Prepared for ABERCROMBIE OIL COMPANY by ENSCI ENGINEERING GROUP, P.A. ENSCI Project No. ME16708 August 1, 1996 \ INTRODUCTION ENSCl Engineering Group, P .A. (ENSCl) has been contracted by Abercrombie Oil Company to perform site assessment and to implement remedial action of a petroleum fuel release at the Short Stop facility in Carrboro, Orange County (see Figure 1 ). A comprehensive site assessment (CSA) report was issued on February 17, 1994. The results of the CSA activities indicated that the release has affected soils and groundwater beneath the site. This report presents the results of the quarterly groundwater monitoring event that was conducted on May 15, 1996. This is the third groundwater monitoring report submitted for this site. GROUNDWATER FLOW On May 15, 1996 ENSCl personnel inspected all monitoring wells installed during site assessment activities. One well, MW-1, could not be open due to damage to its cap. Accurate static water levels were measured in each of the other wells (MW-2 through MW-7) using an electronic water level nieter. Table 1 presents the water level data for the subject monitoring event. The water elevation data were used for the development of the water table elevation map presented in Figure 2. The map was used to evaluate the direction and gradient of groundwater flow in the water table aquifer. Groundwater appears to be flowing toward the south under an average hydraulic gradient of 0.003 feet/foot. This direction and gradient are consistent with the conditions recognized during the CSA inve.ttigation, . ' GROUNDWATER SAMPLE COLLECTION AND HANDLING Following measurement of water levels, each monitoring well was purged of a minimum of three well volumes of groundwater using an individual disposable bailer. The wells were allowed to recover to near static levels and water samples were collected in laboratory-prepared containers. Because MW-1 could not be opened, the well was not sampled. Groundwater recovery well RW- 1 was sampled instead. The water samples were stored on ice and shipped to a North Carolina certified environmental laboratory for analyses per EPA methods 601 aod 602 plus MTBE, Chain of custody protocol was followed for sample collection and handling. I /' \ w '), i ' GROUNDWATER SAMPLING ANALYTICAL RESULTS A copy of the laboratory report with the results of the May 15, 1996 sampling is provided as an appendix to this report. Table 3 summarizes the groundwater analytical results and compares the new data with previous results. As illustrated in Table 3, concentrations of dissolved typical gasoline constituents in the wells have generally decreased with respect to previous sampling events. An isoconcentration map depicting the analytical results for the May 15, 1996 sampling is provided for MTBE (Figore 4). Isocon maps for other constituents are not provided for this quarter due to the lack of sufficient data above detection limits. The presence of tetrachloroethane and trichloroethane has been detected in MW-5 and RW-1. No substantial increase is noted with respect to the last monitoring event. The origin of these contaminants is unknown; however, they are not believed to be related to the release of gasoline at the Short Stop site. No free product has been observed at the site. SOIL SAMPLING ANALYTICAL RESULTS On May 21, 1996 three soil samples were collected from three borings advanced to an average depth of 4 feet below land surface at the locations shown on the enclosed site map (Figure 5). The samples were laboratory tested for total petroleum hydrocarbons by methods 5030 and 3550. Table 2 presents the analytical results for the soil sampling event. REMEDIATION SYSTEM PERFORMANCE Because of mechanical problems, the SVE system installed at the site was not in operation during the period reported. The system was repaired and returned to operation during the second week of July, 1996. ' This report was prepared by: ENSCl ENGINEERING GROUP, P.A.

No apparent ''·:-container problems ~ noted upon receipt. Prior to and during analysis. the samples Mre kept under lock with access only to authorized personnel of . Enthalpy Analytical, Inc. The bag sample \WS analyzed for benzene, toluene, ethylbenzene, xylene, (BTEX) and total petroleum bydrocarl>ons (TPH) using EPA Method 18 analytical _ __ procedures. The BTEX constituents v.ere referenced to a certified B'I'EX" gas ·· ' standard and the TPH was referenced to a certified isooctane standaid The BTEX compounds were individually identified and reported as ppmv. The TPH was determined by summing the area of each detected peak except methane and · referencing the isooctane curve. The TPH is 1eported ppmv as iscxx:tane. All samples and standards are injected into the GC using a VlCI lO.port gas loop injection system. All samples were separated using a Supelco SPB-5 30M x , 0.53mm capillary column. The analyzer v.m a Hewlett-Packard 5890 Series II -: Gas Chromatograph equipped with a flame ionization detector using hydrogen as the carrier gas. The following table shows approximate retention times for each analyte. .

If the two xylene isomers are present ( o-and p-). the area of each peak is summed and the software assigns a retention time based on the midpoint between these peaks.
