INAAP process waste settling basin site 6 report Oct 2002

Description:	The revised final report for the process waste settling basin site 6 at Indiana Army Ammunition Plant of Phase II RCRA facility investigation prepared for U.S. Army Corps of Engineers in October 2002.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.

Thereport also summarizes the results of the previously completed Phase 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. TheProcess Waste Settling Basin 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 Process Waste Settling Basin included the completion of18 soil borings; the collection and analysis of 57 surface and subsurface soil samples, 3collocated surface water/sediment samples, 2 surface water samples, and 14 groundwatersamples. Chemical analysis included volatile organic compounds (VOCs), semivolatile organiccompounds (SVOCs), pesticides, polychlorinated biphenyls (PCBs), metals,nitroaromatics/nitramines, total petroleum hydrocarbons (TPH) and various wet chemistryparameters and geotechnical analysis.The Process Waste Settling Basin covers approximately 3.7 acres and was formed by theconstruction of a 20-foot-high dam with a wood overflow structure and spillway across thevalley of Jenny Lind Run. The Jenny Lind Flume carried wastewater from the P&E Area (SiteExecutive Summary Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA ES-263) neutralization facility, nitrocellulose fines, and runoff from the South Ash Settling Basin(Site 4) and the Aniline Settling Basin (Site 5) into the Process Waste Settling Basin. The basinhas received effluent from the P&E Area. Pieces of propellant were observed at the head of thebasin, within the basin, and at the outfall structure.The basin is long and narrow with a stream flowing through the center of the basin. The basinhas been filled in with sediment to the level of the top of dam outflow structure. Thesurrounding ground surface steeply slopes towards the basin and is covered by a thick growth oftrees.It appears that a lineament or fracture extends the entire length of the basin. Local surficialgeology, in order of increasing depth, consists of topsoil (0.5 feet [ft] to 2.5 ft thick), processsediment (3 ft to 21 ft thick) colluvium (1.5 ft to 4 ft thick), alluvium (0.5 to 4 ft thick), andresiduum (less than 6 ft thick) over bedrock (limestone). Depth to bedrock ranged from a fewfeet to over 30 feet. Groundwater was encountered in each boring at approximate depths rangingfrom 0.5 to 1.0 foot below ground surface (bgs).A contamination assessment was completed for near surface soil and sediment, subsurface soil,surface water, and groundwater. Elevated levels of two SVOCs and twonitroaromatics/nitramines compounds were detected in near surface soil and sediment samples.One VOC, two SVOCs and five nitroaromatics/nitramines were detected at elevated levels insubsurface soil samples. Elevated levels of target compounds were not detected in surface watersamples. One VOC was detected at potentially elevated levels in a groundwater sample (seeSection 6.5.1 of the Phase II RFI report). Several metals results exceeded backgroundconcentrations for all media sampled.Future land use in the Process Waste Settling Basin area will be recreational, as part of theexisting state park system. Therefore a human health risk assessment evaluated the on-siteworker, excavation worker, hunter, and child recreator scenarios. The results indicate that thepotential primary carcinogenic risk drivers are ingestion of 2,4-dinitrotoluene and 2,6-dinitrotoluene in soil. The potential primary non-carcinogenic risk driver is ingestion of 2,4-dinitrotoluene, 2,6-dinitrotoluene, and nitrobenzene in soil/sediment. The cancer risks rangedfrom 3x10-9 to 3x10-7 for the Recommended Maximum Exposure (RME) and 2x10-10 to 6x10-8for Central Tendency Exposure (CTE). Hazard indices ranged from 0.000008 to 0.46 for RMEand 0.000002 to 0.23 for CTE. The risk did not exceed the IDEM target level of 1x 10-5 and thecumulative Hazard Index did not exceed the target level of 1.0 indicating that no adverse healtheffects or risks would be anticipated.Several pathways were evaluated as part of an ecological risk assessment. However, the keyecological risk drivers are considered to be those chemicals of ecological concern that appear tohave a potential adverse impact on the more wide-ranging transient receptors of concern whomay receive additional exposures(s) to other areas of potential contamination. These chemicalsof concern have a potential for adverse effects beyond the administrative boundaries of theProcess Waste Settling Basin. They include the carnivores exposed to total DDT, total PCBs andtotal endrin, as well as those cave resources potentially exposed to zinc and cyanide that may bereleased in underground springs.Executive Summary Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA ES-3Data of sufficient quality and quantity has been collected to characterize the Process WasteSettling Basin. Physical and chemical investigation results indicate that there are potentialecological concerns while human health concerns are much less significant. Based on the resultsof the Phase I RI and Phase II RFI a Corrective Measures Study has been recommended toevaluate various alternatives to reduce ecological exposures to acceptable levels.Site Location and DescriptionSECTIONONE Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 1-1The Process Waste Settling Basin (Site 6) islocated in the center of Indiana ArmyAmmunition Plant (INAAP), within the JennyLind Run (drainage basin), between the TruckShiphouses (Site 77) and the Rail Shiphouses(Site 65) (see Figure 1-1), and down streamfrom the Aniline Pond (Site 5) and South AshSettling Basin (Site 4).

There are twostream channels at the east end of the basin, nearthe dam (see Figure 1-2). Much of the basin hasbeen silted in and has become vegetated withgrass and numerous trees and functions as a man-made wetland. A wooden plank (aerating)spillway structure extends from the wood overflow structure on top of the dam to the bed of theJenny Lind Run. During the site reconnaissance and sampling activities, various sizes of solidpropellant were found on the dam and throughout the basin.1.1 OPERATIONAL HISTORY AND WASTE CHARACTERISTICSThe Process Waste Settling Basin has received some portion of every effluent from the P & EArea (Site 63) in addition to lime and gypsum, sludge, nitric and sulfuric acid wastewater (ASI1994). Most of these wastes were discharged to the Jenny Lind Run upstream of the ProcessWaste Settling Basin. In 1953, the Jenny Lind Flume (Site 54) was constructed to carry processwastewater and treated effluent from the P & E Area Sewage Treatment Plan (Site 10) alongJenny Lind Run. The flume emptied onto the ground in Jenny Lind Run just above the ProcessWaste Settling Basin. The flume was constructed primarily of creosote-treated lumber.According to historical drawings, the dam was constructed by placing a 25-foot high concretecore wall set about 8 feet into the ground, the last two feet being set in “firm rock”. Treatedtimber was used to create an aerating spillway on the downstream end. The space beneath thetimber spillway was backfilled with soil for support.1.2 PREVIOUS INVESTIGATIONSDames & Moore completed a Contamination Survey at the site in 1984 (D&M 1984). Sixsediment core samples were collected from the Process Waste Settling Basin. The studyrevealed that organics, metal, and other chemicals were present at all depths sampled (fromground surface to 14.5 feet below ground surface [bgs]). A water sample, which was taken fromthe basin, showed detections of chromium and lead. Nitrate and sulfate were also detected inwater at levels higher than the background samples.Site Location and DescriptionSECTIONONE Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 1-2One sediment and one water sample were collected from below the wooden spillway in theProcess Waste Settling Basin (D&M 1984). Concentrations of nitrate/nitrite and sulfate in thewater were higher than background. In the sediment, cadmium, chromium, and lead werepresent in concentrations above the background. Diethyl phthalate was found in the water, andfluoranthene was found in the sediment sample.However, the analytical methods used then are now obsolete, rendering the analytical datacollected during this survey incomparable to the data collected, following current standards,during the Phase I Remedial Investigation (RI) and the Phase II Resource Conservation andRecovery Act (RCRA) Facility Investigation (RFI); therefore, this data was not used.1.3 REPORT ORGANIZATIONThe remaining portion of this report is organized as follows:· Section 2 – Field Activities Summary· Section 3 – Physical Investigation Results: reviews site topography, local surficialgeology, and shallow hydrogeology· Section 4 – Data Quality Review and Validation: summarizes the results of the 100percent quality control (QC) review and the ten percent full validation· Section 5 – Chemical Investigation Results: identifies the chemical analyses used andfield duplicate samples collected; summarizes the sample detections by sampleidentification number and matrix type in tabular form· Section 6 – Contamination Assessment: presents an evaluation, both in text and onfigures, of chemicals present at the sight in elevated concentrations by matrix andchemical group· Section 7 – Human Health Risk Evaluation: examines the chemicals present invarious matrices at the site to determine if they pose a threat to human health· Section 8 – Ecological Health Risk Evaluation: examines the chemicals present invarious matrices at the site to determine if they pose a threat to the environment· Section 9 – Summary and Recommendations: includes corrective measure studyobjectives· Section 10 – ReferencesFor additional information regarding the rationale for and the objectives of the Phase II RFI,refer to the Sitewide Work Plan (URSGWC 2000a).Field Activities SummarySECTIONTWO Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 2-1Field activities for this site included direct push soil, soil gas and groundwater sampling, andsediment, subsurface soil and surface water sampling. The locations of the sampling points areprovided on Figure 2-1. Sample location, identification, depth, matrix, and chemical analysesare presented in Table 2-1 for samples collected in 1995, and in Table 2-2 for samples collectedin 2000. All field activities were completed in accordance with applicable Standard OperatingProcedures (SOPs) (W-C 1998, URSGWC 2000b). Any deviations from the SOPs are noted onthe Sample Collection Field Sheets (SCFS), provided in Appendix G.2.1 GEOPHYSICAL SURVEYAn electrical resistivity survey was completed as part of the Phase II RFI investigation. Thesurvey included eight transects. Electrodes were spaced at 10-foot intervals. The east-westtransect was completed in three arrays due to the length of the basin and the short electrodespacing. (For additional information, including results, see Section 3.2.)2.2 SOIL AND SEDIMENT SAMPLING2.2.1 SoilEighteen borings were drilled within the basin. Boring locations were selected based ongeophysical survey data (see Section 2.1), historical information, and site accessibility.

Boring locations areshown in Figure 2-1.An additional basin subsurface soil sample (0604SB05), collected from 3.0 to 5.0 feet bgsapproximately two feet east of 06SB03, underwent Toxicity Characteristic Leaching Procedure(TCLP) extraction prior to chemical analysis. This sample was collected during the Phase I RIand is separate from 06SB04 analytical soil and groundwater samples and results.Seventeen geotechnical samples were collected from the Process Waste Settling Basin during thePhase II RFI. The analytical results from these geotechnical samples are presented in Table F-1in Appendix F.2.2.2 SedimentThree sediment samples were collected during the sampling activities at the Process WasteSettling Basin. Two of the three sediment samples (06SD03 and 06SD05) were collected fromlocations within the basin. The third sample (06SD04) was collected below the dam near thebasin outlet. All of the sediment samples were collocated with surface water samples, asdiscussed in Section 2.4. The sediment samples were collected from the following locations (seeFigure 2-1):Field Activities SummarySECTIONTWO Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 2-3· 06SD03 – From beneath standing water in the stream channel near the west end of thebasin· 06SD04 – From beneath standing water, below the wooden spillway, near thelocation of surface water sample 06SW02· 06SD05 – From beneath flowing water in the stream channel, near the west end of thebasin, west of sediment sample 06SD03At the locations of surface water samples 06SW01 and 06SW02, sediment was not present, onlysand and gravel were.

Sample location,identification, depth, matrix, and chemical analysis are presented in Tables 2-1 and 2-2.2.3 DIRECT PUSH GROUNDWATER SAMPLINGFourteen groundwater samples were collected during the Phase II RFI sampling activities at theProcess Waste Settling Basin. No groundwater samples were collected during the Phase I RIfield activities. Groundwater samples were collected from direct push borings 06SB04, 06SB05,06SB07, 06SB09 through 06SB11, and 06SB13 through 06SB18 for all analyses. Only partialsamples were collected from borings 06SB06 (volatile organic compounds and semivolatileorganic compounds [VOCs and SVOCs] only) and 06SB08 (VOCs only) due to limitedgroundwater production from these borings. Water was not encountered before reachingbedrock in boring 06SB12; therefore, a groundwater sample was not collected from this boring.Slotted, PVC standpipes were used during the collection of groundwater samples from all fourborings. Samples for VOCs analysis were collected using a stainless steel minibailer. Prior tothe collection of samples for other analyses, at least 500 milliliters (mL) of water were purgedfrom each boring using a peristaltic pump and designated high density polyethylene (HDPE)tubing. Samples for other analyses were collected using 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 2-1.2.4 SURFACE WATER SAMPLINGFive surface water samples were collected during the sampling activities at the Process WasteSettling Basin. Two of the five surface water samples (06SW03 and 06SW05) were collectedfrom locations within the basin. The other three samples (06SW01, 06SW02, and 06SW04)were collected below the dam at the basin outlet. All of the surface water samples werecollocated with the sediment samples as discussed in Section 2.3.

The Process Waste Settling Basin ischaracterized by karst topography associated with shallow limestone bedrock. The slopesleading down to the basin are steeply angled toward the Jenny Lind Run and covered by a thickgrowth of trees. Trees and grass are present in the basin, and Jenny Lind Run flows generallyfrom west to east through the basin. The Process Waste Settling Basin has been filled in withsediment and materials from the P&E Area to the top of the dam outflow. Water from the basinflows over the dam and drops approximately 25 feet to the bed of the Jenny Lind Run, which hascut approximately 5 feet into the bedrock surface. Jenny Lind Run flows from the Process WasteSettling Basin to the former Jenny Lind Pond.A 1995 photogeologic analysis of INAAP (ERI 1995) reported that a lineament or fractureextends nearly the entire length of the basin. This feature was identified based on a 1937 U.S.Geologic Survey (USGS) topographic quadrangle map (Charlestown quadrangle) of the northernhalf of the facility. The 1937 USGS map also shows that the Process Waste Settling Basin wasconstructed in a valley at the confluence of two existing drainages. Based on historicaldrawings, it appears that the dam and the wooden spillway at the eastern end of the basin werebuilt in approximately 1941.3.2 LOCAL SURFICIAL GEOLOGYThe local surficial geology of this site has been interpreted based on an electrical resistivitysurvey, 18 soil borings, and the geotechnical analysis of 17 soil samples.In general, the shallow stratigraphy at the Process Waste Settling Basin consists of a layer ofprocess waste materials, overlain in places by a thin layer of topsoil and underlain by colluvium,residual clay soils or limestone bedrock. The thickness of process sediment deposits iscontrolled in part by the configuration of the bedrock surface. The depth to bedrock, determinedfrom drilling and the resistivity survey, varies from approximately a few feet along the edges ofthe basin to over 30 feet in the deeper locations.The electrical resistivity of subsurface materials can be affected by a number of differentphysical characteristics. Physical characteristics that act to reduce electrical resistivity includeincreasing water content, increasing salinity of groundwater, increasing clay content, anddecreasing grain size. Additionally, the presence of water-filled voids such as fractures or porespaces and other primary or secondary porosity features lower electrical resistivity.Conversely, an absence or decrease in water content, a decrease in void space, porosity, orfracturing and an increasing degree of compaction or lithification can act to increase theelectrical resistivity. Typical ranges of electrical resistivities of various materials are as follows:Physical Investigation ResultsSECTIONTHREE Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 3-2Materials Resistivity(Ohm-Meters)Wet to moist clayey soil and wet clay 1s to 10swet to moist silty clay soil and silty clay Low 10sWet to moist silty and sandy soils 10s to 1000sWell-fractured to slightly fractured rock with moist,soil-filled cracks100sSand and gravel with layers of silt Low 1000sSlightly fractured rock with dry, soil-filled cracks Low 1000sCoarse, dry sand and gravel deposits High 1000sMassively bedded rock High 1000sNote: Adapted from H.R. Burger, 1992, Exploration Geophysics of the Shallow SubsurfaceA review of the electrical resistivity transects show the bedrock surface varied along the lengthand width of the basin. Transect #1, Array #1 (see Figure 3-1), which started approximately 50feet west of the dam, shows that the bedrock surface is about 23 feet deep. Boring 06SB08 wasdrilled adjacent to the east endpoint of this transect and hit refusal at 24.1 feet bgs. The bedrocksurface rises gradually to the west before reaching the 375-foot mark on Transect #1, Array #2(Figure 3-2).A bowl-shaped depression in the bedrock surface, measuring approximately 36 feet deep,encountered along Transect #1, Array #3 (see Figure 3-3), is centered about 80 feet west of theeast endpoint. This depression may be a collapse feature, or a buried stream channel that hadincised the bedrock surface prior to completion of the dam. An object with a higher electricalresistivity than the surrounding bedrock appears in Figure 3-3 as a large yellow feature beneaththe location of boring 06SB15. The difference in resistivities between this feature and thesurrounding bedrock is low. This feature’s presence can be attributed to natural variations withinbedrock and to the way the software, used to generate the figure, processes data. Based on this,the difference in resistivities has not been interpreted as a void or another significant subsurfacefeature.Transect #2, positioned north-south across the basin (see Figure 3-4), indicates a relatively levelbedrock surface near the west end of the basin. This flat surface may have resulted from the lackof a well-developed stream channel in the bedrock surface at this point, or the transect may havebeen situated above a north-south bend in an old channel.Transects #3, 4 and 5 (see Figures 3-5, 3-6, and 3-7) indicate that the stream channel in thevalley was located on the south side of the basin prior to production activities at INAAP.However, Transect #6 (see Figure 3-8), indicates that the original stream channel had crossedover to the northern side of the valley at some point between Transects #5 and 6. This variabilityin the depth to bedrock from one point in the basin to another has caused the thickness of processwaste materials and other materials in the basin to vary accordingly.Physical Investigation ResultsSECTIONTHREE Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 3-3These sections were generated by a qualified geologist from the boring logs usingRockWorks99â geologic mapping software. Elevations in feet Mean Sea Level (MSL) on thefigures are based on the North American Vertical Datum of 1988.A thin layer of topsoil was encountered in parts of the basin. The topsoil layer includes streamdeposits, and likely, sediments that have washed down the steep valley sides, accumulating alongthe basin’s edges. The depth of the topsoil varies approximately from 0.5 feet to 2.5 feet, asobserved during drilling. The topsoil layer was likely deposited after production stopped at theP&E Area, as trees and grasses have taken hold in the basin.The thickness of process waste materials, as determined by drilling, ranged from approximately3 feet to more than 21 feet. Because of the presence of the stream channel, parts of the basinwere inaccessible to drilling and the resistivity survey. Therefore, the thickest deposits ofprocess waste materials may not have been located. The process waste materials identified in thebasin included clay and silt materials, and a fine-grained sand or ash material.Colluvium includes clay soils not identifiable as either residual soils or process waste materials,and may include alluvial deposits, buried soil horizons, and slope wash. Colluvium generallyappears similar to residual soils, but lacks any soil structures such as a blocky texture, thepresence of iron nodules, manganese staining, or other identifiable features, and may containsmall pieces of twigs and/or leaves. Colluvial soils were identified in three borings (06SB05,06SB10, and 06SB14), all of which were located near the middle of the basin. The colluvialsoils were located near the bottom of the borings and were identified above either alluvialmaterials or the interpreted bedrock surface. Thicknesses ranged from about 1.5 feet to four feet.Alluvium was interpreted to be stream deposited, and included sand and gravel layers. Thethickest alluvial deposits were generally encountered in borings completed at the west end of thebasin (SB16, SB17 and SB18), although thin alluvial deposits were also identified in borings06SB11, 06SB13, 06SB14 and 06SB15. Alluvial deposits were generally one-half to four feetthick.Residuum was encountered in borings 06SB01, 06SB06, 06SB08, 06SB12, 06SB15, 06SB16,06SB 17 and 06SB18. The recorded thicknesses of residual soils were all six feet or less.In summary, the materials encountered were typically described as follows:· Topsoil – soft, medium to dark brown, organic, low plastic, silty clay and clayey silt(USCS symbols CL and ML) with occasional fine sand.· Process waste materials - The clay and silt sediments consist primarily of soft, olivegray to gray to black, low plastic, silty clay to clayey silt (USCS symbols CL to ML).The sandy process waste materials have been classified as loose, wet, black, finegrained silty sand (USCS symbol SM). The sandy process waste materials were onlyobserved in borings SB5, SB8 and SB11.· Colluvium - Soft to very stiff, moist to wet, red to brown to gray-brown mottled, lowplastic, silty clay (USCS symbol CL).Physical Investigation ResultsSECTIONTHREE Process Waste Settling Basin, Site 6Q:\4599\fl010d00\Site 6\Final\Sections 1-10\Sections 1-10 Text_Rev2.doc\15-Apr-02 /OMA 3-4· Alluvium - Loose, gray to brown, wet fine to coarse grained sand to clayey sand,(USCS symbols SP, SC, or SW), some with gravel.· Residuum - Soft to hard, light yellowish-brown to olive-gray/brown mottled to red togray, low plastic to high plastic clay (USCS symbols CL and CH, respectively).The site’s shallow stratigraphy is presented in the simplified boring logs shown on Figure 3-9.The locations of the borings, geophysical survey lines and geologic cross-sections are shown onFigure 3-10. Interpreted geologic cross-sections are included on Figure 3-11. All simplifiedboring logs from both investigations are presented in Figure 3-5.3.3 SHALLOW HYDROGEOLOGYGroundwater was encountered near ground surface in all boring locations at approximate depthsranging from 0.5 feet to 1-foot bgs during the Phase I RI and Phase II RFI. The presence of thedam maintains the shallow groundwater at an artificially high level.A spring is present at the base of the dam along the south side. It is not known whether thespring represents leakage from the settling basin, groundwater from other sources, or acombination of the two. The spring was sampled as part of the spring survey (URSGWC 1998).Total porosities were calculated for 14 of 17 geotechnical soil samples analyzed. Twelve of theporosities reported were for process waste materials, which ranged from 41 to 62 percent, onewas for residual soils, at 51 percent, and one was for alluvial materials, at 30 percent (seeAppendix F, Table F-1).The Process Waste Settling Basin is located downstream of the Aniline Pond (Site 5) and theSouth Ash Settling Basin (Site 4). Groundwater and surface exiting either of these two siteslikely follows along the course of Jenny Lind Run. This groundwater and surface water likelythen enters the Process Waste Settling Basin as groundwater flowing in the underlying saturatedsediments or as surface water flowing from springs in the Jenny Lind Run.RelativeElevation(Feet)Distance(Feet)Interpreted Bedrock SurfaceEAST WEST0 80 160 240 320 400 460Boring06SB07Refusal = 21.5 ft BGSBoring06SB05Refusal = 20 ft BGSSITE 6 - PROCESS WASTE SETTLING BASINTRANSECT 1, ARRAY 1INDIANA ARMY AMMUNITION PLANTDRN.
