1. INTRODUCTION This document presents the Soil Vapor Extraction (SVE) Pilot Test performed by EA Engineering, Science, and Technology, Inc. (EA) at the Bandera Road Ground Water Plume Site (Site) located in Leon Valley, Bexar County, Texas. EA performed the SVE Pilot Test for the U.S. Environmental Protection Agency (EPA) Region 6 as part of Task Order No. 0037-RICO-06TY. SVE is an in-situ remedial process that physically separates vapor phase contaminants from soil by the application of a vacuum on the subsurface vadose zone. Conditions that may affect the efficiency of SVE include the depth to the aquifer, permeability, porosity, moisture content, and temperature. SVE is typically most effective with volatile contaminants of concern.

2. OBJECTIVE The purpose of this document is to present the results of the SVE pilot test and evaluate the potential for selecting SVE as a remedial alternative. The primary contaminants of potential concern (COPC) are chlorinated solvents related to dry cleaning facilities: tetrachloroethene (PCE), trichloroethene (TCE), dichloroethene (DCE), and vinyl chloride (VC). In this pilot test, the performance of SVE was evaluated for soil from 0 to 10-feet bgs as well as the underlying karst bedrock (i.e., Anacacho Limestone and Austin Chalk), which is typically found from 10 to 80-feet bgs. SVE depends largely on the characteristics of the formation. If the effective porosity is low, the flow of air will be ineffective in extracting volatile organic compounds (VOC). The objectives of the SVE pilot test were to evaluate:

1. Air flow in the vadose zone under vacuum pressure 2. Evidence of induced vacuum influence in nearby wells 3. Concentrations of primary COCs in effluent 4. Viability of SVE as a potential remedial alternative

3. SITE BACKGROUND INFORMATION The Site is located within the City of Leon Valley, which is in the northwestern section of San Antonio, Texas (Figure 1). The Site encompasses an area approximately 1 mile long by ½ mile wide. The plumes are in commercial/industrial areas with residential homes nearby. The Site includes releases and sources from at least two dry cleaning facilities. Soil gas results indicate the presence of source material in the soil beneath or near buildings and in the vadose zone bedrock above the Austin Chalk Aquifer. Migration in the vadose zone bedrock is primarily via fractures. Once contamination reaches the Austin Chalk


ground water, it is transported via secondary porosity (i.e., joints, faults, and solution features). Pore space diffusion is also present, although at a much slower rate. Site related contaminants have not migrated to deeper water bearing zones (i.e., Buda Limestone or Edwards Aquifer). Additional information is provided in the Remedial Investigation Report (EA 2011).

4. SVE PILOT TEST PROCESSES This section describes the SVE pilot test processes, including the permitting requirements, equipment utilized, and testing procedures. 4.1 PERMIT BY RULE Vapors extracted from the vadose zone during the pilot test were processed through granulated activated carbon (GAC). Subsequently, emissions were discharged under the Permit by Rule exemption for remediation activities per Texas Administrative Code (TAC) Title 30, Rule 106.533. As required, TCEQ Form 20122 (Regional Notification, Standard Permits/Permits by Rule Relocation Form) and the required attachments were submitted to the TCEQ Region 13 Office, Air Section in San Antonio, Texas as notification of the pilot testing activities. The City of Leon Valley, Texas also received TCEQ Form 20122 and attachments as notification. 4.2 EQUIPMENT The following equipment were utilized during the test: vacuum source, vacuum measurements, water level gauging, and emissions treatment and discharge. Pro-Act Services Corporation (Pro-Act) of Ludington, Minnesota was subcontracted to provide and operate the SVE pilot test equipment. Pro-Act operated a self-contained SVE remediation unit fitted with a 40 horsepower (hp) positive displacement pump capable of producing 500 cubic feet per minute airflow at 10-inches of mercury (Hg) vacuum (Photographic documentation is provided in Appendix A-1). Vacuum was controlled by the addition of ambient air using a valve open to the atmosphere, or by the use of a re-circulation loop that allowed vacuum to be regulated without the additional dilution air. The test well vacuum was measured at the wellhead in inches of Hg and inches of water. Vacuum transmission between the test well and nearby wells was measured using a digital manometer (Photographic documentation is provided in Appendix A-1). The water level was measured in the test well in response to the vacuum being applied. Vapors extracted from the vadose zone during the pilot test were processed through two trailer mounted 1,000 pound (lb.) vapor phase GAC units provided by Pro-Act (Photographic documentation is provided in Appendix A-1). Monitoring and sampling of the SVE emission was conducted using sampling ports connected to the inlet and outlet


of each GAC unit. Photo-ionization detectors (PIDs) were used to monitor the SVE emissions. Summa canister samples were also collected for laboratory analyses. 4.3 PILOT TEST PROCEDURE Pilot tests were performed in a stepwise fashion. Vacuum was increased incrementally in the test well, while the vacuum were measured in observation wells. Each vacuum step test lasted approximately 10 to 20 minutes; readings were recorded in approximate 10-minute intervals. Monitoring wells and soil vapor monitoring wells were utilized to determine if vacuum transmission was occurring in the vadose zone. Vacuum applied to the test well was increased until either the maximum vacuum capability of the test equipment was reached or until it was determined that increases in vacuum were not yielding either increased soil vapor flow or vapor concentrations from the test well. During the initial portion of the test on USGS-42, vacuum was controlled using the re-circulation loop on the SVE blower. However, this resulted in the blower overheating. Subsequently, the protocol was changed and dilution air was used to regulate the vacuum on the test well. After it had been determined the maximum vacuum had been reached, the SVE test continued during which total flow, soil vapor flow, vapor concentration, depth to water measurements, and vacuum readings were measured at 10-20 minute intervals. At the end of each test, samples of the SVE emissions were collected for laboratory analysis using a Summa canister.

5. SVE PILOT TEST DATA The SVE pilot test was conducted on five ground water monitoring wells (i.e., USGS-42, DW-408, DW-415, DW-404, and DW-414) and two shallow vapor-monitoring wells (i.e., SB-103 and SB-204). Ground water monitoring well locations are presented on Figure 2; shallow vapor monitoring wells are located near USGS-42. Well construction details are presented in Table 1 and well construction diagrams are presented electronically in Appendix A-2. For each of the seven pilot test wells, data are presented in tabular form. The extraction rate calculation for PCE using the summa canister data are provided in tabular form in Tables 3 through 15. Figures 3 through 9 depict the layout for each of the SVE pilot test wells.

6. SOIL VAPOR EXTRACTION PILOT TEST RESULTS The results are presented in context with the SVE pilot test objectives presented in Section 2.


The SVE pilot test results indicate that vapor flow within the vadose zone soil and Austin Chalk was achievable when placed under a vacuum. 6.1 Vadose Zone Soil Results Vadose zone soil well SB-103 was screened from approximately 5 to 9-feet bgs. The extracted vapor flow ranged from 66 to 70 standard cubic feet per minute (scfm) when applying vacuum up to 54 inches of water column (WC) (Table 4). Vacuum influence ranged from no measurable vacuum at 25 ft (SB-104) to 0.30 inches WC (SB-204) at 29-feet. Vacuum influence of 0.1 inches WC was observed at a distance of 50 feet (AB-105). The range of observed vacuum influence is an indication that there is significant air flow variability within the clay/caliche soil matrix. The calculated PCE concentration in the extracted vapors of 34.4 mg/m3 indicates that VOCs can be removed from the soil matrix. Vadose zone soil well SB-204 was screened from approximately 1 to 3-feet bgs. The extracted vapor flow ranged from 55 to 76 scfm when applying vacuum up to 54 inches WC (Table 6). Vacuum influence ranged from no measureable vacuum at 16-feet (SB-201) to 0.20 inches WC at 29-feet (SB-104). This is an indication that there is significant air flow variability within the clay/caliche soil matrix. The calculated PCE concentration in the extracted vapors of 13.0 mg/m3 indicates that VOCs can be removed from the soil matrix. Given that the screened interval for this well is shallow, there was a potential for short-circuiting (i.e., air from the surface rather than the vadose zone). This was also evidenced by the low PCE concentrations in the extracted vapors from a well that was close to the source area. Vacuum applied to vadose zone soil wells SB-103 and SB-204 had little response in Austin Chalk well USGS-42, indicating that SVE in vadose zone soil would have little influence on the underlying bedrock. SVE of vadose zone soil is considered a viable remedial alternative. However, the variability in vacuum influence distance and the potential for short-circuiting should be considered appropriately. 6.2 Austin Chalk to Vadose Zone Soil Results Austin Chalk well USGS-42 was open hole from 45 feet to the top of the water table at approximately 80-feet bgs. The vapor flow ranged from 67 to 240 scfm when applying vacuum up to 136 inches WC (Table 2). Vacuum influence from bedrock to nearby vadose zone soil ranged from no measureable vacuum at 41-feet horizontally (SB-105) to 0.70 inches WC at 19 feet horizontally (SB-204). This is an indication that there is air flow variability between the Austin Chalk and the overlying clay/caliche soil matrix; however, it also demonstrates that there is a complete migration pathway. This migration pathway is demonstrated by the calculated PCE effluent concentration of 2,303 mg/m3, which indicates potential source material nearby. This test indicates that VOCs can be removed from the Austin Chalk and SVE is considered a viable remedial alternative.


6.3 Austin Chalk Results Austin Chalk well DW-408 was open hole from 53 feet to the top of the water table at approximately 100-feet bgs at the beginning of the test; the water table rose approximately 10-feet (i.e., to 90-feet bgs) during the test. The vapor flow ranged from 63 to 86 scfm when applying vacuum up to 109 inches WC (Table 8). Vacuum influence in bedrock ranged from 0.019 inches WC (USGS-42) at 374-feet to 2.1 inches WC (DW-415) at 222-feet. These results are similar to those in other test wells (i.e., DW-415, DW-404, and DW-414). There is good transmission at 200 feet within bedrock (see results for DW-408 and DW-415); vacuum influence at these distances (e.g., greater than 200 feet) are consistent with fracture dominated flow. However, vacuum influence was not observed at distances of 300 feet or more (see results for DW-408, DW-404, and DW-414). The calculated PCE effluent concentrations of 4.5 mg/m3 at DW-408, 1.95 mg/m3 at DW-415, 3.0 mg/m3 at DW-404, and to a lesser extent 72.7 mg/m3 at DW-414 indicate that the bedrock source is not nearby or is not in direct communication with the monitoring well. Therefore, utilization of these wells for SVE is considered marginal. SVE of Austin Chalk is considered a viable remedial alternative. The primary factor in implementation of SVE will be the location of wells in proximity to the source (e.g., USGS-42). Because the vacuum influence distance was greater than 200 feet, it is not considered a limiting factor.

Work Order(s)-----------------

Analyses included in this report:Air TO-15(SIM/Scan) ug/m3

Report NarrativeDue to sample dilutions the lowest possible detection limits were not obtainable for the compounds of interest. Dilution factors required and resultant sample carryover contaminated the analysis system which required stopping the analysis, doing system cleanup and then sample reruns. The high results of tetrachloroethene are also suspected of causing the slight excursion from the QC limits of the second LCS duplicate.

Reporting limits are adjusted for sample size and matrix interference.

Standard procedures for quality assurance and quality control were followed in the analysis andreporting of the sample results. The results apply only to the samples tested. This final reportshould only be reproduced in full.
