Petroleum hydrocarbon vapors were not detected in the excavation or excavated soils until the excavator penetrated the water table at around 4 to 5 feet his. The excavated soils were segregated, placed on an impervious surface and covered in plastic sheeting. When excavation activities were concluded, 52.6 tons of soils exhibiting a TVA response of greater than 10 ppm were n placed into dump trucks and subsequently delivered to the Waste Management Springfield Landfill 3 in Composition, Florida. Positive instrument responses were observed in two of the six UST excavation wall samples, SB -03 a and SB -05 located adjacent to the damaged UST. The highest methane- corrected TVA response observed in the UST excavation wall samples was 35 parts per million ( ppm), observed in Sample SB- y 9 05. Positive instrument responses were observed in all four of the dispenser samples. The highest J methane -corrected TVA response ( 31, 000 ppm) was observed in the sample SB -09, collected from the southern -most dispenser. Positive instrument responses were also observed in the fuel c distribution line samples. The highest methane -corrected TVA response observed in the distribution line samples was 2, 280 ppm, observed in Sample SB -12 on the southeastern end of the site O D Of the remaining soil samples ( SB -14 throughSB -25), the following samples exhibited methane - corrected TVA responses greater than 10 ppm, 27 ppm at a depth of 2. 5 feet in SB -14, located west fJ and adjacent to SB -03 and the nodowestem comer of the UST area', 196 ppm at a depth of 3.6 feet in SB -19, located south of SB -09 and the southernmost dispenser, and 18 ppm at depth of 4 feet in SB- N 24, located east of SS -11. Benzene was detected in two samples ( SB -09 at 20. 3 milligrams per kilogram ( mg /kgj and SB -12 at y 0 018 mglkg). Xylenes ( total) were detected in five samples ( SB -05, SB -07, SB -09, SB -12' and SB- f 19). Only the highest concentrations of Benzene observed at SB -09 exceeded the FDEP residential N The three PAHs ( 1- methylnaphthalene, 2- methylnaphthalene, and naphthalene) were detected in Me SCTL. samples ( SB-07 and SB -09) above the FDEP residential SCTLs. The highest naphthalene concentration observed at SB -07 exceeded the FDEP residential SCTLs. In addition, the calculated n total benzo(a) pyrene equivalent concentrations for all samples were below the FDEP residential SCTL a` 0 of 0. 1 mg /kg. TPH was detected in 20 of the 25 samples. Only the highest concentration observed at c SB -09 ( 824 mg/kg) exceeded the FDEP residential SCTL of 460 mg /kg. E Groundwater analytical results for five of the seven wells sampled indicated no detection of any contaminant of concern above the FDEP GCTLS. tu Groundwater analytical results for MW -01, in the center of the former UST area, indicated the Q detection of several VOA and PAH compounds and TPH. Five VOA compounds, six PAHs, and lead exceed the FDEP Chapter 62 -777 FAG GCTLS. VOA compounds exceeding the GCTLS include benzene, ethyl benzene, toluene, trichloroethylene, and xylenes, total. PAH compounds exceeding the GCTLS include 2- methylnaphthalene, benzo(a) anthracene, benzo( a) pyrene, benzo( g h,i) perylene, indeno( 1, 2, 3- cd) pyrene and naphthalene. Lead was detected at 17.3 uglL, just above the 15 ug/L GCTL TPH was detected al 127, which is below the GCTL of 5, 000 ug /L. The results from one well ( MW -03) indicated the detection of trace concentrations of VOA and PAH compounds and TPH, but all were below GCTLS. The results indicate that the detected concentrations of ethyl benzene and total xylenes in well MW -01 exceed the FDEP Natural Attenuation Default Source Concentration ( NADCs), which are the FDEP action level criteria for active remediation. 3 -1 ew„ 6a. naro min, 452 bmtl <JfNSeII SPP rr_. am, u. io luro PackM Pg. 121  4.4.9 The area of exceedances above the FDEP residential SCTL Is mainly located between SB -07, SB -09, SB -12 and MW 01 for Benzene, 1- methylnaphthalene, 2- meMylnaphthalene, and naphthalene, and/ or xylene. Recommendations for active remediation for the area near SB -09 and the ( leaking UST include the proposed excavation to 2' - 3' depth and backfil with clean fill and brought back to existing grade soil. Approximate proposed excavation limits is shown on Figure 4. As noted above the groundwater flow direction at the site is west- southwest. A continued investigative approach is recommended downstream of MW -01 to determine if the groundwater flow has trace concentration of VOA, PAH compounds and TPH that exceeds FDEP GCTLs and NADCs, prior to active emaciation The proposed installation of four additional monitoring wells to provide more groundwater sampling and analyses for the detection levels of the VOA, PAH compounds and TPH is recommended. Approximate location of proposed monitoring wells is shown on Figure 7. The additional activities recommended to address GCTL exceeding values in groundwater include: collection and laboratory analysis of 2 rounds of
