2.0 SITE CHARACTERIZATION REPORT (SCR) ADDENDUM2.1 IntroductionThis addendum to the Site Characterization and Risk Assessment (SCR/RA), submitted to the Department of Environmental Quality (DEQ) on May 23,2017. This addendum is in response to the DEQ Voluntary Remediation Program (VRP) comment letter, dated September 18, 2017. The DEQ reviewedthe SCR/RA and provided comments. Responses to the DEQ comments are provided in the following table, and are submitted on behalf of the VRPapplicant.

Geology, groundwater elevation and direction and hydraulic properties,such as conductivity and porosity are being considered in the movement ofcontaminants across the site in groundwater. Note however, thatcontaminants at the site are metals, which are inorganic in nature andtend to bond with soil instead of dissolve. Therefore, the dominant factorsin contaminant movement are considered primarily for those constituentsthat are dissolved in groundwater. Depth to water is shallow andtopography, minus the berms, is relatively flat. Therefore, the conductivityis the primary determinant impacting the movement of contaminants.

Well gauging has been conducted several times during the course of thisproject and indicate that the local, shallow groundwater flow at the site isgenerally to the southeast. Local flow may be influenced by a sandpitlocated approximately 2,000 feet to the east.

The velocity range may be due in part to differences in subsurfacematerials at each well. Material at MW-3 is finer grained and may be fillmaterial from berm construction, the material at MW-5 is sandier,undisturbed, native soil.

2.4 Hydrology Conditions at the Site such as geology, groundwater elevation

and direction, and hydraulic properties are identified howeverthere is no discussion of how these conditions impact fate andtransport of contaminants.

Groundwater flow directions are opposite of what would beexpected based on topography. Please confirm groundwaterflow directions.

The groundwater velocities shown in Table 1, particularly 23.5ft/day, is extremely high for such a low hydraulic gradient at thesite. Please confirm the aquifer properties.

Prior to 1972, the site was formerly undeveloped land. The first improvedland use was in 1972.

The plan is to alter the site to accommodate indoor future use only.

2.2. Site Description and History Only operation of the LETS since 1972 is noted. Was there any

use of the Site prior to 1972? Please indicate if the Site will continue to be used as an outdoor

shooting range.

VB Law Enforcement Training Site (LETS) SCR Addendum 1 GER Project # 120-7347 Page 4

The four range floor samples were initially intended to determine if theremay be a concern on the range floor. The sampling in this addendum diduse the ITRC grid guidance for the range floor.

The results were thought to be anomalous based on uncharacteristicallyhigh concentrations, given the other concentrations determined nearbyand throughout in the same berms.During wet weather, the moisture tends to aggregate soils, making the soilaggregates more resistant to falling apart, therefore making the sievingmore difficult.

2.6.1 Soil Sampling and Analysis The ITRC – Characterization and Remediation of Soils at Closed

Small Arms Firing Ranges guidance describes a samplingapproach for the range floor using 22 x 22 foot grids with fivesubsamples from each grid. For berms areas trenching throughthe berm with samples taken from the trench walls issuggested. Please explain why GER used the grid method onthe berms and why range floor samples were taken from onlyfour locations.

For Tables 1A and 1B it is stated that “Results for A9 12-24, A1012-24 and A11 12-24 appeared anomalous. Therefore, were-sampled these points to determine if results were affected bydifficult sieving during wet weather. The resampled results arein blue under the first sampling results.” Please explain why theresults are thought to be anomalous and explain what is meantby difficult sieving during wet weather.

The site is not zoned for residential use. The applicant will place aresidential use restriction on the site. In this addendum, concentrationsthat meet or exceed residential/Tier II screening concentrations areconsidered in the risk assessment.

Off site groundwater exposure will be considered, based on the mostrecent data. If unacceptable risk is determined, there will be restrictionsplaced on off site down gradient receptors.

2.5 Conceptual Site Model The DRAFT CONCEPTUAL SITE MODEL does not consider future

use. Until a residential use restriction has been put in place,receptors such as on-site resident should be considered.

Off-site groundwater exposures need to be considered as MW-4and MW-5 are not located on the VRP Site and April 2017results show lead above Tier II screening levels.

ResponseDEQ Comment


Averages were used because the highest result or UCL would not berepresentative of each berm. This addendum will use the highest result orUCL from the range floor.

Table 4 indicates that averages were used. Only highest resultor UCL can be used.

This addendum considers the migration by additional sampling of the fivewells and three new wells.

It is stated that there was no off-site migration of anygroundwater contamination however lead was detected aboveTier II Screening Levels at MW-4 and MW- 5. Both of thesewells are located offsite beyond the VRP Site boundary.

General Comments

This statement is in error and should be a digging prohibition on the upper24 inches of the berms.

3.9.1 Commercial UseThis section contemplates land use controls that prohibit surfacedigging below 4 feet. What is the reason for prohibiting diggingdeeper than 4 feet when most contamination is located in the upper24 inches of the berms?

All monitoring wells were developed to maximize the yield and deliverwater with little to no turbidity. Development was performed by firstrecording the static water level and total depth. Next a submersible pumpwas used to overpump each well until the water ran clear. Depth tobottom of well was again measured to confirm that less than 10% of thescreen was occluded by sediments. Prior to sample collection, depth to water was measured in each well withan electronic water level meter. Liquid levels were measured to the nearest0.01 foot from a permanently marked survey point on the top of each wellcasing to allow measured values to be directly compared to a commondatum. Measurements made in the field included depth to water, and totalwell depth. From this, the volume of standing water was calculated. Threeto five well volumes were removed from each well using a cleanpolyethylene bailer.Groundwater samples were collected as follows: a separate, cleanpolyethylene bailer was used for each well. The bailer was gently loweredinto the top of the well until just filled. At this point, the bailer was slowlyremoved and the contents emptied into the appropriate sample containersfrom discharge from the check valve on the bottom of the bailer. Based on the newly installed wells and an updated well survey, wells MW-4and MW-5 are cross-gradient to slightly upgradient of MW-3.

2.6.2 Groundwater Sampling and Analysis Please provide details on groundwater sampling methods, to

include at a minimum well development, purge methods andrates, sample collection methods (i.e. low flow pumps, bailers,etc.)

It is stated that “Lead was identified in wells MW-3, MW-4 andMW-5, but at significantly lower concentrations in wells MW-4and MW-5. Based on the concentration difference from MW-3 toMW-4, lead in groundwater is dissipating significantly over arelatively short distance, approximately 100 feet, from MW-3 toMW-4. Based on these concentrations, the lead has not and willnot migrate to the down gradient residences. Only Ni and Znwere detected in the Dissolved Metals.” Figure 5 shows MW-3and MW-5 to be up-gradient or cross gradient of MW-3therefore this statement does not appear to be accurate.

ResponseDEQ Comment


The sampling of the range floor was conducted during a two-week periodin January 2018. Therefore, no sample dates are included in the figures.Two rounds of groundwater sampling were conducted in 2018. The samplecollection dates have been added to the groundwater figures.

Please include the date samples were collected on each figureportraying or utilizing sample results.

Dates each figure was created are now included on each figure. Please include the date each figure was created on each figure.

Well MW-3 is located in the toe, or base of Berm C. Additional wells havebeen placed beyond the berms to delineate contamination and define anyareas to be addressed in the remedial action plan.

How far away is MW-3 from BERM C? Contamination beyondthe berms will need to be delineated to define areas that needto be addressed in the remedial action plan.

Boring and well locations were selected to span across the site, andinclude upgradient and down gradient locations. MW-6 was installed as anew background well as MW-1, the original background well, iscross-gradient. MW-7 and MW-8 were located as far downgradient aspossible and close to the adjacent residential neighborhood.

Please discuss the reasoning for the boring and well locations.

Sampling parameters were selected based on known site use and potentialcontaminants. These include: lead (primary constituent of a projectile),antimony (increases hardness), arsenic (present in lead; a small amount isnecessary in the production of small shot since it increases the surfacetension of dropped lead, thereby improving lead shot roundness), copper(jacket alloy metal), and zinc (jacket alloy metal). These items werediscussed with DEQ on December 13, 2016, as the specific sitecontaminants that would potentially be present, based on the knownspecific site use. Given that the LETS was the first improved land usebefore which time the site was undeveloped land, and the site use waslimited to include only bullets, and there was no solvent use or otherpotential contaminants present on site, the sampling parameters reflect allpotential site contaminants.

As discussed in our meeting on December 13, 2016, andincluded in the review of Meeting Minutes dated 12-20-16,please provide justification for the limited list samplingparameters.

2.2 Site Sampling EventsOn January 17, 2018, three additional conventional 2-inch diameter groundwater monitoring wells were installed. Soils were logged during drilling. Thesample locations were identified as MW-6, MW-7 and MW-8, as shown on Figure 1. Well diagrams for the monitoring wells are contained in Section 6.The wells were constructed using a five-foot section of schedule 40 PVC pipe and a 10-foot section of 0.010-inch slotted well screen. After installation ofthe well, a coarse sand filter pack was installed to approximately one foot above the top of the well screen. A bentonite seal was then placed from thetop of the filter pact the ground surface. The groundwater monitoring wells were completed to a depth of approximately 13 feet bgs, with a PVC stick upof approximately 2 feet. The wells are protected by locked watertight well caps. The new groundwater monitoring wells were developed at the time ofinstallation to remove fine grained material and ensure proper connection with the shallow groundwater aquifer. During drilling, groundwater wasobserved at an approximate depth of 4-6 feet below grade. Additionally, between January 12 and 26, 2018, GER conducted additional range floorsampling. Sampling events conducted on this site include:


January 2018 - GER collected six soil samples, two at each of three new monitoring well locations, MW-6 through MW-8, during installation.One groundwater sample was collected at each of new wells and the original five monitoring well locations, MW-1 though MW-5. Figure 1 showsthe locations of the monitoring wells/samples collected in this study. Section 7 contains laboratory results.

January 2018 - GER collected surficial soil samples from the range floor using a hand auger between January 8-26, 2018. Figures 2-4 show thelocations of the samples collected in this study. Section 7 contains laboratory results.

February 2018 - GER collected a second set of groundwater samples from the monitoring wells using dedicated bailers. A duplicate sample wascollected at well MW-3, and designated as MW-9. Section 7 contains laboratory results.

April 2018 - GER collected groundwater samples from all monitoring wells using dedicated bailers.

2.2.1 Soil Sampling and AnalysisThe January 2018 study involved collection of soil samples from the monitoring wells. These samples were collected at the 0-6” below grade intervaland 48-60” interval. The January 2018 study also involved soil sample collection from the range floor with a hand auger. The sampling strategy andsample processing was based on the guidance provided in the Interstate Technology and Regulatory Council (ITRC) 2003 Technical and RegulatoryGuidelines, Characterization and Remediation of Soils at Closed Small Arms Firing Ranges and Air Force Center for Environmental Excellence’Technical Protocol for Determining the Remedial Requirements for Soils at Small Arms Firing Ranges (2000).The range floor was divided into rows, starting with row “D”, closest to the backstop berm and ending with row “L”, furthest from the backstop berm.Each row was then subdivided into a into 25’ gridded sections with an “X” pattern within each grid, each of the corner sub samples spaced 5 feet fromthe nearest grid edges and the center sub sample at the center of the grid for composite soil sampling (approximately 125 sample locations). Five subsamples were composited. Range floor soil samples were processed using two stainless steel sieves to sort out heavier particles. Sieve sizes usedwere a 9.5 millimeter (mm) or 3/8” and (2mm)/#10 mesh. All samples were placed in clean, laboratory provided containers, sealed with Teflon linedlids, preserved on ice and forwarded to a laboratory for analysis using chain-of-custody controls. Only the material that passed through the finersieve was collected and sent for analysis. As stipulated by DEQ samples in each grid were collected from surface soils only (approximate depth of 0-12” below ground surface or bgs). Gridswere numbered from 1-7, on the east side of the center sidewall berm/Berm B. Grids were numbered 8-14, on the west side of the center sidewallberm/Berm B (see Figures 2-4). Figures 2-4 show the antimony, arsenic, and lead results, respectively, in terms of less than VRP Tier II ScreeningConcentrations (green), meeting or greater than VRP Tier II Screening Concentrations (yellow), and meeting or greater than VRP Tier III ScreeningConcentrations (red).Generally, the metals expected to appear based on the use of the facility include: lead (primary constituent of a projectile) antimony (increases hardness) arsenic (present in lead; a small amount is necessary in the production of small shot since it increases the surface tension of dropped lead,

thereby improving lead shot roundness) copper (jacket alloy metal) zinc (jacket alloy metal)


Based on site history and previous sampling, only metals that were previously identified in soil, that met or exceeded VRP Tier II ScreeningConcentrations, were selected for analysis. These metals include: arsenic (As), antimony (Sb), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb),silver (Ag), and zinc (Zn). The analytical method used was EPA SW-846, Method 6010.Soil results from the January 2018 monitoring well soil sampling event are tabulated in Table 1A. Soil results from the January 2018 range floor soilsampling event are provided in Table 1B. Table 1C provides a summary of the monitoring well soil samples compared to VRP ScreeningConcentrations. Tables 1D and 1E provide a summary of the range floor soil samples to VRP Screening Concentrations, for the east and west sides ofthe center sidewall berm, respectively. Sampling generally revealed the following. Five metals: As, Cr, Cu, Pb, and Zn were identified in monitoring well 0-6 inch soil samples at detected concentrations.

Four metals: Cr, Cu, Pb, and Zn were identified in monitoring well 54-50 inch soil samples at detected concentrations. Only Cr exceeded VRP Tier II screening concentrations in the 0-6 inch and 54-60 inch interval. No analytes met or exceeded VRP Tier III screening concentrations.

Three metals: Sb, Cd and Ag, were NOT identified in any of the monitoring well soil samples.

Six metals: As, Sb, Cr, Cu, Pb, and Zn were identified in range floor soil samples above laboratory detection limits. On the eastern segment of the range floor, Cr, Cu, and Zn exceeded VRP Tier II screening concentrations. On the eastern segment of the range floor, As, Sb and Pb exceeded VRP Tier III screening concentrations. On the western segment of the range floor, As, Cr and Pb exceeded VRP Tier II screening concentrations. On the western segment of the range floor no analytes met or exceeded VRP Tier III screening concentrations.

Two metals: Cd and Ag, were not identified in any of the range floor soil samples.

Metal concentrations identified during berm soil sampling events generally were within, and sometimes less than the observed range and average ofconcentrations identified in the eastern U.S. in the United States Geological Survey (USGS) publication, “Element Concentrations in Soil and otherSurficial Materials of the Coterminus U.S.” (Shacklette and Boerngen, 1984). The exception is lead, which exceeded the average concentration of 19milligrams per kilogram (mg/Kg) reported in this publication. For reference, the following is a summary of the range and average of backgroundconcentrations reported in for elements in soils, per this document. Note there were no concentrations provided for Cd or Ag in the publication.

2.6.2 Groundwater Sampling and AnalysisThe January 2018 sampling involved the installation of monitoring wells MW-6, MW-7 and MW-8, on January 23, 2018, and groundwater samplecollection at sample points MW-1 through MW-8, including collection of a duplicate sample at well MW-3, on February 9, 2018. Following monitoringwell installation, the new wells had been allowed to stabilize for 24 hours prior to sample collection. Prior to the collection of groundwater samples,the wells were purged of at least three well volumes of water. All groundwater samples collected were placed in clean, laboratory providedcontainers, sealed with Teflon lined lids, preserved on ice and forwarded to a laboratory for analysis using chain-of-custody controls. Based on thesite history, groundwater was analyzed for the same Metals as anayzed for in soil using EPA SW-846, Method 6010. Monitoring well water samplingconducted on February 9, 2018 identified the following metals: As, Cr, Cu, Pb, and Zn. None of these were identified at concentrations exceedingVRP Tier II concentrations in February 2018.A second round of groundwater sampling was conducted on April 6, 2018, including collection of a duplicate sample at well MW-3. Groundwaterresults from each sampling event to date, by GER, are tabulated in Tables 2A and 2B. A comprehensive comparison of all groundwater samples toVRP Concentrations is tabulated in Table 2C. Metals identified in groundwater were: As, Cr, Cu, Pb, and Zn. Three metals: Sb, Cd, and Ag were notidentified in groundwater. The metals As and Pb were identified at concentrations exceeding VRP Tier II.

2.7 Summary of Data The City of Virginia Beach has operated a Law Enforcement Training Site, ‘LETS’, which includes a Small Arms Firing Range, since 1972. Constituentsidentified in soil, groundwater and sediment are metals. Some metals detected in soil were identified at low levels and are likely to be naturallyoccurring. The on-site inspections and sampling procedures have identified that metals from the bullets used at the LETS firing range are the source ofcontamination on the subject property. These metals are predominantly located in soil within Berms A, B and C. There are lower concentrations ofmetals in shallow soil along the range floor, with isolated higher concentrations located closer to the berms. The following paragraphs summarizeanalytes identified in soil and groundwater that exceeded a Tier III Screening Concentration in soil or Tier II Screening Concentration in groundwater.

2.7.1 Soil Data Discussion Monitoring well soil data showed that only Cr exceeded the VRP Tier II Screening Concentration, but was well below the VRP Tier III ScreeningConcentration. These concentrations at both 0-6 inches and 48-60 inches, were consistent with Cr concentrations identified in the soil analyzed fromthe original five monitoring wells.Range floor soil sample data indicates that the VRP Tier III Screening Concentrations were exceeded closest to the berms.

On the eastern segment of the range floor, Cr, Cu, and Zn exceeded VRP Tier II screening concentrations. On the eastern segment of the range floor, As, Sb and Pb exceeded VRP Tier III screening concentrations. On the western segment of the range floor, As, Cr and Pb exceeded VRP Tier II screening concentrations. On the western segment of the range floor, no analytes met or exceeded VRP Tier III screening concentrations.

Therefore, constituents of potential concern (COPC) were identified in range floor soil on the subject property and include As, Sb andPb, on the eastern section of the range floor. Drawings were completed for the COPC in soil along the range floor. Drawings are color coded.Drawings 2-4, respectively, illustrate antimony, arsenic and lead concentrations along the range floor. The color green represents all COPC below


VRP Tier II Screening Concentrations. The color yellow represents all COPC concentrations that met or exceeded a VRP Tier II ScreeningConcentration. The color red represents all COPC concentrations that met or exceeded a VRP Tier III Screening Concentration.2.7.2 Groundwater Data DiscussionEight groundwater samples (monitoring well samples MW-1 through MW-8) were collected on February 9, 2018. All groundwater samples wereanalyzed for the same select group of TAL Metals (Total Metals) tested for in soil, including: As, Sb, Cd, Cr, Cu, Pb, Ag and Zn. This sample eventincluded collection of a duplicate sample at well MW-3. The February sampling event identified: As, Cr, Cu, Pb and Zn. The February sampling eventdid not identify any COPC. Drawings 5-9 illustrate the various constituents identified in groundwater for the February 2018 sampling event. A second round of groundwater samples was collected and analyzed for the same Total TAL Metals group on April 6, 2018. The April sample eventdid not include a duplicate sample. The April sampling event identified: As, Cr, Cu, Pb and Zn. The As concentration at wells MW-1, MW-7 and MW-8exceeded the VRP Tier II As concentration. The Pb concentration at wells MW-2, MW-5, MW-6 and MW-7 exceeded the VRP Tier II Pb concentration.Therefore, the groundwater COPC identified in April 2018 include: As and Pb. Maximum constituent groundwater concentrations are summarizedboth above in Table 2C and in Table 3A. A drawing was completed for the COPC in groundwater and results in boxes are color coded in the sameway as done for the soil illustrations. Drawings 10-14 illustrate the various constituents identified in groundwater for the April 2018 sampling event.

3.0 RISK ASSESSMENTAll soil and groundwater sampling results collected on the subject property were evaluated in accordance with the VRP guidance documents. Thisincluded a comparison of field data to Tier I, Tier II and Tier III Concentrations as applicable. These screening concentrations are used to evaluate theseverity of contamination on the subject property. In Tier I screening, samples collected from the subject property are compared to background samplescollected from nearby areas that have not been affected by the substances of concern. If concentrations from the affected areas do not exceedbackground concentrations, the site is considered acceptable; if Tier I or background concentrations are exceeded Tier II screening is performed. Tier II screening involves comparing the maximum contaminant concentrations found on the site to media-specific values contained in the VRP guidancedocument. Tier II screening is generally associated with unrestricted-use sites such as residential development, schools, day care centers, hospitals,nursing homes, parks and agricultural areas. If the maximum contaminants found on the subject property exceed Tier II concentrations, Tier IIIscreening is performed. Tier III screening is based on site-specific analysis that weighs current and potential exposure scenarios for the population(s) ofconcern and characteristics of the affected media. Tier III screening is generally used for sites that are or will be formally restricted to a specified use.Tier III screening cannot be used for unrestricted-use (i.e., residential) sites. In this case, the site is commercial (institutional) and down gradient sitesare residential and therefore, Tier III screening was only performed for soil, which does not migrate down gradient. Tier II screening was performed forgroundwater. The closest down gradient sites are at 2610-2650 Hartley Street and 2304-2310 Charing Cross Road. The closest residence, at 2630Hartley Street is approximately 220 feet southeast of the subject property. There are no known water potable wells at these properties. Additionally, theCity supplies these properties drinking water. A visual survey and Freedom of Information Act (FOIA) inquiry with the Virginia Department of Health(VDH) indicated that there are no irrigation wells at these properties. The FOIA reply is attached, following Section 4.0.

3.1 Qualitative Risk AssessmentA site qualitative assessment revealed COPCs exist in soils and groundwater on the subject property. Based on information obtained from current andprevious site work, Tier II and Tier III screening assessments were performed for soil and groundwater. Soil and groundwater concentrations exceededVRP Tier II Screening Concentrations. However, the subject property is commercial and is buffered by a wooded area that is owned by the City andextends approximately 200 feet. Residential development is located adjacent to the wooded area. The analytical results for the three new wells showthat only Cr was detected exceeding Tier II concentrations. Chromium concentrations in the downgradient wells (MW-7 and MW-8) were generally


similar to the background well (MW-6), and the concentrations in both the shallow (0-6 inch) samples and deeper (54-60 inch) samples were similar.These results suggest that the concentrations of constituents identified in soil at these wells likely represents natural background concentrations. Anyresulting risks from COPC in soil on site can be managed through site restrictions (Health & Safety Plan, digging and land use prohibitions).On site groundwater risks will also be managed through site restrictions, as appropriate. Down gradient groundwater risks will be managed through theCity clarification of its drinking water ordinance section 37-5, which requires connection to public water supply where available. The applicant willrequest a letter from the City’s director of public utilities to clarify this ordinance and prohibit groundwater use in the area down gradient of this VRPsite, given that this area is and has been supplied with public water for the past 20 years. Table 3 provides a summary of the soil screening assessment.Table 3A provides a summary of the groundwater screening assessment.

3.1.1 Summary - Qualitative Risk AssessmentBased on the qualitative risk assessment, the COPCs were identified as provided in Table 3 for soil and Table 3A for groundwater. Given the existingand future site use, Tier III soil COPCs were retained for on site use. The VRP applicant, the City of Virginia Beach, also owns the wooded propertydown gradient of the defined VRP area. This wooded area extends approximately 200 feet from the back berm. Based on zoning, historic andcurrent use, all properties down gradient from the from City-owned property are expected to remain residential in nature.

3.2 Exposure Pathways3.2.1 Selection of Receptor Populations and Exposure PathwaysThe subject property is currently a secured, municipal facility. The subject property is proposed for continued municipal use. Based on the currentand proposed land use the various on-site receptors and exposure pathways were either selected or excluded for further assessment. Table 4 belowprovides the rationale for each on site receptor and exposure pathway considered.

3.2.2 Selection of Receptor Populations Exposure Pathways - OffsiteThe properties surrounding the subject property include municipal development use to the northeast (up or cross gradient) and residentialdevelopment to the east and southeast (down gradient). Based on the current and expected future land use the various down gradient receptorsand exposure pathways were either selected or excluded for further assessment. Table 5 below provides the rationale for each off site receptor andexposure pathway considered.

3.3 Exposure Point ConcentrationsAs stated above, the maximum site concentrations identified in well water will be the exposure point concentration (EPC) for offsite down gradientsites. Note: Lead is currently not included for Quantitative Risk Assessment (QRA) in the Virginia Unified Risk Assessment Model (VURAM). Since leadis a COPC, because a reference dose (RfD) value for lead is not available and VURAM does not calculate for lead, the U.S. Environmental ProtectionAgency’s (EPA’s) Technical Review Workgroup for Lead (TRW) Adult Lead Methodology (ALM) model was used to derive an exposure level thatsatisfies the risk reduction goal. The ALM is a mathematical equation used by EPA to predict the lead concentration in soil that would be appropriatefor non-residential areas (for example, industrial or commercial areas) where children are not likely to live or play. Since the subject property isinstitutional (commercial) in use, the ALM is appropriate. In this model, adult exposure to lead in soil is addressed by evaluating the relationshipbetween lead concentration in site soil and the blood-lead concentration (PbBs) in the developing fetuses of adult women. The ALM generates aspreadsheet for each exposure scenario evaluated (i.e., commercial, construction worker). The spreadsheet outputs the probability that blood-leadconcentrations in the fetus will exceed 10 micrograms per deciliter (µg/dL) blood lead concentration. The target probability for 10 µg/dL is 5%. Given alead concentration in soil of 8,800 mg/kg, the probability is unacceptable at 63.8%. Section 8 presents the spreadsheet.

3.4 Risk Assessment MethodologyThe Virginia Unified Risk Assessment Model was used during the risk assessment calculation process for soil for arsenic and antimony. Specific to lead,the ALM was utilized (see Section 8). The toxicity assessment was conducted using both carcinogenic and non-carcinogenic toxicity factors as required.The exposure point concentrations for soil and groundwater are found in Tables 3 and 3A.

3.5 On Site Risk Assessment and Exposure CalculationsDetailed risk exposure calculations are provided below and described in this section. VRP regulations cite 10-5 as a risk goal for individual carcinogens,not to exceed a site risk of 10-4 for all carcinogens. The National Contingency Plan (NCP) (U. S. EPA, 1990) cites an acceptable range of 10-5 to 10-4 fortotal carcinogenic risk with a point of departure of 10-5.The carcinogenic constituents excess lifetime cancer risk associated with all constituents, is within the acceptable range. Fornon-carcinogens, an unacceptable risk is defined as a hazard index greater than one for contaminants affecting the same target organ. Thenon-carcinogenic constituents hazard quotients for all constituents are less than one, except for ingestion exposure for theconstruction/utility worker, which exceeded 1.For lead, we input the maximum concentration found in the range floor samples into the ALM to predict PbBs to provide one indication of theassociated lead exposure for both current and potential future populations. The Centers for Disease Control and Prevention (CDC) identified a bloodlead concentration level of 10 µg/dL as the level of concern above which significant health risks occur. For lead, the toxicity assessment is based onexceeding the 10 µg/dL blood lead concentration. The ALM converts the prediction of blood lead level to a risk estimate, expressed as the probabilityof exceeding a PbB level of concern. A utility project would only last approximately 3 weeks. The proposed construction project will last 12 to 15weeks. At the most conservative, the 15 week exposure at 6 days per week would be 90 days. The commercial worker at this site (City LawEnforcement Officer) trains on the range twice yearly to maintain qualifications. Assuming the exposure is over a two week period for 6 days per week,the exposure frequency would be a maximum of 12 days. Risk for exposure to lead in soils is interpreted in terms of predicted blood lead concentrationrather than a Hazard Quotient. The ALM equations were developed to calculate cleanup goals such that there would be no more than a 5% probabilitythat fetuses exposed to lead would exceed a PbB of 10 µg/dL. From the original SCR/RA, the concentration that is safe is 2,240 mg/kg,assuming a 219 day exposure. Since the exposure duration will be significantly less, and there is just this one hot spot, it is not likelythat short term exposure to this maximum concentration will present human health risks.

3.5.7 Commercial and Construction/Utility Worker Exposure to Soil Range Floor - The lead Construction/Utility worker risk from exposure contact with Lead in soil was assessed with the ALM. Given the soil leadconcentration of 8,800 mg/kg, and a 8 week (5 days/week) or 40 day exposure, the ALM probability of exceeding a PbB level of concern forworking in the area of the range floor was 2% to 7.5%. The Preliminary Remediation Goal (PRG) is 6,763 mg/kg to 12,262 mg/kg.In sum, if the Construction/Utility Worker exposure to the range floor soils is maintained at 40 or less days, the risk is acceptable. This limitationwill be placed for range floor construction.

On site, there were no defined carcinogenic risks exceeding 10-4. (NOTE: The non-carcinogenic constituents hazard quotient associated withsoil exposure exceeds the acceptable limits for construction workers ingestion scenario on the subject property. TheConstruction/Utility Worker exposure to lead in soil on the range floor generated an unacceptable probability, under current conditions. A Health andSafety Plan will be in place to avoid and limit potential construction worker ingestion exposure.)

3.8 Uncertainty AnalysisThere are always uncertainties associated with the preparation of a risk assessment. The uncertainties include those associated with the collection ofsamples as well as laboratory analysis. Perhaps the greater uncertainty relates to whether the most contaminated samples have been adequatelycharacterized. Because of the number of samples collected and analyzed during the site characterization work conducted on the subject property, theuncertainties surrounding the risk assessment have been minimized. We believe the risk assessment presented in this report provides a satisfactoryrepresentation of the risks associated with the subject property.

3.9 Proposed Site PlansThe subject property’s proposed use includes the following elements:

3.9.1 Commercial UseThe subject property is proposed to be a municipal law enforcement training site. As appropriate, institutional controls, i.e., a land use restrictionwill be placed on the site to restrict the site to remain commercial/institutional use to prevent the owner from liability. The site is alreadydeveloped. Planned new construction will remove a portion of Berm B to facilitate a new structure for indoor law enforcement training. All of BermsA and C, and the remaining portion of Berm B will remain in place and will be covered. This portion of Berm B may be utilized in the future, subjectto appropriate remediation of the soil. Documents will be recorded in the Certificate of Satisfactory Completion (Certificate) requiring the siteremain institutional (commercial), prohibiting digging into the berms, requiring the cover to remain on the berms and prohibiting surface diggingbelow 2 feet.


3.9.2 Potable Water SupplyThe shallow groundwater on the subject property will not be used as a potable water supply and will be deed restricted to prevent anygroundwater use by the owner of the subject property.

3.10 Proposed ActionsThe risk assessment performed for the subject property, as it exists today, identified a potential non cancer risk greater than 1 associated with soilexposure on the subject property. There are no known potable or non potable off site residential wells downgradient. No off site migration of anygroundwater contamination was identified during this investigation. The following paragraphs provide a framework for the proposed actions to mitigatepotential risks on site and down gradient.

3.10.1 Current/Future ResidentThe down gradient residents are connected to the municipal public water system. Although there is a lack of any off site risks currently, a letterwill be provided from the VRP applicant/City of Virginia Beach to the VDH requesting the prohibition of future well installation or groundwater usewithin a 1/2-mile radius of the VRP site. Since the VDH issues the requisite permits for wells, the VDH can prohibit well installation.3.10.2 Construction/Utility WorkersAlthough there is evidence of groundwater contamination on site, in order to protect construction workers from any potential risks, it is proposedthat trenching near the berms be prohibited. There are no utilities in this area of the site that would require any digging.

3.11 Conclusions to Risk AssessmentThis Risk Assessment has been completed on behalf of the City of Virginia Beach. The report was prepared in accordance with the VRP GuidanceDocument. The majority of contamination is present in the Berms, predominantly in Berm C. The subject property contains elevatedconcentrations of metals in soil. The subject property contains elevated concentrations of metals (lead) in groundwater. A Tier III qualitative riskassessment was performed for the subject property using the VRP Guidance Document. The COPC are listed in Table 3 and 3A. An exposure pathwayassessment was performed followed by risk exposure calculations to quantify the specific exposure risks. The following specific exposure risks wereidentified based on the on site concentrations identified: Construction/Utility Workers ingestion exposure to antimony and arsenic in soil on site. Construction/Utility Workers exposure to lead in soil on site.

Based on the limited extent of COPC in groundwater, and the lack of down gradient wells, there is no current or projected future down gradient risk.Excavations, if required to be performed in areas containing contaminated groundwater on site, will be short term. Potable water for the site willcontinue to be provided by the City. Groundwater on the subject property will be institutionally controlled in order to prevent future groundwaterexposure. The proposed site use addresses and mitigates the exposure risk identified in the risk assessment.

4.0 SUMMARY There is no risk from soils off site. There is potential risk from groundwater off site. This will be managed by contacting the VDH to prohibit future well placement. There is potential risk from exposure to soils within the subject property for Construction Workers, should there be any disturbance of the range

floor. This potential risk will be addressed with engineering and institutional controls, as necessary.

Narrative


Receipt The samples were received on 2/1/2018 9:22 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 0.0ºC.

Metals Method 6010C: The following sample was diluted because the initial analysis produced a slight negative result - the absolute value exceeded the reporting limit (RL): MW-4 (400-149029-4). Reporting limits (RLs) are elevated as a result.

Method(s) 200.7 Rev 4.4, 6010B, 6010C: The method blank for preparation batch 400-385113 contained Silver above the reporting limit (RL). None of the samples associated with this method blank contained the target compound; therefore, re-extraction and/or re-analysis of samples were not performed.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Narrative


Receipt The samples were received on 1/30/2018 9:33 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperatures of the 3 coolers at receipt time were 0.0º C, 2.7º C and 2.8º C.

Metals Method 6010C: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 400-384658 and analytical batch 400-385122 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.

Method 6010C: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 400-384684 and analytical batch 400-385122 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.


Method 6010C: The serial dilution performed for the following sample associated with batch 400-385122 was outside control limits: (400-148939-A-41-A SD)

Method 6010C: The serial dilution performed for the following sample associated with batch 400-385180 was outside control limits: (400-148939-A-61-A SD)
