CAMBRIA i hydrocarbons as gasoline (TPHg), benzene, toluene, ethylbenzene, xylenes (BTEX), and fuel oxygenates (MTBE,TAME, DIPE,ETBE, and TBA)by EPA Method 8260B Stockpile Sampling Dunng construction activities, pea gravel was placed into two temporary stockpiles onsite Cambria collected stockpile samples and they were analyzed for TPHg, BTEX, and fuel oxygenates The pea gravel was reused after replacement of product piping with permission from SJCPHS/EHD ANALYTICAL RESULTS Soil sample results are presented on Table 1 and TPHg, BTEX, and MTBE results are shown on Figure 2 The certified analytical report is included in Appendix A A summary of the data is presented below Samples P-2 through P-5, P-7, and P-8 contained TPHg at concentrations ranging from 2 7 to 220 parts per million (ppm) Benzene was detected in samples P-2, P-3, and P-8 at concentrations ranging from 0 020 to 0 066 ppm MTBE was detected (by EPA Method 8260B) in all soil samples at concentrations ranging from 0 015 to 0 42 ppm TAME was detected in soil sample P-8 at 0 038 ppm and TBA was detected in samples P-3, P-6, and P-8 at concentrations ranging from 0 0069 to 0 61 ppm CLOSING Based upon visual observations and the analytical results of soil samples dunng removal activities, petroleum hydrocarbons and fuel oxygenates were found in soils beneath the area of the replaced piping Based on the concentrations and locations, this soil impact appears to be associated with an old release documented in Fugro West, Inc 's April 19, 1995 Underground Storage Tank Closure Report The dispenser area was subsequently investigated and the results are documented in Enviros, Inc 's May 21, 1996 Soil Boring Installation Report Based on this information, Cambna does not recommend additional investigation of the soil near the dispenser area at this time 1359 2
