Canepa's Car Wash <br /> SVE Start-up Report <br /> November 30, 2004 <br /> Page 2 of 4 <br /> A sample was obtained from both the inlet (influent) and exhaust (effluent) for evaluation of the <br /> efficiency of the SVE system. In addition, vapor concentrations from the influent and effluent were <br /> concurrently measured with a PID to calibrate the PID for future field measurements. The influent <br /> laboratory sample was collected directly from port located between the vacuum pump and the burner. <br /> The sample was collected by filling a 6-liter SUMMA canister directly from the sampling port. The <br /> effluent laboratory sample was collected by drawing an air sample from the exhaust into a 6-liter <br /> SUMMA canister through a stainless steel tube, after using a vacuum pump to purge the tube. The <br /> sample containers were labeled, placed in a shaded box and delivered in accordance with chain-of- <br /> custody procedures, to AirToxics Ltd., in Folsom, California, on the day, of collection. <br /> LABORATORY RESULTS <br /> The laboratory samples were analyzed by the laboratory for total petroleum hydrocarbons (TPH) C5+ <br /> Hydrocarbons referenced to gasoline; and for benzene, toluene, ethyl benzene, and total xylenes (BTEX) <br /> by modified EPA Method TO- 14A. <br /> Laboratory analysis of the influent sample indicated that BTEX constituents were detected at <br /> concentrations ranging from 5 ,200 to 45 ,000 parts per billion by volume (ppbv), and TPH was detected <br /> at a concentration of 480,000 ppbv. Laboratory analysis of the effluent sample indicated that BTEX <br /> constituents were detected at concentrations ranging from 9.5 to 66 ppbv, and TPH was -detected at a <br /> concentration of 3000 ppbv. The laboratory analytical results are summarized below in Table 1 . <br /> Laboratory report sheets indicating analytical methods used, detection limits, QA/QC, and the results of <br /> the analyses are attached to this document. <br /> I <br /> Table 1 <br /> Air Sample Laboratory Analytical Results (October 7, 2004) <br /> Constituent: Benzene Toluene Ethyl m, p o- TPH <br /> Benzene Xylenes Xylenes <br /> Analytical Method—> Modified Modified Modified Modified Modified Modified <br /> T044A TO-14A TO-14A TO-14A TO-14A TO-14A <br /> Sample LD,. <br /> 1707C-Stcklnf-10/7/04 413000 45,000 5,300 162000 . 51200 4807000 <br /> 1707C-StckEff-10/7/04 55 66 9.5 38 11 3000 - <br /> Units: Analytical: <br /> ppbv = parts per billion by volume E, T, E, X = benzene, toluene, ethyl benzene, total xylenes <br /> ppm = parts per million TPH = total petroleum hydrocarbons <br /> PID Readiness <br /> Influent 163,000 nobv <br /> Effluent 1 ,000 nobv <br /> DESTRUCTIVE EFFICIENCY <br /> Using the influent and effluent concentrations of benzene, toluene, and TPH, destruction efficiency for <br /> the SVE system was estimated at 99 .83 , 99 . 82, and 99.35 respectively. <br /> PID CORRECTION VALUE <br /> The PID measurements of the influent and effluent air vapor hydrocarbon concentrations of and <br /> laboratory analytical measurements for TPH were compared to provide a correction factor for future PID <br /> measurements .
