INAAP south ash settling basin site 4 report Oct 2002

Description: The revised final report for the south ash settling basin site 4 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. TheSouth Ash 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 South Ash Settling Basin included the completion of 22soil borings; the collection and analysis of 74 surface and subsurface soil samples, 18 collocatedsurface water/sediment samples, and five groundwater samples. Chemical analysis includedvolatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), pesticides,polychlorinated biphenyls (PCBs), metals, cyanide, nitroaromatics/nitramines, and various wetchemistry parameters and geotechnical analyses.The South Ash Settling Basin covers approximately 4.6 acres and was constructed within anaturally occurring topographic low, which forms the uppermost part of Jenny Lind Run. Thebasin intermittently received slurried ash from the south coal-fired power plant from 1941 to1972. It has also received wastewater form the production of nitrobenzene, aniline,Executive Summary South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA ES-2diphenylamine, and dimethylaniline, and may have received nitrocellulose waste (ASI 1994)from the P&E Area.The South Ash Settling Basin is situated in an Upland area characterized by karst topographyassociated with shallow limestone bedrock. The surface of the basin is somewhat hummockyand irregular in shape, but generally slopes to the east.Local surficial geology consists of up to 15 feet of ash underlain by colluvium, residium orlimestone bedrock. Bedrock was encountered at depths ranging from less than one foot bgs tomore than 29 feet below ground surface. The bedrock surface generally slopes from south tonorth. There appears to be significant karst features (sinkholes) in the bedrock surface.Groundwater was encountered from the surface to approximately 12.5 feet bgs.A contamination assessment was completed for near surface soil and sediment, subsurface soil,surface water, and groundwater. Elevated levels of five SVOCs and sixnitroaromatics/nitramines compounds were detected in near surface soil and sediment samples.Three SVOCs and three nitroaromatics/nitramines were detected at elevated levels in subsurfacesoil samples. Elevated levels of target compounds were not detected in surface water andgroundwater samples. Several metals results exceeded background concentrations for all mediasampled. Cyanide results exceeded background concentrations for surface and subsurface soilsamples.Future land use in the South Ash Settling Basin area will be for industrial / commercial use only.Therefore a human health risk assessment evaluated the on-site worker, excavation worker, andhunter scenarios. The results indicate that the potential primary carcinogenic risk drivers areingestion of N-nitrosodiphenylamine (diphenylamine) and carbazole from deer tissue. Thepotential primary non-carcinogenic risk driver is ingestion of N-nitrosodiphenylamine(diphenylamine) in soil/sediment. The cancer risks ranged from 1 x 10-6 to 1 x 10-4 for theRecommended Maximum Exposure (RME) and 4 x 10-8 to 1 x 10-5 for Central TendencyExposure (CTE). Hazard indices ranged from 0.05 to 4.9 for RME and 0.002 to 1.8 for CTE.The South Ash Settling Basin sits within the Jenny Lind Run drainage basin. Downgradientportions of the drainage basin are expected to become part of the existing state park system.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 the SouthAsh Settling Basin. They include the 1st order avian carnivores exposed to total DDT and highmolecular weight PAHs, as well as those cave resources potentially exposed to copper, zinc, andN-nitrosodiphenylamine (diphenylamine) that may be being released to underground springs.Data of sufficient quality and quantity has been collected to characterize the South Ash SettlingBasin. Physical and chemical investigation results indicate that there are potential ecologicalconcerns while human health concerns are less significant. Based on the results of the Phase I RIand Phase II RFI a Corrective Measures Study has been recommended to evaluate variousalternatives to reduce ecological and human exposures to acceptable levels.Site Location and DescriptionSECTIONONE South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 1-1The South Ash Settling Basin (Site 4) is locatedin the west-central part of Indiana ArmyAmmunition Plant (INAAP), at the southern endof the Propellants and Explosives (P&E) Area(see Figure 1-1). The site is situated west of “G”Avenue, south of 12th Street, and east of “D”Avenue.The basin, measuring approximately 1,000 feetlong by 200 feet wide, was constructed within anaturally occurring topographic low, whichforms the uppermost part of Jenny Lind Run.The basin occupies approximately 4.6 acres (ASI 1994) and is oriented roughly east to west. Thewestern portion of the basin contains both grass- and tree-covered areas. The central portion iscovered with trees. The eastern end of the basin is overgrown with tall grass and weeds.South Ash Settling Basin is located immediately downstream from the Aniline Pond (Site 5); anearthen dam in the northwest corner of the basin separates the two sites. There is no flow orsewer connection between the South Ash Settling Basin and the Aniline Pond. A second earthendam, located at the eastern end of the basin, separates South Ash Settling Basin from the JennyLind Run, and serves as a roadbed for “G” Avenue. South Ash Settling Basin dischargeddirectly into the Jenny Lind Run during the facility’s operation.The site is bordered by:· North – 12th Street and South Ash Settling Basin (Site 5)· South – grassland· East – “G” Avenue· West – grassland and former aniline production area.Asphalt roads surround the basin on most of two sides, and grass-covered fields surround theremainder. Buildings from the former aniline production area were located near the west end ofthe basin.1.1 OPERATIONAL HISTORY AND WASTE CHARACTERISTICSThe basin intermittently received slurried ash from the south coal-fired power plant from 1941 to1972. It has also received wastewater from the production of nitrobenzene, aniline,diphenylamine, and dimethylaniline, and may have received nitrocellulose waste (ASI 1994)from the P&E Area. Several chemicals were involved in the production of these organiccompounds including: benzene, nitric acid, sulfuric acid, elemental iron, ferric chloride catalyst,ammonium chloride, methanol, sodium carbonate, an ethyl alcohol-diethyl ether/dinitrotoluenemixture, diphenylamine, and dibutylphthalate.Site Location and DescriptionSECTIONONE South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 1-2“Coal clinker,” ash, and black charcoal-like materials, were observed on the south bank of thebasin (see Figure 1-2) during the site reconnaissance. Similar materials were observed near asteel pipe previously identified as an ash slurry pipe (W-C 1998) at the west end of the basinduring the field sampling activities. A review of a utilities drawing (Map 2645, Sheet 16)indicated that an 8-inch ash pipe running to a sump on the north side of the basin, just south andeast of the Aniline Pond dam (Figure 1-2). A review of a related drawing (Map 2645, Sheet 19)indicated that the South Ash Settling Basin may also have received sanitary waste in thesouthwest corner of the basin from a septic system.A vitrified clay standpipe is located on the east end of the basin (Figure 1-2). This standpipeonce emptied directly into the Jenny Lind Run on the east side of “G” Avenue (Figure 1-2),according to drawing I.O.W.S No. 6047, Sheet 1 of 2).1.2 PREVIOUS INVESTIGATIONSDames & Moore completed a Contamination Survey at the site in 1984 (D&M 1984). However,the analytical methods used at that time are now considered obsolete. Therefore, the historicalanalytical data collected during this survey is not comparable to the data collected, followingcurrent standards, during the Phase I Remedial Investigation (RI) and the Phase II ResourceConservation and Recovery Act (RCRA) Facility Investigation (RFI), and was not used in thisreport.Woodward-Clyde 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 with the results of the Phase II RFI.

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 1996, 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 DIRECT PUSH SOIL, SOIL GAS AND GROUNDWATER SURVEYAs part of the Phase I RI, a direct push soil, soil gas and groundwater survey was completed atthe South Ash Settling Basin in order to identify the presence or absence of volatile organiccompounds (VOCs) in soil, soil gas and groundwater, and to assist in locating additional soilborings. The soil, soil gas and groundwater samples were positioned in a grid pattern, thoughsome sampling points had to be adjusted due to site features. Forty investigative samples werecollected and analyzed onsite for VOCs using a mobile laboratory. The majority of sampleswere collected from a depth of 5 feet below ground surface (bgs). For additional information onthe direct push soil, soil gas and groundwater survey at the South Ash Settling Basin, refer toSection 4 of the Draft Final Phase I RI Report (W-C 1998).2.2 GEOPHYSICAL SURVEYAn electrical resistivity survey was completed as part of the Phase II RFI investigation.Electrodes were spaced at five-foot intervals. The east-west transect was completed in threearrays due to the length of the basin and the short electrode spacing. The results of this surveyare discussed in Section 3.2.2.3 SOIL AND SEDIMENT SAMPLING2.3.1 SoilTwenty-two borings were drilled within the basin. Boring locations were selected based on soilgas, direct-push soil and groundwater sampling results (see Section 2.1), geophysical survey data(see Section 2.2), historical information, and site accessibility. Borings 04SB01 through 04SB12were drilled at the following locations (see Figure 2-1) using hollow stem augers (4 ¼-inch innerdiameter, 8-inch outer diameter) and a 3-inch diameter stainless steel split spoon:· 04SB01 – Along the west edge of the basin· 04SB02 and 04SB03 – Along the south edge of the basin· 04SB04 – Along the north edge of the basin· 04SB05 – In the west-central portion of the basin· 04SB06 – Outside the north edge of the west-central portion of the basinField Activities SummarySECTIONTWO South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 2-2· 04SB07 – Approximately 70 feet southwest of boring 04SB06· 04SB08 and 04SB09 – Near the southeast corner of the basin· 04SB10 – Near the possible basin outlet at the east end of the basin· 04SB11 – Approximately 70 feet east-southeast of the sinkhole· 04SB12 - Approximately 60 feet west-northeast of the sinkhole.Borings 04SB13 through 04SB22 were completed at the following locations (see Figure 2-1)using a direct push system and 1.75-inch diameter polyvinyl chloride (PVC) liners.

However, dueto their relatively shallow total depths to bedrock only two samples were collected from borings04SB03, 04SB14 and 04SB18. Conversely, four samples were collected from borings 04SB16and 04SB17 based on the depth to bedrock. Sample identification, depth, matrix, and chemicalanalysis are presented in Tables 2-1 and 2-2. Boring locations are shown in Figure 2-1.Nine geotechnical samples were collected from the South Ash Settling Basin during the Phase IIRFI. The analytical results from these geotechnical samples are presented in Table F-1 inAppendix F.Field Activities SummarySECTIONTWO South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 2-32.3.2 SedimentNine sediment samples were collected during the sampling activities at the South Ash SettlingBasin. Seven of the nine sediment samples were collected from locations within the basin. Theother two samples (04SD01 and 04SD08) were collected below the basin near the possible basinoutlet. All but one of the sediment samples (04SD07) were collocated with the surface watersamples discussed in Section 2.5. The sediment samples were collected from the followinglocations (see Figure 2-1):· 04SD01 – From beneath standing water in the stream bed on the east side of“G” Avenue· 04SD02 – From beneath water flowing into the sinkhole· 04SD03, 04SD04 and 04SD05 – From beneath standing water in the drainage channelat the bottom of the basin· 04SD06 – From beneath standing water at the northwest end of the basin· 04SD07 – From a topographic low spot approximately 50 feet south of the sinkhole· 04SD08 – From beneath standing water in the stream bed on the east side of“G” Avenue, near the location of 04SD01· 04SD09 – From beneath standing water at the northwest end of the basin, near thelocation of 04SD06Sediment samples 04SD01 through 04SD05 and 04SD07 were collected from 0 to 2 feet bgs.Sediment sample 04SD06 was collected from 0 to 0.5 feet bgs. Sediment samples 04SD08 and04SD09 were collected from 0 to 0.2 feet bgs. Sample location, identification, depth, matrix,and chemical analysis are presented in Tables 2-1 and 2-2.An additional basin sediment sample, collected from 0 to 2.0 feet bgs at location adjacent to04SD06, underwent Toxicity Characteristic Leaching Procedure (TCLP) extraction prior tochemical analysis.2.4 DIRECT PUSH GROUNDWATER SAMPLINGGroundwater samples were collected from direct push borings 04SB13, 04SB15 through04SB17, and 04SB19. Samples also would have been collected from borings 04SB14, 04SB18and 04SB20 through 04SB22; however, water was not encountered in any of these boringsbefore reaching refusal. It was not possible to collect a sufficient quantity of groundwater fromboring 04SB15 during the initial sampling interval. Therefore, in order to obtain a sufficientquantity, the groundwater sample was collected from this location during four intervals over a30-hour period.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.

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 2-1.2.5 SURFACE WATER SAMPLINGEight surface water samples were collected during the sampling activities at the South AshSettling Basin. Six of the eight sediment samples were collected from locations within the basin.The other two samples (04SW01 and 04SW08) were collected below the basin near the possiblebasin outlet. All of the surface water samples were collocated with the sediment samplesdiscussed in Section 2.3. The sediment samples were collected from the following locations (seeFigure 2-1):· 04SW01 – From standing water in the stream bed on the east side of “G” Avenue· 04SW02 – From water flowing into the sinkhole (discussed in Section 3.1)· 04SW03, 04SD04 and 04SD05 – From standing water in the drainage channel at thebottom of the basin· 04SW06 – From standing water at the northwest end of the basin· 04SW08 – From standing water in the stream bed on the east side of “G” Avenue,near the location of 04SD01· 04SW09 – From standing water at the northwest end of the basin, near the location of04SD06Surface water flow to the sinkhole in the north-central part of the basin is intermittent, occurringonly after rainfall and snowmelt events. Surface water was flowing into the sinkhole at the timeof sampling. Therefore, one of the collocated surface water/sediment samples was collectedfrom the sinkhole. Sample identification, depth, matrix, and chemical analysis are presented inTables 2-1 and 2-2. Boring locations are shown in Figure 2-1.2.6 FIELD SCREENING RESULTSField screening was completed during both investigations using headspace analysis. Recoveredsoil from each boring and sediment sample was field screened using a photoionization detector(PID) to verify the presence or absence of organic vapors.

The South Ash Settling Basin issituated in an Upland area characterized by karst topography associated with shallow limestonebedrock. The basin itself was constructed within a topographic low near the head of the JennyLind Run. The surface of the basin is somewhat hummocky and irregular in shape, but generallyslopes to the east.A 1947 study of the effects of acid wastewater disposal on erosion at INAAP (Wickwire 1947)states that the Jenny Lind Run was artificially lengthened from the area of the South Ash SettlingBasin to the dam of the Process Waste Settling Basin located further downstream. A 1995 aerialphotogeologic analysis of the entire facility (ERI 1995) identified a pre-existing lineamentthrough the length of the South Ash Settling. The identification of this lineament was based, inpart, on a 1937 version of the USGS topographic map of the area that was generated prior toconstruction of INAAP.A small, intermittent stream was observed in the basin during the Phase I RI fieldwork. Thisstream, which had an average depth of 0.2 to 0.3 feet, flowed from the west-central part of thebasin to the east-central part, where it emptied into a 6-foot-diameter sinkhole (see Figure 1-2).A small drainage ditch flows south under 12th Street before entering the basin and also emptyinginto the sinkhole (see Figure 1-2); however, this ditch was not observed to contain water duringany of the site visits. Standing water, with maximum depths ranging from 0.3 to 0.5 feet, wasobserved in the tree-covered central and eastern portions of the basin during the January 1995site reconnaissance and during the January and February 1996 sampling event. Standing water,with maximum depths ranging from 0.3 to 0.5 feet, was observed only in the western portion ofthe basin during the October to December 2000 sampling event; the intermittent stream was notpresent at this time.The sides of the basin slope inward, with a drop of several feet to more than 20 feet from theedge to the bottom of the basin. A vitrified clay pipe approximately 2.5 feet in diameter, locatedat the east end of the basin, served as a former outlet for the basin.A review of a historical 1937 U.S. Geologic Survey (USGS) topographic quadrangle map(USGS 1937a) shows that the South Ash Settling Basin was constructed within an existingdrainage. A large elongated depression was observed within the portion of the Jenny Lind Runwhere the basin was constructed. Based on a comparison between the 1937 map and a 1950revised USGS topographic map (USGS 1937b), it appears that the northern side of the basin mayhave been partially filled during the facility’s construction.3.2 LOCAL SURFICIAL GEOLOGYThe local surficial geology has been interpreted based on an electrical resistivity survey, 22 soilborings, nine sediment samples, and the geotechnical analysis of nine soil samples.Physical Investigation ResultsSECTIONTHREE South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 3-2Of the first 12 soil borings drilled during the Phase I RI, bedrock was encountered in six of theborings at depths ranging from 2.6 to 8.1 feet bgs. Limestone bedrock was encountered at 2.7feet bgs in Boring 04SB03, so only two samples were retained from this boring for chemicalanalysis.Borings 04SB13 through 04SB22 encountered refusal at depths ranging from 2.1 to 28.9 feetbgs. Except in the case of boring 04SB16, refusal suggested that bedrock might have beenencountered.As part of the electrical resistivity survey completed during the Phase II RFI, four transects werepositioned across the basin as shown on Figure 2-1. The results of the survey are presented inFigures 3-1 through 3-6. All simplified boring logs from both investigations are presented inFigure 3-5. The interpreted stratigraphy of the basin is depicted in five schematic geologic crosssections shown on Figures 3-9 and 3-10. The locations of the cross sections are shown on Figure3-8. These sections were generated by a qualified geologist from the boring logs usingRockWorks99Ò geologic mapping software. Elevations in feet Mean Sea Level (MSL) on thefigures are based on the North American Vertical Datum of 1988.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:Materials 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 SubsurfaceThe shallow stratigraphy consists primarily of process waste materials and colluvium overlyingresidual soils or limestone bedrock (Figures 3-1, 3-2 and 3-3). The sediments are thickest alongthe north side of the basin due to the infilling of the drainage channel (i.e., topographic low)bedrock surface configuration (Figure 3-3). The bedrock surface within the basin generallyPhysical Investigation ResultsSECTIONTHREE South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 3-3slopes from south to north, as shown on the three north-south resistivity transects (Figures 3-4, 3-5 and 3-6), and slopes toward the center from both the west and east (Figures 3-1 and 3-3). Thelowest point of the bedrock surface coincides with the formation of sinkholes observed on thesurface near the east end of the basin. The locations of these sinkholes are shown on Figure 1-2.The depth to bedrock was deepest on the north side of the basin; bedrock was not encountered atSB16, where refusal was encountered at 28.9 feet bgs.The resistivity transect that spans across the west end of the basin (Figure 3-3) indicates thepresence of subsurface features in the bedrock. These features may be due to buried erosionaltrenches in the bedrock, uneven weathering of the bedrock surface, or the presence of karstfeatures such as buried sinks, voids or solution features.The types of materials generally encountered included a tar-like material (SB01 only) in the westend of the basin, topsoil, ash, colluvium and residual clay soils. Generalized descriptions ofthese materials are listed below:· Topsoil - Soft to stiff, red-brown to brown to olive-gray, moist, low plastic silty claywith occasional ash and limestone fragments, or trace gravel [Unified SoilClassification System (USCS) Symbol CL].· Ash - Loose, dry to wet, brown to gray to black, very fine-grained, poorly graded, andoccasionally containing some coarse-grained material (USCS Symbol ML to SM).Coarser-grained material observed consisted mainly of porous slag material or boiler-typeash.· Colluvium - Soft to medium stiff, light brown to reddish-brown, low plastic clay withsome chert and limestone fragments (USCS Symbol CL).· Residuum - Soft to hard, moist, reddish-brown to gray changing to brown, low tomedium plastic clay (USCS Symbol CL).These descriptions are based on field observations and the results of geotechnical testing.The sediment samples collected consisted of either ash or a mixture of ash and silty clay. Thesoil descriptions are similar to those listed above.Limestone bedrock was observed in outcrop along the southern edge of the basin, just west of“G” Avenue. The outcrop is located in the area marked “Coal Clinker” near the southeast cornerof the basin (see Figure 1-2).3.3 SHALLOW HYDROGEOLOGYThe configuration of the bedrock surface and the subsurface karst features observed on the 1937topographic map appear to coincide with the occurrence of shallow groundwater at the SouthAsh Settling Basin.Physical Investigation ResultsSECTIONTHREE South Ash Settling Basin, Site 4Q:\4599\fl010d00\Site 4\Final\Section 1-10\Site 4 Text_Rev2.doc\5-Apr-02 /OMA 3-4Groundwater was encountered in seven of the 12 borings completed during Phase I RI (February1996) and encountered in five of the ten borings completed during the Phase II RFI (October2000), as shown on the simplified boring logs in Figures 3-7 and 3-8. Shallow groundwater wastypically on top of the limestone bedrock in all areas of the basin with the exception of theeastern end. No groundwater was encountered in the seven borings completed toward the eastend of the basin, even at depths up to 26 bgs (the depth achieved at SB22 using a direct pushsystem). The borings were all located east of the two sinkholes shown on Figure1-2, possiblyindicating groundwater has exited the basin through the sinkholes or other subsurface karstfeature. Surface water reappears approximately 240 feet east of the earthen dam (i.e., the easternedge of the South Ash Settling Basin).RelativeElevation(Feet)1049176453015Distance(Feet)Interpreted Bedrock SurfaceEAST WEST010535061RelativeElevation(Feet)217 329004SB22Refusal = 19 ft BGS04SB21Refusal = 17 ft BGS1040153045617691BoringBoringSITE 4-SOUTH ASH SETTLING BASINELECTRICAL RESISTIVITY IMAGING RESULTSTRANSECT 1, ARRAY 1DRN.

Reporting limits were elevated dueto soil moisture content, which ranged from 16 percent to 47 percent. See the PHASE I RIreport, for a more detailed discussion of the data review issues associated with this investigation.4.2 PHASE II RFIAll chemical data were reviewed following procedures identified in the INAPP Site WideQuality Assurance Project Plan (URS 2000). All VOC data for sample 04-14-DS-00 (and thereanalysis) and antimony data for sample 04-21-DS-00 were qualified rejected based on qualitycontrol (QC) parameters outside evaluation criteria. Some data for the samples collected at theSouth Ash Settling Basin were qualified estimated (J/UJ) based on internal standard, surrogate,LCS or field duplicate recoveries outside evaluation criteria. Additionally, acetone, methylenechloride and bis(2-ethylhexyl)phthalate data for many samples were qualified nondetect (U)based on the presence of these compounds in the trip blank or laboratory method blank samplesor based on professional judgement (common laboratory contaminants). Potassium and thalliumdata for two sediment samples and thallium for one surface water sample were qualifiednondetect (U) based on the presence of the compounds in the laboratory method blank samples.Acceptable levels of accuracy and precision were achieved for the data.
