debris landfill (ENSR 1992; ASI1994). During site reconnaissance and field activities of the Phase I RI and Phase II RFI,construction debris was observed on the ground along the western, eastern and northern portionsof the burial area. The site is currently a southward sloping plateau overgrown with grass, weedsand small shrubs, and is surrounded by dense woodlands in all directions. The ground surfacehas a radial slope in all directions from the cleared burial area, and the southern edge of theburial area is about 10 to 15 feet above the natural ground surface.Local surficial geology at the Suspected Propellant Burial Area East of ‘P’ Loop (Site 24), basedin part on an electromagnetic (EM) survey, seismic refraction survey, and trenching activitiescompleted as a part of the Phase I RI, indicate bedrock at the burial area is overlain by about 1 to16 feet of fill soil, construction debris, and residual soil. There was no propellant observed onthe ground surface of the site, or within soil borings and trenches. Construction debris wasobserved in the borings and trenches from the ground surface to depths of up to 8 feet belowground surface (bgs). The buried construction debris typically consists of silty clay with asphalt,gravel, concrete, brick, and wood ties and is underlain by soil fill, residual soils or limestonebedrock. Residual soils ranged from 3 to approximately 8 feet thick. The residual soil typicallyconsists of low to medium plastic, silty clay and is underlain by limestone bedrock. Depth tobedrock ranged from less than 2 feet to slightly more than 15 feet. Groundwater wasencountered at six borings and two trenches at depths ranging from 1.0 to 12.3 feet bgs.A contamination assessment was completed for near surface soil and sediment, subsurface soiland groundwater. Low levels of VOCs, SVOCs and pesticides were detected throughout the sitein the shallow soil to intermediate subsurface soil depths. Elevated levels of two SVOCcompounds were detected in the near surface soil and in the intermediate subsurface soil depthstoward the center of the site. PCBs were detected in the northern and central portions of the sitein shallow soils and several metals results exceeded background concentrations for all mediasampled at the site.A human health risk evaluation was performed on all contaminants found in surfacesoils/sediments, total soils/sediments, and in groundwater at the Suspected Propellant BurialArea East of ‘P’ Loop (Site 24). The cancer risks ranged from 9 x10-10 to 4 x 10-8 for theRecommended Maximum Exposure (RME) and 3 x 10-10 to 2 x 10-9 for Central TendencyExposure (CTE). Hazard indices ranged from .000008 to .02 for RME and .00000006 to .00007for CTE. The results indicate that the potential primary carcinogenic risk driver is incidentalingestion of 2,4-dinitrotoluene (2,4-DNT) from soil. The potential primary non-carcinogenicrisk driver is ingestion of 2,4-DNT and aluminum in soil.An ecological risk screen was performed on all contaminants found in surface soils andsediments at the Suspected Propellant Burial Area East of ‘P’ Loop (Site 24). Whenconcentrations exceeded risk screen values, the analyte was considered a Contaminant ofPotential Ecological Concern (COPEC) and evaluated in an ecological risk assessment. Riskswere evaluated for key ecological processes, and for organisms found to be important andrelevant for a healthy self-sustainable ecosystem as well as area-specific concerns. Figure 9-1shows detects above ecological risk screening criteria.

Thesite is currently a southward sloping plateau overgrown with grass, weeds and small shrubs, andis surrounded by dense woodlands in all directions. The ground surface has a radial slope in alldirections from the cleared burial area, and the southern edge of the burial area is about 10 to 15feet above the natural ground surface. To the north, the ground surface slopes toward atopographic depression. To the east and south, the ground slopes to intermittent streams, and tothe west, the ground levels out to P Avenue. The streams to the south and east of the burial areameet south of the site and flow past the Ravine Dumping Ground (Site 59), to Jenny Lind Pond(Site 25), and ultimately discharge to the Ohio River.1.1 OPERATIONAL HISTORY AND WASTE CHARACTERISTICSBased on interviews, aerial photographs, records review, and site reconnaissance, the SuspectedPropellant Burial Area East of ‘P’ Loop (Site 24) was reportedly used as a propellant burial areaand construction debris landfill (ENSR 1992; ASI 1994).During site reconnaissance and field activities of the Phase I RI and Phase II RFI, constructiondebris was observed on the ground along the western, eastern and northern portions of the burialarea. The construction debris consisted of concrete, rebar, polyvinyl chloride (PVC) pipes,partially buried and rusted 55-gallon drums, asphalt, brick, electrical switch boxes, metal signs,railroad ties, scrap metal and glass. There was no propellant observed on the ground surfacewithin or around the site.Site Location and DescriptionSECTIONONE Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 1-21.2 PREVIOUS INVESTIGATIONSDames & Moore completed a Contamination Survey along the eastern edge of the site in 1984(D&M 1984). However, the analytical methods used are now obsolete, rendering the analyticaldata collected during this survey incomparable to the data collected, following current standards,during the Phase I RI and the Phase II RFI. Therefore, this data was not used.Woodward-Clyde (W-C) completed a Phase I RI at this site in 1995 (W-C 1998).For additional information regarding the previous investigations completed at INAAP, refer toSection 3 of the Sitewide Work Plan (URSGWC 2000a).1.3 REPORT ORGANIZATIONThis report compiles the Phase I RI report (W-C 1998) with the results of the Phase II RFI (URS2002).

The locations of the sampling points are provided on Figure 2-1. Sample location,identification, depth, matrix, and chemical analyses are presented in Table 2-1 for samplescollected in 1996, and in Table 2-2 for samples collected in 2002. All field activities werecompleted in accordance with applicable Standard Operating Procedures (SOPs) (W-C 1998,URSGWC 2000b, URS 2002). Any deviations from the SOPs are noted on the SampleCollection Field Sheets (SCFS), provided in Appendix G.2.1 TRENCHINGAs part of the Phase I RI field activities, four 20-foot long trenches were excavated to evaluatethe lateral and vertical extent of refuse, depth to bedrock, soil types, and thickness of the existingsoil cover. Trench locations are provided on Figure 2-1 and are summarized below:· 24T1 - through the construction debris observed on the ground surface in the easternportion of the burial area· 24T2 – adjacent to the construction debris observed on the ground surface along thesouthern edge of the burial area· 24T3 - in the central portion of the burial area adjacent to the construction debrisobserved on the ground surface· 24T4 - along the northern edge of the burial area adjacent to the construction debrisobserved on the ground surfaceThe trenches were excavated using a John Deere Model 310D backhoe operated by CETEnvironmental, under the supervision of W-C personnel. W-C personnel logged the trenches toindicate the depth and thickness of buried materials, soil types, and the depth to bedrock. Thetrenches were generally completed to 10 feet or bedrock, whichever was first encountered.Trenches 24T1 through 24T3 encountered bedrock in the 2- to 10-foot bgs interval. Trench24T4 was excavated to 10 feet bgs, and bedrock was not encountered. Each trench wasbackfilled with the excavated soils. Results of the trenching and test pit activities are reported inSection 3.2.2 GEOPHYSICAL SURVEYAn EM survey and seismic refraction survey were completed at the Suspected Propellant BurialArea East of ‘P’ Loop (Site 24) as part of the Phase I RI field activities. The purpose of the EMsurvey was to locate buried materials and the seismic refraction survey to map the depth tobedrock. The location and area of the surveys are shown in Figure 2-2. Results of the EMsurvey are reported in Section 3.Field Activities SummarySECTIONTWO Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 2-22.3 SOIL AND SEDIMENT SAMPLING2.3.1 SoilThirteen soil borings were advanced in areas of suspected contamination based on trenching (seeSection 2.1), geophysical survey data (see Section 2.2), historical information, and topography.During the Phase I RI, six soil borings (24SB01 through 24SB06) were drilled using hollow stemaugers (4 ¼-inch inner diameter, 8-inch outer diameter) and a 3-inch diameter stainless steel splitspoon. The maximum depths ranged from approximately 6 to 13 feet bgs. For the Phase II RFI,seven borings (24DS01 through 24DS07) were completed using a direct push system and 1.75-inch diameter polyvinyl chloride (PVC) liners. The maximum depths ranged fromapproximately 2 to 15 feet bgs. These boring were completed at the following locations (seeFigure 2-1):· 24SB01 – approximately 10’ south of 24T3 in the central portion of the burial area· 24SB02 – approximately 10’ north of 24T4 at the northern end of the burial area· 24SB03 – approximately 20’ west of 24T2 south of the burial area· 24SB04 – approximately 100’ west of 24T2 southwest of the burial area· 24SB05 – west edge of burial area between tree line and construction debris· 24SB06 – adjacent to 24T1 in construction debris at eastern end of burial area· 24DS01 – approximately 130’ north of 24T4 in tree line at north end of burial area· 24DS02 – approximately 60’ west of 24T4 at tree line on east side of burial area· 24DS03 – adjacent to 24T3 in construction debris in the middle of the burial area· 24DS04 – approximately 75’ southwest of 24T3 on southwest slope of burial area· 24DS05 – between construction debris and tree line at northwest edge of burial area· 24DS06 – approximately 40’ south of 24T4 in north central part of burial areaAdditionally, six surface soil samples were collected in areas of suspected contamination as partof the Phase I RI field activities. The surface soil samples were collected to maximumapproximate depths of 2 feet bgs. The surface soil samples were collected at the followinglocations (see Figure 2-1) using a stainless-steel hand auger:· 24SS01 – adjacent to the construction debris approximately 80’ north of 24T1· 24SS02 – eastern end of burial area approximately 30’ southeast of 24T1· 24SS03 – approximately 60’ southwest of 24SS02, southeast of burial area· 24SS04 – approximately 40’ southwest of 24T2, south of burial area· 24SS05 – south of burial area approximately 100’ west of 24T2· 24SS06 – southwestern corner of burial area next to tree lineField Activities SummarySECTIONTWO Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 2-3Typically, three samples were retained for chemical analysis from each soil boring, and onesample was retained for chemical analysis from each surface soil sampling location. However,due to their relatively shallow total depths, only two samples were collected from borings24DS01 and 24DS07, and one sample was collected from 24DS05. Additionally, due to arelatively deeper depth for boring 24DS06, four samples were collected. Sample identification,depth, matrix, and chemical analysis are presented in Tables 2-1 and 2-2. Boring locations areshown in Figure 2-1.2.3.2 SedimentTwo sediment samples were collected from surface drainage features along the eastern andsouthern boundaries of the burial area as a part of the Phase II RFI field activities. Surface waterwas not present in the drainages at the time of sediment sample collection. The sedimentsamples were collected from the following locations (see Figure 2-1):· 24SD01 – approximately 120’ south of the standing water north of the burial area· 24SD02 – in drainage bordering south central side of burial areaSediment samples were collected from 0 to 0.5 feet bgs using a hand trowel. Sampleidentification, depth, matrix, and chemical analysis are presented in Tables 2-1 and 2-2. Samplelocations are shown in Figure 2-1.2.4 GROUNDWATER SAMPLINGOne groundwater sample was collected from the direct push boring 24DS06 during the Phase IIRFI field activities. It was not possible to collect a sufficient quantity of groundwater from theboring during the initial sampling interval; therefore, in order to obtain a sufficient quantity,groundwater samples for SVOCs, nitroaromatics/nitramines, and metals were collected from thislocation during three intervals over a 5-hour period. Afterwards, the boring remained dry andpesticide and PCB samples were not collected.A Geoprobe® pre-packed monitoring well screen was used during the collection of groundwatersamples from the Site 24 boring. Prior to the collection of the groundwater samples,approximately 1.25 liters (L) of water were purged from the boring using a peristaltic pump andhigh density polyethylene (HDPE) tubing. Samples for chemical analysis were also collectedusing the peristaltic pump and HDPE tubing.Sample identification, depth, matrix, and chemical analysis are presented in Tables 2-1 and 2-2.Boring locations are shown in Figure 2-1.2.5 FIELD SCREENING RESULTSField screening was completed during the Phase I RI and Phase II RFI field investigations usingheadspace analysis as described in SOP No. 15 of the Sitewide Work Plan (URSGWC 2000a).Field Activities SummarySECTIONTWO Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 2-4Recovered soil from each boring and sediment sample was field screened using aphotoionization detector (PID) to verify the presence or absence of organic vapors.

The site is situated in an Upland area characterized by karst topography associatedwith shallow limestone bedrock.The surface of the site is relatively even with a few dips and rises in the surface, and slopesgenerally to the south. Along the edges of the burial area, the ground surface slopes away fromthe site. To the north, the ground surface slopes toward a topographical depression. To the westthe ground levels out to P Avenue. To the south and east the ground slopes to intermittentstreams. These streams meet south of the site and flow past the Ravine Dumping Ground (Site59), to Jenny Lind Pond (Site 25). The pond discharges to the Ohio River. Relief varies from afew feet on the northwest corner to 10 to 15 feet on the southern and eastern sides of the site.A depression about 50 feet long by 20 feet wide by 2 feet deep exists to the north of the site (seeFigure 1-2). Standing water was observed in the depression during the Phase I RI and Phase IIRFI field activities. The depression does not appear to be a sinkhole. The side slopes of thedepression consist of clay soil. Debris was not observed in the vicinity of the depression.Access to the Suspected Propellant Burial Area East of ‘P’ Loop (Site 24) is by a gravel accessroad from P Avenue, which is overgrown with grass and weeds.3.2 LOCAL SURFICIAL GEOLOGYThe local surficial geology of this site has been interpreted based on electromagnetic and seismicrefraction surveys, four observation trenches, 13 soil borings, six surface soil samples and twosediment samples. Results of the electromagnetic survey are shown on Figures 3-1 through 3-4.Seismic refraction survey results are shown on Figures 3-5 and 3-6. The surficial geology ispresented in 2 geologic cross-sections. The locations of the cross-sections are shown on Figure3-7, and the cross-sections are shown on Figures 3-8 and 3-9.3.2.1 Geophysical Survey ResultsThe geophysical investigation consisted of an EM survey to locate buried materials and a seismicrefraction survey to map the depth to bedrock.EM SurveyThe EM survey was done on September 11, 1995. Prior to completing the survey, a geophysicalsurvey grid system was established using optical survey techniques and taped distancemeasurements. EM data were collected using the Geonics EM-31. Surveying of theapproximately 1.5-acre site was conducted using a uniform data spacing of 10 feet. EM datawere collected using the vertical and horizontal dipole modes. Quadrature phase and inphasedata were collected at each station in both dipole modes. The approximate area of the EMsurvey is shown on Figure 2-2.Physical Investigation ResultsSECTIONTHREE Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 3-2The EM survey indicated the site contained very little buried metallic debris. The inphasemeasurements (Figures 3-2 and 3-4) and the negative results (blue responses) shown on thequadrature response maps (Figures 3-1 and 3-3) indicated the presence of some metallic objects.Most of these responses were the result of metal construction debris observed on or protrudingfrom the ground surface, including rebar, parts of corrugated metal panels, and some 55-gallondrums with roofing tar residue. Due to the general lack of anomalies indicated by the EMsurvey, borings and trenches were not targeted at specific anomalies.Seismic Refraction SurveyThe seismic refraction survey was done on October 1, 1995. Two seismic refraction spreadswere done nominally perpendicular to each other (see Figure 2-2). A total of 460 linear feet ofseismic refraction data were collected. A geophone spacing of 10 feet was used, which resultedin a spread length of 230 feet. Both seismic spreads had three seismic source locations, one oneach spread end and one in the middle. Relative elevations of each geophone location wereobtained in the field using a hand level. The seismic energy source used for the refraction surveywas a sledgehammer.Figure 3-5 shows the results for the east-west seismic refraction transect (line 2401 on Figure 2-2) while Figure 3-6 shows the results for the north-south seismic refraction transect (line 2402 onFigure 2-2). No borings or trenches were completed along the east-west transect. Severalborings and trenches were completed along or near the north-south transect, including (fromnorth to south on Figure 2-1) 24SB02, 24T4, 24SB06, 24DS03, 24T3, and 24SB01. The depth tobedrock at each location is identified in the following table:Boring orTrench No.Depth to Bedrock Indicated bySeismic RefractionDepth to Bedrock Indicated byBoring or Trench24SB02 13 6.124T4 14 NA24SB06 13.5 12.524DS03 12.5 10.724T3 11 924SB01 9 8Trench T4 was only excavated to 10 feet below ground surface.Figures 3-5 and 3-6 indicate the bedrock surface is highly variable. The depths indicated by theseismic refraction are generally within 2 feet of depths indicated by the borings and trenches;however, estimating the boring and trench locations on the seismic refraction cross-sectionslikely introduced some margin of error into comparing the depth of bedrock from the seismicrefraction results to the borings and trenches.Physical Investigation ResultsSECTIONTHREE Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 3-33.2.2 Soil Borings, Trenches and Geotechnical ResultsThe seismic refraction survey, trenching and boring activities indicate bedrock at the burial areais overlain by about 1 to 16 feet of fill soil, construction debris, and residual soil.The borings and trenches encountered fill soil from 0 to 13.2 feet, which was generally observedabove and below buried construction debris. The fill soil exists from the ground surface tobedrock at Borings 24SB02, 24SB04, and 24SB05. Residual soils ranged from 3 toapproximately 8 feet thick. Depth to bedrock ranged from less than 2 feet to slightly more than15 feet.The EM survey results and trenching and boring activities indicated construction debris exists onand below the ground surface over the majority of the burial area. Construction debris wasobserved in the borings and trenches from the ground surface to depths of up to 8 feet bgs (seeFigures 3-8 and 3-9). The buried construction debris typically consists of silty clay with asphalt,gravel, concrete, brick, and wood ties and is underlain by soil fill, residual soils or limestonebedrock. There was no propellant observed on the surface of the site, or in soil borings, trenchlocations, and surface soil and sediment sample locations.Residual soil was observed below the fill and construction debris material at trenches 24T3 and24T4 and at soil borings 24SB03, 24DS03, and 24DS06. The residual soil typically consists oflow to medium plastic, silty clay and is underlain by limestone bedrock. Results from the soilborings, trenches and geotechnical data suggest the bedrock surface slopes to the south andsoutheast.In summary, the subsurface materials encountered were typically described as:· Fill - Stiff to very stiff, moist to wet, low to high plastic, silty clay (USCS SymbolCL-CH), with occasional pieces of shale· Construction debris - Low plastic silty clay (CL) with sand and asphalt, gravel,concrete, brick and/or wood ties· Residuum - Stiff, moist, low to medium plastic, silty clay (USCS Symbol CL)3.3 SHALLOW HYDROGEOLOGYGroundwater was encountered at the time of shallow soil sampling, drilling subsurface borings,and trenching activities.

Reporting limits were elevated due to soil moisture content, whichranged from 8 percent to 58 percent. See the Phase I RI report (W-C 1998) for a more detaileddiscussion of data review issues.4.2 PHASE II RFIAll chemical data were reviewed following procedures identified in the INAPP Site WideQuality Assurance Project Plan (QAPP) (URSGWC 2000). Analytical data for several samplescollected at the Suspected Propellant Burial Area East of ‘P’ Loop (Site 24) were qualifiedestimated (J/UJ) for select compounds based on surrogate, LCS, MS/MSD, lab duplicate andfield duplicate recoveries outside evaluation criteria. Additionally, data were qualified estimatednon-detect (UJ) for select samples based on high initial calibration deviation for 2,4-dinitrophenol, low calibration verification recoveries for tetryl and reporting limit verificationrecoveries for 2,6-dinitrotoluene, 4,6-dinitro-2-methylphenol, and hexachlorocyclopentadiene.Based on the data reviews and validations, no analytical data was qualified as R (rejected).Acceptable levels of accuracy and precision were achieved for the data and completeness was100% for the Phase II RFI investigation. A complete summary of the data reviews andvalidations are presented in Appendix A.The analytical data for samples collected at the Suspected Propellant Burial Area East of ‘P’Loop (Site 24) were determined to be acceptable (including estimated data) for the intended datause.The nitrotoluene compounds 2,4-DNT and 2,6-DNT were reported using two different analyticalmethods, SW-846 Method 8270C and Method 8330. In some instances, the values reportedusing SW-846 Method 8270C were not comparable to those values reported using SW-846Method 8330. There was not a definitive bias using either method. While some of thediscrepancy may be due to inherent differences between the analytical methodologies (e.g.,8270C), the differences are likely attributable to sample heterogeneity. Contaminated soils areoften extremely heterogeneous. While samples were homogenized in the field and again at thelaboratory prior to analysis, sample homogeneity is particularly difficult to achieve fornitrotoluenes due to their relative insolubility. As a conservative approach, the higherconcentration was used if more than one valid result was reported for any compound.Chemical Investigation ResultsSECTIONFIVE Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 5-1All samples collected from the Suspected Propellant Burial Area East of ‘P’ Loop (Site 24) wereanalyzed for Target Compound List (TCL) SVOCs, Target Analyte List (TAL) metals, andnitroaromatics/nitramines.

Chemical concentrations detected at or above 50% of the calculated, site-specific IndustrialClosure Level (Level 2) values (discussed in Section 7, compared in Tables 7-1 through 7-3, andshown on Figures 6-1 and 6-2) were considered to be elevated. Detected concentrations less than50% of the Level 2 values were considered to be low.6.1 NEAR SURFACE SOILS AND SEDIMENTSThe assessment of chemicals detected in near surface soils and sediments were based on 21samples collected from the top two feet of 19 soil borings and two sediment sample locationswithin and around the burial area (see Figure 2-1).Metals were generally detected in all near surface soil and sediment samples and SVOCs weredetected in two thirds of the near surface soil and sediment samples collected. VOCs weregenerally detected in all near surface soil samples collected as part of the Phase I RI, whilenitrates/nitrites and cyanide were not detected in any near surface soil sample collected as part ofthe Phase I RI. Pesticides were detected in generally all and PCBs in half of the near surface soiland sediment samples collected during the Phase II RFI. There were no detections bynitroaromatic/nitramine analysis, following USEPA Method 8330, in any near surface soil andsediment sample collected during either the Phase I RI or Phase II RFI.6.1.1 VOCsThree VOCs were detected at low concentrations in the near surface soil and sediment samplescollected during the Phase I RI (see Table 5-1 and Figure 6-1). These VOCs were generallydetected below or just above reporting limits, the exception being acetone. Acetone was detectedup to 6 times the reporting limit, but these levels were not considered elevated based on the factthat acetone is a common laboratory contaminant.The presence of these VOCs may be related to landfill and disposal activities at the SuspectedPropellant Burial Area East of ‘P’ Loop (Site 24). The three detected VOCs were used in a riskscreen for soil and sediment in Section 7.2.6.1.2 SVOCsTwenty-four SVOCs, including seventeen polynuclear aromatic hydrocarbons (PAHs), weredetected in the near surface soil and sediment samples (see Table 5-1 and Figure 6-1). Only twoof the SVOCs, 2,4-DNT and benzo(a)pyrene, were detected at elevated levels. 2,4-DNT wasdetected in two near surface soil samples, both at elevated concentrations, and benzo(a)pyrenewas detected in 7 near surface soil samples, with only one elevated concentration.2,4-DNT is a component of both SVOC and nitroaromatic/nitramine analysis (USEPA Methods8270 and 8330, respectively). In the near surface soil samples identified above, 2,4-DNT wasdetected by SVOC analysis, but was not detected by nitroaromatic/nitramine analysis.Contamination AssessmentSECTIONSIX Suspected Propellant Burial Area East of ‘P’ Loop, Site 24Q:\4599\fl010d00\Site 24\Final\Site 24 Secs 1-10 Text_Rev1.doc\16-Apr-03 /OMA 6-2The presence of these SVOCs may be related to landfill and disposal activities at the Su
