Additional borings may be drilled based upon findings of the initial field screening samples. One soil sample at eight feet (ust above the water tabte) will be collected from each boring during the investigation. o Soil samples will be screened for the presence of hydrocarbon vapors using a Foxboro OVM-128 flame ionization detector (FID) and a detector tube and wash bottle. A measured amount of soil will be paced in the wash bottle with a defined volume of water. Air will be sparged through the water/soil mixture in the wash bottle to strip out the volatile hydrocarbons, which will be measured with the detector tube. Four of the soil samples will be submitted for total petroleum hydrocarbons (TPH) and benzene, toluene, ethylbenzene, total xylenes, and naphthalene (BTEXN) by EPA methods 8015 modified and 8020, respectively. o The eight borings, described above, will be completed as eight groundwater and soil-gas sampling wells. The soil-boring field-screening results will be used to determine the monitor/sampling well locations. The groundwater and soil-gas sampling wells will be screened across the static groundwater level so they can be used as both groundwater monitoring wells and soil-gas sampling points. The two-inch diameter monitoring wells will be installed to depths of approximately L4 feet below ground surface (bgs) and will consist of 10 feet of 0.02 slot screen in a sand pack with a three-foot bentonite seal at the surface. The well/sampling point locations will be identified in the field in consultation with rhe DERR project manager. Proposed locations for the monitor wells/sampling points are shown in Figure 1. The wells will be developed by pumping and surging. o Maxim Technologies, Inc. (Huntingdon) will contact Blue Stakes and other appropriate utility companies to mark underground utilities prior to corlmencement of field activities. The soil boring, well installation, and well development will be performed by RC Drilling. Perform one quarterly groundwater sampling at the site: . After development, groundwater samples will be obtained from six selected new groundwater wells. The samples will be submitted for laboratory analysis of total petroleum hydrocarbons (TPH) and benzene, toluene, ethylbenzene, total xylenes, and naphthalene @TEXN) by EPA methods 8015 modified and 602, respectively. / ***:] if, rn or,-3^f_r:-i* * *;i-^)-.; r;i' 7' l,:l.l*' N:tChatwinDERRtliso.tnv "5 pft, ?ntl,r1,*.,k il { f"{'2}'' 1 Ms. Kate Johnson August l, 1995 Page 3 E) o One quarterly groundwater sample will be collected from each of the nine previously installed monitor wells (B-1 through B-11) using proper sampling protocol pursuant to Utah Administrative Code R31l-205 (1992). These groundwater samples will be submitted for laboratory analysis of TPH and BTEXN. Data from two downgradient wells (MW-l and MW-2) at the 7-11 station at 300 South and Main will be included in the Big-O data set. These wells are shown in Figure 1. For the cost estimate, it is assumed that these samples will be collected and submitted for analysis by Maxim. Develop a corrective action plan feasibility study for the site: o Evaluate the potential use of groundwater air-stripping trench, soil-vapor extraction (SVE), and/or bioremediation to remove petroleum hydrocarbons from soil and groundwater. A preliminary indication of the extent of contamination in groundwater is shown in Figure 2. o Field pilot tests for an insitu groundwater air-stripping trench and a horizontal soil-vapor extraction (SVE) system will be performed on-site to determine effectiveness of these technologies at the site. o Slug tests witl be performed on two of the monitor wells (B-5 and B-11) to obtain aquifer parameter information. The in situ groundwater air-stripping trench pilot tests will involve installation of one horizontal sparge line placed in a trench which is dug to a depth of 12 feetbgs. The horizontal sparge line will be constructed of two-inch diameter perforated or porous plastic pipe. The sparge line will be located at a depth of 11.5 feet or approximately two to three feet below the water table. The trench will be filled with washed pea gravel. A horizontal vacuum-extraction line will be placed in the same trench above the sparge line as shown in Figure 3. The extraction line will be installed 7.5 feet above the sparge line and 4.5 to 5.5 feet above the water table. The vapor-extraction line will be constructed of 2" diameter SCH-40 PVC screen. The vapor extraction line will be placed at a depth of four feet bgs, with one foot of gravel will be placed above the extraction line. An impermeable liner will be placed above the gravel in a keyed trench and backfilled with excavated material to seal the header from atmospheric leakage as shown in Figure 3. The air-stripping trench will be excavated by Robinson Transport of Salina, Utah. The objectives of the insitu air-stripping trench is 1) to treat groundwater flowing through the trench by sparging volatile organics (i.e., BTEX) from the N : lC h arw i nD E RRIB i g O. I nv groundwater, while it is contained in the trench and 2) to increase dissolved oxygen in the groundwater down-gradient of the trench. Three soil-gas/groundwater monitor points will be placed at distances of approximately five, 15, and 25 feet laterally away from the trench as shown in Figure 1 (these three wells are included in the eight listed above). Monitor wells B-3 and B-4 will also be used as monitoring points located 10 and 50 feet from the trench. Figure 1 shows a plan view of the pilot test layout. Figure 3 presents construction details of the sparge and vapor extraction lines and monitoring points. For the SVE pilot operation, the upper horizontal SVE line will be evacuated and monitor wells (B-5 and B-7) and the soil-gas/groundwater monitoring points will be used to monitor the vacuum effects of the SVE in the soil. The SVE pilot test will involve inducing a vacuum on the vapor extraction header using a regenerative blower rated at L27 scfm and 65-inches water gauge. The pilot tests will be run at flow rates of 40, 65, and 90 scfm. Changes in induced vacuum will be recorded at each monitoring point during each flow-rate test. The hydrocarbon vapor content will be monitored at the vacuum pump effluent for each flow-rate test. The vacuum change versus distance from the header to each monitor point will be evaluated to determine the lateral influence for effective soil vapor extraction at the site. The air-stripping trench pilot test, which includes both sparging and SVE, will involve injecting air from a compressor into the horizontal sparge line at approximately five pounds per square inch (psi) at flow rates of I0,20, and 40 standard cubic feet per minute (scfm). The SVE line will be operated at approximately 10 scfm greater than the sparging flow, or 20,30, and 50 scfm. changes in water level, induced pressure, dissolved oxygen, and hydrocarbon vapor content will be recorded at each monitor point during each flow rate test. These parameters will be evaluated to determine the effect of the air-stripping outside the trench. The estimated groundwater flow velocity at the site is about 0.03 feet/day for a groundwater gradient of 0.01 ft/ft. At this groundwater flow velocity, groundwater would require over five months to travel five feet to the nearest monitor point. However, the sparging action in the trench will increase the groundwater level in the trench raising the groundwater flow from the trench. A piezometer will be placed in the trench to measure the groundwater level in the stripping trench. 1 Ms. Kate Johnson August l, 1995 Page 4 N :lC harwi nlD ERRIB i gO. Inv I Ms. Kate Johnson May 26, 1995 Page 5 Soil and groundwater samples will be collected and arnlyzed to assess the potential for bioremediation at the site. Soil and groundwater samples will be collected from three areas at the site to evaluate site soil and groundwater chemistry. The samples will be collected from an upgradient area with no TPH contamination, an area of high contamination, and an area down-gradient of the contamination plume. Table 1 lists the parameters for soil and groundwater that will be analyzed. Soil and groundwater samples will be ar:,a,lyzed for physical, chemical, and bioremediation parameters at four separate laboratories. Soil and groundwater samples will be submitted to American West Analytical I-aboratory in Salt Lake City for chemical analysis other than TPH and BTEXN (see Table 1). The TPH/BTEXN analyses will be performed by Utility Testing [aboratory. Soil samples will be atalyzed for site-specific physical parameters at the Maxim Technologies, Inc. (Huntingdon) soil laboratory in North Salt Iake. Groundwater samples will be analyzed for biological parameters at the Richards Laboratory in Pleasant Grove, Utah. o Laboratory analytical costs for TPH/BTEXN analyses are approximately $76.50 per sample for soil or groundwater. I"aboratory analytical costs for bioremediation purposes are approximately $192.00 for soil analysis, $130.00 for groundwater chemistry, and $60.00 for biological parameters. Determine the effectiveness of the in situ groundwater air-stripping trench: o After initially testing the groundwater air-stripping trench determine the air- stripping trench effectiveness by operating the system for one month. Following the demonstration test the groundwater in wells B-4, B-5, B-7 and the three soil- gas/groundwater monitor points will be sampled and analyzed for BTEXN and TPH. Dissolved oxygen and microbial colonies will measure in the groundwater sample. o The off-gas from the in situ stripping trench will be sampled and analyzed for BTEX and TPH. Required air-quality permits for the demonstration test will be obtained. Prepare and submit a report on the additional investigations o The additional investigations report will describe the CAP feasibitity study and the stripping trench effectiveness demonstration.

Dear Mr. Chatwin: The Division of Environmental Response and Remediation (DERR) has completed its review of Maxim's request for a Work Assignment Amendment to Work Assignment Number EHLR-2 under contract #95-1024, due to the need for obtaining three additional quarters of groundwater monitoring data.

The enclosed Work Assignment Amendment # EHLR-2.A hereby formally approves a change in the scope of work, and a corresponding increase in the approved budget with an additional amended cost of $8,430.18. The amended total approved budget is now $11,240.24.
