Detectable concentrations of TPHmo were reported in samples collected from SBS, SB14, SB24, and SB25. <br /> Reported detectable concentrations of TPHmo ranged from 390 Ftg/Q in SB24 to 1,100 gg/Q in SB 14, located <br /> in the northern portion of the 33-by 100-foot leach field to the west of the marina office and store. <br /> ' Detectable concentrations of benzene were reported in the samples collected from SBI, SB2, and SB26. <br /> Reported concentrations of benzene ranged from 580 EzgIQ in SBI to 3,400 EigIQ in the sample collected from <br /> SB26, located in the vicinity of the formerly hand augered hole SB10(RESNA).7 <br /> Detectable concentrations of methyl-tert butyl ether (MTBE) and naphthalene were reported in the sample <br /> collected from SB26 at 130 and 2,600 Egg/Q respectively. <br /> TPH and BTEX were not detected in samples collected from SB15, SB21, SB22, SB23, and SB27. MTBE and <br /> Naphthalene were not detected in samples collected from SB21, SB22, SB23, SB24, SB25, and SB27. <br /> aHoliday Harbor <br /> ' Groundwater samples collected from the Holiday Harbor facility contained no detectable concentrations of - <br /> analyzed constituents. <br /> The analytical results for the grab groundwater samples collected in January and February are presented in Table <br /> ' 2. Complete laboratory results and chain-of-custody records are included in Appendices B-G. <br /> 3.4 DOMESTIC WELL WATER ANALYSIS RESULTS <br /> ' During the January sampling, detectable concentrations of unknown hydrocarbons were reported in samples <br /> collected from DW-1, DW-2, and DW-3. Reported detectable concentrations of the unknown hydrocarbon <br /> ranged from 490 Ezg1Q in DW-3 to 610 pig/Q in DW-1. According to Superior analytical, the concentrations <br /> appear on the gas chromatogram in the range of diesel but do not have the appearance of a diesel pattern. In <br /> order to confirm the type and presence of hydrocarbons in the active domestic wells, the February samples <br /> were analyzed using mass spectrometer. This second round of sampling conducted in February yielded non- <br /> detectable concentrations for any hydrocarbons within the C4 to C14 range as well as BTEX, MTBE and <br /> naphthalene. <br /> n:tiMst�vet,n�wt�t.� 8 <br /> ' i0133-00E-02 <br />
