CHARACTERIZATION REPORTDAVIS, CALIFORNIA
1.0 INTRODUCTION
Montgomery Watson has prepared this Waste Burial Hole Characterization Draft Report onbehalf of the University of California, Davis (UC Davis) for additional investigation performed atthe former Laboratory for Energy-related Health Research/South Campus Disposal Site(LEHR/SCDS site, Figure 1). This draft report presents the results obtained from the WasteBurial Hole Characterization Work Plan dated December 2000 (Montgomery Watson, 2000).This draft report describes soil and groundwater investigation after completion of a RemovalAction conducted in the former Waste Burial Holes area shown on Figure 2. The WBH InterimRemoval Action (IRA) was completed in November 1999, documented in the Draft Final WBHRemoval Action Report dated July 21, 2000, and subsequently approved by the United StatesEnvironmental Protection Agency (US EPA) on August 11, 2000.
This investigation and this draft report complies with requirements of the Scope of Work (SOW)in the Administrative Order on Consent (AOC) issued by the US EPA on September 30, 1999.The AOC is issued under the authority of the Comprehensive Environmental Response andLiability Act (CERCLA). UC Davis has prepared and revised a comprehensive Field SamplingPlan (FSP) (Dames & Moore, 1998b), Quality Assurance Project Plan (QAPP) (Dames & Moore1998c), and Health and Safety Plan (HSP) (Dames & Moore, 1996), which are also part of theRemedial Investigation and Feasibility Study Work Plan for remediation investigation andconstruction activities at the LEHR/SCDS site. The FSP, QAPP and HSP have been reviewed bythe U.S. EPA and served as project guidance documents for implementation of the WBH WorkPlan.
1-1 PurposeThe purpose of this investigation is to evaluate surface soils for, hazardous waste characteristics &< Qand evaluate the constituents of concern' (COC's) in soils beneath the previous WBH waste. Data 'collected from this investigation, in conjunction with previous investigation and post IRAexcavation data, is used to evaluate the potential for additional impacts to groundwater as part ofthe Remedial Investigation and Feasibility Study for the site.

\\Ussacls-ifosvr\sacindustrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc
2.0 BACKGROUND AND PREVIOUS INVESTIGATIONS
2.1 BackgroundBased on historical records, low-level radioactive waste material was disposed in 49 burial pits orwaste burial holes (Figure 2) between 1956 and 1974 (Dames & Moore, 1999). According to therecords, each burial pit was approximately 4 feet by 4 feet in area and extended to a depth ofapproximately 10 feet below ground surface (bgs). In general, the waste consisted of vials,syringes, laboratory glassware, and animal carcasses. After disposal, holes were covered with alayer of native silty fill material.
Two groundwater monitoring wells (UCD1-13 and UCD2-14), located down gradient of theWBHs have shown elevated concentrations of tritium and carbon-14 in groundwater. The tritiumand carbon-14 detected in groundwater appears to be localized and has not been observed in otherwells (URS, 2001). Based on these findings, several soil and soil gas investigations were initiatedfrom 1988 to 1998 to characterize potential sources to groundwater located in the WBH area.
2.2 Previous InvestigationsTwo reconnaissance trenching programs (Wahler, 1988; Dames and Moore, 1990), a soil gasinvestigation (PNL, 1995), and a trenching and soil sampling program (Dames and Moore,1998a) were completed in the WBH area. Prior to the removal action conducted in 1999,approximately twenty-five soil and eleven soil-gas samples were submitted for analysis.
2.3 Previous Investigation ResultsAnalysis of soil and soil gas samples collected from the WBH area prior to the IRA suggests thatthe most significant contaminants observed in this area were radionuclides. Tritium and carbon-14 were reported at concentrations above background. Previous soil, soil gas, and waste sampleresults are presented in Appendix A.
Previous investigation of the former WBH area focused on characterizing the upper 10 feet ofwaste material, which was removed during the WBH removal action. One soil boring, SB-32(Figure A-l), was advanced below former wastes to a depth of 35 feet bgs. Sample data from thisboring shows the highest activity for all parameters was detected at 6.5 feet bgs in waste(Appendix A). Below the waste, concentrations for all constituents declined sharply with depth(Appendix A).
During the removal action in 1999, commingled soil and waste were segregated and the sortedsoil was used as backfill. The locations of the "sorted soil" are shown in plan view on Figure A-2. During the IRA, samples from the sorted soils were analyzed for tritium, carbon-14 and forhazardous waste constituents. Analysis of soil samples shows residual tritium and carbon-14
\\Ussacls-ifosvi\sacindustrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 5
activities well below the EPA Preliminary Remediation Goals (PRGs) for residential soils fortritium and carbon-14.
Soil samples were collected from the base of each excavation and were tested for tritium andcarbon-14 during the BRA (Figure A-3). Based on the results reported, none of these samplesexceed PRGs for either tritium or carbon-14.

3.0 METHODS
The field program described in this report complied with the approved WBH Work Plan. Detailsof the QAPP, FSP, and HSP were followed except where noted in the WBH Work Plan. GeneralEngineering Laboratories Inc (GEL), located in Charleston, South Carolina, conducted alllaboratory analyses.
The WBH Removal Action was designed to remove low level radioactive waste (LLRW), debris,and other source material potentially impacting groundwater. Following waste removal, soil andgroundwater samples were collected within and beneath former waste burial holes area. Thesamples were analyzed for hazardous waste constituents and COC's to evaluate potential forresidual migration of COC's to groundwater.
3.1 Modifications to the Work PlanConditions in the field required minor modifications to the WBH Work Plan. Thesemodifications from the WBH Work Plan were relatively minor and did not subtract form thescope of work presented in the WBH Work Plan. All modifications utilized methods hi theapproved FSP. The three modifications from the WBH Work Plan included modifying the in-situwater sampling method, extending the depth of soil borings SBL-390 from 19 to 40 ft bgs, andcollecting a duplicate sample from SBL-399 rather than SBL-396. These modifications areexplained in greater detail below:
1) In-situ groundwater samples from the borings SBL-395, SBL-393 and SBL-391 (see Figure 4for locations) were collected as in-situ borehole groundwater grab samples, according to SOP1.2.3 In-situ Groundwater Sampling, in place of the Hydropunch method. The hydropunch wasattempted in all five locations but failed to produce sufficient groundwater at SBL-391, -393, and-395. Evidently, hydropunch sampling at these locations failed due to high clay content and thinsand lenses encountered. The ™hydropunch method was successful in locations SBL-399, andSBL-396.
2) Boring SBL-390 was advanced to 40ft bgs with continuous core instead of 19ft bgs. The depthwas increased to better characterize the stratigraphy at the western portion of the WBH area. Theboring was moved 2, feet to the south to allow enough room for the drilling equipment.
3) A duplicate groundwater sample was collected from SBL-399 instead of the duplicate plannedfor SBL-396. This change was made because their was insufficient groundwater available inlocation SBL-396 to collect a duplicate.
\\Ussacls-ifosvAsacindustrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc
3.2 Soil Borings to Ground WaterAll soil borings shown on Figures 4 and 5 were drilled using hollow-stem auger techniquesaccording to SOP 6.0 - Soil Borings. Five borings were completed to groundwater.Groundwater samples from the borings were collected from locations SBL-396 and SBL-399using the ™hydropunch method. In-situ groundwater grab samples were collected at locationsSBL-391, -393, and -395. All five borings produced enough water for sampling and groundwatersamples were collected at all five locations as planned. Two continuous core borings werecompleted to groundwater SBL-390 and SBL-399. The remaining 5 borings were terminated at20 feet bgs. Each soil boring was logged by a qualified geologist according to the Unified SoilsClassification System (USCS) as outlined in SOP 7.0 - Logging of Soil. The boring logs arepresented in appendix B.
3.3 Shallow Borings from 2 to 6 Feet bgsThe shallow 2 to 6 ft bgs borings were completed using hollow-stem auger techniques accordingto SOP 6.0 - Soil Borings. Twenty-one shallow borings were completed and samples collectedfrom the bottom of each boring.
All soil samples were collected in 6-inch long by 2-inch diameter stainless steel sleeves, asdescribed in SOP 6.0. All soithe manufacturer instructions.described in SOP 6.0. All soil samples were subsampled for VOC's using the En-Core™ using
3.4 Quality Assurance/Quality Control/ Data ValidationAn integral part of the WBH sampling and analysis plan is the QA/QC program to ensure thereliability and compatibility of all data generated during the investigation. The field andlaboratory procedures prescribed in the RI/FS QAPP (Dames & Moore, 1998) were employed forverifying and maintaining performance quality during the collection and chemical analysis of soiland grab-groundwater samples. The analytical methodology used for sample analysis wasconsistent with the methods employed during other investigations at the site.
The data generated by GEL were subjected to data validation. The analytical data was validatedaccording to the procedures presented in the RI/FS QAPP. The data validation proceduresprovide quality criteria for evaluating precision, accuracy, representativeness and completeness.For some analytical results, quality criteria were not met and various data qualifiers were added toindicate bias introduced during sampling handling or analyses. These data qualifiers arepresented along with the analytical data at the end of the tables section. Data qualified asestimated (J/UJ) exhibited some bias during analysis and should be considered an approximatemeasure of the respective analyte concentration. Data qualified, as anomalous (U) should beconsidered not detected above the adjusted laboratory-reporting limit. Data qualified as rejected(R) are not useful in determining the presence or absence of the respective analyte.

4.0 RESULTS
The purpose of this investigation as stated in Section 1.2 is to further characterize surface soils forhazardous waste characteristics and subsurface soils for residual concentrations of constituents ofconcern (COC's) that could continue to impact ground water. In-situ groundwater samples werealso obtained to evaluate current groundwater conditions relative to downgradient monitoringdata, and to compare groundwater quality with soil analytical data.
As presented in Table 1A, and shown on figure 3 surface soil samples were collected in three .-, .,types of soil: sorted, 2ft-overburden and overburden soils the distinction between these soils is f~) flpriy\ ^^discussed in the WBH Characterization Sampling Work Plan. The depth of the soil borings "~~"ranged from 2 to 6ft bgs. The surface soils were composited as indicated on Figure 3 andanalyzed for COC's and hazardous waste constituents listed on Table IB and 1C. Groundwatersamples were analyzed for COC's listed in Table ID. The analytical methodology used forsample analysis is consistent with the methods employed during other investigations at the site.These methods, compounds, detection limits, and quality control measures are detailed in theWBH Characterization Sampling Work Plan (Montgomery Watson, 2001 and in the LEHR/SCDSQAPP).
4.1 Hazardous Waste ConstituentsAll 21 shallow soil samples (locations shown onjjigure 4) were analyzed for the full list of VOCsin soils, with the results presented in Table ,2A._J The 21 individual-samples were grouped bysample ID, composited by the laboratory and submitted for ^non-volatile.- hazardous wasteconstituents (metals, pesticides, semi-volatiles, general chemistry, corrosivity, ignitibility, andreactivity). The results for the composite samples are presented in Tables 2B.
4.1.1 MetalsTo determine hazardous waste characteristics, total metals and select total organic constituentswere compared against the TTLC, 10 times STLC, and 20 times TCLP. To achieve thecomparison for totals against the STLC and TCLP dilutions factors must be factored in, thereforthe 10 and 20 times factors.
Nickel and chromium HI are the only metals over the STLC regulatory limits. Nickel andchromium III are below background, TCLP and TTLC regulatory threshold concentrations.Chromium VI, lead, selenium, silver and zinc are above background but below hazardous wastethresholds of TCLP, TTLC and STLC. All other metals analyzed are below background andregulatory thresholds for hazardous waste. The results are shown in Table 2B and Table 5.
\\Ussacls-ifosvr\sac industrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc'
4.1.2 Semi-Volatile, Volatile Organics, Pesticides and PCB'sAll seven composite samples were analyzed for semi-volatile and volatile organics, pesticides andPCB's and the results are presented in Table 2A and 2B. Out of all semi-volatile, volatileorganics, pesticides and PCB compounds analyzed none are above regulatory limits for TTLC,STLC and TCLP. The volatile organics, pesticides and PCB are sporadically detected throughoutall soils in the WBH area.
The sporadic detection of VOC's, semi-volatiles, pesticides and PCB are consistent with previousinvestigation results.
4.1.3 Reactivity, Ignitibility and CorrosivityThe general chemistry parameters listed in Table 2B include pH, reactive releasable cyanide,reactive releasable sulfide, ignitability, Nitrate-N and TDS. The pH ranged from 7.9 to 8.1. ThepH range is consistent with native soils in the Davis area. The reactive releasable cyanide wasdetected in one of the seven samples at 22ug/Kg. The reactive releasable sulfide was not detectedin any sample above the method detection limit. Ignitability was below the 200°F threshold.
4.2 Constituents of ConcernThe results of COC's (tritium, carbon-14, nitrate-N, TDS, chromium, chloroform and VOCs) inthe soil borings are presented in Table 2B and Table 3. Tritium is reported above background butbelow the residential PRG of 1 l,OOOpCi/g. Total tritium in the soil samples ranged from 2.7pCi/gto 455pCi/g. The highest value of dissolved tritium (10,500pCi/L) was reported hi SBL-375. Theaverage dissolved tritium is 55 percent of the total tritium. Both total and dissolved tritium valueswhere lowest hi the overburden and 2-ft overburden and highest in the sorted soil. Tritiumconcentrations are lower in the surface soils then the subsurface soils. All soil tritiumconcentrations are considerably lower then previous investigation results.
Carbon-14 is reported above background but below the residential PRG of 770pCi/L. Both totaland dissolved carbon-14 values are lowest in the overburden and 2-ft overburden and highest inthe sorted soil. Carbon-14 concentrations are higher in the surface soils than the subsurface soils.The average percent soluble carbon-14 from the total carbon-14 is 26 %. Hexavalent chromiumconcentration in soil is greater then background, but well below the PRG value.
4.3 In-Situ Groundwater SamplesAll five hydropunch samples show carbon-14 concentrations. Carbon-14 ranges from 103pCi/L inHP-393 to 785pCi/L in sample HP-396 (Table 4). The carbon-14 concentrations in theHydropunch samples are much lower then the concentrations in well UCD1-13. Carbon-14 rangein well UCD1-13 is 900pCi/L to 2500pCi/L. Carbon-14 concentrations are above the backgroundof50pCi/L.
\\Ussac 1 s-ifosvr\sac industrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 10
Tritium is detected in all five samples. In one sample HP-396 tritium is detected at 36,500pCi/L.Sample HP-396 is above background and the MCL of 20,OOOpCi/L. The range of tritium in wellUCD1-13 is 9000pCi/L to 30,OOOpCi/L.
Chloroform is detected in three out of the five samples. Chloroform ranges from 0.19ug/L insample HP-396 to 1.3ug/L in sample HP-391. Nitrate is also detected in all samples ranging fromllmg/L to 41mg/L in HP-391 and HP-395 respectfully. Nitrate is above backgroundconcentrations of 27.4mg/L. 1,2-Dichloropropane is only detected in HP-399 at 0.16ug/L. Allother samples are below the detection limits. The other VOC's, 2-butanone, acetone, benzene,methylene chloride and toluene are below the detection limits.

5.0 DISCUSSION
The data collected in this investigation provides a comprehensive evaluation of the chemical andradiological quality of surface soils, subsurface soils, and groundwater in the WBH area. Thissection will evaluate the hazardous constituents in surface soils in the WBH area, and discuss thepotential for residual concentrations of COCs in soils to impact groundwater.
5.1 Surface SoilThe surface soil analytical data is presented in Tables 2A and 2B. Table 5 presents a comparisonof the range of WBH surface soils data compared to site background (Weiss, 1998), hazardouswaste criteria (CCR Title 22 Section 66261.24-), and Region 9 Prelininary Remediation Goals(PRGs)(EPA, 2000).
As shown on Table 5, none of the surface soil samples exceed hazardous waste characteristics. Alimited number of constituents (lead, tritium, carbon-14), exceed estimated background soilconcentrations, and only arsenic exceeds the PRG, although background arsenic concentrationsalso exceed PRGs. These comparisons demonstrate that the sorted soils and overburden materialdisturbed during the WBH Removal Action do not constitute a waste or apparent, health risk,although risks associated with these data will be evaluated more thoroughly in the Site Wide RiskAssessment. It should be noted that all WBH surface soils are covered with a six-inch layer ofclean imported fill, compacted and sloped to drain away from the WBH area (Dames & Moore,2000).
5.2 Groundwater QualityThis section evaluates the groundwater quality data below the WBH area relative to historicupgradient, and downgradient groundwater quality data from monitoring wells collected from1990 to the present. The purpose of comparing these current groundwater samples togroundwater monitoring data is to attempt to observe trends in groundwater quality and to makequalitative comparisons groundwater quality in the WBH area.
5.2.1 Comparisons to Background, and Downgradient Water QualityQuantitative comparisons of water quality between in-situ borehole groundwater grab, or
Hydropunch™ samples and monitoring well samples are not appropriate, but qualitativecomparisons of trends can be made. As noted in Section 3.0, in-situ borehole groundwatersamples are generally turbid and are not purged to obtain formation water similar to monitoringwell samples.
The table below presents in-situ groundwater concentration ranges observed in background(UCD1-18), WBH in-situ groundwater samples and downgradient monitoring data from UCD1-

1 - Montgomery Watson, 2001 - Background Concentration Study HSU-1ND - Not detected
This summary table shows that groundwater beneath the WBH area is impacted for all COCscompared to background concentrations observed in UCD1-18. WBH in-situ groundwatersamples also exceed the concentrations observed in downgradient well UCD1-13 in many, but notall cases. The data presented in the table above and in Table 4 further justifies the recent removalof wastes in the WBH IRA (Dames & Moore, 2000).
5.2.2 Current and Historic Groundwater QualityTable 4 and the summary table presented above show that groundwater is impacted, beneath theWBH area, additional analysis of the data is needed to evaluate the magnitude of the impactsrelative to historic groundwater quality downgradient of the WBH area. Appendix C presentstime versus concentration graphs for COCs in well UCD1-13. These graphs show a decreasingtrend over for tritium and carbon-14 in UCD1-13, with relatively more consistent concentrationsfor TDS, nitrate-N, chromium, and chloroform over time in well UCD1-13.
Inspection of the time versus concentrations graphs in Appendix C suggest that historic impactsfrom the WBH wastes (especially tritium and carbon-14) to groundwater have peaked and arebeing attenuated through radioactive decay, dispersion and natural attenuation. An interperetivesummary of variablility associated with the current WBH in-situ groundwater data relative tobackground, and downgradient HSU-1 conditions for each COC is presented below:
• Tritium was below the reporting limit in 4 out of 5 samples, but the one reported detection(36,500+1050 pCi/L) was above the MCL (20,000 pCi/L), and roughly equivalent to thehighest reported activity in 1990, in downgradient well UCD1-13;
• Carbon-14 activity was reported in all five samples above background well UCD1-18, butbelow activities observed in downgradient well UCD1-13;
• TDS concentrations were consistently higher than background well UCD1-18. 3 out 5samples were higher than historic TDS data from downgradient well UCD1-13;
\\Ussacls-ifosvr\sacindustrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 13
• Nitrate-N concentrations were higher than background well UCD1-18; 3 out of 5 sampleswere higher than historic TDS data from downgradient well UCD1-13;
• Chromium concentrations were higher than background well UCD1-18 in 3 out of 5 samples,but well below concentrations reported in downgradient well UCD1-13; and
• Sporadic, low reported detections (below 2.0ug/L) were observed for chloroform and otherVOCs.
Comparing the current data to the groundwater monitoring data, the groundwater in the WBHarea was a historically significant source of impacts, but these impacts are localized and havediminished over time (1990 to the present). Based on the placement of wastes in the WBH areain the late 1950s to 1974, and tritium's 12.3 year half-life, 2.5 to 4 half-lives for tritium havealready occurred, reducing tritium levels by 75% (2 half-lives) to 94% (4 half-lives).
Treatment technologies for tritium in soil and groundwater are not available at this time.However, natural radioactive decay is a significant attenuation mechanism at this site as discussedabove.
Levels of carbon-14 are consistent, but relatively low compared to activities observed indowngradient wells. These results suggest a release from the WBH area has occurred, but thatdispersion and natural attenuation is continuing to reduce concentrations in downgradient wells.
TDS, nitrate, chromium are also present in groundwater upgradient and downgradient of theWBH area. These constituents are being captured and addressed by the Groundwater IRAsystem.
5.3 Subsurface SoilsThe discussion presented above suggests that groundwater is impacted above background levelsfor tritium and carbon-14, with concentrations for nitrate and TDS, chloroform, VOCs, andchromium, are roughly equivalent to, or only slightly above background levels. These findingsare consistent with the types of wastes (LSC vials containing tritium, carbon-14, biologicalwastes), that were removed from the WBH area (Dames & Moore, 2000).
5.3.1 COCs in Subsurface SoilsThis section will now discuss the potential for native soils below the former WBH wastes tocontinue to impact groundwater. This evaluation will include an analysis of the subsurface soilsdata using the Designated Level Methodology (DLM)(RWQCB, 1989) to predict impacts togroundwater from remaining soil.
Following the DLM analysis, a simple one-dimensional model designed to simulate theinfiltration of rainfall will be presented to support the DLM analysis. The purpose of modeling
\\Ussacls-ifosvi\sac industrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 14
rainfall infiltration is to estimate the velocity of rainfall and provide a qualitative estimate formobile COCs (tritium, nitrate) percolating through the vadose zone. This simulation was notintended to quantitatively estimate constituent migration. The model selected for the rainfallinfiltration simulation is the Hydrologic Evaluation of Landfill Performance (HELP) Version 3(USAGE, 1997, Appendix D).
Table 3 presents the total and WET extract (deionized water) results for the COCs; includingtritium, carbon-14, nitrate, TDS, chloroform and VOCs. COC concentrations in the surface soils(Table 2) were similar to concentrations in the subsurface native soils data presented in Table 3,with the exception of TDS, which was higher in WET extracts in surface soils than in subsurfacesoils.

5.3.2 Designated Level MethodologyThe DLM is straightforward when WET data are available from the soils or solid waste
samples. The basic processes used in the DLM are as follows:
1) Identify a water quality goal (background, basin plan objective, MCL etc.) for eachconstituent;
\\Ussacls-ifosvr\sacindustrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 15
2) Identify an environmental attenuation factor (100 is used as a default for fine-grained soilswith 30 feet or more to groundwater);
3) Calculate a Site-Specific Soluble Designated Level (SSDL) using the equation:SSDL= water quality goal x environmental attenuation factor -r 10.Note division by 10 compensates for the 10-fold sample dilution conducted as part of theWET procedure.
4) Compare the SSDL to the WET data collected from the site.5) If the WET data exceeds the SSDL, the residual impacts represent a potential to impact
groundwater. If the WET data is less than the SSDL, the environmental attenuation factor isadequately protective to prevent additional groundwater quality degradation beyond the waterquality goal.
A DLM analysis is conducted on the surface and subsurface soil data, and the results arepresented in Table 6. A brief summary of the water quality goals and the environmentalattenuation factors used for this analysis is presented below.
Water Quality GoalsThe water quality goals for nitrate, TDS and chromium were set at background concentrations inHSU-1. Background upper tolerance limits for HSU-1 background well UCD1-18 were recentlycalculated (Montgomery Watson, 2001), and these data were used for nitrate, TDS andchromium. The analytical method detection limits were selected for carbon-14, chloroform, andother VOC's. In choosing water quality goals the most restrictive applicable, waster quality goalsshould be selected for deriving designated levels. In this analysis background concentrationswere used because they were the most restrictive.
The water quality goal for tritium was set at the MCL, which is 20,000 pCi/L. The MCL ratherthan background was selected for the following reasons. Tritium impacts to groundwater havebeen adequately characterized by the current monitoring well network. Tritium levels hidowngradierit well UCD1-13 were originally three times the MCL in 1990, and have beensteadily declining for the last 10 years to levels near the MCL. Tritium impacts are limited intheir lateral extent to the well pair UCD1-13, and UCD2-14. Finally, there is no remediationtechnology capable of treating tritium in soil or groundwater. Excavation to and beneath thegroundwater table (approximately 40 feet bgs) and off-site disposal would be the only option.
Environmental Attenuation FactorThe DLM analysis was conducted with two environmental attenuation factors (EAF), the firstusing the default EAF equal to 100, for the Central Sacramento Valley, and the second DLManalysis with a more conservative EAF equal to 10. The default EAF of 100 is used for siteswhere vadose zone materials have significant clay content (>10 to 20% clay), and groundwater ismore 30 feet bgs (RWQCB, 1989,). The WBH area meets the criteria for default EAF equal to
\\Ussacls-ifosvr\sacmdustrial\Project\LEHR\WBH_Misc\WBHDrft7_9 .doc 16
100, based on the soils encountered, (Appendix B) and the depth to groundwater, encounteredbetween 40 and 45 feet, although groundwater level fluctuates.
This investigation was conducted between March 26 and 30, 2001, when groundwater levels inHSU-1 reach their peak. Since wastes buried from 4 to 10 feet bgs, at least 30 feet of soilsseparate the wastes and average groundwater levels. These conditions justify the defaultconditions associated with an EAF equal to 100. However, because historic groundwater levelsmay have risen to less than 30 feet bgs, a second EAF equal to 10 was also evaluated in a secondDLM analysis.
DLM AnalysisTable 6 presents the results of the two DLM analyses. Based on the DLM parameters and theWET analyses, no additional impacts to groundwater are anticipated based on the residualconcentrations of constituents in soils assuming an EAF of 100.
When the EAF was reduced from 100 to 10, only 1 of 13 samples failed to meet the SSDLstandard for one of the 6 COCs. The WET result for TDS in composite sample SBL-377 wasnearly than 3 times higher than any other sample result, and failed the SSDL for TDS when theEAF was 10. One additional sample for chloroform SBL-392 (0.53 ug/L) exceeded the SSDL forchloroform of 0.5 ug/L although the duplicate for this sample, SBL-392D (0.44ug/L) did notexceed the SSDL, when the EAF was 10.
These results suggest that the residual impacts currently present in soils will not impactgroundwater above background, with the possible exception of tritium, whose water quality goalwas set at the MCL, rather than background. These data show that buried wastes in the WBHarea between 1956 and 1974 migrated to groundwater through infiltration of rainfall, andfollowing waste removal, residual impacts from would not be expected to continue to cause animpact to groundwater beyond previous levels.
Modeling Rainwater InfiltrationAppendix D presents the results of two simulations of rainfall infiltration through soils before andafter wastes were removed from the WBH area. The model employed for these simulations isHELP 3, a simple model that simulates infiltration, runoff, evapotranspiration, and change hi soilmoisture storage, using site-specific daily weather data (temperature, precipitation, solarradiation), via a simple water balance approach. HELP 3 simulates unsaturated soil moisturetransport using multiple soil layers, compacted soils, and geo-synthetic liners (not used in thisanalysis) to design landfill caps and subsurface drainage liners and leachate collection systems.HELP 3 was selected primarily because it uses site-specific climate data (Davis weather station,with daily weather information from 1974 to 1999), has a large inventory of soil types, and isfocused in predicting infiltration, rather than relying on assumed infiltration rates.
\\Ussacls-ifosvr\sac industrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 17
The first simulation is intended to evaluate rainfall infiltration following waste burial prior to theWBH Removal Action conducted in 1999. Appendix D describes the model input and output.Prior to waste removal in 1999, HELP 3 predicts that an annual infiltration rate of approximately11 inches per year. Based on an average porosity of the subsurface (40%), the depth of thewetting front would reach approximately 2 feet per year. This suggests that water in contact withwastes at approximately 8 feet bgs, in 1970, would reach the groundwater table at 35 feet bgs inapproximately 12.6 years, in approximately 1983. This suggests the most mobile compoundsincluding tritium, were flushed through the WBH area into groundwater in the mid to late 1980's.This prediction is consistent with downgradient groundwater data, which suggests that levels oftritium in HSU-1 groundwater peaked in the early 1990s and have been steadily declining from1990 to the present.
A second model run was completed in order to simulate rainfall infiltration following wasteremoval, backfill and compaction of excavated soil, and placement of a sloped, compacted soilcap. This second model run predicts an 80% reduction in rainwater infiltration due to soilcompaction during backfill, surface soil grading to facilitate runoff and the placement of acompacted soil cap. Based on the 80% reduction in infiltration, and the removal of wastes,potential migration of constituents present in soil to groundwater has been significantly reduced.

6.0 CONCLUSION
This WBH Characterization Sampling Report has provided analytical data from disturbed surfacesoils, undisturbed soils beneath the former wastes and in-situ groundwater samples from theWBH area.
The surface soils were tested for a full suite of organic and inorganic analytes. As the majority ofthis soil was disturbed soil during the WBH IRA, testing has focused on addressing whether itcontained hazardous waste characteristics. Results showed that surface soils are impactedprimarily with tritium and carbon-14, are not hazardous and concentrations of site COC's are wellbelow PRGs (except for arsenic, present at background levels). Further evaluation of risksassociated with the WBH area will be addressed in the Site Wide Risk Assessment.
Five in-situ groundwater samples were obtained from the WBH area at 40 to 45 feet bgs. One offive in-situ groundwater samples from the WBH area, had reported tritium concentrations abovethe MCL. Concentrations of other COCs were also reported at or below background, with theexception of TDS, which was consistently higher than background. Based on time versusconcentration data from well UCD1-13, located 200 feet downgradient of the WBH area, COCsin groundwater are approaching background in most cases.
Ten subsurface soil samples were collected beneath the former wastes and analyzed for total andsoluble COCs by the WET method using deionized water. The DLM was used along with theWET data to evaluate residual impacts of subsurface soils to continue to impact groundwater.This DLM evaluation and the WET data from the site suggest that residual concentrations ofsurface and subsurface soils will not continue to impact groundwater above background levels orMCLs (for tritium). In addition to the DLM evaluation, an evaluation of rainfall infiltrationsuggests that soil compaction, surface grading and placement of a compacted soil cap completedas part of the 1999 WBH IRA reduced infiltration of rainwater by an additional 80%.
Based on the results of this investigation, the WBH IRA has been successful in removing thewaste materials and past sources to groundwater hi the WBH area. Based on the DLM analysis,residual concentrations of COCs in soils do not appear to impact groundwater above backgroundlevels with the exception of tritium. The DLM suggests that WBH area soils will not contributetritium beyond the MCL. Tritium levels in UCD1-13, have steadily declined since 1990 and havebeen below the MCL's since the mid-1990s due to radioactive decay and dispersion and areanticipated to decline more rapidly now that the source has been removed from the WBH area.
The condition of the WBH area and the improving groundwater quality will be demonstrated inthe on-going quarterly monitoring program in place for UCD1-13. In the unlikely event thathistoric groundwater quality trends of improving groundwater quality are reversed, any
\\Ussacls-ifosvi\sac industrial\Project\LEHR\WBH_Misc\WBHDrft7_9.doc 19
outstanding issues associated with the WBH area will be addressed in the Remedial Investigationand Feasibility Study.

LEHR QUALIFIERS AND REASON CODE DEFINITIONS
REASON CODESa Analytical sequence deficiency or omission.b Gross compound breakdown (4,4-DDT/Endrin).c Calibration failure; poor or unstable response.d Laboratory duplicate imprecision.e Laboratory duplicate control sample imprecision.f Field duplicate imprecision.g Poor chromatography.h Holding time violation.i Internal standard failure.j Poor mass spectrographic performance.k Serial dilution imprecision.1 Laboratory control sample recovery failure.m Matrix spike/matrix spike duplicate recovery failure.n Interference check sample recovery failure.o Calibration blank contamination (metals/inorganics only).p Preparation blank contamination (metals/inorganics only).q Quantitation outside linear range.r Linearity failure in initial calibration.s Surrogate spike recovery failure
(GC organics and GC/MS organics only),t Instrument tuning failure.u No valid confirmation present (GC Organics only),v Value is estimated below the MDA (Rads only).w Retention time (RT) outside of RT window,x Field blank contamination,y Trip blank contaminationz Method blank contamination.Q No valid confirmation column (GC Organics only)
DATA QUALIFIERS
U The analyte was analyzed for, but was not detected above the adjusted samplequantitation limit due to contamination from an outside source such as laboratorycontamination.
J The analyte was positively identified but the associated numerical value may notrepresent the actual concentration of the analyte in the sample due to analyticalbias in precision or accuracy, or because the resulting concentration has beenreported at a confidence level less than 99%.
UJ The analyte was not detected above the reported sample quantitation limit.However, the reported quantitation limit is approximate and may or may notrepresent the actual limit of quantitation necessary to accurately and preciselymeasure the analyte in the sample.
R The sample results are rejected due to serious deficiencies in the ability to analyzethe sample and meet quality control criteria. The presence or absence of theanalyte cannot be verified.

Appendix DHydrologic Evaluation of Landfill Performance Model
(HELP) V.3
\\Ussacls-ifosvr\SAC Industrial\Project\LEHR\WBH_Misc\WBHDrft7_9.dcic 25
Summary of Hydrologic Model
The evaluation of the water flux in the upper 25 feet of the WBH soils is aided by the use of theHELP (Hydrologic Evaluation of Landfill Performance) model. The HELP model was developedby the U.S Army Corps of Engineers to facilitate estimation of relative amounts of runoff,evapotranspiration, and leachate drainage that may be expected for a variety of land disposaloperations. The model is capable of simulating moisture flux through as many as 12 soil and/orwaste layers, and provides calculated volumes of drainage through selected layers. For thisanalysis two different scenarios were modeled. The goal for scenario #1 is to calculate the rate ofrainfall infiltration through the native soils on the WBH site, on an annual basis from 1974 to1998. The goal for scenario #2 is to calculate the rate of infiltration through the cap andcompacted soils after waste removal in 1999. The output file from the model is provided in theappendix along with a graphic representation of the model output.
The first situation (1974-1998) modeled two layers of soil from 0 to 60 inches bgs and 60 to 300-inches bgs. The 0 to 60-inch soil layer represents the native fine sandy loam of the area with avery shallow slope. The 60 to 300-inches soil layer represents the clay loam of the native soilsbeneath the former waste burial holes. Both layers are defined as vertical percolation layers. Nobarrier layers were used in the simulation. Percolation below 300 inches is assumed to reachHSU-1 groundwater.
The second situation (1999-2001) modeled three layers of soil, from 0 to 6-inches bgs (Cap), 12to 60-inches bgs, and 60 to 300-inches bgs. The 0 to 6-inch bgs soil layer represents thecompacted imported fill soil, following the WBH removal action. The compacted surface soil isa compacted is a Sandy Clay Loam. The 12 to 60-inch soil layer represents the fine sandy loamcompacted after waste removal in 1999. The 60 to 300-inch soil layer is the clay loarn of thenative soils beneath the former waste burial holes. All three layers are defined as verticalpercolation layers.
The climatological factors used in the model are mean daily precipitation, evaporation andtemperature. The climatological data compiled by Hydrosphere on the Davis 2 WSW Exp Farm,NCDC station was used in this analysis. The daily precipitation and daily temperature wereimported in to the model to generate accurate mean precipitation and temperature. The solarradiation was synthetically generated by the model for the Sacramento area. The soil propertiesused in this evaluation are porosity, bulk density, moisture content and saturated hydraulicconductivity all of which were calculated by default in the HELP model.
To calculate rainfall infiltration velocity for scenario # 1, the infiltration rate is divided by theporosity (11.4 inches / year) / (0.46) = 24.78 inches / year. For scenario # 1 24.78 inches per yearis the annual average infiltration rate.
Th calculate rainfall infiltration velocity for scenario # 2, (2.4 inches / year) / (0.46) = 5.2 inches /year. As this calculation indicates, surface grading and compaction reduced the rainfallinfiltration rate by approximately 80 %.
